8370R Tractor

The 7R, 8R, and 8RT Series Tractors feature two lighting package options:

• Standard 
• Premium

The cab lighting pattern provides 330 degrees of coverage while the hood lighting provides the remaining 30 degrees for completely programmable 360-degree, stadium-style lighting. This ensures there are no dead zones or lighting adjustments needed. The lighting configurations are available to match various applications and ensure maximum around-the-clock productivity.

Bulb housings are large, allowing for optimum total lumens and available light. The standard lighting packages use 65-W halogen bulbs, whereas the premium lighting package uses light-emitting diode (LED) lights. In the premium lighting package, these tractors take advantage of the high-performing and efficient LED technology.

The low- and high-beam driving/work lights are adjustable. Please refer to the electrical section in the operator’s manual for complete details on adjusting lights.

The premium lighting package replaces all previous halogen and HID lights with LED lights. The only lights that are not LED are the low-beam driving lights, they remain halogen. This allows each LED light to work at a lower temperature and no one light works harder than any other. The uniformity in LED coverage allows only one type of light output surrounding the tractor.

 

The lighting pattern in the premium package provides industry-leading performance in nighttime visibility. LED bulbs provide maximum brightness and a true color output for excellent field definition that is easy on the operator's eyes.

 

The LED lights provide 40 percent greater coverage width and 10 percent more light coverage in the rear. LED lighting packages use 45 percent less amps than standard halogen lights and have an increased life expectancy over HID lights which leads to lower costs of ownership over the life of the tractor.

 

NOTE: Lighting packages may vary depending on region.

Selecting a lighting mode/programmable lighting

Operators can quickly select a lighting mode on the steering console:

• Lights, off position  
• Road lights
• Field lights

The CommandCenter display allows operators to customize light settings. Operators can select only the lights they need or want for a given application and store these settings. The operator-programmed configurations can then be turned on or off with the push of a button on the CommandARM™ controls.

• Programmable field lights 1 
• Programmable field lights 2 
• Beacon light 
• Emergency flashers

 

NOTE: Road/loader lights are also referred to as high-mounted driving lights for use in front hitch applications that obscure the headlights. See the Attachments section.

The battery power saver feature is also standard. When the engine is off and the outside lights have been left on, this feature is designed to avoid battery run down.
 
After the lights have been left on for 30 minutes and the key is in the off position, the lights cycle or blink on and off five times as an alert. The lights continue to illuminate for one more minute and then automatically shut off to protect the battery.

Field-installed options

Field-installed options are also available. To find this information, use the Build Your own Configurator application for US/Canada or Build & Price in John Deere Sales Centre for Australia/NZ.

Programmable exit lighting

Another feature is programmable exit lighting. Exit lighting allows the lights outside the cab to stay on for up to 300 seconds.  They can be programmed in increments from 0 to 300 seconds.

 

Refer to the operator’s manual for complete instructions on programming field, driving, and exit lighting.

ACS overview

With ACS, John Deere has designed one of the most robust and full-encompassing steering system in the industry. Whether in the field or on the road, ACS reduces steering effort, which can result in reduced operator fatigue and can improve operator comfort.

 

There are four key features of the ACS system:

 

Dynamic road wheel offset:

• A gyroscope senses tractor yaw and can automatically make small steering adjustments to provide unprecedented line-holding abilities. Drive down a bumpy road and experience how ACS makes it easier to keep the tractor straight, even over rough terrain.  ACS delivers the ultimate in comfort.
• ACS works to prevent over-steering when a sudden obstacle causes the operator to make a quick steering reaction.

 

Variable ratio steering:

• Approximately 3.5 turns lock-to-lock at in-field speeds for quick headland turns.
• Approximately 5 turns lock-to-lock at transport speeds.

Elimination of steering slop and hand wheel drift:

• Steering wheel drift and slop are eliminated with the ACS electronic control system.

 

Variable effort steering:

• Steering wheel resistance automatically changes with ground speed to deliver light steering effort at slower speeds for less effort during headland turns, and higher steering wheel torque at transport speeds for better comfort.

 

A fail operational system

The ACS system is fail operational, which means steering is still functional in the event of any single-point failure. John Deere has gone to great lengths to help ensure the operator has the ability to steer the tractor if something goes wrong in the steering system.
 
For example, if the primary controller fails, a second controller takes over. If power from the alternator fails, the battery resumes control. If the engine quits running and is unable to supply hydraulic oil to the system, an electric-driven backup pump is used to supply the oil. There is a backup for ACS components.

The ACS system consists of several key components:

1. Gyroscope: this is used to measure the yaw rate (turn rate) of the tractor during transport speeds.
2. Road-wheel angle sensors: these sensors simply measure the steer angle of the tractor.
3. Power supply module: this module distributes the power of the battery and alternator throughout the ACS system.
4. Hand-wheel angle sensors and tactile feedback unit: this includes the steering wheel position sensors and a brake which can increase or decrease resistance dependent on speed. Lighter feedback is desired during normal field use, and slightly heavier feedback is desired during transport and while the tractor is cornering at high speeds.
5. Controllers: two controllers are located in the back of the tractor and are the brains of the system.
6. Control valves: also known as steering valves, control valves are used to steer the tractor.
7. Electric-drive backup pump: this pump supplies oil to the steering system, brakes, and park (for towing) brake if there is no longer a sufficient oil supply to the steering and brakes. 

Value of ACS

• Improves line holding when driving at transport speeds
• Fewer turns lock-to-lock: 3.5 turns lock-to-lock in the field for quicker headland turns and 5 turns lock-to-lock at transport speeds
• Eliminates hand wheel backlash and drift
• Reduces steering effort results in reduced operator fatigue
• Smaller hand-wheel diameter for improved operator comfort and visibility
• Maintains operator feel and touch-points of traditional steering column system
• Fully integrates with AutoTrac™ guidance assisted steering stems
• Compatible with suspended and non-suspended front axles
• Compatible with wide and narrow section width tires

The John Deere ILS utilizes industry-leading technology to supply unsurpassed gains to end-user productivity. This innovative design incorporates proven suspension design with mechanical front-wheel drive (MFWD) axle components that use state-of-the-art technology specifically for heavy equipment usage.

 

The ILS front axle is available on all 8R Series Tractor models.

The ILS system gets more power to the ground because the front tires maintain ground contact pressure. This improves field and transport ride plus increases ballasting flexibility and drastically decreases the tendency to power hop.

The ILS axle maintains minimum oil levels in the front differentials to assist in providing overall tractor operating efficiency.

 

John Deere ILS has three systems:

• A mechanical system
• A hydraulic system
• An electrical system

 

Mechanical system 

The mechanical system is further broken down into the mechanical drive system and mechanical suspension system.

The mechanical drive system includes:

• A three-position switch is included on a MFWD clutch.
• The MFWD clutch has six clutch discs and separator plates that can transfer as much as 40 percent of the tractor power through to the front ILS axle.
• The front differential transfers power from the engine to the individual right and left driveshaft through a ring and pinion.
• A hydraulically engaged front differential lock containing eight clutch discs and eight separator plates works in conjunction with the rear differential lock to assist the tractor in tough, wet conditions with increased power transfer to all wheels.
• A right and left constant-velocity telescoping driveline provides smooth power transfer to the outboard hubs.
• On 8245R, 8270R, 8295R, and 8320R Tractors, the ILS driveshaft speed is 6:1. On 8345R, 8370R, and 8400R Tractors, the ILS driveshaft ratio is 8:1. By using an 8:1 ratio on higher horsepower tractors, power can get to the wheels while minimizing the torque the U-joint experiences.

 

The mechanical suspension system consists of large cast, upper- and lower-control arms with cast steering knuckles for durability and reliability.

• There is a high steering capacity, even with dual wheels – 25 percent increase over model year 2013
• High torque in all steering positions provides maximum transfer of power to the wheels under all conditions
• Fully independent suspension maintains optimum ground contact at all times

 

Hydraulic system

The hydraulic system consists of suspension cylinders, a control valve manifold, a front differential lock, and hydraulic accumulators.

• There is a high steering capacity through large steering cylinders.
• Responsive link arms maintain contact with the ground surface, giving maximum tractive performance under any condition.
• Accumulators dampen energy from bumps to produce a smooth ride for maximum operator comfort.

 

Electrical system 

The electrical system contains position sensors, solenoids for the control valves, and a master controller for complete automatic control of the ILS system.

 

How does it work? 

The mechanical, hydraulic, and electrical systems work together to maintain a level and vertically-centered position of the front differential case in relation to the outboard hubs and planetaries, independent of tractor weight or dynamic loading. The system's ability to maintain a vertically centered position provides full suspension travel of 25.4 cm (10 in.). This translates to consistent soil contact for improved power to the ground as well as dampens the energy from bumps that cause a rough ride.

 

The tractor utilizes electronic and computer controls that monitor tractor functions and axle position. Based on those inputs, the electrical system automatically triggers hydraulic functions to raise, lower, or remain static.

 

The John Deere ILS uses a short/long A-arm design, which means the upper control arms are shorter than the lower control arms. During wheel movement, the upper control arm moves in a smaller arc than the lower control arm, and the difference in the two arcs creates a change in camber. The change in camber helps keep the inside and outside of the front tires perpendicular to the drive surface, a very important feature when optional front dual wheels are installed. This design provides anti-dive characteristics to naturally reduce the adverse effects of braking and acceleration.

 

The John Deere ILS front axle has been specifically designed to accommodate additional options, such as front 3-point hitches and front duals. To properly handle these options, large steering cylinders and knuckles provide up to twice the steering capacity of the standard MFWD beam axles so steering performance is maintained. A simple steering stop arrangement offers infinite adjustability for fine-tuning in any row spacing.

 

Braking system 

With higher speeds and expected heavy towed implements and carts, front brakes are optional on 42-km/h (26-mph) ILS-equipped tractors and part of base equipment on 50-km/h (31-mph) ILS-equipped tractors. The braking system is applied proportionally between the front and rear axle brakes to effectively stop the tractor. There are no operator adjustments or requirements to operate the additional braking system.

 

Tire compatibility

For travel speeds of 50 km/h (31 mph), B-speed-rated tires that provide high-speed capabilities are required.

With the ability to have a six-step drop from rear to front tire, the 8R equipped with an ILS axle is able to have group 49 rear tires with group 43 fronts. This allows for the benefits of group 49 tires while maintain the turning radius allowed by group 43 front tires.

NOTE: The use of group 44 tires for front duals does not allow for some row crop spacings.

Front duals

Front dual tires provide:

• Ultimate flotation and compaction management
• Increased load-carrying capacity
• Easy installation or removal; no need to remove the inner tire
• Bolt-on components versus studded flanges for superior flexibility for dual/no dual applications.
• Narrow hub extensions to ensure superior crop clearance for row crop applications
• A serviceability port has been added to eliminate the need to remove the front dual and hub in order to change the hub oil at the required service interval

 

Hitch application 

In hitch applications, it is important to maintain at least 50 percent of the ballasted front-axle weight (with implement raised) for steering control. Referring to the example below, the maximum ballasted weight of the front axle is 7756 kg (17,100 lb). If the tractor has a hitch-mounted implement, when the tractor is weighed with the hitch and implement fully raised, the front weight must be at least 3878 kg (8550 lb). The front axle capacity is directly proportional to the weight that can be carried on the hitch.

 

The MFWD axle has a front weight carrying capacity equal to the front tire carrying capacity. For example, in row-crop applications using the popular 480/70R34 (155 load index) front tires, the highest load rating is 3878 kg (8550 lb) per tire with a total of 7756 kg (17,100 lb) at maximum tire pressure. This means (depending on tire pressure and speed) there is as much as 3878 kg (8550 lb) available for support of rear implements in transport.

 

Maximum load carrying capacity of the axle is determined by the load carrying capacity of the tires and whether the tractor is equipped with singles or duals.

 

Additional ILS features: 

There is no on/off switch for ILS operation since the John Deere advanced electronic management system knows when to disengage ILS automatically. The electronic controller will activate a restricted mode of operation, when any of the following conditions are met:

• Both brake pedals are pushed
• The 3-point hitch raise/lower switch is activated
• The tractor is placed in park
• Wheel speed is less than 0.5 km/h (0.3 mph)
• Tractor is correcting for an out-of-level condition

Based on the inputs received (speed, suspension displacement, braking and operator input to hitch and/or remote cylinders), the tractor determines when the system should be active or inactive, making operation simple and efficient.

MFWD CommandARM™ controls for ILS

Shortcut keys on the CommandARM enable the operator to engage or disengage MFWD on the go, even under full load, without stopping or clutching. The switch can be placed in one of the following positions:

1. AUTO
2. On
3. Off (brake assist)

Mode 1 - AUTO

When this light-emitting diode (LED) light is lit, MFWD is on but automatically disengages when either of the following conditions are met:

• Either brake pedal is depressed and held to allow tighter turns
• Transporting at speeds above approximately 23.0 km/h (13.8 mph) to reduce tire wear; automatically engages when speed drops below 19.0 km/h (11.4 mph)
• When the front wheel turn angle meets an operator-defined point

As with the brake-assist position, when both brakes are depressed, the MFWD automatically engages (if not already on) to provide four-wheel braking.

Mode 2 - MFWD on

When this LED light is lit, MFWD engages continuously.

 
Mode 3 MFWD off (brake assist)

When no LED lights are lit, the MFWD is off. This is also referred to as the brake-assist position. Even though the MFWD is disengaged, when both brakes are pressed at speeds above 5 km/h (3 mph), the MFWD engages to assist braking the tractor.

Differential lock

The differential lock is another feature of the ILS axle. When the rear differential lock is engaged or disengaged, the front differential lock is also engaged or disengaged. This also includes a driveline shield.

If one wheel begins to slip, the differential lock can be engaged on the go and the axles are hydraulically locked together for maximum traction. There are two ways to engage the differential lock feature.

• Manual differential lock - differential lock can be engaged manually using a switch on the floor or by manually depressing a button on the CommandARM console. When brakes are depressed, the differential lock will disengage
• Automatic differential lock - when in auto mode, differential lock is engaged when the tractor is driving forward. Differential lock will disengage when front wheel turn angle meets disengage wheel angle setting defined by the operator via the CommandCenter or when either brake pedal is depressed. Differential lock will automatically engage when brakes are released or front wheels are turned straight.   

Additional equipment for use with ILS axle

• 3M front axle spacing kit:
  Front axle static weight for the ILS axle shall not exceed 6759 kg (14,900 lb) using the 3M kit
• H480 Front Loader
  Refer to the material handling section for additional information.

All 8R and 8RT Series Tractors come standard with an 85-cc displacement integrated hydraulic pump. This pump provides 227.1 L/min (60 gpm) of hydraulic flow.

 

A dual-pump option, featuring 85-cc and 35-cc displacement hydraulic pumps, is available for all 8R wheel models. The dual-pump system provides a hydraulic flow of 321 L/min (85 gpm), ideal for running at lower engine speeds.

 

SCV flow (approximate)
Engine rpm	Pump flow (85-cm3 pump) L/min (gpm)	High pump flow (85-cm3 pump + 35-cm3 optional pump) L/min (gpm)
800	86 (23)	122 (32)
1500	162 (43)	229 (61)
1700	184 (49)	260 (69)
1900	206 (54)	290 (77)
2100	227 (60)	321 (85)

 

Operating the tractor at reduced engine rpm contributes to a quieter cab, reduced fuel usage, and maintains the vacuum while turning and raising the planter on end rows. At 1500 erpm with a 321 L/min (85 gpm) system there will be an available flow of 229 L/min (61 gpm). This is an improvement over an available 162 L/min (43-gpm) flow when operating with a 227 L/min (60 gpm) system at 1500 erpm.

 

The maximum flow through one selective control valve (SCV) with a standard coupler is 132 L/min (35 gpm). A 19.1-mm (3/4-in.) high-flow coupler allows for a maximum flow rate out of one SCV of 153 L/min (40.5 gpm).

 

The hydraulic system is a closed-center, power-on-demand system using a load-sensing pressure-flow compensated axial piston pump with full-flow charge and flow prioritization for steering and brakes.

 

The pump outlet pressure available on demand can range from 3000 kPa (435 psi) for track models and 4000 kPa (580 psi) for wheel models at low standby to 20,400 kPa (2958 psi) at high standby.

 

Hydraulic pump options:

• 85-cc displacement, 227-L/min (60-gpm) hydraulic pump
  • NOTE: Standard on all 8R models.
• 85-cc and 35-cc dual pump option, 321-L/min (85-gpm)
  • NOTE: Compatible with 2014 Final Tier 4 (FT4) and newer 8R Wheel Tractors only.

The transmission control lever is placed on the left side of the CommandARM closest to the operator for convenient setting and adjustment.

Hydraulic and hitch controls

Hydraulic and hitch controls utilize fingertip paddle pots for raise/lower and extend/retract functions. An optional crossgate joystick replaces fingertip paddle pots for control of SCVs and allows for programmable hydraulic functionality according to operator preference. Rear hitch position can also be controlled with the encoder wheel located on the right side of the CommandARM. The encoder wheel allows for finite positioning of the rear 3-point hitch.

Three buttons near the encoder are for hitch set, lock, and return to height. Adjustment knobs for the 3-point hitch are located under the cover for the CommandARM control's storage compartment and allow for adjustment of the rate of drop, hitch height limit, and depth control.

 

Throttle

The throttle design incorporates buttons which control FieldCruise speed, foot pedal mode (if equipped), and transmission eco settings. 

 

Tractor function controls

Located just to the right of the throttle is the AutoTrac activation button and four sequence controls for iTEC functions. Behind the iTEC sequence controls, there are buttons which control the activation and deactivation of MFWD and differential lock.

Controls for radio, lights, rotary beacon (if equipped), hazard flashers, and HVAC system are located to the center-right on the CommandARM, along with PTO for both front (if equipped) and rear PTO.

The following functions can be adjusted using the CommandCenter display:

• Hydraulic settings
• Hitch settings
• Transmission settings
• FieldCruise
• iTEC programming functions
• Radio
• Lights

John Deere 8R Series Tractors are utilized in numerous applications that place different demands on tires. As such, multiple tire offerings are available for 8R Series Tractors to accommodate a wide range of grower needs. Tire options provide variability in terms of ground clearance, tread width, and floatation to match different operating conditions.

John Deere sources 8R Series Tractor tires from the following major brands:

• Mitas® tires
• Firestone® tires
• Goodyear® tires
• Michelin® tires
• Trelleborg® tires

Tire matching (rears and fronts)

Front and rear tires for 8R Series Tractors are sized and combined under different group sizes based on tire  rolling circumference. All front tire options for 8R Series Tractors are classified as group 42, 43, or 44, while all rear tires are classified as group 47, 48, or 49. The approximate overall diameters for each group are shown in the following table.

Group	Overall diameter
42	1498 mm (59 in.)
43	1600 mm (63 in.)
44	1676 mm (66 in.)
47	1955 mm (77 in.)
48	2057 mm (81 in.)
49	2172 mm (85.5 in.)

For tractors with mechanical front-wheel drive (MFWD) or Independent-Link Suspension (ILS™) front axles, there typically needs to be five steps (or group size difference) between the front and rear tires to maintain proper tire overspeed between axles. This means the group 42 front tire needs to be matched with group 47 rear tire, and group 43 front tire needs to be matched with group 48 rear tire. 

On 1500 MFWD axles, four-step combinations between front and rear tires are also acceptable (determined at the time of ordering the tractor). This means  group 44 front tire can be matched with  group 48 rear tire, or  group 43 front tire can be matched with  group 47 rear tire. Six step combinations are possible on tractors equipped with ILS, allowing group 43 front tires to be paired with group 49 rear tires in order to maintain narrower tread functionality with row crop width tire options.

Additionally, tires have a load index rating designed to report the load carrying capability of the tire.

Group 49 rear tires

John Deere 8R Series Tractors are now approved for group 49 rear tires. Group 49 tires have a larger diameter and longer footprint, which results in greater traction in most field conditions compared to smaller group size tires of the same section width and basic design. Group 49 tires also provide a larger air volume than comparable smaller group sizes, which can help control power hop in some conditions.

NOTE:

• Front tread spacing for group 49 tires (group 44 fronts) has to be 1930 mm (76 in.) or wider based on tire size. For 762-mm (30-in.) tread spacings, tractors equipped with ILS may be equipped with group 49 rear tires and group 43 front tires.
• 710/75R42 (group 49) tires are available in singles only (see Configurator for complete offering)
• 480/95R50 (group 49) tires are available in duals only (see Configurator for complete offering)
• Operators will experience a decrease in turning radius with group 49 tires due to the larger-diameter group 44 front tires.

John Deere’s ActiveSeat utilizes electrohydraulic technology in combination with air suspension, providing the operator with enhanced ride quality over standard air-suspension seats.

Operator movements are monitored in order to reduce vertical movement. An ActiveSeat suspension can isolate the operator from up to 90 percent of vertical movements typically seen in tractor applications.

The system uses a hydraulic cylinder that is connected to a control valve assembly. Electrohydraulic valves located in the control valve assembly automatically react to inputs from two sensors, a position sensor and an accelerometer. Inputs from these two sensors control oil flow from the tractor to the hydraulic cylinder to reduce the vertical movement of the operator.

The John Deere ActiveSeat has many of the same features of the ComfortCommand™ seat with the addition of a ride firmness switch. The ride firmness switch is located on the left-hand armrest and replaces the suspension shock-dampening seat attenuation lever on the front right-hand side of the ComfortCommand seat controls.
 
The ride firmness switch has three positions: plus, minus, and mid position. The three positions provide three different levels of seat performance:

• The plus position provides the greatest degree of ride firmness. This position allows more of the tractor's inputs to be felt by the operator (slightly rougher ride).
• The minus position provides the least degree of ride firmness, allowing minimal tractor inputs to reach the operator, resulting in maximum seat performance.
• The mid position allows a balance between the plus (+) and minus (-) settings.

The ActiveSeat is also available as a heated leather seat for increased comfort and easier cleaning. For tractor applications where operating speed is not limited by the implement, the ActiveSeat can allow for faster field speeds and increased overall comfort and productivity. 

 

NOTE: The John Deere ActiveSeat is not available on track tractors.

This kit allows any ISO-designed implement to transmit data to the tractor and back. It provides a controller area network (CAN) communication connection for front hitch ISOBUS implements.

The ISO cab implement controller area network (CAN) bus adapter is available to connect any ISO compliant implement or device to an 8R, 8RT, 9R, 9RT, 9RX (including Scraper Special) Series Tractor.  These connectors are commonly used for planter frame control boxes.

 

Refer to the operator's manual, sections 16 (CommandCenter™) and 25 (Operator Station), for additional information on ISO implements.

 

NOTE: If the harness is not in use, unplug it from the ISO 11783 location or plug the 4-pin connectors together on the harness.  If neither of these are done, implement CAN communication errors will occur.

The implement switch indicates to the CommandCenter™ when the implement is raised or lowered, to provide accurate data collection when using a performance monitor.

In today’s agricultural environment, accuracy and precision are more important than ever. For something as basic as ground speed, operators need key information for precise control of various implements and the tractor. To support these needs, tractors can be ordered with a dual-beam radar unit as a factory- or field-installed option.

 

There are several key features that have changed from previous designs.

 

First, there are two horns for exit of the radio beam. This dual-beam design assures a powerful and accurate signal that will cut through interference that at times makes single-beam units inaccurate. (See 1 in the image above for beam locations.) Dual-beam output makes radar less susceptible to hard surface or tall/wavy grass interference.

 

Accuracy is aided by a heavy-gauge mounting bracket and rubber isolators that reduce chances that vibration can affect the radio signal.

 

Dual-beam radar has a fast update rate. When the tractor comes to a stop, accelerates, or varies speed, the indicated ground speed on the tractor display will closely match the actual ground speed. This is important for implements that use radar speed to control operation such as planters, seeders, fertilizer applicators, and sprayers.

In addition, the dual-beam radar does not require calibration to assure accuracy. Its self-calibrating ability is sure to save setup time by elimination of a special procedure that was required in the past.

 

The radar true ground speed sensor activates the following CommandCenter^TM display or performance monitor readouts:

• Percent slip
• Hitch slip command (if equipped)

Radar usage improves the accuracy of the following CommandCenter or performance monitor functions:

• Area covered
• Area/hour
• Distance and ground speed

Dual-beam units are compatible with controller area network (CAN) bus and International Organization for Standardization (ISO) bus electrical systems.

This alarm sounds an audible warning when the tractor is in reverse gear to warn bystanders of potential rearward movement of the tractor and any connected implements.

IPM

NOTE: IPM is only available for Tier 3/Stage IIIA, Interim Tier 4/Stage IIIB, Final Tier 4/Stage IV engines, and not for Stage II engines.

 

This feature is for many typical farming operations that use the rear power take-off (PTO) in high-power applications or the tractor as a transport vehicle. Operators who are looking for more power in non-stationary PTO and transport applications will be interested in the IPM feature.

 

In high rear PTO power applications such as forage harvesters, rototillers, and beet or potato harvesting equipment or where heavy trailers, carts, or implements are moved to and from various locations, this feature provides significant additional capabilities. The solution improves productivity with more consistent ground speeds, quicker acceleration, and the ability to better hold desired transport speeds.

 

This two-in-one tractor solution successfully operates in power-intensive PTO and transport applications at reasonable low fuel consumption without being disadvantaged by the higher weight, the bigger proportions, and the extra costs of the next higher horsepower model.

 

This feature is available as a factory- or field-installed option.

Tractor applications

Rear PTO field applications

• Rear-mounted snow blowers
• Sugar beet harvesting
• Forage harvesters
• Potato harvesting
• Rotary cutters
• Mower conditioners
• Flail mowers
• Balers
• Soil stabilizing
• Power harrow
• Vegetable bed formers
• Muck spreaders

 

Transport applications

• Grain carts or wagons
• Slurry tanks
• Implement transport from field to field
• Pull-type sprayers
• Extensive operation in hills/roadways

 

This is not intended to be an inclusive list of all applications but shows the wide range of uses for additional engine horsepower.

Power available

IPM provides engine power increase in levels proportional to the size of the tractor. IPM provides a controlled power boost of up to 26 kW (35 engine hp) to tractor under the following operating conditions:

• Tractor moving and PTO under load
• Transport during acceleration
• Transport during deceleration

Power increase is not provided under draft applications or non-loaded rear PTO applications. Power increase is only provided when required.

How it works

There are specific operating parameters when IPM functions to boost engine power. It is the "intelligent" part of the system that provides seamless operation while adjusting the engine horsepower depending on how the tractor is being used.  For engine horsepower boost activation, the tractor must already be running an application that is using the full power capability of the tractor.

 

PTO activation

Power must be sensed going through the PTO drive clutch by the tractor's electronic systems. The tractor must be moving at least 0.5 km/h (0.3 mph) and PTO consuming moderate power before power boost engages. The speeds shown above, assume lowest possible gear or speed setting and the engine running at 2100 rpm.

 

NOTE:  If the tractor is equipped with a front PTO, additional IPM power will transfer through the front PTO.  However, IPM activation is only sensed through the rear PTO. Adequate load must be sensed on the rear PTO in order for IPM to activate.

Transport activation

 

When in transport applications, power transition is smooth. The engine will respond seamlessly as load changes, such as when going up and down hills. Additional power is available at a useful working speed with minor differences between tractor models and transmissions.

 

The minimum ground speed is where additional power will begin to be applied, assuming the engine is already fully loaded. Ramp up to full additional power occurs as speed continues to increase. Full additional power occurs within a 3 mph (5 km/h) band.

 

Transport during acceleration: power boost occurs in steps through the range from 23 km/h – 28 km/h (14.3 mph – 17.4 mph).

Transport during deceleration: power boost ramps down in equal steps in the range from 23 km/h – 18 km/h (14.3 mph – 11.2 mph).

Power boost levels other than at rated rpm

Some operators will run the tractor at full loads and/or run transmissions in auto mode in transport. This means that the engine most likely will not be operating at rated rpm. As the engine is loaded, it will eventually drop off of rated rpm and use the power bulge as rpm slows. This is the way every John Deere PowerTech™ Plus engine operates when it is loaded to maximum power and torque.

IPM (shown in purple in chart above versus standard power shown in blue) provides additional engine horsepower from rated engine speed down to approximately 1600 rpm (shown on the x-axis in image above, with power kilowatt shown in the y-axis), which is peak engine torque.

 

Horsepower levels are increased above base equipment power bulge values.

 

If the PTO is engaged and the engine rpm stays near rated speed of 2100 rpm, the full additional power potential for the tractor model will be available for use to handle additional load from the implement or changing terrain.

 

If the PTO is not in use and in transport operation, and the rpm has dropped off of rated speed, usable additional power boost of IPM will taper off as rpm decreases. The chart above (with 8345R Tractor power curves) shows the relationship of how much additional usable horsepower is available in the operating range. All tractors operate in a similar manner with this feature.

Operator visibility and control of operation

 

All tractors have the power meter display function as base equipment. The operator can observe when full capabilities of the tractor are being utilized. This function graphically displays power utilization up to rated horsepower and power bulge.

 

The power meter can be found in the CommandCenter™ display. If the engine is off or has minimal load, the power meter will not fill in. The meter is similar in concept to a cellular phone's signal-strength meter. As the power increases, it will fill in bars in an icon. The display will also show the level of additional power being used. The long section represents up to the rated power. The smaller section represents power bulge and is an indicator of additional power available with IPM.

 

Via the CommandCenter, there is also the ability to enable or disable the function. The operator's manual provides simple details about navigating the engine screen.

 

IPM is automatically enabled each time the tractor is started.

Tractor compatibility with additional power

IPM has been thoroughly tested by John Deere engineers to be compatible with the base tractor equipment with no impact to reliability. John Deere provides IPM as opposed to unapproved aftermarket devices that boost power without regard to engine, transmission, axles, and drawbar, or hitch capability.

 

This feature provides optimal utilization of tractor components. For example, with PTO operation, power goes through axles to move the tractor along the ground and turn the PTO shaft and implement. Adding power to both of these systems does not overload either one individually. At transport speeds, drive train torque load decreases significantly from levels seen at low field speeds. Adding power at transport does not overload transmissions or axles.

 

Aftermarket devices are not selective when power increases are available. Great amounts of power increase are promised with these devices. Large power changes are not compatible with base tractor equipment. To note, base tractor equipment changes as power increases. Larger parts, like hitches, drawbars, tire size, drive train components, axle diameters, and engine calibrations for emission performance and cooling, ensure durability of the total vehicle as power increases. Operating outside of the design capabilities of the tractor base equipment will have an impact on durability and reliability.

 

 

Rear fenders are designed to provide optimum mud control by increasing the coverage of the rear tires in all directions. Two rear fender extension options are offered to provide overall width coverage of 2.55 m (100 in.) or 2.75 m (108 in.).

Most importantly, the fender increases the coverage over the rear of the tire, decreasing the amount of mud or debris buildup on the cab's windows, selective control valve (SCV) stack, hitch, and drawbar.

Rear fenders are available as factory-installed or as a field-installed attachment.

Front fenders help protect the cab glass and other areas behind the front wheels from paint damage and filth. Recommended for use with Group 44 tires, 600 mm (23.6 in.) or wider.

To fulfill the legal requirements of some areas, a front tow point can be field installed on the front base weight. Mounting hardware must be ordered individually.

Front weights provide additional ballast for the front axle.

Cast Quik-Tatch suitcase weights (R127764) can be added to provide additional ballast for implements that exert heavy draft loads and require additional ballast or with hitch-mounted implements that require additional ballast to maintain steering control while transporting.

 

These weights are Quik-Tatch weights that require minimal effort to attach.

Pick-up weights

Pick-up weights are design to add fast weight to the tractor. Following pick-up weights can be mounted at the front.

 

Support (base weight):

• Pick-up weight 900 kg
• Pick-up weight 1150 kg

All pick-up hitches can be mounted also at the rear in the 3-point hitch as a counter weight.

To use the third mounting point, an additional center-link bracket is available.

 

 

1500 kg and 1800 kg  pick-up weights

 

The two weights differ only internally, therefore no external differences are visible.

 

The pick-up weights can either be installed on the rear hitch or on the front hitch of the tractor using the center-link bracket. They cannot be mounted directly on the front base weight. A front hitch is required. The center-link bracket for installation is included.

The new shape of the 1500 kg and 1800 kg pick-up weights allows a quick and safe mounting.
This is ensured by an optimal alignment of the weight and the tractor along with a self-centering design.
Major benefits of the new design:

• Easy and comfortable
• Less time is required
• Lower risk of injury

Due to the user-friendliness, an optimal ballasting of the tractor is guaranteed at any time.
The performance of the tractor is used to a greater extent, which leads to higher productivity and a reduction in fuel consumption.

The weights cannot be front installed in combination with Quik-Tatch front weights.

 

NOTE: Ballast should be limited by the lowest of either tire capacity or tractor capacity. The carrying capacity of each tire should not be exceeded. For more ballasting information refer to the operator's manual and ballast calculator.

The auxiliary reservoir kit for the model year 2014 and newer 8R Series Wheel Tractors holds 50 L (13.2 gal.) of oil, providing a total hydraulic oil capacity of 90 L (23.8 gal.). This additional volume helps ensure that the tractor has enough hydraulic oil for applications using large single-acting cylinders or needing large hydraulic oil flow in a short period of time.

The reservoir is available as a factory- and field-installed kit to meet the needs of specific applications and is not needed for ordinary hydraulic operations.

This kit provides adjustable flow rates, breakaway couplers, and is iTEC™ control capable.

It is required for front implements needing additional hydraulic functions.

It requires software (R551978) to be ordered. Please check corresponding installation instructions for more details.

The field-installed electronic SCV kits are made available for tractors needing additional SCVs. These kits provide metered flow rates and timed detents with pressure and load sense compensation. The additional SCV(s) can also be integrated into the Headland Management System.

The field-installed kit includes International Organization for Standardization (ISO) lever-assisted breakaway couplers and armrest control lever.

To assist hooking up large equipment where multiple connections are required, factory-installed auxiliary hydraulic couplers are available.

Auxiliary sump coupler

The sump coupler kit allows oil to return from the hydraulics motor at low pressures. This coupler is required for correct attachment to current-production seeding products with case drain lines. The connector in the sump port is not to be used to carry return flow from a function to the tractor.

This coupler is required for correct attachment to current-production seeding products with case drain lines.

Hydraulic motor return couplers

The hydraulic motor return couplers can be used as couplers for return oil flow, from hydraulic orbital motors and other devices to the tractor's low-pressure return port, labeled R on the tractor.

 

Use of this connector specifically in the return to sump port position is for hydraulic components that require a leak-off line connection to the tractor. Components and implements that require this typically are larger orbital motors that require a drain for seal protection. The connector in the sump port is not to be used to carry return flow from a function to the tractor.

Power beyond couplers

Power beyond provides live hydraulic power to equipment. This kit supplies oil pressure to implements when the engine is running.

 

Any implement using power beyond must have a way to control oil flow. Use an independent control valve that is pressure-and-flow compensating (supplied separately) to control the oil flow rate from this coupler set. Power-beyond functions require a load-sense signal to regulate pump pressure, therefore, a load-sense hydraulic line is used. Certain equipment may require modification.

The auxiliary hydraulic optional equipment includes the following:

A – Pressure coupler
B – Load sense coupler
C – Return coupler (motor return)

This oil line provides low pressure return for front hitch implements. It is recommended for hydraulic motor applications to provide a free oil return to the tractor's low-pressure return port.

Lift assist wheels are often used with heavy 3-point-hitch-mounted implements. The hitch auxiliary raise kit provides hydraulic power for use with the lift assist wheels. Turning and transport are made easier using this feature.

For installing tractor case drain for vacuum motors. A motor seal drain kit (return to sump) protects the motor and shaft seal by allowing motor housing pressure to return back to hydraulic reservoir free of any back pressure. Handles up to 3 U.S. gallons per minute.

 

NOTE: All vacuum planters built after 1 May 2004 have hydraulic case drain vacuum motors. These motors have a flush-face case drain hose tip on the return oil line that must be routed to the tractor's sump/case drain port. The tractor requires a case drain coupler be installed in this port to accept the return hose. 

 

This kit is required for operation of 1910 Commodity Air Cart and 1990 CCS^TM hydraulically-driven fan.

The field-installed kit provides easy installation and operation of equipment using power beyond. After installing this kit, you will be able to manually adjust the standby pressure of the tractor to the application and electronically turn the load sense signal on or off from the cab.

Always turn the load sense signal off when starting the tractor. Turning the load sense signal off will keep the pump at low standby pressure while cranking the tractor.

As a further benefit, when the power-beyond application is not needed, the valve can be turned off, reducing power needed to operate the hydraulic pump and lowering fuel consumption.

Xenon HID lights improve nighttime visibility

John Deere has taken advantage of advanced lighting technology. This lighting provides the operator with industry-leading performance in nighttime visibility.

The important part of the system is the use of Xenon high-intensity discharge (HID) bulbs. These bulbs provide extreme brightness and a daylight color output for excellent definition of the field. The performance of this system allows the operator to easily view as much as 250 percent farther ahead, compared to previous tractors. A further benefit is there are no filaments in the HID bulb. Bulb life is increased by as much as 10 times vs. filament-style bulbs.

Front FieldVision lighting

The front lighting package adds three high-intensity discharge (HID) lights to the front grille (see 1 in the image above). To further enhance all-around tractor lighting, there are two additional 65-W halogen work lights added to the left- and right-hand cab roof.

 

The center of the bulb has a semi-spot lens, and the outer light housings have a flood lens. In row-crop, the operator will notice there is a longer beam of light in the center for following marker furrows. The overall width of the lighting pattern for a non-row-crop operation will be obvious so tilled or seeded passes are easily identified. The inner, larger-diameter light assemblies are used for road transport and use conventional halogen 60-/55-W H4 bulbs. These larger light housings are also used in the base lighting system. With the dual-wattage H4 bulb, the operator will notice that there is a true automotive-style high/low function when operating in the road position.

 

The cab roof lights can be adjusted to aim to the side or rear of the tractor.

Rear FieldVision lighting

The premium HID lighting package (code 1720) adds two adjustable-position HID lights on the rear fenders.

 

Unlike aftermarket lights where the operating ballast is integral, these lights use a smaller housing with remote-mounted ballast.  The smaller housing decreases obstruction for a clear view looking out the rear window.  Using the light’s wide-angle flood lens will make it much easier to monitor the widest or longest equipment available.

Nighttime visibility can be improved on tractors with two roof-mounted front floodlights or two roof-mounted side floodlights.

For additional transport visibility, install a rotary beacon light.

Option code 9779 on the 7030 Series Large-Frame Tractors includes the rotary beacon light. The light features a fully-adjustable, double-clamp design that provides a more rigid vertical support stem.

 

Rotary beacon lights can be installed for additional transport visibility and commercial or governmental applications. The rotating, high-intensity light rests securely within an amber-colored lens.

Eliminate the need for replacing bulbs with this pedestal-mounted LED light. The light is more like natural sunlight compared to traditional incandescent technology. The included connector harness makes this lighting upgrade a true plug-and-play solution for a quick and simple installation. The kit includes all necessary materials (including hardware) for one single light upgrade/replacement. For upgrading/replacing both rear fender lights, order two kits.

Custom key door locks

Field-installed kit (AL71345) allows for a door handle to be installed that has a key different from the tractor ignition key.

Front weights provide additional ballast for the front axle.

Cast Quik-Tatch suitcase weights (R127764) can be added to provide additional ballast for implements that exert heavy draft loads and require additional ballast or with hitch-mounted implements that require additional ballast to maintain steering control while transporting.

 

These weights are Quik-Tatch weights that require minimal effort to attach.

Pick-up weights

Pick-up weights are design to add fast weight to the tractor. Following pick-up weights can be mounted at the front.

 

Support (base weight):

• Pick-up weight 900 kg
• Pick-up weight 1150 kg

All pick-up hitches can be mounted also at the rear in the 3-point hitch as a counter weight.

To use the third mounting point, an additional center-link bracket is available.

 

 

1500 kg and 1800 kg  pick-up weights

 

The two weights differ only internally, therefore no external differences are visible.

 

The pick-up weights can either be installed on the rear hitch or on the front hitch of the tractor using the center-link bracket. They cannot be mounted directly on the front base weight. A front hitch is required. The center-link bracket for installation is included.

The new shape of the 1500 kg and 1800 kg pick-up weights allows a quick and safe mounting.
This is ensured by an optimal alignment of the weight and the tractor along with a self-centering design.
Major benefits of the new design:

• Easy and comfortable
• Less time is required
• Lower risk of injury

Due to the user-friendliness, an optimal ballasting of the tractor is guaranteed at any time.
The performance of the tractor is used to a greater extent, which leads to higher productivity and a reduction in fuel consumption.

The weights cannot be front installed in combination with Quik-Tatch front weights.

 

NOTE: Ballast should be limited by the lowest of either tire capacity or tractor capacity. The carrying capacity of each tire should not be exceeded. For more ballasting information refer to the operator's manual and ballast calculator.

Power strip and accessories

The power strip provides six additional electrical outlets that give either permanent or ignition-key-controlled power for such items as:

• Computers
• Portable telephone chargers
• Implement monitor
• Implement supply
• 12-V and up to 30-amp total current can be taken from these outlets

 

The power strip is not a surge suppressor. Electrical equipment with program memory or capacity for data storage requires protection from the damage of electrical surges and spikes that could occur in systems without transient voltage protection.

Intelligent Power Management (IPM)

IPM is compatible with 7R and 8R Series Tractors equipped with a front PTO option. The front PTO, rear PTO, or transport speeds can activate IPM on 7R Tractors. However, on 8R Tractors, IPM is only activated by the rear PTO or by transport speeds. For example:

• A front snow blower will not benefit from IPM on an 8R since the front PTO alone will not activate IPM.
• A triple-mounted mower-conditioner will benefit from IPM as high power levels are transmitted via the rear PTO. The front mower-conditioner will have 150 hp available to it on an 8R, which is adequate to operate these mowers in most crop conditions.
• See Intelligent Power Management for more information

PTO disconnect on 7R Series Tractors

Disconnecting the PTO drive to the PTO box when not in use increases tractor efficiency by reducing:

• Power requirements, which saves nearly 70 percent of power required to run the PTO disengaged
• Wear on components of the PTO box; components are not moving when the PTO is disconnected

Refer to the operator’s manual for instructions on how to disconnect the PTO when not in operation.

Front PTO operation

Front PTO engagement is actuated through an engagement switch similar to the rear PTO located on the CommandARM™ controls.

• PTO clutch is electronically activated with automatic torque modulation.
  • PTO modulation is selectable through the CommandCenter™ console and display.
• To activate the PTO remotely, select the remote PTO enable button in Generation 4 CommandCenter display, push down and forward on the FPTO switch in the cab and use the remote control at the front of the tractor.

NOTE: For the 8R Series, if the tractor is equipped with a front PTO, additional IPM power will transfer through the front PTO. However, IPM activation is only sensed through the rear PTO. Adequate load must be sensed on the rear PTO in order for IPM to activate.

The 70-kg (154-lb) starter weight is required for installation, and provides guide lugs for improved installation and removal of the 900-kg (1984-lb) weight. 900-kg (1984-lb) weight ballast option is compatible with steel, dual wheels with rim diameters of 106.7, 116.8 cm, or 127 cm (42 in., 46 in., 50 in., or 54 in.). This allows the weights to be added to only the outer rear dual on a rack-and-pinion axle and double-flat axle with single-taper hub.

 

NOTE: This weight option is not compatible with 96.5-cm or 137.2-cm (38-in. or 54-in.) wheels.

 

For operators requiring additional ballast or additional traction on the rear axle

72-kg (159-lb), 205-kg (452-lb), 625-kg (1378-lb), and 970-kg (2138-lb) cast rear-wheel weights are available for the 7R and 8R Series Tractors. The attaching hardware for all rear-wheel weight options may be ordered through parts.

 

The range of rear-wheel weights can provide the proper amount of rear axle ballast for a variety of applications. The addition of this ballast will increase traction on the rear axle of the tractor. These weights can also be used to counterbalance the effect of adding additional weight on the front axle in the form of a front weight support, front hitch, front spray tanks, and front-end loaders.

 

72-kg (159-lb) starter weight

The 72-kg (159-lb) cast rear-wheel weight is offered individually as attachment R167153. This weight can be used either as an inner or outer rear-wheel weight. The 72-kg (159-lb) weight can be used by itself or as a starter weight for the 205-kg (452-lb) rear-wheel weights.

 

205-kg (452-lb) weight

The 205-kg (452-lb) cast rear-wheel weight is offered individually as attachment R07782. The 72-kg (159-lb) starter weight (R167153) must be installed prior to the 205-kg (452-lb) weight on rear steel wheels. This practice is optional on cast wheels; however, most weight packages will be configured this way.

 

625-kg (1378-lb) weight

R553540 includes one 625-kg (1378-lb) cast inner rear-wheel weight. This weight is to be used on the inside of the rear wheel assembly. This option can be stacked on a double-flat cast hub, with a 70-kg (154-lb) starter ring on the outside.

 

70-kg (154-lb) weight 

BRE10026 features a 70-kg (154-lb) starter weight. The starter weight and guide lugs provide improved installation and removal of the 900-kg (1984-lb) weight. This weight can be used individually on the outside of the steel, dual rims on rack-and-pinion axles, or on the outside of the double-flat, single-taper wheel hub. For the approved cast hubs, can also be used with the inner cast weights as well.

 

NOTE: Use on the outer side of approved cast hubs will limit dual tire and spacing capability.

Front dual wheel extensions allows the ability to run front dual wheels (four tires on the front axle) at fixed spacing ideal for row crop applications using the 1500 or Independent-Link Suspension (ILS™) front axle (group 47-49 tires). Never install front duals on a 1300 mechanical front-wheel drive (MFWD) axle.

 

When either of these kits are installed, the front wheel base (outer to outer wheel) grows to 289.6 cm (114 in.), leaving both the front right and left wheel sets on 76.2-cm (30-in.) centers.

 

Refer to the operator’s manual: Front wheels, tires, and treads section and reference the stories on installing dual hub extensions. Installation instructions from the online library may also be used for reference.
