MOTOR GRADER BLADE MOUNTING AND TILT MECHANISM A B S T R A C T A motor grader has a circle with integral, depending arms at the rear, and the lower ends of the arms extend for- wardly so that blade carrying means, comprising bearing housings pivoted at their lower ends to the extremities of the arms, extends upwardly in very close proximity to the fronts of the arms. Two hydraulic cylinder and piston units for tilting the blade carrying means are carried in sleeves which are integral with and between the arms, directly be- hind the upper end portions of the blade carrying means, which permits the use of very short stroke pistons that are well protected from damage by earth and rocks piled up by the blade. In addition the units are mounted in spherical bearing and socket means for limited universal movement within the sleeves. Further, the piston rods extend along shallow chords of a circle struck about the pivots which mount the bearing housings, so working forces are applied substantially axially to the piston rods in all positions of the bearing housings.
