I am using a B 2781 A blower on my 2620 and really love the way it cuts thru everything. I had a B2200 with the cheaper 50" blower and while it was effective it was on the light side and did not have the same quality of skid shoes, auger, cutting edge, and fan that the 2781 has. The 2781 is, in my opinion, well worth the extra $$. One thing you will note is that the drive shaft is not centered on the unit which looks different but works extremely well. I know this is the kiss of death but usually by this time on the old blower I would have gone thru a few shear bolts by now.....on the 2781 I have not sheared anything YET! Guess I better be ready to change a few bolts during the next storm.
