</font><font color="blue" class="small">( <font color="blue"> I also had misgivings about JD because many of their tractors are built by Yanmar. I don't know anything about Yanmar, they may be a fine machine, but I wonder why JD doesn't build their own tractors in the subcompact class. I figure I might as well buy a Yanmar for less money rather than pay JD for their name and get a Yanmar. </font> )</font>
Thats not completely true.
The JD 4000/4010 series these tractors have Yamnar engines,which are very good engines,but the rest of the tractor is not a Yamnar product,except from my understanding the small John Deere 4100.The JD 4200/ 4210 through 4700/4710 are assembled in Augusta Georgia with a Yamnar engine.
The new JD 4020 series have John Deere power tech engines.
With that being said,Kubota makes an excellent product.
