Description

If you’ve got chain drive systems on your planters, cultivators, or other farm equipment, you know how important it is to keep that chain running straight and at the right tension. When an idler sprocket starts to wear out, the chain can jump, bind up, or wear prematurely—none of which you need when you’re trying to get crops in the ground or worked. This 17-tooth idler sprocket gets your #40 chain system running smooth again.

What You’re Getting

Precisely machined 17 teeth that mesh perfectly with #40 roller chain
5/8 inch bore that fits standard shafts and mounting hardware
Heat-treated construction that stands up to the constant motion and load cycles
Smooth operation that reduces chain wear and keeps your equipment running efficiently

Built for Real Farm Work

This idler sprocket is designed for the chain drive systems you’ll find on planters, cultivators, spreaders, and other equipment where #40 chain is used to transfer power or maintain proper chain routing. It’s the same type of sprocket used on John Deere planters and drills, so you know it’s built to handle the demands of fieldwork.

Made to Last

Farm equipment doesn’t get babied, and neither do the parts on it. This sprocket is made from quality steel that’s heat-treated to handle the stress of chain engagement cycle after cycle. The teeth are cut to precise tolerances so the chain seats properly and wears evenly, giving you reliable service season after season.

Good to Know

Installation is straightforward—just slide it onto your 5/8 inch shaft and secure it in place. Before you install the new sprocket, it’s a good time to check your chain for wear, proper lubrication, and correct tension. A worn chain will chew up a new sprocket pretty quickly, so replace both if the chain’s showing signs of stretch or wear.
