<p>A stack mover has a stack-receiving assembly provided with a horizontal tube and a plurality of forks on the tube. A U-shaped carrier for the assembly has a shaft at its bight passing through the tube and a pair of arms supported by caster wheels. A power cylinder between the assembly and the carrier raises the shaft and the tube to lift the stack as the arms swing about the wheel axles. Connections between the tube and a tractor limit the extent of rotation of the tube relative to the shaft. When used with the three-point hitch of a tractor the entire mover may be raised for full support by the tractor.</p> |
