Three-link coupler for agricultural implements - has lower links swivelably mounted on intermediate pedestal about horizontal axis

摘要

The agricultural implement couple is attached to the rear of a first implement and has two lower guide links and an upper guide link forming a parallelogram. The lower guide links (10), engaging the second implement (5) are swivellably mounted about a horizontal axis (12) on an intermediate pedental (11). They are connected to the first implement (4) by levers (13) mounted above the swivel axis, and by setting members (14, 15) which allow the lower guide rods a restricted degree of freedom. ADVANTAGE - Simple design for moving automatically the second implement centre of gravity nearer to first one.
