Introduction

International Harvester 4586 Four-Wheel Drive Tractor

The International Harvester 4586 is a heavy-duty four-wheel drive tractor produced between 1976 and 1981. Manufactured by Steiger in Fargo, North Dakota, this model was designed to address the requirements of large-scale farming operations through significant engine power and a robust drivetrain architecture.

Engine and Performance

The tractor is powered by the International Harvester DVT-800, a turbocharged, liquid-cooled, 8-cylinder diesel engine. With a displacement of 798 cubic inches (13.1 liters) and a compression ratio of 15.6:1, the engine is rated at 300 horsepower at 2600 RPM. It produces a maximum torque of 725 lb-ft at 1800 RPM, providing the necessary output for heavy draft applications.

Transmission and Drivetrain

Power is transferred to the ground via a gear-type transmission offering 10 forward speeds and 2 reverse speeds. The tractor features a four-wheel drive configuration utilizing bull gear final drives. Steering is managed by a hydrostatic power system, and the braking system consists of hydraulic wet disc brakes for reliable stopping power under load.

Hydraulics and Dimensions

The 4586 utilizes an open-center hydraulic system with a total flow capacity of 43 gallons per minute (162.8 liters per minute), with 24 gpm dedicated to steering and 19 gpm to the pump flow. The machine rides on a 118-inch wheelbase with an overall length of 241 inches and a width of 116 inches. It is equipped with a Category IV rear hitch, allowing for the attachment of heavy implements.

Conclusion

The International Harvester 4586 represents a high-capacity tractor segment from the late 1970s and early 1980s. Its design, featuring a standard air-conditioned cab and heavy-duty drivetrain, makes it suitable for demanding field tasks requiring high traction and sustained power output.
