COMBINE SPROCKETS

Sprockets are the driving force behind nearly every chain-driven system on your combine — from the feederhouse and grain elevators to the corn head gathering chains and straw chopper. Worn sprockets accelerate chain wear, cause misalignment, and eventually lead to chain failure at the worst possible time. Replacing sprockets and chains together is the right approach to getting full service life out of both.

We stock combine sprockets for the most critical drives on the machine, with OEM cross-reference numbers on every listing for fast, accurate identification across popular combine platforms.

Common Combine Sprocket Applications

• Feederhouse chain sprockets — drive and idler; highest wear location on most combines
• Clean grain elevator sprockets — top and bottom drive for the paddle chain into the grain tank
• Tailings elevator sprockets — return unthreshed material for re-processing
• Corn head gathering chain sprockets — high wear in abrasive field conditions
• Cross auger and unloading drive sprockets — grain handling system drives

When to Replace

• Sprocket teeth are visibly hooked, sharp, or worn asymmetrically
• Chain is jumping or skipping on the sprocket under load
• Replacing a chain — always inspect the mating sprocket and replace together if worn
• Pre-season inspection before harvest

Sprocket wear is gradual and easy to overlook during the season. A pre-harvest inspection is the right time to check tooth profile on your high-wear drives and replace anything that's past its service life.
