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.
Claims23
A hitch for a truck having a pair of longitudinally extended frame members, said frame members having rear ends, a transverse rear bumper secured to the rear ends of the frame members, comprising:
- a first support connected to one frame members, comprising:
- a first support connected to one frame member, a second support connected to the other frame member, a transverse base plate secured to said first and second supports, means connecting the base plate to the rear bumper, a transverse tube means located below said bumper secured to said base plate, shaft means rotatable mounted on and extended through said tube means, said shaft means having opposite ends, a first lift draft arm, a second lift draft arm, first upright pivot means connecting the first lift draft arm to one end of the shaft means, second upright pivot means connecting the second lift draft arm to the other end of the shaft means:
- said first and second lift draft arms being movable from rearward extended positions to folded positions below said bumper whereby said first and second lift draft arms can be folded adjacent each other below said bumper, means for holding the first and second lift draft arms folded adjacent each other, means limiting the rearward extended positions of the first and second lift draft arms, a first crank arm secured to one end of the shaft means, a second crank arm secured to the other end of the shaft means, a first piston and cylinder assembly connected to the first crank arm, a second piston and cylinder assembly connected to the second crank arm, means connecting the first piston and cylinder assemblies to the frame members, and means for supplying fluid under pressure to the first and second piston assemblies whereby the first and second piston assemblies operate to rotate the shaft means to selectively raise and lower the first and second lift draft arms.
A hitch for a vehicle having longitudinally extended frame members, said frame members having rear sections, a transverse rear bumper secured to the rear sections of the frame members, comprising:
- support means connected to the frame members a transverse shaft means having opposite ends, means rotatably mounting the transverse shaft means on said support means, a first lift draft arm, a second lift draft arm, first upright pivot means connecting the first lift draft arm to one end of the shaft means, second upright pivot means connecting the second lift arm to the other end of the shaft means, said first and second lift draft arms being movable from rearward extended positions to folded positions below said bumper whereby said first and second lift draft means can be folded adjacent each other below said bumper, means for holding the first and second lift draft means folded adjacent each other, crank arm means secured to said shaft means, piston and cylinder means connected to said crank arm means and at least one of said frame members, and means for supplying fluid under pressure to the piston and cylinder means whereby said piston and cylinder means operate to rotate the shaft means to selectively raise and lower the first and second lift draft arms.
A hitch for a truck including longitudinally extended frame means having a rear end portion, a transverse rear bumper secured to the rear end portion of the frame means, comprising support means connected to the frame means, transverse tube means located below said bumper secured to the support means, shaft means rotatably mounted on and extended through said tube means, said shaft means having opposite ends, a first lift draft arm, a second lift draft arm, said first and second lift draft arms being movable from rearward extended positions to folded positions below said bumper, first upright pivot means connecting the first lift draft arm to one end of the shaft means, second upright pivot means connecting the second lift draft arm to the other end of the shaft means whereby said first and second lift draft arms can be folded adjacent each other below said bumper, means for holding the first and second lift draft arms folded adjacent each other, means limiting the rearward extended positions of the first and second lift arms, crank arm means secured to the shaft means, extendible and contractable means secured to the crank arm means and frame means, and means for operating the extendible and contractable means to rotate the shaft means to selectively raise and lower the first and second lift arms.
