PL5700 Planter Table of Contents Index Operation
The goal is to have both disks and wheels turn freely,
but keep soil and trash from getting between them.
The side depth wheels have two adjustments.
Changing one requires at least checking the other.
The two adjustments are:

angle of side depth wheel

distance between side depth wheels and disks.
In addition to changing the disk angle due to
changing depth or new field conditions, the two
settings may need attention over time as the disk
and wheels wear from normal use. This adjustment
will also need to be made if any opener components
are replaced.
For 2 inch (5 cm) planting depth, adjust the side
depth wheel angle so the wheels contact the row unit
disks at the bottom of the wheel and the gap is
3/8 to 5/8 inch (9.5 to 16 mm) at the top. Check with
row units in the soil so wheels are held up.
At the same time, keep side depth wheels close to
opener disks so openers do not plug with soil or
trash. Wheels should be out far enough so disks and
wheels turn freely.
To adjust the side depth wheels:
1. Raise the planter slightly, removing the weight
from the side depth wheels.
2. Loosen the bolt (1).
3. Move the wheel and arm out on the O-ring
bushing.
4. Loosen the pivot bolt (2).
5. Turn the hex adjuster (3) so the indicator notch
(4) is at 5 o’clock to 7 o’clock. Use this as the
starting point for adjustment.
6. Move the wheel arm in so the side depth wheel
contacts the row unit disk.
7. Tighten the bolt (1) to clamp the arm around the
bushing and shank.
8. Check wheel-to-disk contact at 2 inch (5 cm)
planting depth. Lift wheel 2 inch (5 cm), check
the contact, and release. When let go, the wheel
should fall freely.
 If the wheel does not contact the disk at the
bottom to the area where the disk leaves
contact with the soil, move the hex adjuster
until the wheel is angled for proper contact
with the disk.

If the wheel does not fall freely, loosen the
bolt (1) and slide the wheel arm out just until
the wheel and arm move freely. Tighten the
bolt as follows:
Grade 5 bolt - 76 ft lb (105 Nm)
Grade 8 bolt - 110 ft lb (150 Nm)
9. Keep turning the hex adjuster and moving the
wheel arm until the wheel is adjusted properly.
10. When properly adjusted, tighten the pivot bolt (2)
to 110 ft lb (150 Nm).
