According to York's website, the MR2 series is good for cat 0 or cat 1 hitches on tractors up to 20 hp, so yes, at 17.7 pto hp on your BX2350, it looks to be a good fit. Weight of the MR25 is 132#. HTH
/ Will a modern implements MR25 york rake work with a Kubota BX2350?
A 5' rake is what you want for a BX. You should measure your lift arm height with the 3 point hitch all the way down which I think is around 8 or 9 inches then measure the implement. I have seen some implement that the 3PH will just barely go low enough to hook up to. When you run over a bump the implement will come off the ground. I would consider a rake for a Compact. I have a Woods LR72, it is a little big for the BX but it lifts it pretty good. It will try to drag in some places that are real uneven. If you go with a rake designed for a compact and you get a larger tractor it will work.
