Introduction
International Harvester Farmall 340 Row-Crop Tractor
The International Harvester Farmall 340 is a row-crop tractor produced between 1958 and 1963 at the Rock Island, Illinois facility in the United States. Designed for versatility in agricultural operations, it represents the mid-century evolution of the Farmall line.
Engine and Performance
The tractor is powered by a 2.7-liter, 4-cylinder diesel engine. It delivers a rated power of 47 hp (35.0 kW) at 2000 RPM. The engine features a 19.2:1 compression ratio and produces 129 lb-ft (174.9 Nm) of torque at 1400 RPM. It utilizes a liquid-cooling system and an oil bath air cleaner to maintain operational integrity under field conditions.
Transmission and Drivetrain
The 340 offers two transmission configurations: a standard 5-speed sliding gear transmission or an optional 10-speed transmission equipped with the International Harvester Torque Amplifier, a two-speed power shift unit. Both systems utilize a 266.7mm dry disc clutch. The tractor is configured as a two-wheel-drive machine with mechanical differential dry disc brakes and manual steering.
Hydraulics and PTO
The hydraulic system is an open-center design operating at 1500 psi (103.4 bar) with a pump flow of 9 gpm (34.1 lpm). An optional independent rear PTO is available, providing 540 RPM at an engine speed of 1750 RPM, which allows for the operation of various implements.
Dimensions and Chassis
The tractor features a wheelbase of 79.6 inches (202 cm) and an overall length of 117 inches (297 cm). It provides significant flexibility for row-crop work through adjustable rear tread widths, which vary depending on the wheel type installed, ranging from 48 to 117 inches. It is equipped with an open operator station.
Conclusion
The Farmall 340 is a robust, mechanical-focused tractor suited for row-crop applications requiring reliable power and adjustable tread spacing. Its range of transmission options and standard hydraulic capabilities make it a versatile utility machine for mid-century farming operations.
