Hitachi ZX60USB-3 and ZX60USB-5 sub series mini excavator models utilize the same rubber track size. Rubbertrax stocks replacement rubber tracks and some undercarriage parts for the Hitachi compact mini excavators designed for the North American construction market. This category is for the Hitachi ZX60USB-3 and ZX60USB-5 series models. The undercarriage parts may vary per sub model so please verify prior to ordering. If your Hitachi is equipped with steel tracks we have several types of replacement rubber pads that would attach to your existing track group.
