Introduction
International Harvester 5088 Row-Crop Tractor
The International Harvester 5088 is a row-crop tractor produced between 1981 and 1985 in Rock Island, Illinois. Part of the 50 series, this machine was designed to provide high-performance power for demanding agricultural operations, featuring a 150 hp engine and a focus on operator comfort.
Engine and Performance
The tractor is powered by the International Harvester DT-436B, a 7.1-liter, 6-cylinder turbocharged diesel engine. It is liquid-cooled and operates at a rated speed of 2400 RPM. This power plant is engineered for consistent torque delivery in field conditions, supported by a 12-volt electrical system and a robust cooling capacity of 27.4 liters.
Transmission and Drivetrain
The 5088 utilizes the Synchro Tri-Six (STS) partial power shift transmission, offering 18 forward and 6 reverse gears. The system features a dual-lever configuration: the left lever manages gear selection, while the right lever controls the range (high, medium, low, or reverse). It allows for clutch-free power shifting within gear pairs and synchronized shifting between pairs, enhancing efficiency during operation.
Hydraulics and Hitch
The hydraulic system is of the closed-center type, providing a total flow of 67 gpm (253.6 lpm), which ensures rapid response for heavy implements. It is equipped with two valves as standard. The rear Category III hitch provides a standard lift capacity of 6,990 lbs (3,170 kg), with an optional configuration increasing this capacity to 8,280 lbs (3,755 kg).
Operator Environment and Mechanicals
The tractor features a standard cab equipped with heating and air conditioning to support productivity during long working hours. Mechanical control is provided by power steering and a mechanical rear differential lock. Braking is handled by hydraulic wet disc brakes, and the final drives utilize a planetary design for durability.
Conclusion
With 8,176 units produced, the International Harvester 5088 serves as a durable, mid-range row-crop tractor suitable for a wide variety of heavy-duty field tasks, balancing mechanical reliability with advanced operator comfort features for its era.
