Abstract
A motor grader with an adjustable wheelbase. The motor grader may include front and rear wheels supporting a chassis and a main frame. A working blade may downwardly depend from the main frame between the front wheels and rear wheels to perform work on the ground below. The motor grader may also provide an adjustable wheel base to allow the center of gravity of the motor grader to better match the work load being addressed. The adjustable wheel base may also provide more swing clearance for the blade relative to the rear wheels, allow for an adjustable articulation angle, and minimize structural loads on the motor grader, particularly during ripping operation. The wheel base may be adjustable by providing structure through which the relative positions of the rear wheels can be altered automatically, manually, and dynamically.
