Lock-Up
The openers can be pinned in the up position to
accommodate 30” row spacing.
Refer to Figure 29
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
lower 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 30
When pin is not being used for opener lock-up al-
ways return pin to the storage position.
