Hi keeny,
I would suggest keeping your front mount and adding a Rear blade in the back. You then should be thinking cab !!
I understand the "In your face" blower dilema...I have a Cub cadet 3204 garden tractor w/ a 45" blower. The wind gets ya no matter what, so get the cab if its too much. The machine performed beyond all my expectations. I can deal with the cold, just wear a full snow suit, and if possible snowmoble helmet !!
Besides if you have a rear 3Pt blower, you now have to concern yourself with extra lighting for the back....and always looking backwards!
I also used my JD4100 (FEL and Rear Blade)...I only used my rear blade, it was so much quicker than the FEL !!
If you keep the Front Blower and add a Rear blade, you wont need the FEL for snow!!
Good luck either way!!
