International Harvester 1568 specifications

What the 1568 is used for

International Harvester built the 1568 for heavy tillage and other high-power row-crop work. It used the distinctive DV-550 truck-derived V8 diesel in a conventional 66 Series tractor layout.

Today, most surviving machines are collector tractors, show tractors, or occasional-use working tractors. Owners who work them should account for the age and specialized nature of the V8 engine.

Why the International Harvester 1568 stands out

The 1568 stands out for its DV-550 V8, low production of 862 tractors, and unmistakable sound and appearance. These traits make complete, well-maintained examples especially desirable to IH collectors.

Inspect the DV-550 for starting, smoke, oil pressure, overheating, and evidence of costly engine work; test the two-speed power shift and all gears under load, then inspect axle leaks, brakes, hydraulics, cab condition, and model-specific parts availability.
