1. Rigid scrapers should be set initially as close to the
disc blade as possible without rubbing
(approximately 1/8")
at the top of each scraper is provided for individual
adjustment. Loosen 1/2 flange lock nut for reversible
scraper or 1/2 lock nuts for dual scrapers to slide
scrapers to get the 1/8" spacing from disc blade.
Scraper arms are made of spring steel. In wet
conditions, the scraper may be set against the disc
blade and can function as a spring-loaded scraper.
2. Scraper blades have two positions and are
reversible. The blades are initially set in the forward
position to position scraper closer to the disc spool.
This position will perform better in wet and heavier
residue conditions. The blade may be moved
rearward for more scraper action at the outer edge of
the disc if desired.
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.

Spring Shanks

The Tilloll is equipped with spring shanks on a 9" shank
spacing.
1. There is no regular maintenance required on the
shanks. The main pivot point of the spring shank has
replaceable hardened wear bushings that pivot on a
heat treated clamp bushing.

2. When adjusting or assembling the spring assembly,
tighten the upper spring bolt, but leave
approximately1/4" gap above the spring jam nut
Figure 4-11. This will leave the proper clearance for
the spring to pivot. Lock the jam nut against the top of
the spring, not the top of the mount.

Sweeps

The spring shanks will accept a wide variety of sweeps
and points. Recommended sweeps for the Tilloll are
standard 47º sweeps in 10 inch widths using 7/16
diameter mounting hardware.
Check clearances when using larger sweeps to avoid
interference with tires.
