Figure 4-24: Opener Scraper Adjustment
Opener Scraper Adjustment
1. The opener is equipped with a scraper to keep the
inside surfaces of the opener blades clean. In dryer
conditions, the scraper can be adjusted farther away
from the opener blades for greater clearance. In
wetter conditions, it will be necessary to adjust the
scraper blade closer to the opener blade.

CAUTION
2. To adjust the scraper blade, loosen the 1/2-13 hex
flange spiralock nut holding the blade, and slide the
blade up or down to achieve the desired clearance
(See Figure 4-24.) Retighten the 1/2-13 hex flange
spiralock nut. Carefully rotate the opener blades to
make sure the blades will turn freely and not drag on
the scraper.
3. A properly maintained opener blade pinch point will
reduce the amount of soil that enters between the
opener blades. This will in turn allow the scraper to
operate in a cleaner environment and reduce scraper
wear.
