    • Deck easily converts from side discharge to optional Down Discharge™ mulching or PowerVac™ collection
    • Sentry™ spindles with massive, 8-inch flanges anchored in a 6-bolt pattern, spread the force of impact for greater strength
    • Spindle planes are fabricated from double-layered formed steel laminate and combine with the spindles to form a triple-strength deck to keep blades level and deliver a high-quality cut.
    • Sentry™ spindle guards shield spindle housing and seal lower bearings from fiber wrap and dirt ingestion

    Hydraulic Height Adjustment

    • Hydraulic Height Adjustment for MidMount DuraMax™ decks 61-inches and larger allows operators to raise and lower cutting height at infinitely variable settings with toggle switch control. Standard on 400 Series models.

    Ultimate Operator Station™

    Radiator Cleaning Wand

    A multi-channel sprayer that combs water pressure between radiator fins without damage, dislodging packed-in dust and debris that can become an invisible source of engine overheating. Remove and clean radiator screen regularly. A dirty screen will cause the engine to overheat. For use on liquid-cooled models only.

    Sunshade Canopy Vinyl


    Lightweight, water repellent, UV-resistant vinyl canopy mounts easily to OPS or ROPS to limit exposure to direct sunlight, reducing eye strain and increasing operator comfort.

    Custom Cordura® Weather Cover

    Weather-resistant, black Cordura fabric cover with embroidered Grasshopper logo keeps seat and engine area protected during storage or between mowings. Slips over ROPS, with Velcro closure to secure the opening.

    Dedicated 48--inch and larger rear discharge decks throw clippings out back for a smooth cut and no windrowing.

    Shielded Sprayer

    Accepts 53-inch, 30-gallon shielded sprayer, which features aerodynamically designed shields and fully shielded curtains to contain chemical spray. Four-nozzle spraying chambers apply small droplets that "stick" to vegetation for more coverage per tank using less chemicals.

    Wide Seat Conversion Kit

    Provides additional seating room for larger operators or to accommodate cell phones or pagers. Requires seat belt extension.

    Foldable ROPS

    The Foldable ROPS allows the two-post ROPS to be lowered for mowing under low-hanging trees and other overhead obstacles, or for storing and transporting in enclosed trailers with low door clearance. CAUTION: Avoid drop-offs, embankments and steep slopes. Do not allow ROPS to provide a false pretense of security in hazardous areas and avoid questionable conditions. Always wear seatbelt when Foldable ROPS is in up-right position. When Foldable ROPS is down, DO NOT use seat belt, and drive with extra caution.

    DuraFlex™ Suspension Forks

    Optional DuraFlex™ Suspension Forks absorb the impacts of rough terrain to maintain a level cut, and can be set for use with PowerVac™ collectors.

Canopy tilts up and down to accommodate operator’s size. Optional cooling fan and LED light kit increase operator comfort and visibility.

    Bar-Tread Low-Pressure Tires

    Optional low-pressure, high-flotation bar-tread tires flex with the terrain for maximum traction and minimize scuffing caused by wheel spin-out.

    Side Discharge Control Kit

    Control the discharge of the mower deck to avoid putting clippings in flower beds and on sidewalks
