When to Replace the Paddles on a Single Stage Snow blower
This is one of the most ask questions we get from snow blower owners. There are a few ways to check if your impeller paddles are needing replacement
1) If your snow blower isn't throwing the snow as far as it used to or you are getting snow plugging up in snow thrower then that the paddle impellers are worn and should be replaced.
2) Check the shape of the impeller tips if they are angled and shredding ( See Picture below) this is a sign the paddles are hitting the pavement and need replacing along with Scrapper bar is worn and needs to be replaced.
