4. Carefully remove the disk. Do not lose the hub
components and spacer washers (3 and 4).
5. To reduce the spacing between disks, move one
spacer washer from the inside (3) to the outside
(4) of the disk.
6. Reassemble and check the disk contact.
Side Gauge Wheel Angle and Clearance
For disk-to-wheel angle and clearance the side
gauge wheel (1) should just be touching the opener
disk (2) when the wheel is raised to planting depth.
The goal is to have both disks and wheels turn freely,
but keep soil and trash from getting between them.
The side gauge wheel have two related adjustments.
Changing one requires at least checking the other.
The two adjustments are:

angle of side gauge wheel, and

distance between side gauge wheels and disks.
In addition to changing the disk angle due to
changing depth or new field conditions, the two
interrelated adjustments may need attention over
time as the disk and wheels wear from normal use.
This adjustment will also need to be made when any
opener components are replaced.
For 2 inch (5 cm) planting depth, adjust the side
gauge wheel angle so the wheels contact the row
unit disks at the bottom of the wheel and the gap is 3/
8 to 5/8 inch (9.5 mm to 16 mm) at the top. Check
with row units in the soil so wheels are held up.
At the same time, keep side gauge wheels close to
opener disks so openers do not plug with soil or
trash.
To adjust the side gauge wheels:
1. Raise the planter slightly, removing the weight
from the side gauge wheels.
2. Loosen the bolt (1).
3. Move the wheel and arm out on O-ring bushing.
4. Loosen the pivot bolt (2).
5. Turn hex adjuster (3) so the indicator notch (4) is
at 5 o’clock to 7 o’clock. Use this as the starting
point for adjustment.
6. Move wheel arm in so the side gauge wheel
contacts the row unit disk.
7. Tighten the bolt (1) to clamp the arm around the
bushing and shank.
8. Check wheel-to disk contact at 2 inch (5 cm)
planting depth. Lift wheel 2 inch (5 cm), check the
contact, and release. When let go, the wheel
should fall freely.
 If the wheel does not contact the disk at the bottom to
the area where the blade leaves contact with the solid,
move the hex adjuster until the wheel is angled for
proper contact with the disk.
 If the wheel does not fall freely, loosen the bolt (1) and
slide the wheel arm out just until the wheel and arm
move freely.
 Tighten the bolts follows:
Grade 5 bolt - 76 ft-lb (105 Nm)
Grade 8 bolt - 110 ft-lb (150 Nm)
9. Keep turning the hex adjuster and moving the
wheel arm until the wheel is adjusted properly.
10. When properly adjusted, tighten the pivot bolt (2)
to 110 ft-lb (150 Nm).

Side Gauge Wheel Scraper (Option)
Side gauge wheel scrapers may be useful in moist or
sticky soils that tend to accumulate on gauge wheels
reducing the intended planting depth.
