Abstract
A weight transfer linkage arrangement for connection between the three-point hitch of a tractor, a tool bar carrying agricultural implements and a hitch. The linkage arrangement includes a first parallel linkage connecting the tool bar and the hitch and a second parallel linkage connecting the three-point hitch of the tractor and the tool bar. The first and second linkages are both adaptable to be moved between corresponding cooperative lowered and raised positions, such that the tool bar may be raised and lowered without raising and lowering the hitch. Force applying means are connected to the first linkage to apply downpressure on the tool bar when the linkage arrangement is in a lowered position.
