Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

This is a new 88835, used about 4 times and I was recently clearing snow off my back patio that has 2 x 2 slate stonework.  The machine hit an edge on one of the stones and it chewed it up, taking about 1/4 of the stone.  Following that, when engaging the auger and impeller there a relatively loud banging noise.  The shear pins are intact, so I'm looking for ideas on what is causing the noise.  Bent auger blades or something else?  Thanks.

can you disengage the transmission and rotate the auger to see if it's the auger hitting something?

This is where you hope the shear pin snaps instead of breaking the auger, shaft or transmission.   Perhaps the auger shaft was bent?

No, I haven't tried that yet, but will give it a try tonight.  Big storm heading my way, so hopefully I get it sorted. 

Wanted to post that I found the problem.  The stone bent one of the auger blades and I was able to bend it back by hand.  The noise is gone.  Will keep an eye on throughout the rest of the season and may replace that blade if necessary.
