OPERATION AND MAINTENANCE

Scraper Adjustment

The disc is equipped with rigid scrapers at regular spools

with dual scrapers at the disc bearings.

Figure 4-14: Scraper Adjustment

Figure 4-15: 1,250 Foot-Pounds of Torque

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.
