  • Patent number: 7721984
    Abstract: A chain driven push arm advances a hay bale along a bed toward an opening including a pair of vertically aligned, spaced-apart idle wheels each including plural radiating blades. As the hay bale advances along the bed, the wheels rotate freely causing the blades to impinge on successive regions of the hay bale to separate a succession of flakes from the hay bale remainder. The bed is mounted on a wheeled truck or vehicle that is towable behind a tractor as the tractor driver remotely selectively operates the push arm to dispense flakes along the ground. An optional, towable conveyor can be used to load the bed with a succession of hay bales.
