Yellow beacon attaches to OPS or ROPS to provide greater visibility in high-traffic areas.

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.

The optional SpeedTrimming™ heavy-duty, anti-scalp roller kit for 61" and 72" DuraMax® decks (52" and 61" for Stand On decks) speeds close trimming near buildings, fences retaining walls and other landscaping features. Kits available for both left and right sides of cutting decks.

  • PowerVac™ Collection Systems deliver a clean sweep on every pass. Simply adjust your mowing speed to your conditions.
  • Quik-D-Tatch® Vac drive can be removed in seconds without tools

The optional Down Discharge™ mulching package with GrassMax™ medium-lift blades cuts and recuts clippings and directs them deep into the grass bed, enriching turf and producing a beautifully manicured cut.

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.

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.

Creates clean, sharp turf edges along sidewalks, roadways and driveways, eliminating time-consuming secondary trimming and reducing edging time up to 75 percent compared to hand-held string trimmers and walk-behinds.

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

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.

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

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.

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

Provides an additional two inches of leg clearance.

Diamond-plated aluminum canopy is highly resistant to abrasions. Mounts to ROPS or OPS to increase operator comfort by limiting exposure to direct sunlight and reducing eye strain. Canopy tilts up and down to accommodate operator’s size. Optional cooling fan and LED light kit increase operator comfort and visibility.

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

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

Optional 24x12.00x12 turf-tread drive tire for MidMount™ models equipped with 61- or 72-inch decks, performs like a pneumatic tire but without the inconvenience and downtime associated with flat tires. Provides consistent hub height to ensure the mower deck produces an even cut and excellent lateral stability and outstanding operator comfort. Not for use with PowerVac Collection Systems.

Smooth tread, 13x6.50x6 caster wheel. Performs like a pneumatic tire, but without the inconvenience and downtime associated with flats. Not for use with PowerVac Collection Systems, or with DuraFlex Suspension Forks.
