FrontMount™ 900 Series

Liquid-Cooled Diesel

MODEL 900D 1.3L

The Grasshopper zero-turn 900D 1.3L riding lawn mower provides more power, durability and maneuverability than any mower in its class. This mower is equipped with a fuel-efficient MaxTorque™ Clean Diesel Tier 4 Final-compliant engine that burns less fuel per hour than gasoline or propane mowers. The 900D 1.3L saves landscape contractors time by powering through heavy grass at faster mowing speeds while still delivering a manicured cut thanks to the higher torque output of the diesel engine. Replace the front-mounted deck with a wide choice of grounds maintenance implements for year-round productivity. Use PowerFold® deck lift/electric height adjustment to rotate the deck up for easy cleaning and to fit more mowers on a trailer.

  • Add or remove implements in minutes without tools with QuikConverter™ Implement System
  • Equip your out-front mower with a wide range of tools, including turf cleanup, renovation and snow removal implements that extend your productivity year-round

  • Fewer than 10 grease points and easy top-side access to belts and filters
  • 1,000-hour transmission fluid change intervals
  • Self-tensioning belts minimize cost and labor on routine maintenance

Standard on all FrontMount™ DuraMax® decks, PowerFold® is the zero-turn mower industry's first electric deck lift (introduced in 2004).

PowerFold® rotates the deck nearly 90 degrees to provide easy access to the underside of the deck for simplified maintenance and mulching package installation, plus space-saving portability and storage.

The feature also adjusts cutting height between 1.25 and 5.0 inches and controls deck lift functions using a single switch.

  • 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

Electronic Fuel Gauge/ Digital Hour Meter

  • EPA Tier 4 Final-compliant 77 cu. in. (1.3L) , 3-cylinder, liquid-cooled Kubota Clean Diesel engine with horizontal crankshaft and pressure lube for smooth, reliable operation

  • Rugged G3 hydrostatic transmission with auxiliary cooling fans, HydroGear variable displacement 21cc piston-type pumps and high-torque Parker wheel motors with single serpentine belt for more efficient power transfer to the drive.
  • CoolFan™ hydro cooling system with 7-micron absolute filter for cooling efficiency
  • Delivers smooth response and requires less maintenance, with industry-leading 1,000-hour fluid change interval

Wide stance single-fork tail wheels provide increased flotation and stability for a smoother ride.

Hydraulic Lift raises the front of the deck to maneuver over soft or uneven ground and to clear curbs, trailer ramps and other obstacles, operated by a lift switch on the steering lever.

  • Robotically-welded, high-grade steel construction and I-beam reinforcement for long-lasting durability
  • Centered-bearing design provides greater load-bearing capacity to easily 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

LED work lights provide improved visibility in low light situations.

Two USB Charging Ports

  • 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: First two years covering parts and labor; third year covering parts only.
  • Residential Use: 4-year or 800-hour (whichever comes first); limited warranty covering parts and labor.

  • Equipped with a High Temperature Clutch Cut-Out that automatically disengages the PTO if engine temperature reaches a certain point to prevent engine damage

  • The deep-cushioned, deluxe Premium Comfort Seat features a coil-spring suspension and padded lumbar support for all-day comfort. Iso-mounting eliminates vibration before it reaches the seat, and both padded seat and armrests are covered in scuff-resistant, breathable CoolTemp Cordura® fabric, which dissipates heat and won’t tear or crack with extended use.
  • Operational controls including throttle, ignition and push/pull PTO switches, angled View-Eze™ console and adjustable cup holder are well positioned for visibility and ease of reach.
  • One- or two handed operation with QuikAjust Tilt™ dual levers with 9-inch comfort range to custom fit operator's reach. Levers automatically return to neutral from either forward or reverse position and are less strenuous than riding mowers with steering wheels.

Premier suspension seat provides the ultimate in operator comfort. Low-profile seat slides fore and aft and includes an integrated shock absorber that manually adjusts to operators between 100 – 300 lbs. Other ergonomic features include a backrest that tilts from -5 degrees to +30 degrees, a lumbar support mechanism, adjustable armrests and a retractable seat belt.

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

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.

Used in conjunction with PowerFold® electric deck lift/height adjustment, this armrest-mounted switch controls deck lift functions and adjusts cutting height between 1.0 and 4.5 inches on the go.

Allow for controlled side-to-side flotation of the deck in rolling terrain for a smooth, even cut.

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.

Turf-tread tires provide enhanced traction and handling on level terrain. Turf-tread tires are optional for 700 and 900 Series FrontMount™ models.

Every FrontMount™ mower accepts a range of time- and labor-saving QuikConverter™ implements for even greater flexibility and productivity year-round.
