Patent ID: 7073603

Claim:
A coupling mechanism for coupling an implement to a vehicle, the coupling mechanism comprising: a plurality of links, each having a first end pivotally coupled to the vehicle, and each having a second end pivotally coupled to the implement, the links comprising: an adjustable length upper link, for tilting the implement, the upper link being arranged in a substantially central position in an upper area of the mechanism; a pair of draft links for transmitting towing and pushing forces between the implement and the vehicle, each draft link being positioned in a lower area of the mechanism; and a pair of adjustable length lift links for lifting the implement, each lift link having a first end positioned in the lower area of the mechanism and coupled to the vehicle at points adjacent to a first end of a corresponding one of the draft links, and each lift link having a second end positioned in an upper area of the mechanism and coupled to the implement; and an adjustable-length stabilizer link for controlling oscillating motions of the implement, the stabilizer link being coupled between the draft links.
