A ground working machine having a frame, a ground engaging wheel mounted to the frame and movable between a raised position not engaging the ground and a working position engaging the ground. The ground engaging wheel, when in the working position, rotating about a wheel axis as the machine is moved over the ground. An actuator raises and lowers the ground engaging wheels. A control system includes a sensor to detect rotation of the ground engaging wheel and a controller that receives an input from the sensor. The controller commands the actuator to raise the ground engaging wheel when the sensor detects that the ground engaging wheel is not rotating.
