Abstract

912,878. Earth-grading machines. CATERPILLAR TRACTOR CO. Sept. 26, 1961 [Oct. 28, 1960], No. 34398/61. Class 68 (1). Dependant from the underside of an annular frame 16 supported from the frame 11 of a motor grader by a draft assembly 14 and tilt linkage 20 are arcuate segments 30 that extend beneath a grader blade and supporting ring 24 to support the ring over substantially the entire periphery thereof so that it may be rotated about the axis of the frame 16. The segments 30 are so secured to the frame as to allow of vertical and radial adjustment with respect thereto as required.
