Product Details

This is the replacement aftermarket tension idler wheel for the John Deere 50D mini excavator serial number up to 274999. 

This is the large idler wheel on the opposite end of the undercarriage from the sprocket. Idlers guid the track in and out of the track rollers and provide a way to control track slack and tension.

If your serial number is 275000 and up, you will need a different part number.  If you are unsure, please call us to verify measurements. This idler comes with a protective guard to keep debris from passing through the idler wheel and causing extensive damage to the rubber track.
