International Harvester 1086 specifications

What the 1086 is used for

The 1086 is sized for demanding field work, large hay tools, and high-load PTO applications. Its claimed 130 PTO hp and roughly 12,700 lb 2WD operating weight place it well above utility-tractor duties.

The standard cab includes air conditioning, while open-station and four-post ROPS versions were available. Two- and four-wheel-drive configurations were offered, so tire, axle, and front-end configuration should match the intended work.

Why the International Harvester 1086 stands out

The 1086 was built in Rock Island, Illinois, and International Harvester produced 47,420 units. It combines a 6.8 L diesel with either an 8-speed gearbox or a 16-speed TA transmission, Category III hitch, and independent 540/1,000 rpm PTO.

Buying a used International Harvester 1086

Test the Torque Amplifier under a meaningful load and make sure it shifts and holds in both ranges without slipping. Inspect cab air-conditioning operation, hydraulic outlets and hitch response, brakes, clutch adjustment, front axle or drive components as fitted, and the condition of the 90-quart transmission-hydraulic oil system.
