Agricultural tractor coupling mechanism - has two parallel beams with two groups of holes with centre lines crossing each other vertically

摘要

Coupling mechanism for implements to a tractor, connects to a length adjustable top rod, and two lifting arms. Two solid or box-girder beams of equal length and space, parallel positioned, have two series of holes of which the centre line of one series, cross the other series vertically. Mechanism includes e.g. two parallel box girder beams (6,7) with a first series of (8) with (AA) vertical centre line, second series of holes (9) has horizontal centre line (BB). Beam end (10) is near the bottom coupling (1) whilst end (11) is via strut (12)connected to the top coupling (2). Coupling bar (15) includes coupling eyes (6), for linking e.g. to second agricultural implement.
