Spreaders and Scrapers
Note: Applies to all row unit Series.
Remove side gauge wheels from arms to access
row-unit disks and scrapers.
With the unit raised, check blade spreader
wear. Replace spreader if it is
inch (13 mm) wide
or narrower. To replace, remove disk blades
out roll pins
, and install new spreader.
When reinstalling disk blades, put two shims
between bearing and shank on each blade. Tighten
Check amount of contact between blades, and adjust
number of shims as needed. Store extra shims on
outside of blade. See “Opener Disc Contact
Region” on page 52.
Check that outside disk scrapers
are formed to
disk blades to help remove any mud. Bend/twist
scrapers to fit blades as needed. Every 200 acres of
operation, check outside scrapers for adjustment
and wear. Replace outside scrapers as necessary.
Row-Unit Side Wheels
Refer to Figure 93
Lift opener side wheel off the ground.
Move tire in and
out to check for end play. Check for roughness in
bearing by rotating wheel. If bearings are rough,
inspect and replace if necessary.
Side wheels are preset at the factory. Due to normal
wear it may become necessary to make adjustments
so the wheel remains close to the disk. To prevent
plugging, loosen clamp bolt
and slide arm inward
to take up gap between side wheel and disk blade. If
more adjustment is needed, go to step 3.
. Remove shims
from the inside of wheel
and place them on the
outside of wheel. Always place removed shims from
the inside to the outside. When installed, wheel
should turn freely and not hit the arm at the curve.
Do not add any more shims than necessary.
Disassemble side gauge wheel arm
and check for
wear. If necessary, replace bushing.
When reinstalling side gauge wheels, align tab on
with notch in bushing. Replace
bolt and tighten.
Adjust side gauge wheels. Refer to see “Side Gauge
Wheel Adjustment” on page 53.
Note: You may need fewer washers under worn disks.
