Gravely 991278 ZT HD 60 Zero Turn Mower | 26HP Kohler

Gravely 991278 ZT HD 60 Zero Turn Mower

The Gravely 991278 ZT HD 60 represents the absolute maximum in residential wide-area productivity, featuring a massive 60-inch cutting deck engineered for homeowners who manage expansive acreage requiring 26 HP of high-torque Kohler performance. This flagship ZT HD unit utilizes a powerful 747cc V-Twin motor to ensure zero-turn mowing efficiency is maintained at the highest residential level, providing the massive displacement and frame rigidity required to transform vast acreages into manicured turf without the engine bogging typically associated with standard riders.

Built with a fully welded tubular chassis and dual Hydro-Gear ZT-3100 commercial-grade transaxles, the drivetrain handles the high inertial mass of a 60-inch triple-blade deck effortlessly. Because the 10-gauge fabricated steel shell manages significant discharge volumes, owners must perform routine underside cleaning to preserve optimal aerodynamic lifting power, ensuring the blades produce a surgical finish while the large caster tires and 850-pound operating weight provide the stability needed for managing expansive residential landscapes throughout the year.
