Description
When your baler’s pickup starts missing hay or the drive chain jumps, a worn starter roller sprocket is often the culprit. This critical sprocket initiates the drive system that powers your baler’s pickup mechanism, and when it wears down those 20 teeth or develops play in that hex bore, you’ll notice it in reduced pickup efficiency and potential chain problems. Getting back to clean, efficient baling starts with this replacement sprocket.
What You’re Getting
- Precision 20-tooth design that matches your original equipment specifications perfectly
- Heavy-duty construction built to handle the continuous power transfer of baler operations
- 1-1/2 inch hex bore provides secure, no-slip connection to your drive shaft
- Compatible with standard #60 chain for reliable power transmission
- Direct replacement that installs without modifications or special tools
Built for Real Farm Work
This starter roller sprocket fits John Deere’s popular mid-range round balers including the 330, 335, 375, 385, 430, 435, 530, and 535 models that are the workhorses of hay operations across the country. Whether you’re baling first-cutting alfalfa, putting up grass hay, or handling custom baling jobs, these balers need their drive systems running smoothly to maintain the pickup efficiency and bale quality you count on.
Made to Last
Baler drive components take a beating from the constant power transmission, dust, and debris that comes with field operations. This AgSmart replacement sprocket is built with quality materials that resist wear from chain contact and provide reliable service season after season. The precise tooth profile ensures smooth chain engagement and reduces the vibration that can damage other drive components.
Good to Know
Installation is straightforward – the hex bore slides right onto your drive shaft with no special alignment needed. While you’ve got the cover off, it’s a good time to check your drive chain for wear and proper tension. A new sprocket works best with a chain that’s in good condition, so consider replacing both if your chain shows signs of stretching or wear.
