Kubota RX303 tracks — what size rubber tracks fit this machine?

Expert Answer

Kubota RX303 rubber tracks are commonly supplied in size 300x52.5x84. That means 300 mm track width, 52.5 mm pitch, and 84 links, which is the key fitment data to confirm before ordering.

For the best match, check the old track marking, measure the width across the inside of the track, then verify the pitch and link count. Also inspect the undercarriage for worn sprockets, idlers, and rollers, because badly worn components can shorten the life of new tracks or cause tracking issues. If your RX303 has a different configuration or aftermarket parts have been fitted before, use the machine serial number to confirm fitment. VANROCK supplies rubber tracks and other undercarriage parts for Kubota machines through its appointed dealer network, with pricing quoted on request.
