I have the bigger B2782 on my
B3030, with hydraulic chute rotation and hydraulic deflector. We live in a snowbelt region, so we get "lots" of snow (not this year however). I found the blower works very well. 6" of snow is nothing, 1' of dry snow it starts to work, but I can blow close to 2', going slow that is. As for wet stuff, I had no problems - a foot of really wet heavy snow could be done, but you'll be going slow. I don't recall ever having the chute clog last year. When it's dry and light, it shoots snow a mile if you want. General rule of thumb is 5 pto hp for every foot of blower, and I believe the 3030 puts out 23 pto hp, so would the smaller 2781 handle more wet snow? sure, I guess it would, but for me I wouldn't go with the smaller unit. As Wally1 mentioned, the wider width will allow you get closer to objects, plus clear a path wider than your rear tires, specially when turning. Overall, I'm very pleased and would not change my set-up. I do highly recommend at least the hydraulic chute rotator, I can't imagine cranking that by hand everytime.
On a side note, I did have some issues with breaking the chain when I first got it. The chain tension assembly (reduction housing) is held tight with lightweight, thin plates and bolts. I made new heavier plates and used case hardened nuts and bolts - after that i've never even broken a shear bolt. However, I seemed to have been the only one that had trouble with the chain, so maybe it was an isolated case.
