I got tired of paying the high cost of Kubota filters for my ZD-221 so I went to Auto Zone and Advance Auto Parts looking for a match. Their employees were either too stupid or lazy to cross reference them, so I went to my local NAPA store. In 5 minutes I walked out with air, oil and fuel filters. Total savings were $37.00. The only filter I couldn't get was the hydro transmission filter. These have a check valve in them and are proprietary to the manufacturer.
