Cat Coal U-blades are production oriented: move as much coal as efficiently as possible. The sidebars are vertical through half their length, and angled above for penetration into coal piles without excessive drag or weight. Stainless steel liners are available on some blades to resist corrosion of acidic coal. Optional center push-plates are available for tandem pushing of another dozer.
