I've heard of people bolting rubber mud flaps to the fan to really close up the tolerance. I've never checked mine. For me, all that really matters is to get he snow off the driveway.Many differences here. The main one is probably the diameter of the blower. I expect his is a 27" giving a higher tip speed. Snow density is always a factor. HP when you can really load the snow into the blower makes it throw further. He has a beautiful setup there. Not a typical homeowner. Truthfully blowing distance is usually a bragging rite. If your does not blow well check the tolerance on the fan wall. The side going up to the discharge. Too much distance and you cannot blow slush. Back in the day of silage blowing they always told us for good performance to pick up a nickel and leave a dime. That is the proper clearance.
My driveway is 3,000'.
Snow blower is a MK Martin 72" inverted.
Tractor is a TYM T754 gear drive.
Two big hills that sometimes give me trouble getting up. I'm working on rerouting one of those.
