Return Grain Elevator Chain Sprocket for John Deere 3300-7720 Series Combines

Description

When your combine’s return grain elevator starts slipping or making noise, that worn upper sprocket is usually the culprit. This 7-tooth return grain elevator chain sprocket with 1-inch shaft gets your grain handling system back to smooth operation, ensuring every kernel makes it to the grain tank where it belongs. No more listening to that grinding noise or watching good grain spill on the ground.

What You’re Getting

• Seven-tooth design maintains proper chain speed for efficient grain transport
• Precision-machined 1-inch shaft bore fits your existing elevator drive system perfectly
• Hardened construction stands up to the constant loading of harvest season
• Direct replacement part – no modifications or adjustments needed
• Quality materials resist wear from abrasive grain and chaff

Built for Real Harvest Work

This sprocket keeps the return grain elevator running smoothly on your John Deere 3300, 4400, 4420, 6600, 6620, 7700, or 7720 series combine. These workhorses handle everything from soybeans and wheat to corn, and the return elevator system is what keeps unthreshed grain cycling back through the cleaning system until it’s properly separated. When harvest time comes and you’re running long days, you need every part of that grain handling system working right.

Made to Last

Combine parts take a real beating during harvest – dust, chaff, moisture, and the constant vibration of moving grain through the system. This sprocket uses quality materials and proper heat treatment to handle those demanding conditions season after season. The tooth profile maintains proper chain engagement even as it wears, giving you reliable service through many harvest seasons.

Installation Notes

This is a straightforward replacement that fits right where your old sprocket came out. Check the chain for wear while you’ve got things apart – a worn chain will quickly destroy a new sprocket. Make sure the shaft keyway is clean and the key is in good shape before installation. A little anti-seize on the threads makes future removal easier when the time comes.
