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.
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 in planting depth.
Lift wheel 2 in 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.

, loosen hex-head bolt
and slide wheel arm out just until wheel and arm move
freely. Tighten hex-head bolt
