Engine and Performance
The tractor is powered by the International Harvester C200, a 4-cylinder, liquid-cooled gasoline engine. With a displacement of 3.3 liters (200.3 cubic inches) and a compression ratio of 7.33:1, it delivers 65 horsepower at a rated engine speed of 2400 RPM. The intake system utilizes a dual-stage dry air cleaner.

The hydraulic system utilizes an open-center design with a pump flow capacity of 13 gpm (49.2 lpm). The rear hitch is a Category II type, featuring both position and draft control, capable of lifting up to 3,969 lbs (1,800 kg). An independent rear PTO operating at 540 RPM is standard for implement power.

The tractor has a wheelbase of 84.5 inches (214 cm) and an operating weight of 5,650 lbs (2,562 kg), which can reach 8,690 lbs (3,941 kg) when ballasted. The operator station is of an open design, though it was available with a four-post ROPS or a factory-installed cab for increased protection.
