M4 High-speed artillery tractor
The prototype
The M4 High Speed Tractor was developed to transport the 90-mm antiaircraftgun , the 155-mm 'Long Tom' gun and 8-inch / 240-mm howitzers. This tracked vehicle could master all kinds of terrain but it also performed well on paved roads. Depending on the towed load the M4 could reach a max. speed of 56 kmh and climb hills up to 30%. The steering is done by two handles that each influence a track. To come to a stand-still both handles have to be pulled. The crew of 10 would sit in the front compartment. The engine is in the middle of the chassis and the ammunition was stowed in the rear compartiment. A small crane to load and unload the ammunition is fitted. A 13t winch is mounted just above the tow-bar. A total of approximately 5.500 were built in between 1943-1945.
