Introduction
International Harvester 433 Utility Tractor
The International Harvester 433 is a utility tractor produced between 1975 and 1980 at the company's manufacturing facility in Neuss, Germany. Designed for general agricultural tasks, this model serves as a reliable workhorse within the 533 series lineup.
Engine and Performance
The tractor is powered by the International Harvester D-155, a 3-cylinder, liquid-cooled diesel engine. With a displacement of 154.75 cubic inches (2.5 liters) and direct injection fuel delivery, it generates 35 horsepower (26.1 kW) at a rated speed of 2050 RPM. The engine cooling system has a capacity of 14.4 quarts (13.6 liters), and the oil capacity is 6.9 quarts (6.5 liters).
Transmission and Drivetrain
The 433 features a two-wheel drive configuration. Operators can choose between two transmission options: a standard 8-speed (8 forward and 4 reverse) or a 16-speed synchronized transmission (16 forward and 8 reverse). Both systems utilize a dry disc clutch to manage power delivery to the wheels.
Hydraulics and Hitch
The hydraulic system provides a pump flow of 7.9 gpm (29.9 lpm) with a system capacity of 3.2 gallons (12.1 liters). The rear hitch is a Category II type, capable of a lift capacity of 3,969 lbs (1,800 kg). Additionally, the tractor includes an independent rear PTO operating at 540 RPM.

The tractor is built on an 81.5-inch (207 cm) wheelbase with a total length of 133.6 inches (339 cm). It features manual steering and disc brakes for control, with a mechanical rear differential lock to enhance traction. The operator station is open by design, with a factory-optional cab available for added weather protection.
