MOTOR GRADER BLADE SUPPORT MEANS AND SIDE SHIFT MECHANISM A B S T R A C T An improved support means for mounting the grader blade assembly of a motor grader on depending support arms of the motor grader circle. A bearing housing structure which is several times wider than the height of the blade assembly consists of a transverse hollow structural member with integral upright bearing housing at its ends which are substantially wider than and pivoted on the arms so the structure may be tilted. Forwardly open lower jaws in the bearing housings have planar top and rear surfaces and front lower webs which are generally complementary to surfaces of a lower support rail on the blade assembly; and forwardly open upper jaws provide upper and lower front webs and a planar rear surface which are generally complementary to surfaces of an upper support rail on the blade assembly. Working forces are trans- mitted from the rails through the jaws and bearing housings to the support arms; and vertical forces are transmitted almost exclusively through the lower jaw. A hydraulic cylinder and piston unit for shifting the blade assembly endwise is mounted in the hollow structural member of the bearing housing structure and is removable therefrom endwise.
