I've noticed a few things about TYM; to start, they're capable of building a solid tractor. A lot of TYM built Mahindra owners are on this forum with a lot of positive things to say, particularly regarding comfort and ergonomics. There are a lot of happy TYM owners as well, yet you see a fair number of negatives too. Those really seem to come down to the dealer; poor dealer prep, poor dealer support, things of that nature. Now I'm not saying there aren't negatives to all brands, but you can look through the threads on here and learn a lot. The biggest thing is that TYM has both improved consistently over the years, and they just acquired Kukji, the parent company of Branson. Kukje builds solid machines, and they just built a big facility in Georgia. So I would think over the next decade you'll see a lot better support from TYM.
The Massey Ferguson GC is just an excellent machine, and has been since it was introduced. It's up there with the Deere 1R and Kubota BX, and parts availability shouldn't be an issue as they sell so many of them.
The new Kioti CS20 series subcompacts are really nice, they really designed it to fix the weak points of the CS10. Kioti has impressed me enough that I just purchased CK2610, so I'm a little biased, but not too much.
