Allis Chalmers S

The Allis Chalmers S is a powerful crawler tractor built for tough agricultural work. It runs on tracks instead of wheels, making it great for working in muddy or uneven fields. The tractor has a strong diesel engine with four cylinders and a very high displacement of 675.1 cubic inches. This engine runs at a low speed of 1050 rpm, which helps it save fuel and last longer.

This tractor is big and heavy, weighing 20,100 pounds. It's 146 inches long, 97 inches wide, and 74 inches tall. The S model has a 5-speed gear transmission for moving forward and one gear for going backward. It uses manual steering and has an electric starter that runs on 6 volts. The engine is cooled by liquid, and the tractor can hold 50 quarts of coolant to keep it running smoothly in hot weather.
