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.
Claims20
A tow bar assembly for use in operatively connecting a plurality of agricultural implements having hitch tongues to the hitch of a tractor having a source of power supply, the tow bar assembly comprising,
- a primary support beam having opposite end portions and a central portion,
- means mounted to said primary support beam for mounting said primary support beam to the tractor hitch,
- a pair of outrigger beams,
- pivot means for pivotally mounting an inner end portion of each said outrigger beams to said opposite end portions of said primary support beam,
- means for pivoting each of said outrigger beams about said pivot means, each of said means for pivoting including a first end pivotally mounted to said primary support beam and a second end pivotally mounted to one of said outrigger beams,
- at least one dolly, and means for pivotally connecting said at least one dolly to one of said outrigger beams, said at least one dolly including a frame supported by at least one ground engageable wheel and a hitch member adapted for selectively pivotally connecting the hitch tongues of an agricultural implement thereto whereby an implement hitched to said at least one dolly is pivotally connected to the tow bar assembly so as to follow the contour of the ground over which the implement is pulled.
A baling implement for simultaneously baling forage material and a plurality of rows and which is attachable to a tractor having a power source, the baling implement comprising:
- a plurality of balers, each of said balers having a hitch tongue,
- a primary support beam having opposite ends and a central portion,
- means mounted to said central portion of said primary support beam for mounting said primary support beam to the tractor hitch,
- a pair of outrigger beams,
- pivot means for pivotally mounting an inner end portion of each said outrigger beams to said opposite ends of said primary support beam,
- means for pivoting each of said outrigger beams about said pivot means, each of said means for pivoting including a first end pivotally mounted to said primary support beam and a second end pivotally mounted to said outrigger beams,
- means for connecting at least one of said outrigger beams to the hitch tongue of one of said plurality of said balers, said means for connecting including at least one dolly having a frame supported by a pair of spaced ground engageable wheels and a joint connecting said dolly to said one of said outrigger beams to permit pivotal movement about both a horizontal and a vertical axis with respect thereto.
