Ripper operation using force vector and track type tractor using same
Abstract:
A method of increasing efficiency and avoiding or reducing potential stall conditions is accomplished by configuring a ripper of a track type tractor responsive to a net force vector acting on the ripper. The net force vector is indicative of the various forces and pressures acting on the ripper, and the values indicative of these forces can be sensed. For instance, the force and value indicative of the force magnitude can be sensed by monitoring driveline torque, whereas the force vector angle can be derived from ripper tilt and lift actuator pressures. The ripper is configured responsive to the force vector magnitude and direction either via a control algorithm, or by inputs generated by an operator.
