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
Air filter with air-restriction indicator Air filter with air-restriction indicator
Air-restriction indicator Air-restriction indicator
  • 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

  • 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
Isolated deck motor design 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.

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.

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

Tires Tires

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
Caster tire Caster tire

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

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

Two-post Roll-Gard ROPS Two-post Roll-Gard ROPS
ROPS folded down for clearance ROPS folded down for clearance

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.
