<p>A jump mechanism (10) for a plough having a frame (13) and at least one digging shank (11), the jump mechanism (10) includes a main draw bar (14) pivotally coupling the shank (11) to the frame (13) so that the shank (11) can pivot about each end of the bar (14) and a movement control bar (15) also pivotally coupling the shank (11) to the frame (13) so as to govern pivoting of the shank (11) about one end of the main bar (14) relative to the pivoting of the main bar (14) relative to the shank (11).</p> |
