Description
Need to upgrade residential cutting speed without scalping uneven lawns? The Gravely ZT X 48in 21.5HP Kawasaki zero turn mower provides an agile cutting platform that cuts residential mowing times in half compared to traditional lawn tractors. Standard riding tractors struggle to turn around perimeter fences and landscaping trees, requiring constant forward-reverse shifting that drags out property maintenance. This 48-inch zero-turn machine turns within its own footprint, navigating complex residential yard layouts with intuitive dual-lever steering.
A 21.5HP Kawasaki V-twin engine delivers dependable combustion torque to drive twin cutting blades through dense spring grass. Dual Hydro-Gear EZT transaxles provide smooth ground control up to 7 MPH forward speed, while wide rear drive tires protect soft lawn sod from wheel slip marks. The fabricated 11-gauge steel deck features an optimized underside shape that accelerates grass discharge velocity, preventing clumps during fast mowing runs.
