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.
