Caterpillar’s cushion dozers are used to push load scrapers or track-type tractors. The heavy-duty design includes a wear-resistant center liner plate and a reinforced cutting edge section. The inside-mounted frame is rigid, and the blade height is set to center the pushing load on the push block. Equipped with a cutting edge, the dozer blade can be used for cut maintenance and other general dozing jobs. The 221-1677 model has a 10.25-cubic yard capacity, 138.8-inch width and 69.29-inch height.
