Bobcat Co. offers a 21-machine lineup including both zero-turn sit-on and zero-turn stand-on mowers, built for commercial and residential customers. Available on the ZS4000 through the ZT7000 mowers is the AirFX cutting system with a bullnose design to lift the grass to the blade. The heavy-duty Hydro-Gear transmission features hydrostatic transaxles for challenging turf conditions. The pump and motor are housed together in a single housing for better durability and reduced maintenance. Rugged, roto-molded dual fuel tanks on the commercial models – ZT3500 through ZT7000 – hold up to 15 gallons. A swing-away bumper gives operators fast access to internal components, making tune-ups more efficient.
