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 47
When not in use, lock-up pins are normally stored in a
hole
at the top of the opener mount.
It is generally easier to lock up a rear row unit.
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 be set to the
minimum setting, per the instructions on page 51.
Refer to Figure 48
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 shank,
b. use a jack under the shank extension, or;
c. place a block under the row, and lower drill.
Do not pin the row unit while it is in the lowered position. If
the pin is inserted below the parallel arm, 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.
Uncouple meter drives for the locked-up rows. Pull
shaft out and park pin in shallow detents (page 55).
Do not disable meters by removing them, unless you also com-
pletely remove the chain, or the chain will cause machine dam-
age.
7.
Repeat for all rows needing lock-up.
8.
Reset marker extension (page 25).
9.
Reset seed monitor active row pattern and row
spacing to avoid nuisance alarms.
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.
