When I looked almost six years ago at buying a new 50-60hp tractor, I looked at JD, Kubota and Kioti. JD was too far away and expressed zero interest in me, did not even return phone calls. Kioti dealer was closest, but tiny, a working farmer also selling tractors. They had five tractors in their lot. Kubota had close to 50. I'm sure this has changed a lot in the past years, but the local Kioti dealer near me now only has about 8 tractors in their front yard. Frankly it looks deserted...
Ultimately I went with Kubota due to confidence level in their whole package, the machine, the insurance, the dealer and how well I was treated.
Today I would look at LS and Kioti a lot harder before buying another new tractor, which I have no plans for. I expect my Kubota to outlast me, as I expect my made in India Massey also to do.
I think tractors have gotten like pickup trucks...they have gotten so good and so capable we seem to quibble over minor differences.
As long as you don't get a lemon, most folks are thrilled to death with their new tractors.
