Description

When your baler’s pickup drive starts making noise or your chains are jumping, it’s often this critical sprocket that’s worn out. This double idler sprocket keeps the #50 chain properly tensioned and running smooth in your John Deere baler’s pickup mechanism. A worn sprocket doesn’t just make noise—it can damage expensive chains and leave you stranded in the middle of hay season.

What You’re Getting

Double sprocket design with 40 and 22 teeth for precise chain alignment
1-inch hex bore fits directly onto your baler’s pickup drive shaft
Hardened steel construction handles the constant rotation of hay pickup operations
Direct replacement for original equipment—no modifications needed

Built for Real Farm Work

This sprocket is engineered for John Deere’s 400 and 500 series round balers that see serious hay-making duty. Whether you’re baling first cutting alfalfa or picking up windrows in challenging conditions, this is the same quality component that came on your baler from the factory.

Made to Last

Baler components take abuse from dirt, crop residue, and the constant vibration of field operations. This sprocket’s heat-treated steel teeth resist wear and maintain proper chain engagement even after thousands of bales. The precision-machined hex bore ensures a tight fit that won’t slip under load.

Installation Notes

The 1-inch hex bore slides right onto your pickup drive shaft—just remove the old sprocket and install the new one. Make sure to check your chain tension after installation, as a new sprocket might require slight adjustment. It’s also a good time to inspect your pickup drive chains for wear while you’ve got things apart.
