Side Gauge Wheels
Refer to Figure 10
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 11
Adjust side-gauge-wheel angle so the wheels contact the
row unit disks at the bottom of wheel at 2” planting depth.
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 dis-
tance 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 12
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 start-
ing 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 at 2” planting depth. Lift
wheel and arm. When let go, the wheel should fall freely.
• If wheel does not contact disk at bottom to area
where blade leaves contact with soil, move hex ad-
juster 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.
• 1/2” Gr 8 bolt on 25 series, 110 ft-lbs.
NOTE: Use “Torque Values Chart”, on page 141 for ref-
erence.
