  • 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.

    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.
