I have a Sears two stage snow blower. It's maybe ten years old and has a new engine. It works fine with one exception. The belt to the augur will slip off the flywheel for no apparent reason. I was ploughing today. I got
80% of the job done (about 40 minutes work) when suddenly, no augur. You open it up and the belt has jumped off the drive wheel. This has happened several times before. So far as I can see, the tension on the pulleys and the little guides are set properly. Running it with the cowling off, everything seems to work just fine. In fact when I got the belt back in place...no easy task with bare fingers in 5 degree weather...it ran just fine for the balance of the job. But I know it will happen again. Any ideas? ds- posted
