Double V Press Wheel Adjustment
Refer to Figure 58
The double V closing wheels (4) can be moved in-
ward and outward to alter how they close the seed
trench and press soil over the seed.
To move the wheels (4) in toward the center of the
trench, remove one of the 1/4 bushings (2) next to
the press wheel arm and position it under the
head of the bolt (1). On wider row spacings the
closing wheels (4) can be moved outward by plac-
ing two 1/4 spacers (2) inside next to the press
wheel arm (3).
Lock-Up
The openers can be pinned in the up position to
accommodate 30” row spacing.
Refer to Figure 59
1. Select the individual opener you want to keep
in the raised position. It is suggested that the
down pressure springs be set to the minimum
setting first.
2. Raise the opener high enough that the hole
for the pin is above the lower parallel arm.
This can easily be done by placing a small
block below the disc blades and setting the
drill down upon it.
3. Insert locking pin through both holes and low-
er the opener allowing the pin to rest on the
top of the lower parallel arm.
NOTE: Do not pin the opener while it is in the
lowered position. If the pin is inserted below
the parallel arm it WILL damage opener soon
after planting begins.
Refer to Figure 60
When pin is not being used for opener lock-up al-
ways return pin to the storage position.
