Abstract
A motor grader having a moldboard and tiltable wheels is provided with a sensor system and electronic controller for determining a required wheel tilt to overcome anticipated draft forces resulting from the angle to which the moldboard is adjusted. The wheels are automatically leaned as determined necessary for counteracting the draft forces. An all-wheel-drive system can be controlled together with wheel lean for counteracting draft forces. Inputs from moldboard tilt and roll, motor grader positioning and orientation and the like can be included in determining anticipated draft forces.
