ABSTRACT:
A motor grader has improved support structure for mounting the grader blade on the circle blade support arms and for controlling blade tilt. A bearing housing structure consists of a transverse structural member with integral upright bearing housings at its two ends, is slightly shorter than the space between the support arms, and is carried on pivots at the lower ends of the arms with facing bearings so the bearing housing structure reinforces the arms against lateral deflection. The grader blade support rails extend through upper and lower jaws in the bearing housings with the weight of the blade carried in bearing plates in the upper jaws and the lower rail guided between parallel upright bearing plates in the lower jaw which is otherwise free of contact with the lower jaw. Blade tilt is controlled by a single hydraulic cylinder pivotally mounted on the circle midway between the arms with its piston rod pivotally connected to the transverse structural member.
