Alignment
If one closing wheel is running in the seed trench
or closing wheels are not centered over the seed
trench, adjust closing wheels as follows.
Refer to Figure 35
1. Raise the drill slightly to remove weight from
closing wheels.
2. Loosen two 1/2-inch mounting bolts (1).
3. Turn adjuster cam (2) left or right to center
wheels over the seed trench.
Torque 1/2-inch mounting bolts as recommended,
see “Appendix,” page 159.
25 Series Lock-Up
The openers can be pinned in the up position to
accommodate 30” row spacing.
Refer to Figure 36
4. 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.
5. 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.
6. 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 37
When pin is not being used for opener lock-up al-
ways return pin to the storage position.
