STRUCTURE OF ROTARY ATTACHED ROLLING CONTROL SYSTEM

摘要

The attitude of an implement mounted on the three-point linkage of a tractor is maintained constant by a sensor which detects the left- right slant angle with respect to the ground and operates to effect extension or contraction of cylinder (8) controlling one of the drop links. A sensor detects the lift angle of the lift arms (3,3') with respect to the tractor and a sensor monitors lengthwise displacement of the link. The width between draft links (4,4') is adjustable to accommodate different implement hitches, and the connection (8) between the drop links and links in movable for and-aft-and vertically.
