Sorry Glagen - I'm not a real good mechanic - fact is I'm a horrible mechanic. We do have some JD Mechanical Whiz Kids on here though who may be able to answer that.
For what it's worth, My opinion is this - I wouldn't let the snow blower drive your tractor purchase... sell it! Get the unit you want. If you're thinking 4x10 and a 47 or 48 BH then I'd think long and hard about it. In the long run the $$ diff will fade, but you'll be happy you got what you wanted. I never push my brand or model on anyone - but I can say without hesitation that I am thrilled with the 4310 and what that little beastie can do. I think I push mine beyond it's intended limits, and yet it hasn't let me down yet.
Certainly it's your call though - I wish you the best of luck whatever you get.
