Row Unit Lock-Up
Wear of ground-contact components of unused rows can
be minimized by locking up a row unit. Lock-up requires
use of one optional pin (part number is 805-033C) for
each row locked up.
Refer to Figure 58 (depicting similar 10HDP row)
When not in use, lock-up pins are normally stored in a
hole
at the top of the opener mount.
1. Raise the drill. Although this adjustment can be
made with the drill lowered, the row unit springs
would be in tension, and require more effort. The
extra force may also damage tools.
2. Set the down pressure springs to minimum force, per
the instructions on page 48.
Refer to Figure 59 (depicting similar 10HDP row)
3.
Raise the row unit high enough that the hole for
the pin is above the lower parallel arm :
a. use a hoist at the rear of the opener,
b. use a jack under the opener extension, or;
c. place a block under the row, and lower drill.
Equipment Damage Risk:
Do not pin the row unit while it is in the lowered position. If
the pin is inserted below the parallel arm, row unit damage
will occur when planting begins.
4. Remove the pin from the storage hole and insert and
secure it in the lock-up hole.
5. Lower row unit. Parallel arm rests on lock-up pin.
6. Repeat for all rows needing lock-up.

Loss of Control and Sharp Object Hazard:
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.
