LAWNMOWER TILT SENSOR APPARATUS AND METHOD

摘要

A lawnmower comprising a frame, an engine supported by the frame, a mower deck supported by the frame, a rotating cutting blade disposed below the mower deck. A PTO is coupled to the engine and the cutting blade to rotationally drive the cutting blade. A drive system is connected to the frame and coupled to the engine to drive or propel the lawnmower. The lawnmower includes a tilt sensor for sensing a tilt angle representing the orientation of the lawnmower with respect to a horizontal level plane. An signal indicator may provide a notice signal when the tilt angle exceeds a pre-determined check angle. The PTO may be disengaged from the engine to stop rotation of the cutting blade when the tilt angle exceeds a pre-determined limit angle. The drive system generally remains operable to drive the lawnmower when the PTO is disengaged to stop rotation of the cutting blade.
