Loosen shift lever nuts (B, Figure 6), and position the
shift speed lever (A) in the lowest forward speed.
On smooth surfaces such as concrete or asphalt, the
scraper bar should scrape the surface. On surfaces such
as gravel, the scraper bar should be high enough so that
it will not pick up gravel or debris.

The height of the scraper bar is controlled by raising or
lowering the Skid Shoes (See Figure 8).
