Our MST600VDL 500x100x76 tracks are manufactured under strict quality control procedures, and are guaranteed to fit your Morooka MST600VDL machine. Our tracks feature a single coated steel cord wrapped continuously around the rubber track belt, ensuring there are no weak points. Further, our Morooka MST600VDL are manufactured with twice as many lugs, so that every sprocket tooth grabs a lug instead of every other.
