Abstract

1,122,520. Earth graders. DEERE & CO. 25 Nov., 1966 [26 Nov., 1965], No. 52942/66. Heading E1F. A grader blade is so supported in an earth grader from to lie beneath a longitudinally extending, chassis-forming between beam between front and rear ground wheels supporting the beam that the blade can be moved laterally of the beam by a ram-actuated, preferably, L-shaped arm pivoted on the beam about an axis parallel to the beam. The arm is connected to the blade by a telescopic, lockable, hydraulically extensible or contractable link so that the blade may be moved laterally of the beam by pivotting of the arm, by actuation of the link, or by manipulation of both the arm and the link.
