Dave,
Here's one in Minerva. Have no idea on his parts support though. <A target="_blank" HREF=http://members.tripod.com/mts_no1tractors/index.htm>MTS No.1 Tractors</A>
This is off Yanmars site, have no idea how reliable it is though. <A target="_blank" HREF=http://www.yanmar.com/dealers/tractor/oh.html>Yanmar Dealers</A>
Now........why do they have to be close? Many of our respected dealers are here on TBN and will ship parts to you very quick.
Just a thought /w3tcompact/icons/grin.gif
