John Deere® Compatible Premium Feeder House Sprocket (13-Tooth x 2-1/4" Bore)
Keep your
product feeding system in top condition with this premium Australian-made feeder house sprocket. Specifically engineered for John Deere® 50, 60, 70, and 80 Series STS combine harvesters, this sprocket is the ultimate solution for repairing worn drive components to ensure an extended service life for your feeder house chain.
Precision-machined and hobbed from a single piece of high-grade 1045 billet using advanced CNC technology, each sprocket is expertly timed for exact alignment and accuracy. Replacing worn cast sprockets with these extended wear machined units maintains precise chain tracking, offers smoother operation, and protects your
product feeding system from unnecessary wear.
New 2026 High-Performance Design
Our latest 2026 generation sprockets feature a
specialised relief cut at the base of each tooth. This critical engineering upgrade assists with minimising "chain jump" by allowing straw and debris to escape from the bottom of the tooth profile rather than compacting. This ensures consistent chain engagement in heavy crop conditions and contributes to a significantly
longer service life for your entire feeder house assembly.

Expert Maintenance Review
To keep your product feeding system in top condition, we recommend replacing these sprockets as a complete timed set whenever fitting a new feeder house chain.
Standard preventative maintenance using these precision-machined 1045 billet sprockets ensures an extended service life for your chain assembly by eliminating the uneven wear patterns often caused by worn or inaccurately cast OEM sprockets. Replacing the inner sprocket (H159680) alongside the outer sprockets as a matched set prevents the uneven chain tension that leads to premature chain failure and erratic product feeding in high-capacity STS rotors.
Recommended Maintenance Upgrade
For a total system overhaul, we recommend inspecting your Feeder House Chains and Wear Strips. Pairing a new timed sprocket set with a premium chain ensures optimal performance and an extended service life.
