Deluxe air-intake systemDeluxe 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.
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
Hydrostatic transmissionHydrostatic transmission

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.

Two-post Roll-Gard ROPSTwo-post Roll-Gard ROPS
ROPS folded down for clearanceROPS 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
Four-post ROPSFour-post ROPS
Four-post ROPS side viewFour-post ROPS side view

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.

Wing decks raisedWing decks raised

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.

Rear bumperRear 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.

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
Patented impact-absorbing system 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
Isolated deck motor designIsolated 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.
