Side Gauge Wheel Adjustment
Refer to Figure 96
Disc-to-wheel angle and clearance ideally has the wheel
just touching the disk when the wheel is raised to
planting 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.
Changing 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 will also need to be
made if any opener components are replaced.
Refer to Figure 97
For 2 inches (5.1 cm) 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 99
To adjust side gauge wheels:
1.
Raise the planter and install lift cylinder locks.
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 2 inches (5.2 cm)
planting depth, as shown in Figure 98. Lift wheel
2 inches, 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.
