This page is dedicated to the Kubota mini excavators and SVL compact track loaders that Rubbertrax Inc. spends special attention to. Many rubber track companies don't bother with the Kubota line, and very few carry the undercarriage parts for Kubota. Rubbertrax carrys many of the Kubota KX series mini excavator undercarriage parts including replacement drive sprockets, track rollers, tension idlers and even top carrier rollers. We carry several tracks that are dedicated to very specific Kubota mini excavators. These are tracks that do not interchange with any other machine and most smaller rubber track companies try to provide a track that seems to work, but in the long run the track will fall off, or wear prematurely becuase it is not designed to integrate with the carefully designed Kubota undercarriage system. See our individual Kubota mini excavator flyers: Kubota Mini Excavator Track and Parts Brochures

OEM C-Shaped Rubber Track Tread Pattern This is the "C-Pad" Tread Pattern common on Bobcat Type Compact Track Loaders, now available on most track loader options. The C pads are off-set for optimal smooth contact and operator comfort. This tread pattern gives you a balance between traction and floatation and operator comfort to prevent fatigue. This tread pattern is available for most track loaders including:

Kubota U35 Rubber Track Guide

In the case of the U-35 Kubota the tread pattern isn't the most important part, it's the guiding system. Many Kubota models have dedicated guiding systems. In this case you can see where our track on the left has the smooth outside guide type to reduce vibration as the operator drives. You can see a competitor's inferior generic track to the right with deep gaps on the outside of the guiding system which will cause a rough ride, and premature wear on the rollers and the tracks. In this case you get what you pay for and the cheaper guys don't have what you need for your Kubota.

  • Kubota KX 021, KX 024 Series
  • Kubota U-30 Series
