摘要

The multi-share reversible plough (1) has a bearing arrangement at the rear, consisting of two parts (3, 4). Between them is a hinge pin (5) passing through fork arms (6) on the outer part (4) and a sleeve on the inner part (3). They are locked in line by a locking pin (9). The outer part has a swinging arm (15) attached with a trailing wheel (17) supported at the end. The wheel can be swung upwards from its operating position for transport. The pivot pin (10) for the arm is located between the hinge pin (5) and two stops (21, 22) attached to the outer end of the outer bearing part (4). The swinging arm (15) is locked onto one of these stops for its raised or lowered position.
