Abstract

The plough with a ploughshare (2, 3) mounted each side of the plough beam (1) has the beam secured by a pivot (22) on the traction arm (4) which allows it to trip sideways if an obstacle is met. The return system includes a leaf spring (6) bent into an arc. This has one end (3) attached to a pivot system (9, 10) at one side of the crosspiece and the other end (15) attached to a swinging arm (16) attached at the inner end (17) to another central pivot system (18, 19). The outer end of the leaf spring has its pivot connection (15) travelling along a slide block (26) at that end of the crosspiece. The whole is held in a locked position after the beam has returned to its straight position, when the pivot pin (15) travels along the slide block, then up a sloping ramp (28) near the end and into a groove (27) across it, at a higher level.
