    Frequently Asked Questions

    Fitment, availability, fulfillment, and support for this product

    What bottom roller / track roller fits the Kubota U45-3?
    This bottom roller / track roller is listed for the Kubota U45-3 and matches OEM Part #RD411-21700. Before ordering, compare your machine make, model, serial number, and existing part number to confirm the correct undercarriage position and fitment.
    What sprocket fits the Kubota U45-3?
    Matching drive sprocket options for the Kubota U45-3 include Kubota U45-3 Sprocket | Part #RD411-14432. When installing new rubber tracks, inspect sprockets for hooked, sharp, or uneven teeth because worn sprockets can shorten track life and damage the drive lugs.
    What front idler fits the Kubota U45-3?
    Matching front idler options for the Kubota U45-3 include Kubota U45-3 Front Idler | Part #RD411-22303. Front idlers guide the track and help maintain proper tension, so inspect the flange, bearing condition, and wear surface before installing new tracks.
    What top roller fits the Kubota U45-3?
    Matching top roller options for the Kubota U45-3 include Kubota U45-3 Carrier Roller | Part #4392416. Top rollers support the upper track path and should be checked for bearing play, flat spots, and uneven wear during undercarriage service.
    Should I inspect the full undercarriage before replacing this Kubota U45-3 part?
    Yes. Sprockets, idlers, rollers, and rubber tracks wear together as a system. Before replacing this part for the Kubota U45-3, inspect the full undercarriage for uneven wear, bearing play, hooked sprocket teeth, and track tension issues.
    How do I confirm this product fits the Kubota U45-3?
    Confirm fitment by checking your machine make, model, serial number, and existing track size or OEM part number. For rubber tracks, verify width, pitch, and link count. For undercarriage parts, compare the part number, bolt pattern, tooth count, and machine position. You can also use the TrackTECH Track Finder or call (850) 816-7898 before ordering.
