Abstract
A system and method for enabling a machine to drive through its parking brake when in first gear include detecting that the machine transmission is in its lowest gear in a selected direction, that the machine parking brake is activated, such that the machine is stationary, and that the throttle setting of the machine exceeds a predetermined throttle threshold value. In this state, one or more auxiliary loads of the machine are dropped to provide additional torque to the ground engaging elements of the machine, such that there is sufficient torque to drive the machine through the parking brake.
