Introduction

International Harvester 4568 Four-Wheel Drive Tractor

The International Harvester 4568 is a heavy-duty articulated four-wheel drive tractor produced between 1975 and 1976. Manufactured by Steiger in Fargo, North Dakota, this machine was engineered for high-acreage field operations requiring significant draft capacity.

Engine and Performance

The tractor is powered by an International Harvester DVT-800, a liquid-cooled V8 turbocharged diesel engine with a displacement of 13.1 liters. It delivers 300 horsepower at a rated engine speed of 2600 RPM. The engine produces 825 lb-ft of torque at 1800 RPM, providing the necessary pulling force for large-scale tillage and heavy implement operation.

Transmission and Drivetrain

Power is transferred to the ground via a continuous mesh transmission offering 10 forward and 2 reverse gears. The drivetrain features an articulated steering system, which allows the tractor to maneuver despite its significant size. It is equipped with a 355.6 mm dry disc clutch and utilizes hydraulic disc brakes for deceleration.

Hydraulics and Dimensions

The 4568 utilizes an open-center hydraulic system. The main pump provides a flow of 17 gpm, while a dedicated steering circuit provides 22 gpm to ensure responsive handling. The tractor has a wheelbase of 118 inches and a shipping weight of 21,900 lbs. It is supported by 24.5-32 agricultural tires on both the front and rear axles, which are built with 3.5-inch diameter bars for structural integrity.

Operator Environment

The tractor comes standard with an enclosed cab featuring factory-installed air-conditioning. This configuration was designed to improve operator comfort during extended work intervals in demanding field conditions.

Conclusion

With 858 units built, the International Harvester 4568 served as a high-capacity solution for large-scale agricultural enterprises in the mid-1970s. Its combination of a high-torque V8 engine, articulated 4WD platform, and substantial weight makes it suitable for heavy-duty primary tillage and large-scale cultivation tasks.
