<p>A method of increasing efficiency and avoiding or reducing potential stall conditions is accomplished by configuring a ripper (10) of a track type tractor (11) responsive to a net force vector (F) acting on the ripper (10). The net force vector (F) is indicative of the various forces and pressures acting on the ripper (10), and the values indicative of these forces can be sensed. For instance, the force and value indicative of the force magnitude (46) can be sensed by monitoring driveline torque, whereas the force vector (F) angle can be derived from ripper tilt and lift actuator (17, 18) pressures. The ripper (10) is configured responsive to the force vector (F) magnitude and direction either via a control algorithm, or by inputs generated by an operator.</p> |
