Adjusting Disk Angle & Side Depth Wheels
Refer to Figure 77
For 2 inch planting depth, adjust side depth wheel angle
so wheels contact row unit disks 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 disks so openers do not plug with soil or trash.
Note: Wheels should be out far enough so disks and
wheels turn freely.
Refer to Figure 78
To adjust side gauge wheels:
1. Raise planter slightly removing weight from side
gauge wheels.
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.
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
to clamp arm
around bushing and shank.
5. Check wheel-to-disk contact at 2 inch planting depth.
Lift wheel 2 inch 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
and slide wheel arm out just until wheel and arm move
freely. Retighten hex-head bolt
according to grade:
1 ⁄
2
inch Grade 5 bolt on 25 series, 75 foot-pounds.
1 ⁄
2
inch Grade 8 bolt on 25 series, 110 foot-pounds.
Note: Use “Torque Values Chart” on page 126 for
reference.
6. Keep turning hex adjuster and moving wheel arm
until the wheel is adjusted properly. When satisfied,
tighten pivot bolt
to 110 foot-pounds.
