Implement support linkages

Claim 2

An implement support linkage in combination with a vehicle, the implement support linkage comprising; an implement supporting lower link, one end of which is connected to the vehicle; an adjustable stop mounted on one side of the link remote from said one end, said stop being adjustable towards and away from said one end of the lower link; a stabilizer arm having one end interconnected to the vehicle, and an extension remote from its said one end traversing the lower link and abutting the stop.

Claim 3

The implement support linkage as claimed in claim 1 wherein the lower link is provided with an elongated slot, the extension traversing the lower link by passing through the slot.

Claim 4

The implement support linkage as claimed in claim 2 further characterized by the provision of a check chain having one end secured to the vehicle and the other end secured to the extension adjacent the stop.

Claim 5

The implement support linkage as claimed in claim 3 wherein the extension has a series of holes and the chain is adjustably connected to the extension by a pin passing through one of the holes.

Claim 6

An implement support linkage in combination with a vehicle, said implement support linkage comprising: a pair of laterally spaced apart rearwardly extending elongated lower draft links, the forward ends of which are connected to laterally spaced apart portions of the vehicle; a pair of adjustable stops mounted on the inner rearward side portions of the lower draft links; and a pair of laterally spaced apart generally rearwardly extending stabilizers the forward ends of which are connected to the vehicle at locations outwardly of the forward ends of the lower draft links, and each of the stabilizers being provided with a rearward extension which traverses one of said draft links and is adapted to contact an adjustable stop to limit lateral sway of said lower draft links.

Claim 7

An implement support linkage in combination with a vehicle, said implement support linkage comprising: a pair of laterally spaced apart rearwardly extending elongated lower draft links, the forward ends of which are connected to laterally spaced apart portions of the vehicle; a pair of adjustable stops mounted on the inner rearward side portions of the lower draft links; and a pair of laterally spaced apart generally rearwardly extending stabilizers the forward ends of which are connected to the vehicle at locations outwardly of the forward ends of the lower draft links, and each of the stabilizers being provided with a rearward extension which traverses one of said draft links and is adapted to contact an adjustable stop to limit lateral sway of said lower draft links.

Claim 8

The implement support linkage as claimed in claim 5 wherein each of said adjustable stops comprises a block fixed to one of said lower draft links and a bolt threadingly received in said block, said bolt being arranged to abut said extension to limit movement thereof.

Claim 9

The implement support linkage as claimed in claim 6 further characterized by the provision of a latch associated with each stop to lock said bolt and prevent movement between the bolt and the block.

Claim 10

The implement support linkage as claimed in claim 5 in which each of the lower draft links is provided with an elongated slot, the extension of said stabilizers traversing the links by passing through said slots.

Claim 11

The implement support linkage as claimed in claim 8 further characterized by the provision of a pair of check chains the forward ends of which are secured to said vehicle between the forward ends of the lower link means, and the rearward portions of which are secured to the extensions of said stabilizers inwardly of the sides of the lower draft links.

Claim 12

The implement support linkage as claimed in claim 9 wherein each of said extensions has a series of holes, the chain being connected to said extension by a pin passing through one of said holes.
