Which John Deere excavator models do these undercarriage parts fit?

Fitment can vary by model and serial number, so match the part number to your machine or confirm with our parts team before ordering.

What undercarriage parts wear out most often on a John Deere excavator?

Rollers and idlers are the components most commonly replaced during undercarriage work, since they carry constant load and ground contact. Track chains and sprockets also wear over time and are often replaced together during a full undercarriage rebuild. Broken Tractor carries all of these wear items for John Deere crawler excavators.

How do I know which undercarriage part is correct for my John Deere excavator?

The best way is to match the part number from your existing component to what Broken Tractor lists, since fitment can depend on the model and serial number. If you are unsure, our parts team can help confirm the correct undercarriage part for your machine at (800) 909-7060.

Can I replace just the rollers or idlers instead of the whole undercarriage?

Yes, rollers, idlers, sprockets, and track adjusters can be replaced individually as they wear. Many owners replace worn rollers and idlers first, then address chains and sprockets as needed. Broken Tractor offers these components separately so you can rebuild the undercarriage in stages.
