Introduction
International Harvester 340 Utility Tractor
The International Harvester 340 is a utility tractor produced between 1958 and 1963. Positioned as a versatile machine for general agricultural operations, it features a robust 2-wheel drive configuration and was designed for mid-range field tasks and implement management.
Engine and Performance
The tractor is powered by a 166 cubic-inch (2.7 L) 4-cylinder liquid-cooled engine, with a diesel variant introduced as an option in 1960. It produces 47 horsepower at a rated engine speed of 2000 RPM. The engine delivers 129 lb-ft of torque at 1400 RPM, providing consistent pulling power for various agricultural implements.
Transmission and Drivetrain
Operators have access to three distinct transmission configurations: a standard 5-speed sliding gear transmission, a 5-speed Fast Reverser, or an optional 10-speed partial power shift transmission equipped with the International Harvester Torque Amplifier. This variety allows for precise speed selection depending on the specific load and field conditions.
Hydraulics and PTO
The 340 is equipped with an independent rear PTO operating at 540 RPM. The hydraulic system supports up to three valves. Standard flow is rated at 9.3 gallons per minute (35.2 lpm), with an optional high-capacity pump available to provide up to 17 gallons per minute (64.3 lpm) for more demanding hydraulic attachments.
Mechanical and Dimensions
Built on a 73.5-inch wheelbase, the tractor features manual steering with an optional hydrostatic power steering upgrade. Braking is handled by independent mechanical disc brakes. The machine utilizes the IH Fast Hitch system for efficient implement coupling and offers various tire configurations to suit different soil and crop requirements.
Conclusion
The International Harvester 340 serves as a reliable utility platform for farmers requiring a balance of power and maneuverability. Its range of transmission options and hydraulic capabilities make it well-suited for a variety of general farming duties, reflecting the engineering standards of the late 1950s and early 1960s.
