Gravely ZT HD 44in 21.5HP Kawasaki Zero Turn Mower – Heavy Duty

Constructed with an industrial 10-gauge fabricated steel deck, the Gravely ZT HD 44in 21.5HP Kawasaki zero turn mower withstands continuous high-hour lawn maintenance across rugged residential acreage. Budget stamped-deck mowers flex and twist over uneven lawns, resulting in uneven blade heights and premature chassis fatigue. Gravely engineers this heavy-duty machine with a fully fabricated 44-inch steel deck, a stiff tubular backbone, commercial Hydro-Gear ZT-3100 transaxles, and a 21.5HP Kawasaki FR651V commercial engine engineered to conquer dense grass without hesitation.

Commercial-duty Hydro-Gear ZT-3100 transaxles incorporate steel cut gears and charge pumps to maintain hydraulic line pressure during hot afternoon mowing, driving the machine at forward speeds up to 8 MPH. The deep deck profile pulls air upward through the cutting chamber, discharging dense grass clippings uniformly across the lawn without windrowing. An adjustable high-back suspension seat with padded armrests isolates the operator from harsh ground bumps, ensuring comfortable all-day mowing.
