  • Hay stack mover
    Patent number: 3967742
    Abstract: Hay stacks and bales are loaded, transported and unloaded by a single man. Pivotal lifting tines carried by a mast which attaches to a tractor three-point hitch are maneuvered under a stack or bale. Lift assist wheels coupled with the mast raise the loaded tines to transport the load. A clamp means secures the stack or bale during transport and the tapered tines permit ease of tine withdrawal from unloaded stacks and bales.
