RD101-99900 Bottom Rollers

The RD101-99900 is a direct replacement for several Kubota OEM part numbers, so this specific roller covers a wide range of the previous generation -2 series model mini excavators. This is the aftermarket replacement bottom roller for Kubota KX 61-2, 61-2SS, KX 121-2 (must verify serial), and KX 121-2SS mini excavators.


This roller fits the following models:

  • Kubota KX 61-2
  • Kubota KX 61-2 SS
  • Kubota KX 71-2
  • Kubota KX 91-2
  • Kubota KX 121-2 (must verify serial number)
  • Kubota KX 121-2 SS
  • Kubota RX 302

 


The bottom rollers support and guide the machine on the track and carry the weight of the machine while it is traveling or digging.


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