John Deere designs and builds all the compact tractors in Georgia. They are no longer just Yanmar clones. We know they use Yanmar engines still (the cost to build a Tier IV engine from scratch would be astronomical and not cost effective so they are stuck using Yanmar which is a great engine)
Kubota designs and builds their own engines AND puts them in their own tractors. Clearly it IS possible. I suspect that being the CUT market leader is why this is possible.
