Introduction
International Harvester TD-15 Crawler Tractor
The International Harvester TD-15 is an agricultural crawler tractor produced between 1958 and 1961. Manufactured in Melrose Park, Illinois, USA, this machine was designed for heavy-duty traction tasks in demanding agricultural and industrial environments.
Engine and Performance
The tractor is powered by an International Harvester liquid-cooled, vertical L-head 6-cylinder diesel engine. With a displacement of 554 cubic inches (9.1 liters), it delivers a net power of 105 hp (78.3 kW). The engine is tuned to produce a maximum torque of 386 lb-ft (523.4 Nm) at 1200 RPM, with a rated operational speed of 1650 RPM, providing the consistent pulling force required for crawler applications.
Transmission and Drivetrain
The TD-15 utilizes a shuttle transmission system providing 6 forward and 6 reverse gears. Power is transferred through a 381mm (15-inch) dry disc clutch, allowing for efficient control of the drivetrain. As a crawler tractor, it features 16-inch wide tracks that ensure high flotation and traction on uneven or soft terrain.
Mechanical and Electrical Specifications
The machine features an open operator station design. It is equipped with a 12-volt starter system and a charging system powered by a generator. The electrical setup utilizes two 6-volt batteries. The cooling system has a substantial capacity of 71.9 liters (76 quarts) to manage engine thermal loads during extended operation.
Dimensions and Weight
The tractor has a base weight of 22,540 lbs (10,224 kg). This substantial mass is engineered to maximize ground pressure distribution and stability, essential for the drawbar performance expected of a crawler in this class.
Conclusion
With 3,500 units built, the International Harvester TD-15 remains a notable example of mid-century crawler engineering. Its combination of high torque, shuttle transmission, and substantial operating weight makes it well-suited for heavy-duty field work and earthmoving operations.
