Abstract: A system for controlling an earth moving machine may comprise: a speed sensor configured to communicate a speed signal indicative of a speed of the machine; an operator bucket lift command input configured to communicate an operator-input bucket lift command; and a controller configured to: receive the speed signal and the operator-input bucket lift command; determine a torque of the machine; using the speed signal and the determined torque, determine a controller-generated bucket lift command; and provide a bucket lift command which is the larger of the operator-input bucket lift command and the controller-generated bucket lift command.
