The M8 high-speed tractor was an artillery tractor used by the US Army and Marine Corps from 1950.

Construction

The M8 is a full-track tractor based on the chassis of the M41 Walker Bulldog light tank. It was used to tow cargo trailers and artillery such as the Skysweeper 75 mm anti-aircraft gun and the M59 Long Tom gun. The basic M8 variant could be quickly adapted for carrying projectiles and charges. Unusually for a tractor, the M8's engine was located at the front of the cab. Some M8s were equipped with a hydraulic M5 dozer blade.

History

The M8 was developed following the failure of the T33 cargo-carrier, which was based on the M24 Chaffee light tank chassis. The new, standardized M8 was produced between 1950 and 1955.
