Excavator Tracks Nelson

Excavator Tracks

Our Tracks are high quality, competitively priced Rubber tracks for Hitachi, Komatsu, Cat, Bobcat, Airman, IHI, Kubota, Takeeuchi, Sumitomo and Case excavators. The tracks are made using continuous steel cords, which means there are no joins or breaks, making them up to 60% stronger than joined steel corded tracks. They are also corrosion resistant ensuring they are more reliable in harsh conditions.

Rubber tracks offer a smoother and quieter ride and are more versatile. Steel tracks can damage hard surfaces, so unless you have rubber pads, rubber tracks are a better option, especially on concrete and asphalt.
