Rmart30,
Yanmar has also made great tractors since 2006 (in the U.S.).
A Yanmar advantage is that virtually any territory in the U.S. is familiar with Yanmar engines and their durability. If you mention Kawasaki engines - they are good - but not Yanmar level. And Kohler, Briggs, and Tecumseh lower still.
Other names like Kubota, Iseki, Subaru, and Yamaha are great engines - but not known as much for their engines as are Yanmar. And of course there are Honda engines.
My point is - when people can identify with millions of engines - they identify with levels of quality. So selling Yanmar tractors has an edge.
And I agree with you - a dealership without a service department is tough because a tractor is a longer term investment than is a car or truck. You want a product that can be worked on.
In our area there are sporadic Yanmar dealerships - but expanding. Certainly more Yanmar than Kioti or Branson or TYM (once Cabelas quit) or LS.
But the OP stated no service department - so I'm not sure what brand choices exist that don't require a service department - at least not legitimate dealers because who does warranty work ?
