OPERATION AND MAINTENANCE
Scraper Adjustment
The Finisholl is equipped with rigid scrapers at regular
disc spools at the disc bearings.
Figure 4-13: Scraper Adjustment
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. 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 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.
Shanks
The Finisholl is equipped with shanks on a four row
pattern with an 8" shank spacing. Shank assemblies may
be either s-tine or spring shanks.
S-tine Shanks
S-tine shanks may be used when there are no field
obstructions such as rocks and stumps, and with flatter
ground conditions. If fields contain rolling contours,
terraces, or obstructions, spring shanks are
recommended. There are no serviceable parts or
adjustments for the s-tine shank assembly.

Spring Shanks
1. The Finisholl may be equipped with spring shanks.
The spring shanks feature a 185 lb. point load and a
10" trip height to clear field obstructions. Shanks are
5/8 x 1-3/4 heat treated steel.
2. 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.
NOTE
Main pivot bolt should be tightened securely to
prevent rotation. Torque main pivot bolt to 140
ft.-lbs.
3. When adjusting or assembling the spring assembly,
tighten the upper spring bolt, but leave
approximately1/8" gap above the spring jam nut
See Figure 4-14. 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. Likewise,
do not over tighten the lower spring cross bolt.
Remove any slack in the bolt, but still allow the lower
spring to pivot freely.
Figure 4-14: Spring Adjustment
Sweeps
The spring or s-tine shanks will accept a wide variety of
sweeps and points. Recommended sweeps for the
cultivator are standard 47º sweeps in 7 to 11 inch widths
using 7/16 diameter mounting hardware.
Check clearances when using larger sweeps to avoid
interference with tires.
