Thumbs down Troubleshooting help Toro 521

I am a newbie and need troubleshooting help. While using 521 today I hit some dirt and rocks, heard what I thought at the time might be a shear pin snapping as blower stopped blowing. After melting all snow and ice out of blower, I cannot manually turn either the auger or the impeller. If it was a shear pin wouldn’t one or both of the auger blades spin easily? The shear pins both appear to be in place. The auger blades just rotate by hand a little bit in each direction. The impeller does not move at all. Am I in big trouble?

Check belts as you may have detonated a belt and it wrapped around things that a belt is not supposed to be around. As well it could have just jumped off and is binding between pulleys and housing or other things. Also check for rocks and dirt between the back of the impeller and the back of the blower housing. I have seen them wedge in there under load and lock it up tight.

Sounds like shear pin(s) to me...…

I've blown a few in my days and they always act like you describe.... The bolt, when sheered, "smears" it self when breaking. They do not snap clean at a 90* angle.

That "smear" makes it hard to turn. Just drive one out..you'll see.

Good luck man.

Welcome to the forum! It sounds like something (rock, etc) jammed in the impeller to me. Especially since you said the augers will wiggle a little, but the impeller won't move at all. If you'd just broken & smeared the shear pins, that wouldn't do anything to the augers.

I'd grab a flashlight and take a close look around the impeller. Something stuck between the blades and the housing is your best-case scenario. Something stuck "behind" the solid part of the impeller would be worse.

By all means, check the shear bolts. One way to see if they're still intact, without needing to remove them, is to put two wrenches on one shear bolt, and twist the wrench that's on the bolt head, and see if the other wrench wants to turn as well.

The belts are also worth checking, in case they jammed up the impeller pulley.

If you do find a jammed rock, I'd be inclined to try turning the impeller "backwards" to remove the rock, opposite the normal direction it spins during operation. You could use a piece of wood to push on the impeller.

Excellent suggestion-my 521 does this occasionally at the start of the season and will lock up like a bank vault.I have a 3 foot crowbar I keep next to the garage door that I stick down through the shute to knock the impeller in whatever direction necessary to free the stone.There's quite a gap between the impeller and housing,but the thing throws wet snow so well,I've never seen the need to put an impeller kit on it.

Thanks for all of the replies. I will try all of them tomorrow morning.

My model is 38052, serial # 6906856. Original owner, so this puppy owes me nothing!

If the shear pins smeared what is the secret to getting them out?

thank you for the model information,
as normal for most all toro's your model fails to use auger shear bolts like on the other brands.toro uses a way stronger steel geared auger gear box. for the auger, in place of auger shear bolts it uses the grade 5 bolt with a locking nut, the part number is 321-10 for the bolt and 3296- 10 for the nut, something one can get in any hardware store as a 5/16 x 1 and 7/8 long
here's a link to toro's website were you can find the information and download your shop manual
https://www.torodealer.com/en-us/Pag...ts-lookup-tabs


as to why it stopped i would carefully look in the impeler area to see if you have something left stuck in there ,as thats a big reason i have gotten many a toro traded in to the poe shop i work at. one time it was a paving stone. good luck,my bet is on a rock stuck deep in the impeller area

heres a shot of the bolt toro uses in your model and others, as can be seen it a normal grade 5 bolt
