Side Gauge Wheel Adjustments
Refer to Figure 48
The side gauge wheels have two, interrelated adjust-
ments:
• angle of side gauge wheel, and
• distance between side gauge wheels and disks.
Refer to Figure 49
Adjust side-gauge-wheel angle so wheels contact row-
unit disks at the bottom of wheel at 2in planting depth
and gaps open
3 ⁄
8
to 5 ⁄
8
in at top. 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.
However, wheels should be out far enough so disks and
wheels turn freely.
Refer to Figure 50
To adjust side gauge wheels:
1. Raise planter slightly removing weight from side
gauge wheels.
2. Loosen hex-head bolt
➀
. Move wheel and arm out
on o-ring bushing.
3. Loosen pivot bolt
➁
. Turn hex adjuster
➂
so indica-
tor notch
➃
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
➀
to clamp arm
around bushing and shank.
5. Check wheel-to-disk contact at 2in planting depth.
Lift wheel 2in 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.
• If wheel does not fall freely, loosen hex-head bolt
➀
and slide wheel arm out just until wheel and arm move
freely. Retighten hex-head bolt
➀
per grade:
1 ⁄
2
in Grade 5 bolt, 75 ft-lbs.
1 ⁄
2
in Grade 8 bolt, 110 ft-lbs.
6. Keep turning hex adjuster and moving wheel arm
until the wheel is adjusted properly. When satisfied,
tighten pivot bolt
➁
to 110 ft-lbs.
Note: Use “Torque Values Chart” on page 75 for refer-
ence.
