9420RX Tractor

The John Deere exhaust filter is integrated into the engine design and electronics to provide a seamless operator experience. The engine control unit (ECU) and exhaust temperature management (ETM) system work together to continuously regenerate the exhaust filter using a natural cleaning process sometimes referred to as passive regeneration.

 

If natural filter cleaning cannot be achieved based on temperature, load, and speed, then particulate matter (PM) must be removed using an automatic cleaning process sometimes referred to as active regeneration. In most cases, filter cleaning does not impact machine operation or require operator involvement. Higher pressures created by our Final Tier 4 (FT4)/Stage IV high-pressure fuel system extend intervals between automatic cleanings.

How EGR works

EGR reduces the high temperatures where nitrogen oxide (NOx) compounds are formed in the engine cylinders by replacing excess oxygen with a prescribed amount of cooled exhaust gas.

 

Exhaust gases contain more carbon dioxide than oxygen. The EGR valve, in conjunction with the venturi and ECU, allows a controlled amount of exhaust gas to enter the intake manifold to mix with the incoming fresh air. Replacing excess oxygen with cooled exhaust gas leads to lower combustion temperatures, creating less NOx. In addition, EGR allows for advanced timing, leading to optimal performance of the engine, maximizing fuel economy.

 

Flow of exhaust during engine operation

Exhaust airflow enters into the EGR cooler from the exhaust manifold near the turbocharger.

 

Based on engine load, air temperatures, and rpm, the ECU opens or closes the EGR valve, allowing a measured percentage of exhaust gas to enter the intake manifold.

 

The gases mix with the rest of the incoming air from the turbocharger and aftercooler before entering the cylinders.

 

The following diagrams illustrate how air flows through the engine (PSS).

 

For added performance and efficiency, the engine passes the exhaust gases through an EGR cooler before it enters the engine.

The user can view exactly what the operator sees on the GreenStar™ 3 2630 Display and Generation 4 CommandCenter from almost any internet-connected device. RDA is available on the 4600 and 4100 CommandCenter and allows for an increase in productivity with quicker problem resolution. By using RDA, the cost of operation will decrease due to reduced labor and travel costs, and maximum efficiency will increase profit.

Seat swivel

The design of the CommandARM allows for up to 40 degrees of right-hand seat swivel.

The e18 transmission delivers smooth shifting and intuitive controls in a reliable 18-speed PowerShift transmission. The e18 transmission with enhanced Efficiency Manager is standard equipment on all 9 Family Tractors.

The e18 has evolved from more than 50 years of John Deere PowerShift technology. With more automatic features, the e18 is easy to operate for all levels of operators and operations. It features three modes of operation, full AUTO, custom, and manual modes. Full AUTO and custom modes manage the engine and transmission to match the desired ground speed to the field conditions. These two modes are ideal for most conditions and take the guess work out of operation. Manual mode is perfect for operators looking to operate the e18 like a traditional PowerShift by bump shifting and managing the engine throttle to their liking.

As the next generation of PowerShift technology, the e18 delivers the strength to handle sudden, high-torque power loads while maintaining responsive, quick, and smooth shifts.

e18 controls

CommandCenter™ controls

The CommandCenter is the central information system for tractors and allows the operator to program various settings tailored to a specific operation.

To access the tractor’s transmission settings, press the transmission shortcut button on the CommandCenter shortcut bar.

Operating modes

The e18 application settings employ three modes to take full advantage of the engine-transmission communication: Full AUTO mode, custom mode, and manual mode.

Full AUTO mode

Full AUTO mode manages the tractor’s engine and transmission inputs to reach and maintain the desired ground speed set by the operator. This means the tractor will manage shifts and engine rpm to operate at the most efficient level possible. Operators have the ability to set the maximum forward and reverse speeds for their particular applications. In full AUTO mode the operator can adjust the desired ground speed in two ways, by conducting a traditional bump shift or by rotating the dial on the thumb wheel.

When shifting in full AUTO mode, the transmission shifts set speeds and does not always shift gears, meaning the transmission may not necessarily shift gears if it can reach the desired ground speed with a slightly higher or lower engine rpm. Efficiency Manager is automatically engaged while operating in full AUTO mode. As a result, shifting will not take the tractor out of Efficiency Manager in full AUTO mode.

Custom mode

Custom mode operates similar to full AUTO mode but allows operators to adjust operating parameters to meet a specific operation. It also has the ability to activate eco mode for a higher level of operation.

Eco allows two minimum engine speeds to be set. Operators can turn eco on and off by either pushing the eco button on the side of the throttle or by selecting eco in the transmission settings page of the CommandCenter controls. For example, operators may choose to turn eco on during transport to utilize a lower minimum engine speed and then turn eco off while operating in the field where a higher minimum engine speed is desired.

Efficiency Manager

Efficiency Manager is automatically enabled in auto and custom modes. Efficiency Manager can be turned on in manual mode by selecting the set speed one or set speed two button on the CommandARM™ console. The set speed adjuster on the top of the single-lever gear selector allows the operator to dial in the desired ground speed to establish set speed one or two. Once engaged, Efficiency Manager will manage the engine rpm and gear selection to maintain the desired working speed. To reach the desired set speed, the throttle must be set to full engine rpm.

In the advanced settings page, operators can customize the auto shift engine speed droop as a percentage of the full engine speed. In addition, the load anticipation feature can be enabled for the hitch engagement, hydraulic engagement, or both.

Manual mode
Manual mode operates very similarly to a traditional PowerShift transmission with Efficiency Manager.
In manual mode the operator manages the engine and transmission inputs by controlling the shift lever and hand throttle.

e18 operation

Setting start-up gears

The 9 Family Tractors default to 7F and 2R at start up. However, these default start-up gears can be adjusted from 1-13F and 1-3R through the CommandCenter. Refer to the operator’s manual for additional information.

Dual hydraulic pump system

Optional high-flow hydraulics are available on 9 Family Tractors by ordering code 3270. The high-flow hydraulic system provides an additional 215 L/min (57 gpm) of flow for a total of 435 L/min (115 gpm). This system is ideal for hydraulic fan motor demands. This system is recommended for agricultural implements with continuous flow requirements. When maximum hydraulic pump capacity is reached, multiple functions will continue to operate at the same proportional flow rate.

The 9 Family Ag High-Flow Tractors have two parallel hydraulic systems. The benefit of this system is that functions can be split between the two systems. Functions that require high flow and low pressure can be combined on one system (for example, air seeder fans, and planter motors). Functions that require high pressure and low-flow can be connected to the remaining system (for example, implement lift, fold, and constant down-pressure systems).

Following these guidelines allows the hydraulic system to run cooler as it prevents both hydraulic pumps from running at high pressure. In general, pumps forced to run at both high pressure and high flows generate much more heat than a pump running at a lower flow or lower pressure.

The system operates with two hydraulic pumps:

• Pump 1 - provides hydraulic flow of up to 215 L/min (58 gpm) to SCVs 1, 2, and 3. These SCVs are useful for operating lift/lower and other cylinder type hydraulic needs.
• Pump 2 - attaches in front of pump 1 and provides hydraulic flow of up to 215 L/min (57 gpm) to SCVs 4, 5, and 6. These SCVs are useful for operating hydraulic motors to drive air/fan or vacuum systems on seeding/planting equipment.
• All SCV oil returns to one common hydraulic reservoir.

Eight-section SCV stack for high-flow requirements

For applications requiring continuous high hydraulic flow or multiple 1.9-cm (3/4-in.) hydraulic connections, this SCV stack is designed to maximize efficiency of the hydraulic system while providing additional flow using 1.9-cm (3/4-in.) couplers. Arrangement of the 1.9-cm (3/4-in.) couplers are split between the tractor’s dual hydraulic pumps to even the hydraulic load on each pump. Increasing coupler size from 1.3 cm (1/2 in.) to 1.9 cm (3/4 in.) allows an additional 26.5 L/min (7 gpm) or 17 percent more hydraulic flow through each coupler and reduces backpressure for hydraulic functions such as dual fan motors associated with the Air Power™ 2 system equipped on John Deere C850 Air Carts. With three 1.9-cm (3/4-in.) couplers available, operators can connect to other high-demand functions such as raise/lower. The 1.9-cm (3/4-in.) couplers also allow higher fan motor speeds for high-rate applications and allow more power to the ground due to less restriction on the hydraulic system.

 

NOTE: This SCV configuration is available on all double-reduction) axle 9420R to 9570R Tractors with high-flow hydraulics and all 9RX Tractors with high-flow hydraulics. This eight-section SCV stack does not include hydraulic Intelligent Power Management (IPM) software.

Connections to 1.3-cm (1/2-in.) and 1.9-cm (3/4-in.) couplers are quick and simple for operators with a split SCV stack configuration at a comfortable connection height.

Regular service and maintenance are essential to the performance, productivity, and longevity of all farm machinery.
 
Maximum uptime is an important element of productivity.

• 9 Family service points are quick and simple to check.
• Greater accessibility improves serviceability.

All items in the daily service schedule can be performed without the use of tools:

• Engine oil, hydraulic oil, coolant level, and water separator can be conveniently accessed from ground level without having to open the hood. Engine oil can be checked by simply removing one small engine side panel.

• Engine can be easily accessed by simply raising the one-piece hood and removing two engine side panels for more periodic maintenance checks.
• Single-point latch mechanism ensures easy hood opening and closure.

 

NOTE:  Always refer to the operator’s manual for complete maintenance and service recommendations.

Refueling

The 9R Series Tractors fuel tank is located over the rear axle. The fuel tank features a dual fill design. This design allows the machine to be filled from either side of the fuel tank. A fuel nozzle holder is located when the operator positions themselves on the gudgeon platform to fill the fuel tank.

 

The diesel exhaust fluid (DEF) tank is located on the left-hand side of the tractor indicated by a blue cap. It is fillable from ground level and has a protective shield to keep debris out of the fill neck.

NOTE:

• John Deere supports the usage of bio diesel. Bio diesel should meet ASTM D6751 (US) or EN 14214 (European) fuel quality standards.
• Tractors receive fuel containing a 2 percent bio-diesel blend at the factory.
• Acceptable blend levels may vary by geographic region.
• Diesel exhaust fluid will freeze when exposed for longer than three hours to conditions below -11°C (12.2° F).

For more information about the use of bio-diesel in John Deere engines, refer to www.JohnDeere.com/biodiesel.

 

Severe-duty water separator, if equipped

The severe-duty water separator can extend service intervals and helps to protect the tractor’s fuel system from damage associated with lower-quality fuel.

Simply open the drain valve on the bottom of the separator and drain accumulated water.

NOTE: Cummins® QSX 15 L (915.4-cu in.) engines cannot be equipped with a severe-duty water separator; however, the fuel filter has separating capabilities like the primary filter on John Deere Power System engines.

Primary air filter access

On the 9R and 9RX, the primary engine air filter is accessible from the left-hand platform for replacement annually or as operating conditions require. The filter is aspirated and extends filter life in dusty conditions by aspirating more than 95 percent of incoming dust. Aspirator suction is created by utilizing the air flow from the cooling fan.

 

On the 9RT, the primary engine air filter is located at ground level on right side of tractor.

Battery access

The 9R and 9RX battery location is behind the left-hand step assembly. There are three bolts that secure the swinging step assembly that need to be removed to completely access the batteries. The 9RT top step of the platform conceals the tractor’s three 12-V batteries with 2775 CCA (925-CCA each). Tractors with the Cummins X15 engine will have four 12-V batteries in the same location as tractors equipped with John Deere Power System engines.

Although the batteries are maintenance free, conditions such as long periods of operation at high ambient temperatures and excessive engine cranking may require adding water.

Battery boost terminal

On the 9R and 9RX, a battery boost terminal is located on the left-hand side of the engine for convenient and proper boost assisted starting.

Windshield washer

The windshield washer bottle is optional on 9R and 9RX Tractors and is located on the left side of the tractor near the DEF fill point. On 9RT Tractors, it is located on the right-side frame.

Maintenance-free U-joint

Maintenance-free U-joint bearings require no servicing to reduce maintenance time.

Transmission, hydraulic, and axle oil level

A sight glass for the transmission, hydraulic, and axle oil level is located at the back right side of the gudgeon, indicating proper oil levels, and an oil fill neck is located on the back right side of the gudgeon for the 9R and 9RX Series Tractor. The oil fill is located on the top of the common reservoir on the left side of the 9RT Series Tractor and a fill tube is located between the steps and engine of the tractor.

• Provides increased filter capacity compared to previous 9R and 9RT Series Tractors
• Transmission, hydraulic, and axle oil should be changed every 1500 hours
• Filter should be changed every 1500 hours unless filter restriction code occurs
• Daily and 10-hour inspections of the transmission hydraulic oil level are recommended

NOTE: The tractor should be off and parked on level ground with the hitch in the lowered position when checking the oil level.

• Sight glass observations will be significantly higher with hot oil temperatures and lower with cold oil or if engine has not run long enough.

 
NOTE: Oil level above the top mark on the sight glass can result in power loss and heat generation during transport applications.

Oil change intervals

Tractors with the 9.0L (549.2-cu in.) and 13.5L (823.2-cu in.) John Deere Power Systems engines feature a 500-hour change interval when using approved John Deere Plus-50™ II oil and a John Deere oil filter.

Tractors equipped with the Cummins QSX 15-L (915.4-cu in.) engine have a 400-hour engine oil and oil filter change interval.

• Previous initial oil and filter change at 100 hours is no longer required due to the factory fill of Break-In™ Plus oil.
• If using anything other than John Deere Plus-50 II oil, a 250-hour change interval is required.  CJ-4 must still be used.
• Only use ultra-low sulfur diesel fuel and CJ-4, ACEA E9, or ACEA E6 oil.
• An oil change of 500 hours is possible when using fuel with less than 15 parts per million (ppm) of sulfur, along with John Deere Plus-50 II oil.

See the tractor's operator's manual for oil change intervals and further details.

Fuse and relay panel

The electrical fuse and relay panel is located behind the operator’s seat and just below the cab's rear window. Simply lift up on the operator manual cover for access.

• Contains easy-to-replace automotive blade-type fuses and relays for quick servicing.
• Spare fuses are provided for each amperage size used.

The diode module contains many of the diodes contained in the system:

• If a diode problem occurs, simply replace the diode module for easy service and increased uptime.
• Relays are also fully interchangeable for quick service.

 

Electrical system (smart load center) 

The electrical system provides a full controller area network (CAN) bus based system on the tractor for improved tractor implement integration and flexibility. Incorporated with the system is a smart load center, which provides fewer fuses, fewer connectors, and simplified wiring for increased reliability.
 
The solid-state load center’s primary function is to control the majority of high-current loads, such as fender floodlights and the horn. This electronic circuitry will monitor loads and voltages to provide fast reaction time and the ability to alert the operator if a circuit overloads or if voltage is out of specification – for example, open circuit (undercurrent) or short circuit (overcurrent).

Cab air filters

The cab fresh air filter is conveniently located beneath the left side of the cab for all 9 Family products:

• External service means no mess in the cab from dusty filters
• Filter housing acts as a dust accumulator compartment
• Hand screw eliminates need for tools
• Replace cab fresh air filter every 1000 hours or sooner if plugged or damaged

Cab air recirculation filter is located in the roof liner above the operator. 70 percent of the total air volume is recirculated with a blanket effect for enhanced operator comfort.

• Replace cab air recirculation filter every 1000 hours or sooner if plugged or damaged. 

Cab air filters are not designed to filter out harmful chemicals. Follow the instructions in the implement operator’s manual and those given by the chemical manufacturer when using agricultural chemicals.

Toolbox

A convenient toolbox is located on the left-hand side of the front frame for tool storage and comes standard on all 9R, 9RT, and 9RX Series Tractors.

9R and 9RX Series Tractors have an additional storage box conveniently located on top the left-hand platform.

The 9RT has an additional toolbox conveniently located next to the left side of the batteries for additional storage.

The front tow cable is recommended for pulling all 9 Family Tractors in time of needed assistance. Tow cables are available as a factory-installed option on all ag tractors and are base equipment on all Scraper Special Tractors. The tow cable attaches to the area in front of the drawbar and is also available as a field-installed option.

9RX Series Tractors equipped with 45.7-cm (18-in.) and 61-cm (24-in.) tracks feature a maximum speed of 42 km/h (26 mph).

 

9RX Series Tractors equipped with 45.7-cm (18-in.) or 61-cm (24-in.) tracks are advised to reduce ground speed based on axle load. 9RX Series Tractors equipped with 45.7-cm (18-in.) tracks will have a top speed set at the factory of 31 km/h (19 mph). Maximum speed may be adjusted up to 42 km/h (26 mph) upon review of the transport speed recommendations in the Operator’s Manual.

 

The speed reduction allows the undercarriage components and tracks to dissipate heat buildup caused by the higher axle loads, reducing undercarriage component and track damage. Increasing mid-roller surface area will increase the undercarriage ability to dissipate heat.

 

Narrow undercarriage with 45.7-cm (18-in.) tracks feature a narrower mid-roller matched to track width. This results in a smaller mid-roller surface area than 61-cm (24-in.) tracks, which are also matched to track width.

 

Producers who desire a 9RX machine for row-crop work and who also transport long distances with high axle loads should understand the limitations of the 45.7-cm (18-in.) and 61-cm (24-in.) tracks. 61-cm (24-in.) tracks with a greater mid-roller surface area will provide greater undercarriage and machine performance in transport while maintaining the ability to perform row-crop work. Comparing the transport speed recommendations for 45.7-cm (18-in.) and 61-cm (24-in.) tracks, the speed reduction is higher for 45.7-cm (18-in.) tracks for the same axle load.

 

9RX Series Tractors with a wide undercarriage and 76.2-cm (30-in.) or 91.4-cm (36-in.) tracks do not feature a speed reduction with increased axle load.

9RX Series Tractor owners and operators need to be aware of axle loads and the recommended speed. The operator’s manual for both the machine and implement will have information on advised transport speeds. 9RX Series Tractors equipped with narrow undercarriage will also feature an in-cab window decal and reference card stored in the armrest for quick guidance on recommended transport speed based on axle load. Many implements may have a lower recommended transport speed than the tractor,; it is always advised to follow the lowest recommended transport speed.

NOTE: Example implements are for reference and direction only. Weigh the tractor and the amount of weight on the axle to determine the final recommended speed. Weights of implements will vary due to different configurations available between tractor and implement. Never exceed the maximum speed recommendation of any implement.

For producers who wish to limit vehicle top speed, transmission settings can be adjusted on the CommandARM™ display or user profiles can be established which locks out the ability to change vehicle top speed by the operator unless they enter the PIN.

Beginning with model year 2019 production, 9RX Series Tractors equipped with 76.2-cm (30-in.) and 91.4-cm (36-in.) tracks can be equipped with industry-exclusive, factory-installed track spacing set at 304.8-cm (120-in.).

 

9RX Series Tractors equipped with 304.8-cm (120-in.) track spacing provide increased stability, allow producers to operate on 304.8-cm (120-in.) centers for controlled traffic farming, and provide improved track-to-frame clearance for better access to the undercarriage for serviceability and material cleanout. John Deere is the first and only tractor manufacturer to offer a 304.8-cm (120-in.) track spacing option on four-track tractors with 76.2-cm (30-in.) and 91.4-cm (36-in.) tracks up to 462.3 kW (620 hp).

9RX Series Tractors with 304.8-cm (120-in.) track spacing increase space between the undercarriage and chassis to provide more space for performing daily and routine maintenance tasks.
