1600 Turbo Series III Wide-Area Mower

The 1600 Turbo Series III WAM is powered by a liquid-cooled, turbocharged, four-cylinder, 60-hp (44.7-kW) at 3000 rpm, PS diesel engine.

Engine features include:

• 117.3 lb-ft (159 Nm) of torque at 3000 rpm for extra lugging power on hills and in tough mowing conditions
• Large 127.6-cu in. (2.091-L) displacement, which produces the torque needed to handle hills and tough mowing conditions

  Engine is a 16-valve (four valves per cylinder, two intake and two exhaust) design:

• Cold-start device to increase engine timing for improved cold starting
• Full-pressure lubrication for positive lubrication with continuous operation on slopes
• Dual-element air filter that is completely sealed for effective cleaning

• Progressive-type air-restriction indicator to let operator know when the filter needs servicing
• Automotive-type alternator (75 amp) that provides plenty of charge to the battery
• Glow plugs for quick starting in cold weather
• Automotive sensing system, which tells the operator when the engine is ready to start
• Isolated engine mounting, which reduces engine vibration in the operator's station for more comfortable operation

Direct fuel injection

• Injects fuel directly on top of pistons for more efficient combustion, less emissions
• Delivers more power per gallon of fuel
• Quicker starting and quieter operation
• Designed to meet California emission standards
• Features low levels of exhaust and emissions and excellent fuel economy. It meets the necessary Environmental Protection Agency (EPA) Tier 4 standard and meets 97/68/EC EU non-road mobile machinery (NRMM) emissions regulation
• Electronic engine control and cooled exhaust gas recirculation (EGR) system
• High-pressure common fuel rail for lower emissions and improved engine responsiveness

Flow of exhaust during engine operation

• Exhaust airflow enters into the EGR cooler from the exhaust manifold near the turbocharger
• Cooler takes hot exhaust gases and cools them to where the temperature will not have excessive impact on combustion efficiency
• Based on load, air temperatures, and rpm, the engine control unit (ECU) opens (or closes) the EGR valve, allowing exhaust gases into the intake manifold. The gases mix with the rest of the incoming air from the turbocharger and aftercooler.

Other engine features:

• Overhead valve (OHV) for efficient combustion
• Liquid-cooled for more consistent operating temperatures
• Closed crankcase ventilation that burns crankcase hydro-carbon evaporation

• Deluxe air-intake system
• Hood that is composed of a large, black, cross-link polyethylene-composite center section with green, metal side panels
  • The composite center section includes air-intake screens and helps to guide the cooler air from above the machine to the radiator. The design provides a uniform distribution of clean air, as well as minimizing the amount of chaff collection on the exterior screens.
• Additional sealing around the operator station reduces the amount of hot air blowing on the operator, which in turn improves operator comfort.
• The rear bumper helps with hood sealing and reduces the potential for rear hood damage.

22 gal. (83.3 L) of fuel on board, plenty for a long day of mowing

The operator can fill the fuel tank without removing the hood. The fuel tank capacity is 22 U.S. gal. (83.3 L) for all-day mowing.

An innovative, exclusive air-intake system draws clean air from the top of the machine instead of the rear. This keeps the radiator cleaner and prevents the engine from overheating.

The high-capacity cooling system combines the radiator and hydraulic oil cooler.

The 1600 Turbo Series III WAM is equipped with a 62-in. (157.5-cm) center deck and two 42-in. (106.7-cm) wings. Cutting widths are 128 in. (325.1 cm) using all three decks, 94 in. (238.8 cm) using the center deck and either wing deck, and 62 in. (157.5 cm) with the center deck only. All decks are rear discharge. Wings fold for transport and reduce the machine’s width to a narrow 84 in. (213 cm), so it can easily be driven along golf-cart-size paths or fit on a trailer. The wing decks will float 45 degrees above horizontal and 20 degrees below horizontal, following the ground contour.

All decks have a unique baffling system that reduces clumping and provides even clipping dispersal for exceptional appearance.

 

Features common to these rear-discharge mower decks include:

• Mower decks are fabricated from 7-gauge, 0.179-in. (4.6-mm) steel, the thickest in the industry; strength has been designed into the 1600 Turbo Series III WAM mower decks for increased reliability
• A 3/4-in. (1.9-cm) solid bar runs along the entire mower deck perimeter for added strength
• Dual-range height of cut spans 1 in. (2.54 cm) to 5.5 in. (14 cm) in 0.5-in. (1.27-cm) increment adjustments
• Wing deck float of 45 degrees upward and 20 degrees downward provides excellent cut quality when mowing undulating terrain
• Each wing deck has four caster wheels to follow ground contour and provide unmatched cut quality
• Unique baffling system produces even grass dispersal for superior appearance

Patented impact-absorbing system

A patented impact-absorbing system is provided:

• This exclusive feature allows the wing decks to move rearward and inward when contacting obstructions such as trees, curbs, or other solid objects to prevent damage.
• Mowers are safety certified (meaning that mowers have been evaluated by the manufacturer [John Deere Turf Care] and conform to American National Standards Institute [ANSI] B71.4 Safety Certification Specifications for Commercial Turf Care Equipment).

Isolated deck motor design

The isolated deck motor design consists of three cast-iron mounting structures for the deck motors. Rubber isolators that are similar to engine mount isolators are located between the castings and the deck shell brackets.

 

The rubber isolators allow the castings to flex relative to the deck shell. The addition of the isolators stops the vibration path between the hydraulic motor and the deck shell, thus preventing the amplification of sound by the deck shell.

Deck motors

1. Radial case drain
2. Pressure balanced bronze-on-steel thrust plates
3. Flexible configuration of shaft, flange, and ports
4. One-piece steel gears with 12-tooth profile
5. Heavy-duty, low-friction sleeve bearings
6. Integrated dust protector
7. High-strength ductile iron body and covers
8. High-temperature Viton® rubber shaft seals
9. Figure 8 monolithic high-temp load seals

The deck motors are capable of withstanding high pressure requirements for all-day mowing. Motors have Viton seals, which can withstand higher hydraulic temperatures. The motor contains a dust seal to help eliminate debris from entering into the hydraulic connections.

Lift valve

The lift valve controls the cylinders that lift and lower the decks. It also controls the axial piston deck-motor pump (turns it on and off).

Mow valve

The mow valve controls the hydraulic flow to the wing deck circuits.

Mower mulch kit available

A mulch kit is available as an attachment for field conversion. The mulch kit includes unique mulch blades, baffles, and a deflector shield to produce smaller clippings, which decompose faster than un-mulched clippings. Operators should follow the one-third rule when mulching grass.

This mulch kit also does an excellent job when mulching leaves.

BTC10335 TriCycler Mulching Kit

NOTE: Applicable for serial numbers starting with 1TC1600TPBT100007 and higher, model year 2012 and newer.

• Used along with the periodic service chart (located in the engine compartment) to determine when service procedures need to be performed on the machine and mower deck

Engine glow plug light

The engine glow plug light indicates the intake manifold heater is energized. The operator should wait until the glow plug light goes off before starting the engine.

• The manifold heater is controlled by a temperature-sensitive timer and turns off sooner in warm weather.
• Starting the engine before the indicator turns off wastes fuel, creates smoke, and puts unnecessary wear on the starter.
• If the starter does not engage when the key switch is turned to the start position, one of the start conditions has not been met. Trouble codes are presented as a sequence of flashes and pauses that must be counted and converted to a two digit number:
  • One flash, a short pause, and two flashes – operator attempted to start the machine without the park brake locked and the operator is off of the seat (one of these conditions must be met for the starter to engage).
  • One flash, a short pause, and three flashes – operator attempted to start the machine with the power take-off (PTO) engaged.
  • Two flashes, a short pause, and one flash – hydrostatic pedals are not centered in the neutral position.

Engine coolant temperature light

The engine coolant temperature light indicates the engine is overheating. A warning beeper also sounds when the light comes on.

Engine oil pressure light

The engine oil pressure light indicates the engine oil pressure is low. The indicator should be lit as a test to make sure it is working when the key switch is turned to the run position. A warning beeper sounds when the light comes on. The light (and beeper) should go off once the engine starts.

Battery discharge light

The battery discharge light indicates the battery is not getting enough charge from the alternator. The light should come on when the key switch is turned from off to run. The light should go off once the engine starts.

• Quick access to a drink and tools on the machine decreases downtime.

Power take-off (PTO) drive provides control and power

Mower decks are hydraulically driven using a separate closed-loop system with one gear-type motor for each deck:

• Mowers are designed to provide increased torque to the decks for additional power and productivity in tough mowing conditions.
• The operator can raise one or both of the wing decks and all hydraulic power will be directed to the center deck (exclusive John Deere feature) to provide maximum hydraulic pressure for extreme conditions.
• Blades are belt-driven from each deck motor.

Safety starting system

The 1600 Turbo Series III Wide-Area Mower (WAM) has an operator-presence system.

In order to start the engine, the following must be met:

• The hydrostatic foot controls must be in neutral.
• The power take-off (PTO) must be disengaged.
• The operator must be in the seat or the parking brake must be set.
• The ignition key must be used.

In addition, once the engine is running, an interlock automatically shuts the engine and PTO off if the operator leaves the seat. To keep the engine running, the operator must disengage the PTO and set the parking brake before dismounting.

A hydrostatic transmission is used for reliable operation.

Durability features include:

• Large, forged, one-piece trunnion shaft with large support bearings to reduce vibration and noise
• Charge pump used to efficiently deliver oil to the transmission
• Oil cooler to cool transmission oil for longer transmission life
• Pressure-side filtration to allow use of a finer mesh (10 micron filter) than suction filtration systems

High-range/low-range transaxle allows the following:

• High range has maximum speed of 15 mph (24.1 km/h) for faster transport. Power take-off (PTO) can be engaged for mowing in high range.
• Low range has a maximum speed of 9 mph (14.5 km/h). The wide-area mower (WAM) can mow in both low and high range.

The differential lock is standard equipment:

• It locks both the front drive wheels together for extra traction, when needed.
• Conveniently located pedal allows the operator to engage the differential lock.

Planetary final drive and wet-disc brakes ensure durability and long life

• Require minimal adjustment
• Include individual turn brakes as standard

Mechanical rear-wheel drive

Two-function mechanical rear-wheel drive is standard equipment:

• On-demand four-wheel drive (4WD) automatically engages and disengages as needed. The machine operates in two-wheel drive (2WD) until front-wheel slip is detected. If front-wheel slip is detected, the machine then automatically engages 4WD in the forward direction.
  • Constantly maximizes trimming ability
  • Better fuel economy than full-time 4WD
  • Less steering tire wear than full-time 4WD
  • Increases traction and trimming ability to allow a novice operator to mow like an expert
  • Works in the forward direction only
• Full-time 4WD is on only when shifted into position by the operator.
  • Can be engaged or disengaged on the go
  • Provides maximum traction and flotation in difficult operating conditions
  • Works in reverse as well as the forward direction

The wing decks rise to a narrow 84-in. (213.4-cm) width and can be locked into transport position. A machine transport speed of 15 mph (24.1 km/h) means the operator can spend less time transporting and more time mowing.

NOTE: The power take-off (PTO) can be engaged while in the transport position.

Proper trailering strap areas

 

Fasten the machine to the trailer with heavy-duty straps, chains, or cables. Fasten the rear strap to the tow loop behind the rear axle. Fasten the front strap to tie down holes on the operator's platform. Both the front and rear straps must be directed down and outward from the machine.

Bumper

The rear, frame-mounted bumper provides for excellent rear protection and effective hood sealing for engine cooling.

To operate, pull out on the bottom of the engine cover latches on the left and right side of machine behind the operator’s seat. Unhook the tops of the engine cover latches from the hooks on the engine cover. Push down on the bumper lever and rotate the bumper to the right side of the machine.

The wing decks raise 90 degrees, and the front deck raises 70 degrees for excellent access.

No tools are required to access the mower deck belts.

Diagnostic control module

The diagnostic control module features light-emitting diode (LED) lights and a heartbeat to aid in diagnostics and lead the technician to the proper circuit. Each switch on the machine has its own LED light on the controller, so input and output functions can be diagnosed by observing the appropriate lights.

Service ADVISOR™ diagnostics system

Service ADVISOR is a John Deere dealership tool capable of providing technical and machine support for technicians and service managers using a laptop computer. It provides symptom-based diagnostics information, machine information, electronic technical information, and connection to John Deere through an extranet at workshops and in the field.

A data port outlet socket is provided on the right-hand instrument panel next to the diagnostic control module console to access important service information with a laptop computer equipped with Service ADVISOR software. Service ADVISOR reduces downtime by allowing technicians to quickly identify the root cause of problems, aid them in identifying the component needing repair, and aid them in the repair procedures. It also significantly reduces the amount of printed materials the technician is required to have at their disposal to perform the repair or maintenance work.

Quick-access foot panel for easy access

The foot panel is easily removed to allow quick and easy access to service points.

Large, 18x9.5-8 steering (rear) and 26x12-12 (front) drive tires provide excellent traction and flotation. Both tires have a six-ply rating.

Caster tires

Semi-pneumatic mower deck caster tires are standard equipment. Benefits provided by semi-pneumatic tires include:

• Looks and performs like a rubber air-filled tire
• No flats means reduced downtime
• Reduces maintenance time and expense
• No need to worry about inflating caster tires ever again
• Reduced incidents of caster tires rolling off of the rim
• Semi-pneumatic tires never need air maintenance, nor will they become flat when punctured, making them truly flat-free

The two-post folding Roll-Gard ROPS and seat belt are standard equipment:

• When used in combination with seat belts and safe operating practices, the ROPS is effective in reducing serious injuries and death from rollover accidents.

The standard-equipment Roll-Gard ROPS can be folded to allow for additional clearance when needed. With the ROPS in the folded-down position, the machine fits under a standard doorway.
  
The ROPS meets the International Organization for Standardization (ISO) 21299 ROPS standard – defined test procedures and acceptance criteria for the rollover protective structures of powered ride-on turf care machinery. Under the support of the Outdoor Power Equipment Institute (OPEI), a panel was formed that brought together an international group of ROPS experts that presented the best-learned practices regarding off-highway vehicle operator crush protection. The result of this undertaking is a standard dedicated to protecting operators of powered ride-on turf maintenance equipment.

The ROPS can be folded down without tools for operation under tree canopies or in other confined operating spaces. Operators should leave the ROPS in the upright position for all other mowing:

• The folding ROPS enhances operator safety and still provides clearance when loading on enclosed trailers.

Folding the ROPS is simple - remove two pins and rotate the top of the Roll-Gard ROPS down. Adjustments can be made from the operator's station.

The folding ROPS performance is certified at the date of manufacture, per the following standard:

• ISO 21299

Due to the high percentage of operators who prefer the four-post ROPS canopy, a factory-installed option is available. The rear ROPS structure is a black fixed two-post ROPS.

The ROPS comes standard with a canopy and assembles to the 1600 Turbo Series III Wide-Area Mower (WAM) along with a two-post
Roll-Gard™ ROPS.

The four-post ROPS structure includes the following:

• Two front posts
• Rear ROPS
• Welded top and bottom assemblies
• Molded canopy

The four-post ROPS provides the ability to meet bid requirements that call for a four-post ROPS and offers the ability to use a weather enclosure. It also meets the International Organization for Standardization (ISO) 21299 standard.
