  • Endless high-tensile cables — single-cure construction with no weak splice point.
  • Continuous steel cord — up to 40% stronger than typical aftermarket tracks, resisting stretch and de-tracking.
  • Precision OEM alignment — a reinforced roller path keeps running smooth and vibration low.

Frequently Asked Questions

Common questions about rubber track replacement

What size rubber track does the Kubota KX121-3 use?
The Kubota KX121-3 uses a 350x54.5Nx86 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 KX121-3?
Yes — this track is matched to the Kubota KX121-3 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.
Are these OEM or aftermarket Kubota KX121-3 tracks?
OEM-grade aftermarket tracks built to factory fitment for the Kubota KX121-3 — same dimensions and guide type, continuous steel-cord belt, at a better price than dealer OEM.
Directional or block tread — which should I run?
For mixed dirt and gravel, most Kubota KX121-3 owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
What warranty comes with Kubota KX121-3 tracks?
Our rubber tracks carry a 24-month warranty against manufacturing defects, with continuous steel cords and wear-resistant compounds. Technicians by trade; heavy duty comes standard.
