Here is one more argument to get a good front mount blower: better to have your dollars tied up in a good piece of equipment that goes with your tractor. Like money in the bank, and safer than the stock market.
Life is too short and it sounds like calling in and saying you are snowed in is not an option.
I take the mower off mine in the fall, put the snow blower on, and in the two winters we've had since I got it, have only had about 6 really deep snowfalls, but before I got it we had two killer winters and you could have skied on the snow pile I created in my back yard. It would take 2 days to clean up my farm yard, and that was with neighbor plowing my drive with his truck. So no telling what this winter will bring.
I decided I'd like to enjoy my little farm and the winter shoveling was getting old so the B2650 with a cab and front blower was a treat. The older I get the more important good visibility is to me. You will probably want to consider Rops lights next
