Lock-Up
The openers can be pinned in the up position to
accommodate 30” row spacing.
Refer to Figure 43
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 low-
ered position. If the pin is inserted below the par-
allel arm it WILL damage opener soon after
planting begins.
Refer to Figure 44
When pin is not being used for opener lock-up al-
ways return pin to the storage position.
