Abstract
A primary drive line for delivering power from a power-take-off (pto) shaft on a tractor to an input shaft on an implement includes a swivel hitch comprised of an upper gearbox and a lower gearbox. The upper gearbox is fastened to a pair of spaced apart, upper vertical plates carried on a tongue extending forwardly from the implement, and the lower gearbox is fastened to a pair of spaced apart, lower vertical plates carried by a yoke assembly that is attached to the tractor. An output shaft on the upper gearbox is coupled to the implement input shaft. The lower gearbox has two shafts, one of which is coupled to an input shaft on the upper gearbox. The other shaft on the lower gearbox is connected to the tractor pto shaft. A pivot tube secured to the upper vertical plates is surrounded by a pivot housing fastened to the lower vertical plates to permit pivoting movement of the lower gearbox relative to the upper gearbox about a generally vertical axis when the tractor makes turns during normal operation.
