Row Unit Lock-Up
The openers can be pinned in the up position to
accommodate 30” row spacing.
Refer to Figure 111 and Figure 112
Lock-up pins are not standard on all row spacings. Refer
to page 111 for additional or replacement lock-up pins.
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
.
Certain Machine Damage:
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 111 and Figure 112
4.
When pin
is not being used for opener lock up,
always return pin to the storage
position.

Loss of Control and Sharp Object Hazards:
Do not lift a row unit by hand. The weight of the unit, plus the
spring force (even at minimum) is too great (plus, a free hand
is needed for pinning). Even with multiple people lifting,
hand-lifting is unsafe - there are numerous sharp edges, and
the row unit will snap down violently if a grip is lost.
