Allis-Chalmers Co. HD10W
The Allis-Chalmers HD10W Tractor / Bulldozer was introduced in 1940. About 1,760 HD-10W units were used by the U.S. military during WW II. The HD-10 continued to be manufactured until 1950.
The HD-10W was the wide-track version of the HD-10, with a 74 inch gauge. Models produced during WW II (until s/n 5574) had tracks with 32 links and five rollers. The reliability of the HD10W in military service moved Allis-Chalmers forward as a producer of tractors following WW II.
