Kennyd, I have searched online parts. the deck part # are different, but how different is the question. I already have the attaching hardware/linkage (draft arms, etc..), they came with my MMM kit.
mfreund, thanks. You didn't have to modify any of the connection points? From the pictures it looks like the yoke connection point on the deck (this is where the deck connects to the rockshaft lift arms) is taller on the 4610 decks. Since the yokes are adjustable, maybe this doesn't matter. Did the driveshaft work on the 4310? the part numbers are different in the parts book.
