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

Engine features include:

• 159 Nm (117.3 lb-ft) of torque at 3000 rpm for extra lugging power on hills and in tough mowing conditions
• Large 2.091 L (127.6 cu in.) 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

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 TerrainCut™ WAM is equipped with a 157.5 cm (62 in.) center deck and two 106.7 cm (42 in.) wings. Cutting widths are 325.1 cm (128 in.) using all three decks, 238.8 cm (94 in.) using the center deck and either wing deck, and 157.5 cm (62 in.) with the center deck only. All decks are rear discharge. Wings fold for transport and reduce the machine’s width to a narrow 213 cm (84 in.), 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.

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.
• High seat-back profile features body-contoured seat cushions.
• Cushions are ideal for those who seek proper back support. The highly-resilient contoured foam construction allows for all-day mowing comfort.
• A raised seat ensures a commanding view to the front and side mower decks.
• The retractable seat belt is convenient to use.

A JDLink™ M Modem – 4G connects a commercial mower to the John Deere Operations Center, which enables you to manage your fleet more efficiently, increase productivity, and reduce labor costs. With a modem and Operations Center, you are always connected to the work in progress and can make timely adjustments to keep your fleet mowing.

Low-effort controls are conveniently grouped on the right-hand side.

The finger-touch controls are:

• Left mower deck lift/lower switch
• Front mower deck lift/lower switch
• Right mower deck lift/lower switch
• Electronically-controlled throttle lever
• Electronically-activated power take-off (PTO) switch
• Speed-range lever for high, neutral, and low range
• Four-wheel drive (4WD) lever

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

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

The hood and seat platform open for excellent access to the engine and drivetrain. All daily service points are located on the left side of the machine:

• Fuel fill
• Engine oil check
• Engine oil filter
• Hydraulic oil fill
• Hydraulic oil filter
• Air filter restriction indicator
• Engine coolant check

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

• Looks and performs like a rubber air-filled tyre
• No flats means reduced downtime
• Reduces maintenance time and expense
• No need to worry about inflating caster tyres ever again
• Reduced incidents of caster tyres rolling off of the rim
• Semi-pneumatic tyres 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 Organisation for Standardisation (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.

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.
