I've found some good luck with a good quality brand of silicone. Best bet is
to spray it on while the machine is warm and dry, and do it the night before
you need the snow thrower.
If memory serves, my dad tried a lot of things on his snow shovel to keep
the snow from sticking. I think he said he liked Pam (R) cooking spray best.
Snow goes through a "chute". Minor spelling czech air-roar.
