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

Hi all - please help an ignorant fool with his first snowblower.....  I've inherited a Yamaha 2 stage machine.  It's about 15 years old and in fantastic condition.  The engine runs great, and until the first time I used it, so did the auger.  After probably going into a pile of snow too fast, the auger has stopped working.  Nothing happens when hold the auger handle down.  People have said that I've more than likely busted a shear pin, but I can't seem to find a broken one.  Currently, when the machine is off, i can manually turn the auger, which in turn, rotates the impellar.  If I have broken a schear pin, would this be happening?

Thank you!
