Deere 445 47 Blower gets clogged instantly!

Ok first snow of the winter here…other than our October storm…all set to use my 47 blower that I bought used over the summer for my 445. It gets clogged immediately right in that tunnel over the impeller into the chute. It can't take any snow, light / heavy, fast slow… I cleaned the chute literally over 10 times. I tried grease spray and no change. I can see the impeller turning with the auger. Motor is at full throttle, sounds normal to me….Help! Btw the Deere 160 single stage blower went through the snow like butter! lol

If its the wet heavy stuff, mine isn't great with it either. I push all into a pile and then start at it from pile. Works much better under huge load.. You have checked your three sheer pins? Is the fan below chute loaded with snow also? Is the motor govenor doing its job? I use cooking spray on my 47 and with more paint off the interior chute, the more cooking spray I may need to use. Again, all with the wet heavy 38 temp. slush. Mine works better with chute pointed to the right(less clogg). Sure sounds like a shear pin for the fan but you would know best. ???????????

Did you have someone watch the impeller while under load? If the pin is sheared it may spin, but as soon as it gets loaded it stops.

Thanks for the fast replies! This I can see, the auger keeps spinning while machine is clogged. I thought there are just shear pins on the auger? Someone did say they saw the auger spinning too. Where are all the shear pins?

They watched the auger, but didn't know to look at the impeller. Could it be the key is sheared? Where are all the shear pins?
There are shear plates in the shafts with small bolts through them. There are spare bolts on the back of the blower body.

I replaced mine today. Happen to have pics. See the gold plate? It has a hole in it the white dot filled with snow. It lines up with the round part of the auger. Help?

Ok went outside and saw that the little bolt that connects the impeller to the auger was missing. It was missing when I bought the blower and I put a new bolt in, but its gone again. Anyways, new bolt, impeller still turns fine…chute gets clogged instantly, and when it does throw any snow its not far at all!

Impeller is cleaned, chute clogged!

This is a long shot. When I first used my blower I forgot about he RIO. I would back up and the blower would stop. I didnt know that it stopped. When I drove forward it would just fill up. The picture shows me a packed blower but the snow does not look too wet or heavy. Something is not working. Sorry I cant be more helpful I am going on 5 hours with my 47.

If this is a 2 stage blower the impeller rotates separately from the auger (impeller should spin MUCH faster)...can't understand how a bolt would connect them?
With the impeller shin pin sheared, can you spin by hand the auger????

The bolt I put in was under the john deere parts diagram online called "blower and gear drive" part #4 cap screw. At all times when I wiggled the auger the impeller moves with it. Thats good I assume! I can see the key is in there. I tightened both shears pins on the auger. This is sooo frustrating. My single stage 160 blower blows farther than my 2 stage 47…whats wrong with this! lol

You have a total of 3, sheer pins.. One on each side of the auger and one to the rear as you see in pic

Have you checked to see that the key on the shaft isn't missing? With the shear pin removed and the engine off, you should be able to spin the impeller by hand. The plate which is next to the impeller and and which the shear bolt goes through should be immovable though.
Picture of the impeller shear bolt and the spares that come with the blower. I will remove them from that spot. I would rather have them handy instead of having to unscrew them in the cold. They are are PIA to remove.

Was the blower used on a 400 series? I ask this because I don't know if all Deere tractors such as front mowers run the PTO in the same direction.

A friend of mine bought a used rear PTO blower and was having the same problem that you describe,it turned out the impeller was turning the right direction but was made for the opposite direction.

Yeah that bolt/shear pin the rear is the one I replaced when I got the machine since it was missing. It fell off today so I put that in again…so now I am sure all 3 shear pins are there! I wasn't able to spin the impeller freely though when the bolt wasn't in….isnt that because of the keyway / and the blower being hooked to the tractor?

I would leave those ones right where they and purchase some new ones to put in that handy spot that whey when you can't remember where that handy spot is you will still have the less handy ones:thThumbsU

You know I wondered that myself….the guy I got it from said he had a 445, but who knows. Well the auger rotates from the top down….is that the right way?

Not sure about that.Just be sure that it scoops the snow whatever direction it turns.It should turn in the direction the impeller is pointed and something is wrong if it does not.
