Allis Chalmers HD11

The Allis Chalmers HD11 is a powerful crawler tractor built for tough agricultural work. Made from 1955 to 1965, this tractor has tracks instead of wheels, making it great for working in muddy or uneven fields. It's a big machine, measuring 154 inches long, 40 inches wide, and 84 inches tall, with a heavy weight of 21,000 pounds.

The HD11 is powered by a strong diesel engine made by Allis Chalmers. This engine has 6 cylinders and can produce 110 horsepower, which is above average for tractors of its time. It has a liquid-cooled system that holds 44 quarts of coolant to keep the engine running smoothly. The tractor has an open operator station, meaning the driver sits outside without a cab. It uses an electric starter to get the engine going and has special band brakes to help it stop. With 6 forward gears and 3 reverse gears, the HD11 can handle different speeds for various farming tasks.
