Introduction

International Harvester 300 Utility Tractor

The International Harvester 300 is a utility tractor produced between 1955 and 1956. Part of the 300 series, this model was designed for general agricultural applications and marked a significant milestone for the manufacturer, with nearly 60,000 units produced across all variations.

Engine and Performance

The tractor is powered by the International Harvester C169, a 169-cubic-inch (2.8 L) liquid-cooled, 4-cylinder engine. Configured for LP gas operation, it delivers a rated 45 horsepower at 1750 RPM. The engine utilizes an oil bath air cleaner and requires a 5.7-liter oil capacity for maintenance.

Transmission and Drivetrain

The IH 300 offers two transmission configurations: a standard 5-speed sliding gear transmission or an optional 10-speed transmission featuring the International Harvester Torque Amplifier, which functions as a two-speed power shift. Both options utilize a dry disc clutch and provide the flexibility needed for various field speeds. The tractor is built on a two-wheel-drive chassis equipped with differential mechanical disc brakes.

Hydraulics and Implements

The hydraulic system features a capacity of 3.25 gallons (12.3 L). For implement operation, the tractor is equipped with a 540 RPM independent rear PTO (with Torque Amplifier) and utilizes the IH Fast Hitch system, which was designed to facilitate quick and secure attachment of implements.

Dimensions and Chassis

With a 75-inch (190 cm) wheelbase and an operating weight of 4,313 lbs (1,956 kg), the IH 300 provides a balance of stability and maneuverability. The machine features an open operator station for visibility and can be ballasted up to 6,603 lbs (2,995 kg) for heavier traction requirements. It supports various tire configurations, including 5.50-16 or 6.00-16 front tires and 10-28, 11-28, or 13-24 rear tires.

Conclusion

The International Harvester 300 is a representative utility tractor of the mid-1950s, noted for its reliable C169 engine and the inclusion of the Torque Amplifier system. It remains a functional piece of machinery suitable for collectors and historical agricultural use.
