My BX-22 was a real champ yesterday, too. I did not experience any catching of the bucket during the floating-scraping manuvers. I did manage to get stuck twice...worked it out by itself the first time, but the second required my pickup to pull it back. The front-end dropped off the end of my elderly neighbors parking area pavement and just bearly caught the front axle enough to "park it". The FEL was no help as the really big pile of snow under it didn't afford any leverage to lift the front of the machine.
I spend six hours on that machine yesterday doing the equivalent of about 500' of drveway between ours and the other two. We had about 22" plus drifting to deal with.
One other point...I'm really, really, really glad I had second thoughts and took the turf tires back and exchanged for bars. There was no way I would have been able to deal with this storm with turfs!
