Abstract:
1. A ground working machine comprising: a frame; a plurality of ground engaging cleaner wheels mounted to the frame and movable between a raised position not engaging the ground and a working position engaging the ground, individual cleaner wheels when in the working position rotating about a wheel axis as the machine is moved over the ground and configured to remove crop residue from crop rows over which the ground working machine passes; an actuator configured to move at least some of the ground engaging cleaner wheels between the raised and working positions; and a control system including a sensor to detect rotation of the ground engaging cleaner wheels, a controller receiving an input from the sensor, the controller operably connected to the actuator to effect a signal to the actuator to cause the actuator to raise the ground engaging cleaner wheels upon input from the sensor when the cleaner wheels are obstructed and the sensor detects that the ground engaging cleaner wheels are not rotating, the control system providing input to lower the cleaner wheels after the obstruction is past by the machine.
