PL5500 Planter
Operation
4. Remove bolt, lock washer, and nut (4).
5. Move the coulter blade to the new position.
6. Install the bolt and fasten the lock washer and
nut.
If a worn coulter cannot be adjusted to the proper
operation depth, replace the coulter blade.
Coulter Row Alignment
For unit
-
mount coulters, the ideal alignment is for the
blade to open a furrow directly ahead of the opener
disks.
To check alignment, sight along the coulter blade
centerline (1), the gap between the opener blades,
and the centerline between the press wheels. If they
are out of alignment, either the coulter or the press
wheels (or both) may need to be adjusted.
Operate the planter on test ground (no seed
required), and verify that the opener blades are in the
groove opened by the coulter, and that the press
wheels are centered over the furrow. See “
To adjust coulter alignment, loosen the four bolts that
attach the coulter bracket to the row unit. The holes
on the row unit are slotted (2) for adjustment.
Keep the coulter blade vertical while adjusting.
If the blade cannot be aligned, check that the blade
spindle is using the same hole location on each side
of the bracket.
Seed Firmer
Sharp Object Hazard
Disk blades are sharp. To avoid serious injury,
wear gloves when working in this area.
Keeton
®
Seed Firmer
A Keeton
®
seed firmer has a polymer shape that
slides down the seed trench. It traps the seeds as
they exit the seed tube and firms them into the
bottom of the seed trench.
The Keeton Seed Firmer is provided with a preset
tension which is recommended for the first year of
planting. The tension screw (1) can be tightened after
the first year, according to your needs. The seed
firmers should provide just enough tension to push
seeds to the bottom of the trench.
Measure the distance from the ground to the head of
the tension screw. This distance should be 4 to 4 1/2
inch (10.2 to 11.4 cm).
If adjustment is necessary, loosen the bolts in the
mounting bracket and select different holes until the
proper measurement is reached.
Liquid Fertilizer
Agricultural Chemical Hazard
Some chemicals will cause serious burns, lung
damage, and death. Avoid contact with skin or
eyes. Avoid prolonged breathing of chemical
fumes. Wear respirator and other protective
equipment as required by chemical manufacturer.
Seek medical assistance immediately if accident
occurs. Know what to do in case of an accident.
Plugging Risk
Load chemicals just before using. If fertilizer
remains in the tanks for extended periods,
settling of material and system plugging will
occur.
