Small Engines (Lawn Mowers, etc.)/5HP Single Stage Snowblower not throwing snow properly


I have a 5hp Single stage Yard machines snowblower that is not throwing snow properly. I have checked the rpm's and they are at 4420 What is normal?. I checked the belt and it seems to be fine, I adjusted it and does not spin when the handle is down. It does not have shear pins. I heard about a key on flywheel, this is my friends snowblower and he it hit something hard and stopped stalled.  It is easy to start but does not throw well. How do I check the paddle if it is too worn down? Thanks

ANSWER: Often times the paddles will have wear mark indicators, a hole in the outer edge of the paddles.

I've been told a good rule of thumb is if you can put your fingers between the paddles and the snowblower bucket, when the paddles are closest to the rear of the bucket, that the paddles need to be replaced.

If it starts easy, runs good and has enough power then I doubt the flywheel key is sheared.  

How old is the blower?  How many hours are on the paddles?

Thanks for getting back so quick. I just tried the snowblower in about 2 inches of fresh snow and it clogs up and the main pulley attached to engine stops, then if I knock the snow out from the auger it throws snow again the belt is not slipping. Do you think it might be the key. It bogs down under load........Thanks Mike

The RPM is a little fast.

There are a lot of possibilities that could cause your problem.

Where do you live?  Do you know if the paddles have ever been replaced?  What is the model number?  The model number will be located on a sticker, about the size of a business card and the format will be something like 123-456-789 or similar.

Did the snowblower work well in the past?

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
