Scraper Blade
The scraper blade allows the back of the housing to
keep better contact with the surface being cleared. It
also prevents damage to the housing from normal
wear.
IMPORTANT: DO NOT allow Scraper Blade to wear
too far or Auger/Impeller housing will become
damaged.
Runners
The runners control the distance between the scraper
blade and the ground. Adjust runners equally to keep
blade level with the ground. Refer to Pre-Start on
page 12 for recommended settings.
