Tractor-drawn reversible plough - is driven by shaft inside sleeve which has two abutments limiting angle of share-supporting beam relative to shaft

摘要

The plough is turned by a device which includes a sleeve which is fixed solidly with the linkage mounting the plough to the tractor. A shaft is inside the sleeve and has one end supported by a rotating mechanism and the other end articulated to the share carrying beam (3). The sleeve has two diametrically opposed adjustable feet (29) welded to its outer wall to limit the amount of sidesway of the beam and these abut against a stop (30) mounted on a plate (27) fixed to the beam and to an outer sleeve (26). The angle of the beam w.r.t. the axis of the shaft is adjustable by varying the relative positions of the flange on the outer sleeve and the flange (50) on the beam to which it is bolted.
