When you need to get power from point A to point B on your planter, drill, or field cultivator, a worn-out sprocket can throw off your entire chain drive system. Missing a few teeth here and there might not seem like much, but it’ll cause your chain to jump, wear out faster, and leave you scratching your head when things don’t run smooth. This replacement sprocket gets your drive system back in sync.

What You’re Getting

  • Precision-welded construction that handles the constant stress of field work
  • 21 teeth with proper pitch spacing for smooth chain engagement
  • X-Series hub design that fits standard agricultural shaft sizes
  • Built to work with standard 50 roller chain systems

Built for Real Farm Work

This sprocket is designed for 50 chain applications commonly found on planters, drills, cultivators, and other implements where reliable power transfer is critical. Whether you’re driving seed meters, disk gangs, or hydraulic pumps, this sprocket delivers consistent performance when the planting window is narrow and every day counts.

Made to Last

Farm equipment sprockets take a beating from dirt, debris, and constant operation. This one’s built with welded construction that won’t come apart under load, and the teeth are cut to precise specifications so your chain runs true. The X-Series hub provides a solid connection to your drive shaft without wobbling or slipping.

Good to Know

Installation is straightforward—just make sure your shaft is clean and the keyway lines up properly. If you’re replacing multiple sprockets in your drive system, it’s smart to do them all at once along with a new chain. A little grease on the hub before installation makes future removal easier when maintenance time rolls around.
