Side Gauge Wheel Adjustment
Refer to Figure 88 and Figure 89
Disc-to-wheel angle and clearance ideally has the wheel
just touching the disc when the wheel is raised to
planting depth (is up against the stop set by the “T”
handle. The goal is to have both disc 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 disc angle due to changing
depth or new field conditions, these two settings may
need attention over time as the disc and wheels wear
from normal use. This adjustment will also need to be made if any opener components are replaced.
For 2 inch (5.1 cm) planting depth, adjust side gauge
wheel angle so wheels contact row unit discs 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 discs so openers do not plug with soil or trash.
Wheels should be out far enough so discs and wheels
turn freely.
To adjust side gauge wheels:
1. Raise the implement name 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.
Use this as the starting point for adjustment.
4. Move wheel arm in so side gauge wheel contacts
row unit disc. Tighten hex-head bolt
to clamp arm
around bushing and shank.
5. Check wheel-to-disc contact at 2 inch (5.2 cm)
planting depth. Lift wheel 2 inch, check contact and
release. When let go, wheel should fall freely.
•
If wheel does not contact disc at bottom to area
where blade leaves contact with soil
, move hex
adjuster until wheel is angled for proper contact with
disc.
