  • Publication number: 20220167554
    Abstract: A mower deck hillside adjustment system includes an angle sensor such as an inertial measurement unit mounted to the mower deck for measuring the angle of the mower deck on the roll axis. The angle from the sensor is used to command a left actuator and a right actuator to raise or lower the left side or right side of the mower deck respectively so each side of the mower deck is at the same height to compensate for tire squat and eliminate step cuts.
