Introduction
International Harvester 6588 Tractor
Produced between 1981 and 1984, the International Harvester 6588 is a heavy-duty, articulated four-wheel-drive tractor. Belonging to the 60 series line, this model was designed to provide high-horsepower performance for large-scale agricultural operations.
Engine and Performance
The tractor is powered by a 7.6-liter (466 cubic inch) turbocharged diesel engine. This six-cylinder, liquid-cooled unit produces 177 horsepower at a rated engine speed of 2400 RPM. It features a bore and stroke of 109 x 136 mm, engineered to sustain long periods of high-load field work.
Transmission and Drivetrain
The 6588 utilizes a two-range power shift transmission providing 16 forward and 8 reverse gears. The system allows for clutchless shifting between gear pairs 1/2, 3/4, 5/6, and 7/8, while shifts between 2-to-3, 4-to-5, and 6-to-7 require the use of the clutch. The drivetrain is configured for permanent four-wheel drive, utilizing an articulated hydrostatic steering system to manage its 7,402 kg shipping weight.
Hydraulics and Hitch
The hydraulic system is a closed-center design with a pump flow capacity of 68.1 liters per minute (18 gpm) and a separate steering flow of 45.4 liters per minute (12 gpm). It supports between two and four hydraulic valves for implement control. The rear hitch is a category III/II type, complemented by an independent rear PTO operating at 1000 RPM.
Operator Environment
Standard equipment includes a climate-controlled cab featuring heating and air conditioning. The interior is finished in a burgundy style, with an optional 'Wester' interior finish available. The tractor's dimensions include a wheelbase of 279 cm and a ground clearance of 72 cm, providing stability for heavy-duty traction tasks.
Conclusion
With 642 units manufactured, the International Harvester 6588 remains a notable example of early 1980s articulated tractor technology. It is suited for demanding primary tillage and heavy pulling applications where high horsepower and four-wheel drive traction are required.
