Abstract
A hitch assembly for joining two implements together for side-by-side field operations. Half of the hitch assembly is carried by each implement drawbar and consists of a collapsable linkages pivotally mounted to the drawbar in a cantilvered fashion. Springs floatingly suspend each linkage for ease for movement between its collapsed stored configuration and an unfolded, extended configuration assembled with the other linkage. Equalizer linkages extend between the assembled hitch assembly and the two implements to maintain fore-and-aft alignment of the two implements and bumper-cable means control the side-to-side spacing of the two implements.
