Introduction

Allis Chalmers S Agricultural Crawler Tractor

The Allis Chalmers S is an agricultural crawler tractor produced between 1937 and 1942 in Springfield, Illinois, USA. With a total production of 1,225 units, this machine was engineered for heavy-duty field operations, utilizing a tracked propulsion system to navigate difficult terrain.

Engine and Performance

The tractor is powered by an Allis Chalmers 4-cylinder, liquid-cooled vertical I-head gasoline engine. It features a displacement of 675.1 cubic inches (11.1 liters) with a 5:1 compression ratio. Delivering 93 horsepower at a rated speed of 1050 RPM, the engine is designed for consistent torque output required for substantial traction tasks.

Transmission and Drive System

The drivetrain utilizes a gear-type transmission providing 5 forward gears and 1 reverse gear. Power is transferred through a dry disc clutch. The crawler drive system, equipped with 18-inch tracks, provides the necessary surface contact area to maintain stability and traction during demanding agricultural work.

Dimensions and Capacities

The Allis Chalmers S has an operating weight of 20,100 lbs (9,117 kg), contributing to its high drawbar pull capabilities. Maintenance requirements include a cooling system capacity of 50 quarts (47.3 liters) and an engine oil capacity of 20 quarts (18.9 liters). The operator station is of an open design.

Conclusion

The Allis Chalmers S is a specialized crawler tractor suited for heavy-duty farming applications where stability and high traction are required. Its robust construction and mechanical design reflect the engineering standards of the late 1930s.
