ABSTRACT:
A three-point linkage for coupling farm implements to a tractor has two lower links pivoted at their forward ends to a tractor and lie in a plane which from the rear to the front ends of the links is downwardly inclined and the links converge towards a point at or near ground level, and an upper link whose center line converges with the lower links towards the said point. In lieu of a single upper link, a pair of links which diverge from one another as they extend toward the tractor are preferred.
