Note the K guide guide-lug type — other guide types won't seat correctly on the rollers. Always confirm against your current track or the machine's spec plate, since some units shipped with more than one option.\u003c\/p\u003e\u003ch3\u003eWill this track fit my Kubota KX040-4?\u003c\/h3\u003e\u003cp\u003eYes — this track is matched to the Kubota KX040-4 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.\u003c\/p\u003e\u003ch3\u003eHow long do Kubota KX040-4 rubber tracks last?\u003c\/h3\u003e\u003cp\u003eMost rubber tracks last 1,200–1,600 operating hours depending on terrain, alignment, and tension.
