Direct Replacement Rubber Tracks for the Kubota KX121-2

Direct replacement rubber tracks for the Kubota KX121-2 are built for heavy-duty compact equipment applications where traction, stability, and uptime matter. These tracks are designed for dependable grip, smooth travel, and consistent performance across dirt, clay, gravel, demolition debris, utility work, grading, land clearing, excavation, and mixed jobsite terrain.

Heavy-Duty Construction for Daily Work

Premium virgin rubber compounds help resist tearing, chunking, cracking, dry rot, and premature tread wear under demanding field conditions. Continuous steel cord reinforcement adds internal strength, helps reduce stretching, and supports stable track performance through repeated turning, travel, and loading.

Built to Protect the Undercarriage System

A well-built rubber track helps improve machine control while limiting unnecessary stress on rollers, idlers, and sprockets. For contractors running Kubota equipment, that means better ride quality, stronger traction, less downtime, and better value over the life of the track.

Questions & Answers

What size rubber track does the Kubota KX121-2 use?
The Kubota KX121-2 uses a 350x54.5x86 rubber track. Always confirm against your current track or the machine's spec plate, since some units shipped with more than one option.
Will this track fit my Kubota KX121-2?
Yes — this track is matched to the Kubota KX121-2 by size and tread pattern. If your machine has a serial break or factory option, send the serial number and we'll verify fitment before shipping.
