OPERATION AND MAINTENANCE
4-37
Opener – Press Wheel
Adjustment
1.
The seeding depth of each individual opener is
controlled by the press wheel depth adjustment
To change the depth of each press
wheel, raise the openers so there is not any weight
on the press wheel. Pull up on the adjusting handle
and slide the depth stop forward or rearward to
obtain the desired seeding depth. Each notch
represents approximately 5/16” in depth. Slide the
handle forward for shallower seed placement, and
rearward for deeper seed placement.
IMPORTANT
Increasing opener down pressure does not increase
seed placement depth.
2.
As long as the press wheel is carrying weight, the
seeding depth is regulated by the press wheel
adjustment. An increase in down pressure does not
change the depth of seed placement.
3.
Make sure the hitch is level when planting to insure
consistent planting depth. A hitch that is too high or
too low can change how the press wheel contacts the
ground and affect seeding depth.
4.
When planting seeds shallow, or in loose/soft
conditions, it may be necessary to install stroke
control stops on the hydraulic cylinders on pull hitch.
This will allow the drill transport tires to carry more
weight, raising the drill, and keeping the openers
from planting too deep. Adjusting the gauge wheel
height on 3-point drills for shallower seed placement.

Opener Scraper Adjustment
1.
The opener is equipped with a scraper to keep the
inside surfaces of the opener blades clean. In dryer
conditions, the scraper can be adjusted farther away
from the opener blades for greater clearance. In
wetter conditions, it will be necessary to adjust the
scraper blade closer to the opener blade.
CAUTION
2.
To adjust the scraper blade, loosen the 1/2-13 hex
flange lock nut holding the blade, and slide the blade
up or down to achieve the desired clearance
Re tighten the 1/2-13 hex flange lock
nut. Carefully rotate the opener blades to make sure
the blades will turn freely and not drag on the
scraper.
3.
A properly maintained opener blade pinch point will
reduce the amount of soil that enters between the
opener blades. This will in turn allow the scraper to
operate in a cleaner environment and reduce scraper
wear.
