That shop sells spare parts for mowers, string trimmers, and chain saws. It specifically does not sell new, complete machines. It only sells the replaceable parts. I used shop=spare_parts as documented at <https://wiki.openstreetmap.org/wiki/Tag:shop%3Dspare_parts>. I could not find anything better. The Key:shop page accepts "user defined" values in the last row. Should I add spare_parts=mower tag?
