These U-blades are designed for pure production: moving bulk material at the lowest cost in time and fuel. 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. The side wings are angled toward the center, and the moldboard is both tall and curved to push the material to the center of the blade and cause it to roll. The bottom line is that this blade will move more with less effort than using another blade type.
