Abstract

774,321. Tractor power-lift mechanisms. BOSCH GES., R. Jan. 7, 1955 [Jan. 9, 1954], No. 505/55. Class 79(1). [Also in Group XXIX] In a hydraulically operated power lift for tractors a working cylinder 2 and a reservoir are formed integrally as a block, the block being provided with a flange for resiliently supporting a control valve unit (not shown). A piston rod 21, a crank arm 20, a lifting shaft 19 and a filter (not shown) are disposed inside the reservoir.
