Introduction
Farmall 140: Standard Row-Crop Tractor
The Farmall 140 is a two-wheel drive row-crop tractor manufactured by International Harvester between 1958 and 1973. It belongs to a lineage of compact utility tractors designed for versatility in agricultural operations, with a total production run of 66,290 units.
Engine and Performance
The tractor is powered by the International Harvester C-123, a 122.7 cubic-inch (2.0 L) liquid-cooled, 4-cylinder gasoline engine. It operates with a compression ratio of 6.94:1 and features a 1-3-4-2 firing order. The engine is rated at 1400 RPM, delivering 23 horsepower. Air intake is filtered through an oil bath cleaner, ensuring durability in dusty environments.
Transmission and Power Take-Off
The drivetrain utilizes a sliding gear transmission providing 4 forward speeds and 1 reverse gear. Power transmission to implements is achieved through a rear power take-off (PTO) system, which operates at a standard speed of 540 RPM.
Mechanical and Hitch Systems
The Farmall 140 is equipped with manual steering and differential contracting band brakes for stopping control. It features an open operator station and utilizes the IH Fast Hitch (one-point) system, which facilitates the mounting of specialized implements. The tractor rides on 5.00-15 front tires and 11.2-24 rear tires.
Electrical Evolution
The electrical system underwent significant upgrades during the production cycle. Early models were equipped with a 6-volt battery system and a generator. Later units transitioned to a 12-volt electrical system integrated with an alternator, reflecting the technological standards of the time.
