摘要:
A drawbar hitch mechanism has a fore-and-aft extending receiver, a gearbox assembly coupled to the receiver and a tongue assembly attached to the gearbox assembly. A first pivot mechanism couples the receiver with the gearbox assembly for side-to-side movement about a longitudinal axis of the receiver. A draft arm is configured to disperse draft loads between the tongue assembly and the receiver. A second pivot mechanism couples the gearbox assembly and the draft arm. The second pivot mechanism is oriented such that it pivots about an upright axis such that the gearbox assembly and second pivot mechanism enable pivoting movement of the tongue assembly relative the receiver.
