Adjusting the Skids and Scraper - Fixed
Scraper models
1. Check the tire pressure. It must be between 17 and
20 psi (116-137 kPa) and the same on both sides so
the machine sets level.
2. Loosen the nuts that secure both skids so the skids
can slide up and down easily.
3. Support the side plates so they are at least ½”
(13mm) above a level surface (Fig. 070).
Fig 070 m-6938
4. Adjust the scraper to a minimum of 1/8” (3.2mm)
above and parallel to a level surface. Secure with
carriage bolts and locknuts.
5. Move the skids down until they are even with the
ground.
6. Firmly tighten the nuts securing both skids to the
auger sides.
7. Check to ensure that the rotating part of the auger
does not touch the ground. This can damage the
pavement as well as the auger.
Important: If the machine is to be used on rough,
broken or uneven pavement, adjust the skids to raise
the scraper. For gravel surfaces, adjust the skids further
down to prevent the snowthrower from picking up rocks.
The scraper pivots on the auger shaft bearings on each
side of the auger. It is necessary to remove the auger
assembly to replace the scraper. See auger gearbox
removal.

A pivoting scraper is more complex but has advantages
when used on paved surfaces. It can be set to scrape
down to the surface. Should it hit something solid, it
will slide rearward; two springs return it to the operating
position once it clears the object. However, use on a
gravel driveway may jam or damage the scraper, as
rocks can be forced between the scraper and housing.
Therefore, the pivoting scraper should not be used on
gravel surfaces (Fig. 071).
