Introduction
Allis Chalmers HD19 Crawler Tractor
The Allis Chalmers HD19 is a heavy-duty agricultural crawler tractor produced between 1947 and 1950 in Springfield, Illinois, USA. Designed for demanding field operations, it represents a significant example of post-war American agricultural engineering, with 2,650 units manufactured during its production run.
Engine and Performance
The tractor is powered by a General Motors 6-cylinder liquid-cooled 2-cycle vertical I-head blower diesel engine. It features a displacement of 426 cubic inches (7.0 liters) with a bore and stroke of 4.25 by 5.00 inches. With a compression ratio of 16.0:1, the engine delivers 143 horsepower at a rated speed of 1,750 RPM. The cooling system has a capacity of 41.6 liters, and the engine utilizes an oil bath air cleaner to ensure efficient operation in dusty agricultural environments.
Transmission and Drive
The HD19 utilizes a torque converter transmission system, which provides smooth power delivery under heavy loads. It is equipped with a 2-forward and 1-reverse gear configuration. The machine operates on a crawler drive system, which, combined with power steering, allows for precise maneuvering and optimal traction on uneven or soft terrain.
Dimensions and Operator Station
This crawler tractor is characterized by its substantial mass, weighing 40,395 lbs (18,323 kg), which provides the necessary stability for deep tillage and heavy pulling tasks. The operator station is of an open design, offering clear visibility of the implements and the surrounding work area.
Electrical System
The electrical system is supported by a generator and a 12-volt starter. The tractor is configured with two 6-volt batteries to provide the necessary current for engine starting and auxiliary operations.
Conclusion
The Allis Chalmers HD19 is a robust, high-traction machine suited for heavy-duty agricultural applications where stability and pulling force are critical. Its combination of a torque converter transmission and heavy-duty crawler track system made it a specialized tool for demanding soil conditions during the late 1940s.
