Jazzdaddy:
I have no problem at all moving one ton pallets with the 1251/M9, matter of fact, just got in from setting a ton pallet of wood pellets next to the deck for my wife. Cycle time wise, the 1251 seems a bit faster than the loader that I had on the 5030. The 105/125 have the self leveling loader which the M9 don't have but I run the 105 and either loader works fine for me. Spec wise, I'm not concerned with breakout force, thats a relative term anyway. Leverage on the bucket lip against an immovable object can be multiplied many times just by a slight movement of the tractor itself. Again, I'd like to have had the corner post mounted exhaust, but all the tractors I have run had a centered pipe so it's no problem, I just ignore it.
I might add that the ton pallet was moved and placed next to the deck in 2WD. I have only used FWA 2 times, once for the Chevy and once dragging a 40 yard roll-off container to the road (I do fabrication work on roll-off's on the side).
If I can pick up a 3/4 ton Chevy and lift it off a rock, that's pretty impressive to me.
Be sure whatever model you get to specify cast wheel centers on the back that way, the loader won't lift the back of the tractor as Kubota's loaders in general will float the tractor that they are on if that unit has stamped centers on the rear.
The 125X as far as my opinion is, way too much glitz without the glitter. That is, it's set up as a row crop tractor but it lacks the electronic controls that JD has on their tractors in that class like headland monitors. I don't row crop anyway so the X is too frivilous anyway.
The M9 has been around for quite a few years. It's proven itself and it's reliable. Kubota's foray into the middleweight market is spearheaded by the 105-125 and that's a hard market to get into.
