Figure 5-7: Scraper Adjustment
1. Scrapers should be set initially as close to the disc
blade as possible without rubbing (approximately
1/8") (See Figures 5-7.) A slotted hole on each
scraper mount is provided for individual adjustment.
2. As blade wear occurs, scraper adjustment may be
necessary to maintain proper scraping function.
Disc Blades
1. The 6510 Disc is equipped with full concavity
notched disc blades on both front and rear. This is
4-15/16" for the 32" diameter blades and 5-1/8" for
the 36" diameter blades. The use of other concavity
blades can give unpredictable results and is not
recommended.
2. The 32" diameter blades with 10mm thickness are
used for normal working conditions. The 36" diameter
blades with 12mm thickness offer longer life cycle
and more aggressive tillage.
3. On new machines and after removing disc gangs
from frame, check and tighten all disc gang mounting
hardware daily for the first 2 weeks (See
Figure 5-10.)
4. On new machines and after changing disc blades,
check and tighten all disc gang shafts after the first 8,
30 & 120 hours of service (See Figure 5-8..)
OPERATION AND MAINTENANCE
Figure 5-8: Disc Gang Shaft
DANGER
Disc blades are extremely sharp. Exercise
extreme care when working on or near disc
blades. Do not allow discs to roll over or fall onto
any bodily part. Do not allow wrenches to slip
when working near disc blades. Never push
wrenches toward disc blades. Do not climb over
machine above disc blades. Failure to stay clear
of disc blade edges can cause serious personal
injury or death.
CAUTION
Tighten all 2-1/2" nuts to 4,500 foot-pounds of
torque (See Figure 5-9.)
