ABSTRACT:
A hitch assembly is disclosed that is particularly useful for a farm tractor to pull ancillary farm equipment, such as ammonia applicators, across a field to be treated during a farming operation. The hitch assembly is connected to the front of the tractor and has struts that extend outwardly in opposite directions therefrom with the ancillary equipment being connected to the outer ends of the struts so that the ancillary equipment is maintained outwardly from the tractor as the tractor pulls such equipment by movement in a forward direction. The struts have inner and outer portions with the outer portion being hinged to the inner portion whereby the outer portion can be pivoted forwardly about a vertical axis so that the outer portion of the strut can be folded to a position where the outer end of the strut is contiguous to the mount utilized to mount the hitch assembly to the front of the tractor. Ground engaging wheels are mounted on the outer ends of the struts and extendible arms are received in the end portions of the struts to vary the effective length of the struts as needed. Connecting ears are attached to the extendible arms with the ancillary equipment being connected to the ears during operation.
