Cat Woodchips U-Blades will move more with less effort than using a standard U-blade. The sidebars on the wings are near vertical for penetration into a pile, this lets the operator cut a load loose from a larger mass of wood chips. The side wings are angled in to the center, and the moldboard is curved to push the material to the center of the blade and keep it rolling. The rolling action makes the material easier to push.
