I had an MT125 TLB, great little tractor! I put in our new septic system, graded the site for a new cottage, did all the power and plumbing trenches, cut in the drive, etc.... it will do the jobs you are going to do, just not fast. I, too, had plenty of time, so that made it feasible. The little MT never let me down. 225 hours in 20 months.
I did end up selling it and purchased 2 sizes up, the LS XG3025 TLB (now MT225e). Much heavier, much bigger, more capable? Only in a couple of ways....1) the BH is definitely stronger. 2) The loader is definitely more stronger and the bucket is almost twice the size (so can carry more = more productive). Do I like the new tractor? ... absolutely! Do I miss the little 125? ... absolutely! They both have pros and cons.
If I were to be purchasing my first tractor all over again, and had to choose between these two, I would have to go with the larger XG3025, solely due to the greater capabilities. The only downfall with the MT225e is that it does not accept a MMM.
With that being said, the new 2020 Kioti CK2610 (similar size) can accept a 72 inch MMM. I do not know how much they will cost, but there is that option.
As said before many times on here, “ buy once, cry once”. Go sit on them, drive them, operate the controls, fit the tractor to you!
Good luck on your search! Do not hesitate to ask any more questions.
