Abstract
A material handling machine includes an arm moveable relative to a chassis of the machine, a first hydraulic actuator operable to lift and lower the arm relative to the chassis, a ground engaging implement mounted on the arm and moveable relative to the arm, a second hydraulic actuator operable to move the ground engaging implement relative to the arm, the second hydraulic actuator having a pressured chamber, pressure within the pressure chamber being indicative of a force of engagement between the ground engaging implement and the ground, and a control system. The control system defines a target pressure for the pressure chamber, the control system being arranged such that when a pressure within the pressured chamber exceeds the target pressure the control system operates the first hydraulic actuator to lift the arm to reduce the force of engagement between the ground engaging implement and the ground.
