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 for recommended settings.
