Abstract
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.
Claims13
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.
A seeding machine having a front portion and back portion, the front portion configured to move in a direction of travel when pulled by a tractor, the seeding machine comprising:
- a plurality of row units, the row units including a seed trench opener and a ground engaging cleaner wheel in front of the trench opener;
- a frame coupled to the row units,
- the ground engaging cleaner wheel 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 the individual cleaner wheels configured to remove crop residue from crop rows which are to be seeded by the seeding machine and over which the ground working machine passes;
- an actuator which is 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 configured to provide input to lower the cleaner wheels after the obstruction is past by the machine;
- and
- a motion detector effective for determining when the machine is in operation seeding and, the motion detector effective to operate the control system to raise the ground engaging cleaner wheels when the machine is in operation.
