I use a pull behind for the bulk of my clearing, and love it. For me its the best way by far to clear my 6/10 mile road and my neighbors odd shaped drives. I even like it better than a previous front blower.
In this case I would have 2 areas of concern, hp and weight. It looks like he only has 19 pto hp and tractor is relatively small for a heavy rear implement hanging off the back. Generally speaking you usually see inverted blowers on larger tractors and as a result there are not many smaller blowers on the market, I just did some looking and found 2- 60 in ( erskine and lucknow) and 2 68in (normand and mk martin)
Of those i am guessing the erskine might be the easiest to get in the mid-atlantic but it is pretty heavy-840 lbs - that might easily cause steering issues on snow unless you put a fair amount of weight in front. The lucknow is almost 300 lbs lighter and has a bigger fan (22 vs 20 inches) but i am guessing they might be a bit hard to come by
if they go up to the 68 in blowers they then can clear a 10ft swath in one up and back but might have to go a bit slower. Can't seem to find a weight on the meteor but the normand is about the same as the lucknow.
As far as use an inverted works great on a 4-6 inch snow, where there could be an issue is if you get a noreaster and don't clear during the storm- an inverted blower needs you to be able to drive the tractor through the snow- if you can't drive through it you are bucketing or backing up and going forward repetitively. On that small a tractor i don't think the lift height would be enough to really enable the second method.
Not sure if the drive is paved- that really helps with any blower in an area with marginal temps as you may not get to build an ice layer to protect the gravel. One of the things i like about my pull blower is that i use it for pretty much any time it snows, even quite small ones, if i waited for a big snow like most do with a rear push i would not see the value as much.
hope this helps
