Tractor drawn plough - has main beam which swings left or right and is supported on its free end by height adjustable wheel

摘要

A carrying frame (4) is coupled to the lower members (3) of a tractor coupling, and the main beam (8) of the plough pivots about a vertical axle (9) mounted on that frame (4), assisted by an hydraulic ram (11). Plough shares (10) are fixed at intervals along the beam with double sided mould boards which can work when the beam is right or left. The beam is supported at its free end on a wheel (14) which can be adjusted for height and which runs automatically in the direction of the machine. Its direction can be adjusted independent of the angle of the beam relative to the frame (4), and the angle of the frame relative to the tractor. ADVANTAGE - Has wide working scope and is easily manoeuvrable.
