Abstract
A swivel hitch for chisel plows comprising a pair of vertically spaced flat plates secured at their rearward ends to the transversely extending frame member or tool bar of the chisel plow and having a flat bar pivotally received therebetween. The opposite ends of the flat bar are positioned outwardly of the flat plates and are adapted to be connected to the lower arms of the tractor three-point hitch. The upper arm of the tractor three-point hitch is secured to the existing clevis element secured to the plow frame member or tool bar. A pair of bolts may be extended through the flat plates and the bar for safety purposes during transport.
