Description
When your combine starts leaving grain on the field or you notice the clean grain tank isn’t filling like it should, the problem might be right under your nose—a worn tailings auger drive belt. This belt keeps the tailings system moving, recycling unthreshed material back through the sieves for another chance at separation. Without it working right, you’re literally throwing money away with every pass.
Key Features
- Heavy-duty construction designed to handle the continuous load of moving grain and chaff back through the separator
- Precision-made to fit the original belt path and pulley system without modifications
- Built to resist stretching and cracking even in dusty harvest conditions
- Proper tensioning keeps the tailings auger turning at the right speed for maximum grain recovery
Built for Real Farm Work
This belt fits the classic John Deere combines that have harvested millions of acres—the 6620 and 6622 smaller combines perfect for smaller farms, plus the workhorse 7720 and 7721 models that can handle serious acreage. The 8820 rounds out the group as one of John Deere’s larger conventional combines from that era.
Made to Last
Combine belts take a beating from dust, heat, and constant flexing as the machine moves through the field. This replacement is built with the same materials and construction as the original, so it’ll handle those long harvest days when you’re pushing to beat the weather.
Good to Know
Replacing this belt is straightforward on most of these combines—you’ll need to access the drive area behind the grain tank. While you’ve got things apart, it’s a good time to check the condition of the tailings auger itself and clean any buildup from the housing.
