  • Tandem 12cc Parker pumps-in-reservoir transmission is specifically designed for turf-care applications
  • In-line CoolFan™ cooling system and integrated, replaceable, high-efficiency fine-particle filter
  • Design directs more power to the cutting deck as power-sapping components are eliminated

Provides 4.5 inches of adjustable range and is positioned to provide a panoramic view of the mowing environment and easy reach of all switches, levers  and controls, including a deep phone/accessory tray with  USB charging ports.

Features an extra-wide, extra-thick pad with embroidered Grasshopper logo.

LED work lights provide improved visibility in low light situations.

  • 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
  • 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

Hydraulically dampened control levers that also provide responsive and effortless maneuvering–including one-hand operation–and return to neutral when released from forward and reverse. Adjustable grip bar accommodates larger and smaller reaches of different operators. 

 

Equipped with coil-spring suspension and dampeners, insulating the operator from vibrations, for a smooth, shock-reducing, floating-action ride and minimal bouncing.

Every Grasshopper mower is designed with a low center of gravity for optimal traction and stability. The centralized location of the engine, T-Drive™ pump and dual fuel tanks on Stand-On models lowers the overall center of gravity, and a total fuel capacity of 9.25 gal/35.0 L reduces the need for frequent refueling.

2-year unlimited hours; limited warranty covering parts and labor.

Cutting height is effortlessly raised and lowered thanks to the smooth motion of the hand-operated lever.

Two USB Charging Ports

The compact wheelbase provides an incredible power-to-size ratio.
Easily fit more units on trailers and maneuver through tighter spaces.

  • Five grease points and easy top-side access to belts and filters
  • 500-hour transmission fluid change intervals
  • Self-tensioning belts minimize cost and labor on routine maintenance

  • 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

  • 810 cc (49.4 cu. in.) Vanguard, V-Twin, OHV engine
  • Heavy-duty components enhance power and reliability
  • Remote-mounted, centrifugal multi-stage air cleaner with advanced debris managements
  • Extended maintenance intervals

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.

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.

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

An optional Air Dam Kit can be installed along the front edge of most mower decks to minimize dust and dirt escaping from the front of the mower.

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

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.

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.
