Scraper Adjustment

The Disc is equipped with rigid scrapers at regular spools
with dual scrapers at the disc bearings.

1. Rigid scrapers should be set initially as close to the
disc blade as possible without rubbing
(approximately 1/8") (See Figure 4-15.) A slotted
hole at the top of each scraper is provided for
individual adjustment. Adjustments may be made for
entire gangs, by loosening the u-bolts around the
angle-iron scraper bars and sliding the whole bar.
Scraper arms are made of spring steel. In wet
conditions, the scraper may be set against the disc
blade and will function as a spring-loaded scraper.
2. Scraper blades have two positions and are
reversible. The blades are initially set in the front
position to position scraper closer to the spool. This
position will perform better in wet and heavier residue
conditions. The blade may be moved back for dryer
conditions and climates where less scraper action is
needed.
3. Dual scrapers are provided at the bearing locations
to scrape the disc blade and to limit the amount of
soil and residue carried into the bearing hanger.
Scrapers can be individually adjusted in or out from
the concave side of the disc blade.
