Side Gauge Wheel Adjustment
Refer to Figure 48
Disk-to-wheel angle and clearance ideally has the wheel
just touching the disk when the wheel is raised to plant-
ing depth (is up against the stop set by the “T” handle).
The goal is to have both disks and wheels turn freely, but
keep soil and trash from getting between them.
These two adjustments interact with each other. Chang-
ing one requires at least checking the other.
In addition to changing the disk angle due to changing
depth or new field conditions, these two settings may
need attention over time as the disk and wheels wear
from normal use. This adjustment also needs to be made
if any opener components are replaced.

Refer to Figure 49
For 2in (5cm) planting depth, adjust side gauge wheel
angle so wheels contact row unit disks at the bottom of
wheel. Check with row units in 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.
Note: Wheels should be out far enough so disks and
wheels turn freely.
Refer to Figure 51 on page 38
To adjust side gauge wheels:
1. Raise the drill.
2. Loosen hex-head bolt . Move wheel and arm out
on O-ring bushing.
3. Loosen pivot bolt Turn hex adjuster so indicator
notch is at 5 o’clock to 7 o’clock.
Note: Use this as the starting point for adjustment.
4. Move wheel arm in so side gauge wheel contacts
row unit disk. Tighten hex-head bolt
to clamp arm
around bushing and shank.
5. Check wheel-to-disk contact at 2in planting depth, as
shown in Figure 50. Lift wheel 2in, check contact and
release. When let go, wheel should fall freely.
• If wheel does not contact disk at bottom to area where
blade leaves contact with soil, move hex adjuster until
wheel is angled for proper contact with disk.
