Introduction
International Harvester 1455: Row-Crop Tractor (1979-1981)
The International Harvester 1455 is a row-crop tractor produced between 1979 and 1981 in Neuss, Germany. Designed for heavy-duty agricultural operations, this model represents a significant evolution in the manufacturer's lineup, combining substantial engine power with mechanical versatility.
Engine and Performance
The tractor is powered by the International Harvester DT-402, a 6.6-liter, 6-cylinder turbocharged diesel engine. It features liquid cooling and produces 145 hp (108.1 kW) at a rated speed of 2200 RPM. The engine generates a maximum torque of 390 lb-ft (528.8 Nm) at 1600 RPM, providing the necessary pulling force for demanding fieldwork.
Transmission and Drivetrain
The 1455 features four-wheel drive and a mechanical rear differential lock to ensure traction in varied soil conditions. Transmission options include a 12-speed synchronized gearbox (12 forward and 5 reverse) or a 16-speed creeper transmission (16 forward and 7 reverse), allowing for precise speed control during specialized tasks.
Hydraulics and Hitch
Equipped with a category III/II rear hitch, the tractor offers a lift capacity of 10,143 lbs (4600 kg). The hydraulic system utilizes a pump with a flow rate of 13.21 gpm (50.0 lpm), supporting the operation of implements. The independent rear PTO operates at a standard 1000 RPM.
Dimensions and Operator Environment
The tractor has a wheelbase of 110.24 inches (280 cm) and a ground clearance of 18.7 inches (47 cm). With an operating weight, including the optional cab, of approximately 13,309 lbs (6036 kg), the machine provides a stable platform. An optional, heat-equipped cab is available to enhance operator comfort during long work shifts.
Conclusion
The International Harvester 1455 is a robust, high-horsepower tractor engineered for intensive agricultural applications. Its combination of a high-torque engine, multiple transmission configurations, and significant hydraulic lift capacity makes it a reliable choice for professional farming operations requiring sustained power.
