  • Patent number: 4771670
    Abstract: A method and apparatus for slicing, lifting and carrying round bales or the like. The method for slicing the bale consists of making a radial cut through the length of the bale. The radial cut causes the circumferentially wrapped bale fibers to be cut which causes bale to open up. A partial radial cut, leaving the outer bale fibers uncut, can be made leaving bale substantially in a cylindrical shape to facilitate easy transport with a forklift like carrier. The apparatus consists of a mast assembly mounted to raiseable three point hitch of an agricultural tractor or the like. A pair of parallel forks are directly attached to mast and engage the curved sides of bale so as to lift and support bale for easy transport. A hydraulically activated knife assembly is attached to mast and forks. The knife has serrated teeth which cut through bale when knife reciprocates. A bumper or work guide when attached to the end of forks holds bale during cutting process.
