2025 John Deere 1600 Turbo TerrainCut™

Powerful turbocharged diesel engine for superior performance

The 1600 Turbo TerrainCut 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

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.

Mower decks have many performance and convenience features

The 1600 Turbo TerrainCut™ 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 TerrainCut™ 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

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

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

Standard high-back, air-suspension seat provided for operator comfort

An air-suspension seat is standard equipment and provides maximum operator comfort across a wide range of operator traits. Key adjustments include the following:

• Weight and height adjustment allow for proper ride and suspension height.
• Damper adjustment that allows the operator to adjust the seat’s ride to their preference:
  • Softer settings increase seat travel to absorb large bumps.
  • Stiffer settings reduce vertical seat travel, reducing movement of the operator’s arms and legs.
• Fore-aft seat slide adjustment helps account for a wide range of heights.
• Fore-aft suspension travel to improve directional changes during operation.
• Back angle tilt adjustment is included for the back portion of the seat.
• Lumbar adjustment provides proper back support.
• Standard, adjustable armrests are made of a durable material that provides adequate support and surface area for the operator's arms.

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.

Excellent performance from high-traction tires and low-maintenance caster tires

Two-post folding Roll-Gard™ rollover protective structure (ROPS)

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

Factory-installed, four-post rollover protective structure (ROPS) order option

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 TerrainCut™ 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.
