Commercial Mowers | 1600 Turbo TerrainCut™ Wide-Area Mowers

Powerful turbocharged diesel engine for superior performance

1600 Turbo TerrainCut™ Wide-Area Mower (WAM) engine

1600 Turbo TerrainCut WAM engine

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-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

Deluxe air-intake system

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

Fuel tank

Large fuel fill opening

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.

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.

Underside of 62-in. (157.5-cm) deck

Side view of 42-in. (106.7-cm) deck

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

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).

Mow valve

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

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

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

Four-post ROPS

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.
