Introduction
International Harvester 1456
The International Harvester 1456 is a heavy-duty agricultural tractor produced between 1969 and 1971. Part of the manufacturer's high-horsepower range at the time, it was engineered for demanding field operations, offering robust performance for row-crop and heavy traction tasks.
Engine and Performance
The tractor is powered by the International Harvester DT407, a 6.7-liter, 6-cylinder turbocharged diesel engine. This liquid-cooled power unit is designed for sustained load applications, delivering 144 horsepower at a rated engine speed of 2400 RPM. The engine features a dual dry element air cleaner to ensure longevity in dusty field environments.
Transmission and Drivetrain
Operators have access to two transmission configurations: a standard 8-speed gear transmission or the Torque Amplifier, which provides a 16-speed partial power shift capability (16 forward and 8 reverse gears). This flexibility allows for precise speed adjustment under varying load conditions. The tractor comes standard with 4x2 2WD, while 4x4 MFWD (Mechanical Front Wheel Drive) was available as an optional enhancement for improved traction.
Hydraulics and PTO
The hydraulic system features a pump flow of 12 gallons per minute (45.4 liters per minute), providing sufficient capacity for standard agricultural implements. The rear independent Power Take-Off (PTO) operates at 1000 RPM, ensuring consistent power delivery to driven attachments. The hitch system is categorized as 3/2, reflecting its capability to handle a wide range of mounted equipment.
Dimensions and Handling
With a wheelbase of 105 inches (266 cm) and an operating weight of 12,800 lbs (5,806 kg), the 1456 provides a stable platform for heavy field work. The machine can be ballasted up to 17,350 lbs (7,869 kg) for increased traction. Handling is supported by hydrostatic power steering and independent hydraulic dry disc brakes, while an optional cab with heating and air conditioning was available to improve operator comfort.
Conclusion
The International Harvester 1456 represents a significant era in tractor engineering, characterized by its focus on high-output power and mechanical durability. It remains a notable machine for collectors and those requiring a reliable, heavy-framed tractor for traditional agricultural applications.
