Gleaner N7 Combine Parts

N7 parts and accessories

The Gleaner N7 combine, manufactured from 1979 to 1992, was a powerhouse on the farm, delivering reliable performance year after year. Boasting up to 255 HP and accommodating header widths up to 30 feet, the N7 was designed for high-capacity harvesting. Its innovative rotary threshing system set it apart and quickly made it a favorite among farmers seeking efficient grain separation and reduced grain loss.

Introduced in 1979, the Gleaner N7 replaced the K series combines and quickly became known for its rotary threshing and separation system. Powering the N7 was a robust Cummins L10 diesel engine, producing around 235 to 255 horsepower, with a displacement of approximately 672 cubic inches (11 liters). This engine provided ample power for the combine's demanding tasks. The heart of the N7 was its transverse rotary threshing system. The large rotor design enhanced threshing and separation, allowing for increased harvesting speeds and minimal grain damage. It held approximately 300 bushels in its grain tank, enabling extended harvesting periods before unloading. Its unloading auger reached speeds of around 100-125 bushels per minute. The N7 could handle header widths ranging from 20 to 30 feet, accommodating various field sizes and crop types. Chopper and spreader options distributed residue evenly across the field. Its operator cab provided a comfortable working environment and good visibility, essential for long days in the field. The N7 excelled in harvesting a variety of crops, including wheat, soybeans, corn, and other small grains, because of its capacity and effective threshing system.
