Side Gauge Wheels 20 Series Openers
Refer to Figure 21
The side gauge wheels have two, interrelated
adjustments:
•
angle of side gauge wheel, and
•
distance between side gauge wheel and row
unit disk.
 Wheel touches at bottom and gaps open 3/8” to 5/8”
at top.
Refer to Figure 22
Adjust side-gauge-wheel angle so the wheels contact
the row unit disks between 4 and 8 o’clock at the bottom
of wheel.
At the same time, keep the side gauge wheels close to
the opener disks so openers do not plug with soil or
trash but far enough out so the disks and wheels turn
freely.
If contact point is between 4 to 8 o’clock but distance to tire
is not correct,
then add or remove shims as needed. DO NOT
ADJUST BEARING AS THAT WILL ADJUST WHEEL-TO-
DISK CONTACT AREA ONLY.
Refer to Figure 23
To adjust Wheel-to-Disk contact area of side gauge
wheels:
1. Raise drill slightly to remove weight from side
gauge wheels.
2. Loosen hex-head bolt (1). Move wheel and arm out
on o-ring bushing.
3. Loosen pivot bolt (2). Turn hex adjuster (3) so roll
pin (4) is at 1 o’clock. 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 (1) to clamp
arm around bushing and shank.
5. Check the wheel-to-disk contact. Lift wheel and
arm. When let go, the wheel should fall freely.
•
If wheel does not contact disk from 4 to 8
o’clock
, move hex adjuster until wheel is
angled for proper contact with disk.
•
If wheel does not fall freely , loosen hex-head
bolt(1) and slide wheel arm out just until wheel
and arm move freely. Re-tighten hex-head bolt.
