Abstract
An improved hitch link assembly for connecting an implement to a tractor. Each of the draft links of a tractor having a three point hitch includes forward and rear link constructions which are interconnected together in such a manner that the rear link construction can reciprocate with respect to the forward link construction between a rearward position and a forward position and can also swing from a generally horizontal position to an angled position with respect to the forward link construction. The rear link construction is in its normal working position when it is in its rearward position and in its generally horizontal position. In addition, novel engaging means are provided to firmly hold the rear link construction in its normal working position.
Claims9
A hitch link assembly for connecting an implement (12) to a tractor (10) characterized by the provision of:
- a forward link construction (36);
- a rear link construction (38) having a forward projection (58);
- mounting means (50, 60) for mounting the rear link construction on the forward link construction for reciprocal movement between a rearward position and a forward position and for pivotal movement from a generally horizontal position to an angled position when the rear link construction is in its rearward position, said rear link construction (38) being in its normal working position when in its rearward and generally horizontal position;
- and
- engaging means (58, 62, 84, 110, 116) operable to firmly hold said rear link construction in its normal working position, the engaging means being engageable with upper and lower surfaces (110, 116) of the forward projection (58) of the rear link construction (38) to firmly hold the rear link construction from pivotal movement when it is in its normal working position, said engaging means further including latching means (62) having transversely extending pin means (68) moveable in an upward and rearward direction into contact with said lower surface (116).
