72" Front Mount Snowblower
I seem to have an issue with sheer pins sheering. The size and weight if this thing, I would think it pretty much bullet proof but so far this year I've sheered three pins on the auger and one on the drive shaft. Anyone else experience this? I plan to replace them all with a grade stronger.
Re: 72" Front Mount Snowblower
Can't say about front mount blowers as I have a 72" ECONOR (by NORMAND) driven by about 30hp at the PTO. When I lose the pto shaft pin, usually because fan can not clear as fast as auger puts snow into chute. Mainly happens to me when I have too high a ground speed or flap on top of chute restricts discharge too much. My auger pin goes when I hit something in/under the snow. I only ever use plated, 1/4" x 20 bolts because they are way cheaper than anything else (I buy them by the pound at TSC), easy to change and have faith they will protect the expensive bits. I use my blower on many driveways as well as on my maple syrup trails and firewood trails, and I break lots of pins.
Re: 72" Front Mount Snowblower
What kind of noise do you hear when they break ? Sticks , rocks , chunks of frozen dirt , ice , make an impeller very unhappy . How hard is the snow that auger is trying to move ?How many hours of use are we talking about ? Are thay roll pins or bolts ? Pins will wiggle out , tight bolts are better . Just trying to help , Kevin .

Same blower has you
Had the same trouble, now using gradec 3
I also have trouble with the back chain and sproket, they keep falling off.... Keep an eye on your chain and sproket, remove the cover, and do a visual
Re: 72" Front Mount Snowblower
At the time I lose the shaft bind typically in light of the fact that fan cannot clear as quick as twist drill puts snow into chute. Fundamentally befalls me when I have too heightened a ground speed or fold on highest point of chute limits release excessively. My wood screw pin goes when I hit something in/under the snow.

Anyone face this sort of issue?
