Introduction
Allis Chalmers HD11 Agricultural Crawler Tractor
The Allis Chalmers HD11 is a crawler tractor designed for heavy-duty agricultural operations. Produced in Springfield, Illinois, USA, between 1955 and 1966, this machine was engineered to provide significant tractive effort and stability for demanding field tasks.
Engine and Performance
The tractor is powered by a liquid-cooled, 6-cylinder vertical I-head diesel engine with a displacement of 516 cubic inches (8.5 liters). It features a compression ratio of 15.0:1 and operates at a rated speed of 1800 RPM. The engine produces a gross power output of 110 hp (82.0 kW) and a net power of 99 hp (73.8 kW). The intake system utilizes an oil bath air cleaner to maintain engine longevity in dusty environments.
Transmission and Mechanical Systems
Equipped with a sliding gear transmission, the HD11 offers 6 forward gears and 3 reverse gears to adapt to various operational requirements. The mechanical drive system relies on 16-inch tracks, which provide the necessary footprint for traction on uneven or soft terrain. Braking is managed through a contracting band system, and the unit features an open operator station.
Electrical and Capacities
The electrical system operates on a 12-volt battery configuration with a positive ground. A 24-volt starter system is utilized for engine ignition. The machine is designed for extended operation with a cooling system capacity of 44 quarts (41.6 liters) and an oil capacity of 17 quarts (16.1 liters).
Dimensions and Weight
The operating weight of the Allis Chalmers HD11 ranges from 21,000 to 22,200 pounds, depending on the configuration and equipment. This weight distribution is critical to the crawler's performance, ensuring sufficient ground pressure for heavy traction applications.
Conclusion
The Allis Chalmers HD11 is a robust crawler tractor suited for heavy agricultural applications requiring high torque and consistent traction. Its mechanical simplicity and substantial build quality make it a representative model of mid-20th-century agricultural engineering.
