Introduction
ATC 400 Agricultural Crawler Tractor
The ATC 400 is an agricultural crawler tractor produced between 1954 and 1956 in Churubusco, Indiana, USA. Part of the 300 and 500 series, this machine was designed for specialized field operations requiring high traction and stability.
Engine and Performance
The tractor is powered by a liquid-cooled, 4-cylinder Continental GD-157 diesel engine. With a displacement of 157 cubic inches (2.6 L), the engine delivers a gross power output of 38 hp (28.3 kW), peaking at 42.5 hp (31.7 kW). It produces 110 lb-ft (149.2 Nm) of torque at a rated speed of 1850 RPM, providing consistent lugging power for heavy-duty tasks.
Transmission and Drive
The drivetrain features a gear-type transmission providing 3 forward speeds and 1 reverse speed, managed by a dry disc clutch. As a crawler tractor, it utilizes 12-inch tracks and spur gear final drives to distribute weight effectively and maintain traction on loose or uneven ground conditions.
Hydraulics and Configuration
The hydraulic system is an open-center design, offering a pump flow rate of 11 gpm (41.6 lpm) to support various agricultural attachments. The operator station is of the open type, focusing on visibility and manual control for the operator during field work.
Conclusion
With a weight ranging from 5,125 to 8,190 pounds, the ATC 400 is a robust, specialized implement for agricultural environments where traditional wheeled tractors may lack sufficient flotation or grip. Its mechanical simplicity and reliable Continental engine made it a durable choice for mid-century farming operations.
