Abstract
A three point hitch mounted on the rear of a pick up truck has a pair of lift draft arms connected to a hay bale carrier. Pivot connections having upright pivot pins attach the lift draft arms to a transverse shaft allowing the lift draft arms to be folded adjacent each other below the rear bumper of the truck. Crank arms secured to opposite end of the shaft are connected to hydraulic piston and cylinder assemblies. The piston and cylinder assemblies are operable to rotate the shaft to selectively raise and lower the lift draft arms and bale carrier mounted thereon.
