Kubota KX61-2 Lower Track Roller

Aftermarket OEM Replacement – Part #RD101-99900 / RD301-99900

Maintain reliable undercarriage performance on your Kubota KX61-2 with this aftermarket lower track roller from United Skid Tracks. Bottom rollers support the weight of the machine during travel and digging while guiding the track for smooth and consistent operation.

The RD101-99900 bottom roller is a direct replacement for several Kubota OEM part numbers and covers a wide range of previous-generation -2 series mini excavators. This makes it a versatile solution when servicing older Kubota models.

Bottom rollers are sold individually. For best results, it is recommended to replace all worn bottom rollers at the same time. Installing new rollers alongside heavily worn components can lead to uneven load distribution and reduced service life.

This roller is known to be interchangeable with part numbers RC101-21803 and RD301-99900 and is designed for proper fit and dependable performance.

Alternate Kubota Part Numbers:
RD101-99900, RD301-99900, RC101-21803, RC101-21800, RD101-21902, RC301-21902

United Skid Tracks carries a full selection of undercarriage components, including bottom rollers, rubber tracks, and sprockets, to keep your Kubota KX61-2 operating efficiently on the jobsite.
