Introduction
Allis-Chalmers D14: A Classic Row-Crop Tractor
The Allis-Chalmers D14 is a row-crop tractor produced between 1957 and 1960. Manufactured in West Allis, Wisconsin, this two-wheel drive machine was designed for versatility in agricultural operations, with 23,050 units built during its production run.
Engine and Performance
The D14 is powered by a 4-cylinder, liquid-cooled vertical I-head engine with a displacement of 149 cubic inches (2.4 liters). It utilizes a carburetor-based fuel system designed for LP gas operation. The engine is rated at 1650 RPM and produces approximately 37 horsepower, providing sufficient output for standard row-crop applications of its era.
Transmission and Drivetrain
The tractor is equipped with a standard 4-speed sliding gear transmission offering 4 forward and 1 reverse speeds. An optional Power-Director transmission system is available, providing 8 forward and 2 reverse gears. The Power-Director features a hand-operated clutch, which allows the operator to shift between high and low ranges without stopping the tractor, enhancing productivity during field work.
Operating Systems and Hitch
The machine features manual steering and mechanical expanding shoe brakes to manage its 1,587 kg (3,500 lbs) operating weight. The rear power take-off (PTO) operates at 540 RPM and includes a live hand clutch, allowing for implement operation independent of the tractor's ground movement. The tractor utilizes the Allis Snap Coupler system for implement attachment.
Dimensions and Specifications
With a wheelbase of 217 cm (85.75 inches) and a total length of 327 cm (129 inches), the D14 is configured for row-crop utility. It features 5.50-16 front tires and 12.00-26 rear tires. The ground clearance is 63 cm (25 inches), while the rear tread width is adjustable between 137 and 203 cm (54 to 80 inches) to suit various row spacings.
Conclusion
The Allis-Chalmers D14 remains a representative example of mid-century American agricultural engineering. Its combination of a live PTO, flexible transmission options, and adjustable tread widths makes it a capable tractor for collectors and historical farming enthusiasts.
