What the N6 is used for
The N6 was built for high-output corn, soybean, wheat, and small-grain harvesting on larger farms and custom operations of its time. Its capacity supported 30-foot platforms and, in suitable conditions, the first 12-row corn-head applications offered in the United States.
Today it is mainly used by classic-equipment owners and lower-acreage operators with mechanical ability and access to parts machines. It can still harvest effectively, but it is an older machine whose condition and support network are decisive.
Why the Gleaner N6 stands out
The N6 is notable as one of Gleaner's first major rotary combines and an early expression of the brand's transverse-rotor identity. Its wide-header capability, substantial grain tank, and distinctive Allis-Chalmers power make it a recognized and collectible high-capacity combine from the early rotary era.
Buying a used Gleaner N6
Examine the rotor, cage, concaves, accelerator rolls, feederhouse, clean-grain and return elevators, unloading augers, hydrostatic drive, and all variable-speed drives for severe wear. Check the 426 engine for cooling, fuel-system, and oil-leak issues, inspect wiring and push-button controls closely, and verify that manuals and a realistic parts source are available. Horsepower and detailed specifications can vary by year and configuration, so confirm them with TractorData.com and manufacturer records.
