ABSTRACT:
A method and apparatus are disclosed for controlling the cross slope angle cut by the blade of an articulated frame motorgrader operated in the crabbed steering mode wherein the articulation angle of the motorgrader frame is sensed and used to calculate the blade angle relative to horizontal required to maintain a desired cross slope angle. The blade angle is sensed and controlled such that the sensed blade angle is maintained substantially equal to the calculated blade angle. The blade angle calculation is performed using the equation:
