Row Unit Disks
1.
Remove side gauge wheels from arms to ac-
cess row unit disks.
1. Check the disk blades for wear. To maintain
proper planting depth, replace if worn to a di-
ameter of 14 1/2 inches or less.
Refer to Figure 71
2. Check contact point between disk blades.
Place a piece of paper in top gap between
disks blades. Bring paper down until it stops.
In lower gap place another piece of paper.
Bring paper up until it stops. Measure the dis-
tance between two pieces of paper. The dis-
tance must be between 1/2 and 1 3/4 inches.
Add or remove shims as needed to get the
correct contact point.
Row Unit Side Wheels
Refer to Figure 72
1. 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 the
bearings are rough, inspect and replace if
necessary.
1. Check for the correct number of shims (1) be-
tween the side gauge wheel (2) and the wheel
arm (3). There must be at least one shim be-
tween the wheel bearing and arm. When in-
stalled, the wheel should turn freely and not
hit the arm at the curve. Do not add any more
shims than necessary.
2. Disassemble side-gauge-wheel arm from row
unit. Remove bushing (4) from sleeve (5) and
check bushing for wear. Replace bushing if
necessary.
3. When reinstalling side gauge wheels, align
tab on hex adjustment (6) with notch in bush-
ing. Replace bolt and tighten.
4. To prevent plugging loosen clamp bolt (7) and
slide arm inward to take up gap between side
wheel and disk blade.
5. Adjust side gauge wheels. Refer to “Adjust-
ments,” page 28.
