Abstract
756,077. Tractor power lift mechanisms. HOWICK, A. W. Dec. 22; 1954 [Jan. 7, 1954], No. 432/54. Class 79 (1). In a tractor hydraulic power lift mechanism having a control lever O movable upwardly from a neutral position to raise the lift arms A and downwardly from the neutral position to lower the arms A, a device, which comprises a shaft E connected by a link C to an extension B of one of the arms A and having an arm G connected to a link H having a bolt K thereon, is provided whereby the lever O is returned to its neutral position by abutment with the bolt K when the arms A have reached their predetermined lower position. As shown, the link H carries a slot J adjustably carrying the bolt K having a wing nut L and projecting through a slot M in the quadrant N of the control lever O. In a modification, Figs. 4 to 6 (not shown), the link C is connected to an arm pivotally carried on the shaft carrying the power lift arms, the arm having an adjustable connection to a quadrant fixed to the power lift shaft.
