4-4.9 Disc Gang Operation. The disc gangs
may be set at an angle of 10, 15, or 20 De-
grees. The angle is adjusted by removing the
disc angle adjust pins and moving the outer
end of the disc gangs to the angle desired.
Reinstall pins to hold the disc at a desired
angle. (See Figure 3-3.)
IMPORTANT
DISC GANGS ARE ASSEMBLED TO PROVIDE
CLEARANCE BETWEEN FRONT GANGS AT
10
o
. IF THERE IS TOO MUCH GAP BETWEEN
GANGS AT 15
o
AND 20
o
, THE FRONT GANGS
CAN BE SLID IN ON THE TUBES 1”.
4-4.10 Disc Gang Adjustment
a. Raise the disc gangs to the full up position,
cylinders retracted.
b. Adjust rear disc gang radius rods for a 1/8"
clearance between the disc gang frame 4x6
tube and the angle adjust brackets on the
main frame. Rear disc gangs should always
be at this adjustment.
c. Front disc gangs may be adjusted to the
same depth as the rear gangs or adjusted to
run deeper than the rear gangs by adjusting
the front disc gang radius rods.
4-4.11 Check disc scrapers for proper pressure
and contact against disc blades (See Sec-
tion 4-2 to adjust).
4-4.12 The spring shanks can be adjusted to
different depths and penetrating angles. Use
the following procedure to adjust depths and
angles:
a. Remove the front spring anchor bolt from
the top of the front bracket.
b. Place the bolt into the other hole.
IMPORTANT
THE SHANK DEPTH CHANGES APPROXI-
MATELY 1".
4-5 WHEEL BEARING MAINTENANCE
Wheel bearing maintenance should be per-
formed at the beginning of every season of use.
Check the wheel bearings periodically for exces-
sive end play. If needed, adjust or replace them
using the following procedure :
4-5.1 Place the frame on blocks or stands suf-
ficient to lift the tire clear of the ground. Re-
move the wheel.
4-5.2 Remove the hub cap, cotter pin, slotted
nut and washer.
4-5.3 Remove the hub. Clean and inspect the
bearings and hub cavity. Replace any worn
or defective parts.
4-5.4 Repack the bearings using a high-
quality wheel bearing grease.
4-5.5 Replace the hub with a new seal and
the inner bearing in place.
4-5.6 Install the outer bearing cone, washer
and slotted nut.
4-5.7 Tighten the slotted nut while rotating the
hub until there is a slight resistance to wheel
rotation. Then, back the slotted nut off one
notch, until the wheel rotates freely without
end play.
4-5.8 Install a new cotter pin and replace the
hub cap.
4-6 LUBRICATION
Several parts of the Model DR8700 Disc Rip-
per need periodic lubrication. Use of a high grade
multi-purpose grease is recommended. Refer to
the Lubrication Chart (See Figure 4-2) to locate lu-
brication points and for a recommended mainte-
nance schedule.
