    Due to the high percentage of customers who prefer the four-post ROPS canopy, a factory-installed option is available. The rear ROPS will be a black fixed two-post ROPS structure similar to prior-model wide-area mower ROPS.

    The ROPS comes standard with a canopy and assembles to the 1600 Turbo Series II 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.

    ROPS foldedROPS folded

    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 permit additional clearance, when needed. With the ROPS in the folded position, it fits under a standard doorway.
    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 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

    Isolated deck motor design
    Isolated deck motor designIsolated deck motor design

    Isolated deck motor design consists of three updated 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.

    • Large 122-cu in. (1995-cc) 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
      • Completely sealed for effective cleaning
    Air-restriction indicatorAir-restriction indicator
    • Progressive-type air-restriction indicator to let operator know when the filter needs servicing

    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 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 systemDeluxe air-intake system
    1600 Turbo Series II WAM side view1600 Turbo Series II WAM side view
    • Deluxe air-intake system
    • Hood that is composed of a large cross-link polyethylene composite piece with green side panels
      • The composite part helps to guide the cooler air from above the machine to the radiator. The design provides a more uniform distribution of air, as well as minimizing the amount of chaff collecting 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.
