A couple of posts above mentioned spraying various slippery substances into the discharge chute so that slush will not clog it. I found that to be absolutely necessary with my snowblower, or it clogs in slush very quickly. I use a DuPont dry spray with teflon , since I had a couple of cans on hand, but I'm sure most of the other suggestions ( vegetable oil, WD-40) also work . The first time I used my walk behind 24 inch wide snowblower , I was disappointed at the performance in wet snow. Then I read, on this forum, the slippery spray trick . Now, my snow blower almost never clogs ! What I can't understand is why the factory manual doesn't mention using a spray. They simply suggest going more slowly. That did not work for me.
The teflon spray comes out of the can as a liquid stream, and builds up a visible thickness on the chute after the volatiles evaporate. It stays effective for about 3 hours of use . I haven't tried using the spray on the auger or impeller wheel , since they usually don't clog. Is there any advantage to spraying those other parts ?
