Built for Australian construction, landscaping, and civil works, it's the ideal replacement for your Kubota U25-3 or U27-4, as well as a range of other mini excavators.

Our top rollers are engineered for longevity and performance. The forged steel roller body features a hardened wear surface to withstand harsh, abrasive ground conditions and high load cycles.

How to Confirm the Correct Top Roller: To ensure proper fitment, confirm your excavator’s make, model, and serial number, and where possible compare the existing roller’s dimensions (overall length, flange-to-flange distance, and shaft diameter) with our specifications before ordering. If you are unsure, contact us with a photo of your current roller and your machine ID plate and we can help match the correct part.
