Introduction
Allis Chalmers 440: Four-Wheel Drive Agricultural Tractor
The Allis Chalmers 440 is a heavy-duty four-wheel drive tractor produced between 1973 and 1977. Manufactured by Steiger in Fargo, North Dakota, this machine was designed for large-scale agricultural operations requiring significant traction and power.
Engine and Performance
The tractor is powered by a Cummins 555C liquid-cooled V8 turbocharged diesel engine. With a displacement of 555 cubic inches (9.1 liters), it delivers 218 horsepower at a rated speed of 2800 RPM. This power output provides a drawbar capacity of 165 horsepower, enabling the machine to handle heavy implements such as 7 to 8-bottom plows.
Transmission and Drivetrain
Power is transferred through an Eaton transmission featuring 10 forward and 2 reverse gears. The drivetrain incorporates a cerametallic dry disc clutch, designed to withstand the high torque requirements of heavy fieldwork. The tractor utilizes four-wheel drive with outboard planetary final drives to ensure effective power distribution to the ground.
Hydraulics and Steering
The 440 features an open-center hydraulic system with a pump flow capacity of 21 gallons per minute (79.5 liters per minute) at a pressure of 2000 psi. It is equipped with three remote valves for implement control. Steering is managed by an articulated hydraulic power system, which provides the necessary leverage to maneuver the tractor's 20,230-pound frame.
Operator Environment and Dimensions
The tractor comes standard with an enclosed cab, with optional air-conditioning available for operator comfort. It measures 228 inches in length and 105 inches in width, with a height of 139 inches. Braking is provided by hydraulic disc brakes, ensuring reliable stopping power for the tractor's substantial weight.
Conclusion
The Allis Chalmers 440 serves as a robust solution for farmers needing a high-horsepower, articulated four-wheel drive unit. Its reliance on proven Cummins engine technology and heavy-duty drivetrain components makes it a suitable choice for demanding primary tillage and heavy pulling applications.
