The Power-Rack Big Square Bale Feeder (including flaker attachment) hooks on a truck or tractor and runs off its 12-volt system. With bale loaded onto the feeder bed and twine cut, the rack pushes it toward the back until a flake drops off. (The rack's retaining "fingers" hold the next flake in place until one pushes a button on the remote.) Flakes can be spaced out so the animals feeding on one flake don't step on the next one. The feeder has very few wear points; and if any parts need replacing, they can be obtained at a hardware store. The Power Rack can be ordered for 3' x 3', 3' x 4', or 4' x 4'bales and is available in two models: one bale per single axle and two bales per single axle.
