Introduction

Farmall B-450 Row-Crop Tractor

The Farmall B-450 is a row-crop tractor produced between 1959 and 1970 in Doncaster, England, by International Harvester. Designed as a robust agricultural workhorse, this model was built to address the demands of mid-century farming operations.

Engine and Performance

The tractor is powered by a 4-cylinder diesel engine with a displacement of 264 cubic inches (4.3 liters). It produces 55 horsepower (41.0 kW) and delivers 200 lb-ft (271.2 Nm) of torque at 1100 engine RPM. The engine is liquid-cooled and utilizes an electric starter for operation.

Transmission and Drivetrain

The B-450 features a two-wheel drive system equipped with a mechanical rear differential lock to improve traction in field conditions. Power is transferred through a gear-type transmission providing five forward gears and one reverse gear, utilizing a 305mm dry disc clutch.

Hydraulics and Hitch

The hydraulic system utilizes an open-center design with a total capacity of 3.6 gallons (13.6 liters) and an operating pressure of 2000 psi (137.9 bar). The rear hitch is a Category II configuration capable of lifting up to 6,240 lbs (2,830 kg), facilitating the use of heavy implements.

Dimensions and Chassis

With an operating weight of 5,930 lbs (2,689 kg) and a wheelbase of 79.5 inches (201 cm), the tractor provides a stable platform for field work. It features manual steering and an open operator station. The front axle clearance is 19.6 inches (49 cm), designed to accommodate various row-crop clearance requirements.
