I've got a Braber Equipment 50" blower for my tractor. I got it from Northern Tool. I have had it for about 6 years now and it has been through a lot. I change out the gearbox oil every other year and it keeps on chugging. It works great for how much I paid for it.
I have blown snow twice the height of the blower and it has hardly any effect on the tractor. It'll blow through anything. One day we had about 2 feet of fresh powder, and my neighbors swore I was blowing it 150'.
I keep thinking of putting an electric motor to rotate the chute, but it doesn't bother me too much to rotate it. Maybe one summertime project.
