1. Rigid scrapers should be set initially as close to the
disc blade as possible without rubbing
(approximately 1/8") (See Figure 4-14.) 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 rear
position to position scraper closer to the outer edge
of the disc blade. This position will perform better in
wet and heavier residue conditions. The blade may
be moved forward 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.
