For, me, on my
BX2670, less time for the blower than the mower, but longer than either was on my Wheel Horses.......
As some mentioned, a lot might have to do with which model of tractor, which model of blower, and whether the friends brought beer or not.
Personally, the front mount snow blower is the ONLY way to go. No matter how deep or far through the drift is, you just keep going, and never have to go 10 times farther to make sure there is room for next time like you have to do with a front blade. I wait for the storm to end, don't go out in the middle of a blizzard because I'm afraid of not being able to push through. No backing up like a front loader that can't be pushed through because the snow is too deep. With age and physical limitations, I don't have to twist around in the seat, which I can't do anyway, as a rear mount snowblower requires.
Now, if you like spending 4 times as long in the cold, if you like putting 4 times the hours on your equipment, if you like being twisted around in the seat, well, you might like one of the other methods better.
