Let me add a piece of hard-won, $$$ knowledge here.
I have my father's MF 250 that was originally fitted with a 232 loader when it was bought in the middle '80s. My son has established himself as "The Breaker of Tractors" with the MF 250 fitted with the 232. We are still trying to find time to split the tractor a second time to fit the 2nd transmission housing. The way the FEL's mount on these puts a lot of stress on that transmission housing.
Again, the 250 w/232 survived many years before my son broke it twice, but he struggles with common sense (life-long painful story), and the cast iron housing does not forgive. Yes to operator error, but with some minor fabricating skill of my own (and lots of observation of new FEL mounting designs), the design of the mounts and plates is marginal at best. Once ANY of those mounting bolts are loose, it's over. Again, before I get flamed about operator error, simply watching a neighbor with his 35hp Kubota TLB move horse manure vs my 250 with the 232 FEL, he was easily moving the same pile in 45 minutes that normally took me 2+ hours.
I do want to keep the tractor because it was my dad's, but IF I could do it all over, or was not attached to a particular tractor, I would look to a tractor with the more modern mounting designs with heavy sub-frames to the rear for FEL work, and 4x4 grunt to push the loader into the piles.
