Bob,
I know that is incorrect. The John Deere 4100 was made in Japan and the 4200 through 4700 were assembled in Augusta Georgia and had Yamnar engines in them. Some of the newer John Deere compacts have John Deere Power Tech engines in them (At the moment I am not sure which ones /forums/images/graemlins/confused.gif) I know Yamnar use to make some of the older compacts for John Deere and to my understanding Yamnar quit selling their tractors in the states with the Yamnar badge on them due to an agreement with John Deere because of John Deere buying Yamnar engines. I have a John Deere 4400 and it has the Yamnar engine in it and I am very impressed with the Yamnar engine. John Deere definately made the right choice of buying Yamnars,not saying the Kubotas and Izuzu are bad engines either. Does Honda make a diesel engine ??
