Description
During regular weekend lawn maintenance routines, the Gravely ZT X 42in 21.5HP Kawasaki zero turn mower delivers clean cutting performance and zero-radius agility across compact residential properties. Homeowners with suburban lawns lose precious hours using slow riding tractors that struggle to trim around landscape beds and trees. This compact zero-turn mower features a fabricated 42-inch 11-gauge steel deck, responsive Hydro-Gear EZT hydrostatic transaxles, and a commercial-grade 21.5HP Kawasaki V-twin engine that slices through dense grass at speeds up to 7 MPH.
Dual Hydro-Gear hydrostatic transaxles provide smooth directional control, tracking straight along property borders and pivoting smoothly around obstacles. The deep fabricated deck structure generates high airflow velocity that lifts grass blades upright, dispersing fine clippings uniformly across the lawn. A convenient foot-operated deck lift allows operators to raise the deck effortlessly when navigating over tree roots, garden hoses, and exposed rocks.
