Any seed residue on disks may attract
pests. Fully enclose dry disks to prevent
rodent damage.

Side Depth Wheels
Sharp Object Hazard
Disk blades are sharp. To avoid serious injury,
wear gloves when working in this area.
The side depth wheels are preset at the factory. With
normal wear, it may become necessary to make
adjustments so the wheel remains close to the disk.
1. Lift the side depth wheel off the ground. Move the
tire in and out to check for end play. Check for
roughness in the bearing by rotating the wheel. If
the bearings are rough, inspect and replace, if
necessary.
2. Loosen the clamp bolt (1) and slide the depth
wheel arm (2) in to take up the gap between the
wheel and disk blade. If more adjustment is
needed:
a. Remove the bolt (3) and wheel (4).
b. Remove the shims (5) from the inside of the
wheel and place them on the outside of the
wheel (6).
Always place removed shims from the inside
to the outside. When installed, the wheel
should turn freely and not hit the arm at the
curve. Do not add any more shims than
necessary.
c. Remove the depth wheel arm (2) from the
row unit.
d. Remove the bushing (7) from the sleeve (8)
and check for wear. If necessary, replace the
bushing.
e. When reinstalling the depth wheels, align the
tab on the hex adjustment (9) with the notch
in the bushing. Install the bolt and tighten.
f. Adjust side depth wheels.

Disk Spreaders and Scrapers
Sharp Object Hazard
Disk blades are sharp. To avoid serious injury,
wear gloves when working in this area.
1. Remove the side depth wheels from the arms to
access row unit disks and scrapers.
2. With the unit raised, check the blade spreader (1)
for wear. Replace the spreader if it is 1/2 in.
(13mm) wide or narrower. To replace:
a. Remove the disk blade (2).
b. Drive out the roll pins (3).
c. Install the new spreader.
For proper operation, the scraper separator must
be a little loose in the holder and between the
blades.
3. When reinstalling disk blades, put two shim
washers (4) between the bearing and shank on
each blade. Tighten the bolts.
You may need fewer inside shim washers on
worn disks.
4. Check that outside disk scrapers (5) are formed
to the disk blades to help remove any mud. Bend
or twist the scrapers to fit the blades as necessary.
After every 200 acres (80 hectares) of operation,
check outside scrapers for proper adjustment
and wear. Replace the outside scrapers, as
necessary.
