I have a Rad 62" front mount on the bota 3830 cause that is who makes Kutoba's blowers. I like mine but I have never had any other so I have nothing to compare it with.
I have the Blizzard 64" 3pth blower & I think it is pretty well made. I've seen others that look a little rough in finish & paint quality. This is my first winter using it & so far I've been very satisfied. I like the crank for the chute better than the cable system I've seen on others.
I had a rad 48" blower for my exmark commercial mower. It was a good piece of equipment. It chewed through the snow nicely. Even found a metal shovel in a snowbank and it chewed it up and sent it through. Two drawbacks: The chute was slow to spin from one side to the other and you had to walk around to the chute to change the discharge height.
