4-12 SCRAPER ADJUSTMENT
The VT Plus is equipped with rigid scrapers at
regular spools with dual scrapers at the disc bear-
ings.
4-12.1 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 an-
gle-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.
4-12.2 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 condi-
tions and climates where less scraper action
is needed.
4-12.3 Dual scrapers are provided at the bear-
ing locations to scrape the disc blade and to
limit the amount of soil and residue carried
into the bearing hanger. Scrapers can be in-
dividually adjusted in or out from the concave
side of the disc blade.
