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.
If the tractor you are referring to is the MT180D in your signature, it is a SCUT not a CUT. I believe my L6060 is a CUT and it performs very well in all snow conditions but I am also set up for it. See the pic below. I can plow with an 8' wide FEL mount plow
up 15% grades and did that yesterday. I used the inverted blower to go down the 1 mile long driveway, except for the last 400' or so where the neighbor has screwed up the driveway. I will not use my blower there. I did it once last year and it sucked up a bunch of rocks and loose asphalt. That section is about 15% and I plow down and back up several times. The rest of the driveway gets the blower treatment, with the side plates removed and for the areas around the house and other buildings, I use the front mount plow with the wings attached. Then I use the plow as a pusher.
As someone pointed out earlier, in this thread, we all have different conditions and needs. For those in the prairies that experience drifting snow, those who regularly get more than 2' snowfalls or those who get very little snow in a season, I doubt an inverted blower would be useful or worth the extra cost vs a rear facing blower. For drifts and big snowfalls a front blower or just a plow may be the best solution. If it wasn't for the fact that I don't have enough room beside my driveway to plow large accumulations of snow, I would use the plow exclusively. However for MY conditions, I need a plow or pusher for areas around the buildings. I tried using a snow bucket but quickly ran out of room to stockpile snow and found it to be too slow. A plow or pusher compacts the snow as you push it, the snow can be piled higher and it's faster because the bucket doesn't need to be dumped. Last year I had 5 piles of snow that had been pushed (therefore compacted). Those piles ranged in size from; 30' diameter x 10' high to 50' wide x 30' deep and 10' high. Even at that I ran out of storage and had to cut down one the piles to make room for more snow.
My driveway used to get plowed until it got so narrow I couldn't get the pick up truck out. Then I had to blow the snow and used a rear facing blower, backing up for 2 miles and looking over my shoulder. I had enough of that and got the inverted. Now I blow the driveway whenever there is a build up of snow. I simply drop the blower and have a leisurely drive down and back up. No more sore neck for days afterwards. Much better, for MY conditions. I live in the mountains and don't get drifting snow and rarely get snowfalls of more than 2', usually more like 6" to 18".
