Kubota U45-ST

The Kubota U45-ST mini excavator utilizes the same rubber tracks and undercarriage parts as many of the previous generation models. Read the product descriptions for each undercarriage part carefully for your exact model when ordering online. Some parts are very specific and only fit certain serial breaks so always read and verify your exact model and which parts you need before ordering online.

Upgrade your Kubota U45-ST rubber tracks to the premium aftermarket rubber tracks from Rubbertrax and increase the lifespan and performance of your undercarriage. We now supply the complete line of U45-ST series undercarriage parts including the drive sprocket (RD546-14430), the idler (RD411-22307), the top carrier roller (RD461-21900) and the bottom track rollers down the center of the undercarriage (RD441-21702). We also stock the replacement RP851-22310 rubber tracks for your U45-ST. The Kubota U45-ST requires the 400 x 72.5 x 74 heavy-duty rubber track.
