ABSTRACT:
A tow bar assembly for a tractor which enables up to three implements to be simultaneously pulled through a field utilizing a conventional hitch of the tractor. The tow bar assembly includes hitch dollies which are pivotally mounted so as to be moveable about both horizontal and vertical axes to a primary support beam and a pair of outrigger beams which are pivotally connected at opposite ends of the primary support beam in such a manner that the dollies are permitted to follow the natural terrain when the tow bar assembly is in use. Implements, such as hay balers, may be selectively hitched to the dollies.
