Models depicted on this site may be shown with optional equipment.

  • Only two Access-Eze™ lubrication points cut maintenance time up to 95%
  • Self-tensioning belts minimize cost and labor on routine maintenance

  • Extra-deep, 5.5-inch deck is fabricated from heavy-gauge formed steel with a reinforced anvil edge
  • Specially designed cutting chambers enhance airflow for better cut quality
  • 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

  • Commercial Use: 3-year unlimited hours; limited warranty covering parts and labor.
  • Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.

  • Robust G2 transmission features 7-micron absolute filter and CoolFan™ hydro cooling system
  • HydroGear variable displacement 16 cc piston-pumps and high-torque Parker wheel motors
  • Provides 1,000-hour transmission fluid change interval

  • Deep-cushioned, high-back, foam-padded, scuff-resistant Cordura®-covered seat with padded lumbar support and armrests
  • Roomy, iso-mounted, shock-absorbing footrest

  • Raise and lower the deck easily with foot pedal and drop pin for precision cutting heights between 1.0 and 5.0 inches.

  • Standard, low profile Roll-over Protection System (ROPS) structure with an adjustable seatbelt
  • Dampened steering levers that return to neutral from forward and reverse
  • Interlock switches that shut down the engine when the operator leaves the seat while PTO is engaged or levers are in drive position

  • ComfortZone™ seat eliminates jostles and jolts with coil-spring suspension and a fully padded, high-back seat, padded armrests and variable density foam cushion. Iso-mounting smooths the ride, erases fatigue and keeps the operator comfortably in control at faster mowing speeds
  • Operational controls including throttle, choke and angled View-Eze™ console and adjustable cup holder are well positioned for visibility and ease of reach
  • One- or two-handed operation with ComfortReach™ adjustable Hydra-Smooth™ dual levers that automatically return to neutral from either forward or reverse position.

  • 896 cc, air-cooled OHV Vanguard Big Block V-twin engine with horizontal crankshaft for longer life

  • Robotically-welded steel construction for long-lasting durability
  • Centered-bearing design provides greater load-bearing capacity to handle the weight of operator, fuel and high-capacity collector with reserve strength for curb shocks and weight shifts
  • Tough-as-nails powder-coated finish is fusion-bonded for chip and rust resistance

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.

  • 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

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.

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

Available for all MidMount models, optional QuikAjust Tilt™ steering levers (except 124V-41) with "no tools" adjustment provide a 9-inch range for maximum comfort and fit while maintaining natural arm and wrist positions..

LED work lights provide improved visibility in low light situations.

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.

Dedicated 48-, 52- or 61-, or 72-inch rear discharge decks throw clippings out back for a smooth cut and no windrowing.

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

The Electric Height Adjustment kit offers 1- to 5-inch height adjustment control from the operator's seat with the flip of a switch. This dealer-installed option is available for all 200 and 300 Series MidMount™ models.

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.

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.

Optional DuraGuard™ Rear Bumper Guards protect the rear of the mower while preserving easy access for removal of the rear service shield. Available on the 220, 223, 227, 300 Series and 400 Series.

Provides an additional two inches of leg clearance.

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

Optional low-pressure, high-flotation bar-tread tires are available for 61- and 72-inch models that flex with the terrain for maximum traction and minimize scuffing caused by wheel spin-out.

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.

The optional Premier Suspension Seat offers the ultimate in comfort and an extra measure of suspension while mowing over rough ground. Adjustable backrest, armrests and lumbar support with weight-adjusted suspension control provide maximum comfort for operators of all sizes and preferences.

The Filter Minder alerts the operator when airflow is restricted in the air canister on dual-element air filters. The Filter Minder is available as an option on all 616T and 700 Series FrontMount™ models (except 721DT, 725K and 727EFI) with heavy duty canister-type air cleaners.

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

Diamond-plated aluminum canopy is highly resistant to abrasions. Easily mounts to ROPS to increase operator comfort by limiting exposure to direct sunlight and reducing eye strain.

"I'm a true believer in Grasshopper, and I've tried about every machine on the market. It's the easiest and most dependable machine. The way Grasshopper makes the decks is better – it gives a more professional cut. I've been in business cutting lawns for over 20 years and I can't imagine growing my business without Grasshopper. My dad is part of my company, and that makes going to work very special."

— Joey C, Cedartown, GA


"I am enjoying my retirement years caring for the beauty of over 2500 acres. These acres include areas around two (2) ponds and two (2) gated entrances into a 1700-acrea hunting plantation. Obviously I needed "mower" than the "run-of-the-mill" equipment. The 61" 300 series, air cooled Grasshopper was the answer for me. It's a champion at tackling high and wet grass and the ease of handling and zero turning makes me feel like a champion too. "

— C Gary T, Claxton, GA


"The features that I enjoy are: the grass is cut evenly at all times, runs very smooth, and sets higher than other mowers which enables you to see all your surroundings at all times. Ever since I got the mower it's a dream come true, which makes me want to mow more than I have. That makes the Grasshopper so much mower."

— Don P, Friendsville, TN
