RC788-21700 Bottom Roller Assembly

The RC788-21700 dual flange bottom roller originally used on the KX033-4 is now the replacement roller for the Kubota U35-3 and U35-4 series. This is the aftermarket replacement bottom roller for Kubota U35-3 and U35-4 mini excavators so please verify your specific series for your model prior to ordering online.


The bottom rollers support and guide the machine on the track and carry the weight of the machine while it is traveling or digging. Operating with a busted bottom roller can do significant damage to the rubber track, so change damaged bottom rollers right away to prevent costly repairs.


Kubota bottom rollers are sold individually, but we always encourage changing all worn bottom rollers at the same time to maximize the lifespan of the undercarriage.


We also sell the rubber tracks and top rollers for the Kubota U35-4.
