Whether it’s thick wet conditions, overgrown properties, or stalky grasses in its path, the Mach One will easily cut it down to size. Its high-volume output (HVO) Deck provides increased depth from trim side to discharge side so it can process greater material volume. This unit is packed with essential features guaranteed to give you a smooth and consistent ride. An advanced cutting chamber is formed by setting the blades back four inches from the front of the deck for less clumping and more even grass dispersion. Gravely’s exclusive Constant Belt Tension System (CBT) ensures belt tension is maintained, keeping the blade tip speed and cutting results constant. The Mach One is unmatched when it comes to other commercial mowers in the industry.
