Take 1 Auger stuck on shaft, add aircraft rivet gun vibrations, and...

... like magic it now spins freely on shaft.

A couple months a ago I picked up an otherwise nice Snapper 1030 (series 4) that had one auger stuck on the shaft.

I did the typical, soak in penetrating fluid, bang with hammer, etc... I then thought to myself, would high speed vibrations potentially break up the rust inside between the auger and the shaft?
I came across plenty of cases of mechanics using this method to free up rusted brake drums and the like.

Did a bit more research and found out the trigger on an aircraft rivet gun makes it much more controllable than an air hammer/chisel, so I picked one up on eBay and today after just a few minutes of hammering away at the auger, it began to move.
A few more minutes and I could move the the outside edge of the auger 6 inches.
Some back and forth movement by hand for a couple more minutes and now it spins freely.
Add a boat load of grease and a new shear pin and I'm done !!!

Yes, it did remove the paint, but I'll just smear some grease on those areas and deal with the paint next spring/summer.

Interesting solution.

I'm pretty much retired from the forum thing, but I check in every now and then.

I was actually quite surprised it worked so quickly, not to mention relieved.
I bought an old Chicago Pneumatic (many say the best made) 3x gun with regulator, spring retainer and 5 sets (bits are called sets).

Similar to this one and also shown is the set I used...

Thank you. I thought the rivet gun pulls the rivet pin out like what we use using hand rivet tool.
I have an Ariens ST824. The augers are rusted on to the shaft. Both sides of the shear bolts were snapped when I tried to remove them leaving the bolt body in the shaft. Impact hammer did not do anything to remove the bolts. I am leaving the augers the way they are hoping I don't hit anything hard when blowing snow. It is always in my mind trying to free the augers one day.

So i am assuming you hammered along the length of the auger sleeve back and forth to dislodge the rust between the sleeve and the shaft? I may have to try that out. My old 78 Ariens has one stuck auger and even chaining it to a tree and then to my truck could not get it seperated lol

You got it !
Hammered what I could reach, then pulled the starter rope while I held down the auger clutch lever to turn the auger to another position and repeat.
Not more than 60 seconds of hammering before I had to turn the auger.
Did that five or six times and it then finished up by hand.
Twenty minutes from start to finish.
I don't have any other blowers with stuck augers, but it sure beat tearing the thing apart and trying to press it out.

I was worried about the paint and initially put some duct tape on over the end of the set (bit), but it just cushioned the blow too much. I guess it needed the quick/sharp pops of metal on metal, so the paint damage (removal) was the price I had to pay.
Well worth it in my book.
