Introduction
International Harvester 1056 Row-Crop Tractor
The International Harvester 1056 is a row-crop tractor manufactured in Neuss, Germany. Produced between 1982 and 1985, this machine belongs to a series that includes the 956 and 1055 models, designed to meet the requirements of professional agricultural operations.
Engine and Performance
The tractor is powered by the International Harvester D-358, a 5.9-liter, 6-cylinder liquid-cooled diesel engine. It features direct fuel injection and produces a net power output of 105 hp (78.3 kW) at a rated speed of 2300 RPM. The engine generates a maximum torque of 362.1 Nm at 1400 RPM, providing the necessary pull for demanding field work.
Transmission and Drivetrain
The 1056 offers two transmission configurations: a standard 8-speed forward and 4-reverse gear setup, or the IH-Synchron transmission featuring a two-speed power shift that provides 16 forward and 8 reverse speeds. It utilizes a 310mm dry disc clutch, or a cerametallic disc for the power shift version. The drivetrain includes planetary final drives, mechanical rear differential lock, and power steering, with options for either two-wheel or four-wheel drive.
Hydraulics and Hitch
The hydraulic system is an open-center design with a pump flow capacity of 42.0 lpm at a pressure of 161.8 bar. The rear Category II hitch is equipped with position and draft control, capable of lifting up to 4159 kg at the ends. The independent rear PTO operates at 540 and 1000 RPM, engaged at engine speeds of 1920 and 2000 RPM respectively.
Conclusion
The International Harvester 1056 is a robust and versatile tractor suited for a variety of row-crop applications. Its combination of a high-torque 6-cylinder engine, flexible transmission options, and substantial hydraulic lift capacity makes it a reliable asset for agricultural tasks requiring sustained performance and durability.
