Introduction
International Harvester 1255
The International Harvester 1255 is an agricultural tractor produced between 1979 and 1985 at the manufacturing facility in Neuss, Germany. Designed for heavy-duty field operations, this four-wheel-drive model represents the engineering standards of its era.
Engine and Performance
The tractor is powered by an International Harvester 6-cylinder turbocharged diesel engine with a displacement of 5.9 liters. The liquid-cooled power plant generates 125 hp (93.2 kW) at a rated engine speed of 2200 RPM, providing consistent torque for demanding agricultural tasks.
Transmission and Drivetrain
The 1255 features a four-wheel drive configuration to maximize traction in various field conditions. Operators can choose between two transmission options: a 20-speed configuration (20 forward and 9 reverse gears) or a 12-speed configuration (12 forward and 5 reverse gears), allowing for precise speed control depending on the implement used.
Hydraulics and Implements
The hydraulic system provides a pump flow of 13.2 gpm (50.0 lpm). For implement operation, the rear power take-off (PTO) offers dual speeds of 540 and 1000 RPM. The rear three-point hitch has a lifting capacity of 10,143 lbs (4,600 kg), facilitating the use of heavy mounted equipment.
Dimensions and Chassis
With a wheelbase of 110.24 inches (280 cm) and an operating weight of 12,215 lbs (5,540 kg), the tractor is built for stability during operation. It is equipped with 14.9R28 front agricultural tires and 20.8R38 rear agricultural tires to support its overall dimensions of 186.61 inches in length and 115.75 inches in height.
Conclusion
The International Harvester 1255 is a robust, high-horsepower tractor engineered for demanding field work. Its combination of high-capacity hydraulics, versatile PTO options, and reliable 6-cylinder engine makes it a suitable choice for large-scale crop production and heavy-duty traction requirements.
