1:35 M4 HIGH SPEED TRACTOR (3-in./90mm)

The 18-ton M4 high-speed tractor series has been developed and built by the Allis-Chalmers Manufacturing Company of Milwaukee, Wisconsin, between 1943 and 1945. The design was based upon the T9 and T9E1 was standardized as the Medium Tractor M4 which became the High-Speed Tractor M4. Together with the M5 and M6 High-Speed Tractors, they replaced the older commercial-type crawler tractors which did not meet the requirements of a modern mechanized army any longer. The high-speed tractors could carry both crew and a basic supply of ammunition. Production started in March 1943 and 5552 M4 tractors were assembled until June 1945, plus 259 M4A1 tractors between June and August 1945. The 18-ton M4 high-speed tractor was designed mainly as a prime mover for the 90mm antiaircraft gun, a 3-inch gun.
