The Masport ZVT 4200 is a zero-turn tractor primarily designed for cutting normal residential grass up to 10 inches in height. Its zero-turn capability allows for highly maneuverable operation, making it suitable for navigating around obstacles and achieving precise cuts. The machine is equipped with a cutting deck that can be raised and lowered to adjust cutting height, and a PTO (Power Take-Off) switch to engage and disengage the mower blades. It features a safety interlock system to prevent accidental starting and operation in unsafe conditions.
