Introduction
International Harvester 1456
The International Harvester 1456 is a standard-tread tractor produced between 1969 and 1971. Designed for heavy-duty agricultural operations, it represents a significant model within the International Harvester lineup, offering high power output and robust mechanical configurations for field work.
Engine and Performance
The tractor is powered by the International Harvester DT407, a 6-cylinder turbocharged diesel engine with a displacement of 406.9 cubic inches (6.7 L). Featuring liquid cooling and a compression ratio of 17:1, it achieves a rated speed of 2400 RPM. The engine is supported by a dual dry element air cleaner, with an oil capacity of 13 quarts (12.3 L) and a coolant capacity of 24 quarts (22.7 L).
Transmission and Drivetrain
The 1456 provides two transmission options: a standard gear transmission with 8 forward and 4 reverse speeds, or the Torque Amplifier, a partial power shift system providing 16 forward and 8 reverse speeds. The tractor is configured as a 4x2 2WD unit, with an optional 4x4 MFWD configuration available for improved traction. Both transmission systems require an oil capacity of 88 quarts (83.3 L).
Hydraulics and PTO
The hydraulic system utilizes a pump with a flow rate of 12 gallons per minute (45.4 liters per minute). The rear power take-off (PTO) is independent and operates at 1000 RPM, allowing for the consistent operation of heavy implements. The hitch system is categorized as 3/2.
Mechanical Specifications and Dimensions
The machine features hydrostatic power steering and independent hydraulic dry disc brakes. It measures 164 inches (416 cm) in length with a wheelbase of 105 inches (266 cm). The operating weight is 12,800 lbs (5806 kg), which can be increased to a ballasted weight of 17,350 lbs (7869 kg). Standard tire equipment includes 11L-15 front tires and 18.4-38 rear tires.
Conclusion
With 144 horsepower and substantial weight, the International Harvester 1456 is engineered for demanding traction and heavy field operations. Its availability in both row-crop and wheatland configurations, combined with optional power-shift transmissions and cabin climate control, made it a versatile choice for large-scale agricultural enterprises during its production period.
