Side Gauge Wheels for 20 and 25 Series
Openers
Refer to Figure 18
The side gauge wheels have two, interrelated adjustments:
• angle of side gauge wheel, and
• distance between side gauge wheel and row unit disk.
Refer to Figure 19
Adjust side-gauge-wheel angle so wheels contact row unit disks
at bottom of wheel at 2” planting depth.
At the same time, keep side gauge wheels close to opener disks
so openers do not plug with soil or trash but far enough out so
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 THAT WILL ADJUST
WHEEL-TO-DISK CONTACT AREA ONLY.
Refer to Figure 20
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 indicator
notch (4) 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
disk. Tighten hex-head bolt (1) to clamp arm around bush-
ing and shank.
5. Check wheel-to-disk contact at 2” planting depth. Lift wheel
and arm. 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.
• If wheel does not fall freely, loosen hex-head bolt (1) and
slide wheel arm out just until wheel and arm move freely.
Retighten hex-head bolt (1) according to grade:
• 1/2” Gr 5 bolt on 25 series, 75 ft-lbs.
• 7/16” Gr 8 bolt on 20 series, 70 ft-lbs.
• 1/2” Gr 8 bolt on 25 series, 110 ft-lbs.
• 5/8” Gr 8 bolt on 20 series, 150 ft-lbs.
NOTE: Use “Torque Values Chart”, on page 159 for reference.

until the wheel is adjusted properly. When satis-
fied, tighten pivot bolt (2) to 110 foot-pounds.
