This is the replacement aftermarket tension idler wheel for the John Deere 50D and Hitachi ZX50U-2 mini excavator serial number up to 274999.


This is the large idler wheel on the opposite end of the undercarriage from the sprocket. Idlers 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.
