When performing seasonal checks, lower the planter
to put the chain at minimum idler spring tension.
Lift the spring off the idler assembly. Check that the
idler pivots freely. Re - attach the spring.

Side Depth Wheels
Sharp Object Hazard
Disks are sharp. To avoid serious injury, wear
gloves when working in this area.
1. Lift the side depth wheel off the ground.
Move the tire in and out to inspect for end play.
Inspect for roughness in the bearing by rotating
the wheel. If the bearings are rough, inspect and
replace if necessary.
2. 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.
Loosen the clamp bolt (1) and slide the depth
wheel arm (2) in to take up the gap between the
wheel and disk.
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. Disassemble 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 the depth wheels. See “
Move the
T-handle back (B) or deeper planting. ” on
page 48.

Disk Separators and Scrapers
Sharp Object Hazard
Disks 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 disk separator (1)
for wear. Replace separator if it is 1/2 inch (13
mm) wide or narrower. To replace:
a. Remove the disk (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 disks, put two shim washers
(4) between the bearing and shank on each disk.
Tighten the bolts.
You may need fewer inside shim washers on
worn disks. Check disk contact. See
page 48.
4. Check that outside disk scrapers (5) are formed
to the disks to help remove any mud. Bend or
twist the scrapers to fit the disks as necessary.
After every 200 acres (80 hectares) of operation,
check outside scrapers for proper adjustment
