My B2650 snow combo is a B2782B 63" front mount blower w/hydraulic chute rotation, and BB1560 60" box scraper in back.
Last late winter I cleared a winter's worth of snow from a neighbor's 800ft gravel driveway, 10 ft wide, in about one hour. The snow was compacted and drifted up to about 2 ft. deep, but kept her in low, and that snow lands 20-50 ft away, NO snow banks, ONE pass.
If just a few inches of snowfall, I run in Mid range and can often fly along at nearly full speed and that blower hardly notices. This is a FAST clearing system. Love it!
I used to run my 12hp 30" walk behind blower for hours, drenched in sweat, to clear our 300ft driveway, now done in less than half the time, NO sweat, and I'd swear this tractor consumes about the same fuel amount, if not less!
The 63" width totally clears the tractor wheel path, I'm glad I went with that size. The tractor powers it easily.
Box scraper is useful for tight space cleanup, and as a good counterbalance for the blower. I have industrial tires only, without chains, and in 4WD have very little problem with traction.
