As far as I can tell (may be 100% off here) the only Mitsubishi tractors sold now in the U.S. are branded Mahindra? Mitsubishi is another brand I did not consider as no dealers showed up anywhere near me (ditto Yanmar).
I asked the same question at the dealership a couple months ago and I was told there is one company selling Mitsu's. I did not know enough to counter the assertion and to this day i still don't know enough.
I do know that upwards of 2006, Farmtrac sold a Mitsu tractor under the Farmtrac label. Satoh was the other Mitsu tractor once sold here.
Mahindra as a corp, does not sell Tym. Tym has its own array of dealerships. I do not know if it is even allowed that a Mahindra dealership being able to sell Tym tractors on the same lot since Mahindra uses them to brand a line. I know of one Mahindra dealership that sold Kioti as well. That dealership eventually lost the Mahindra line for reasons beyond me.
It may very well be that Mitsu is exclusive to the Mahindra name presently.
What I have learned over the years doing this stuff is that there are many good tractor brands. There are two things to match: 1. how you use the tractor and 2. Substantiality of the dealership.
For instance, I log with my tractors. I used to own JD when they had their 50 series tractors. These were made by Yanmar and some of the finest tractors they ever put their name to.
When I discovered that JD had switched to plastic fenders, hood and floor boards, I shied away. When I further discovered that their gear cases were made of aluminum, that sealed the deal for me not to be involved with them.
Now for the average guy using a tractor, their 3033E or 3038E may be all the tractor one needs. Bringing a tractor into the woods is about as fast a method to beat up any tractor. The woods beat up logging skidders. Their present line of tractors i did not trust to stay together being made the way JD chose. Plus these cheapened tractors came with elevated pricing strategies.
With Kubota, it was about their trundle type foot control. I suppose anyone can get used to anything but I did not like this control method plus their lower line L series had the aggravating habit of placing its tie rods directly in front of the axle. That would have been tie rod pretzel time for me.
I believe you get the drift of choosing tractor to need. Buy anything whose proven dealership is close to you after that and I do mean "proven" meaning they are part of the landscape for many years.
Good luck in your endeavor.
