I knew a contractor that used rear pull blowers. All his clients were in suburban areas and were side by side, like 20-30 on a given street.
Also he only had 80+ hp tractors so weight was on his side for deeper snows.
He owned a bunch and also leased many for the winter season as farmers also leased for the summertime.
Back up to the client's garage, drive out blowing and go the next client, and repeat.
Unfortunately claims and insurance premiums got the better of him so he is no longer blowing snow.
Being a CUT owner I'll state that rear pulls would not be very practical mainly due to lack of weight, especially when you have wet 'snowman' snow or snow deeper than your clearance.
