Abstract
A three-point connection on a tractor comprises an upper guide member and a pair of lower guide members and coupling hooks on each of the guide members. A pair of leaf springs are connected between the upper guide member or a traverse bar on the upper guide member and the lower guide member coupling hooks. The leaf springs are each curved in the direction in which it is desired that the leaf springs bend when forces are applied to the ends of the springs.
