Implement Locks
The Nutri-Pro
®
NP4000 Applicator is equipped with
several lock systems, which provide safety and/or
operational functions. Manual and manual reset locks
require operator intervention for specific tasks. Automatic
locks require no intervention, but you may need to be
aware of their function.
Lift-Assist Lock Channels
Refer to Figure 14
These 11 inch (28 cm) length manual lock channels
are installed on the rear lift-assist cylinders for
adjustments, transport, parking, storage and raised
servicing. The locks are held in place by a bent pin
.
Fully raise the implement (page 35) to install or remove
the channels at the cylinder rods.
When not in use, the channels are stored on tubes
on
the caster side faces.
Outer Wing Lock Channels
Refer to Figure 15 and Figure 16
These 20
1
⁄
4
inch (51.4 cm) manual lock channels
are
installed on the outer wing fold cylinders
only for field
operations. They (and the inner wing locks) provide stops
limiting fold during lift for field turns. The locks are held in
place by a bent pin
. See “Unfolding and Folding” on
Fully unfold the implement (page 37) to install or remove
these locks.
Note: If the outer wing has not fully unfolded due to
ground contact, pull forward to bring wings level.
When not installed, the outer wing locks may be stored at
the mounting tab
on the wing rest stops.
Note: Be sure to use the 20

inch (51.4 cm) locks on the
outer wing cylinders, and not the 11 inch (28 cm)
lift-assist locks.
Wing Lock Pins
Refer to Figure 16
These pins
are manually inserted after fold, both as a
safety precaution, and to minimize wing-cradle impacts
during transport.
When not engaged, the pins are stored in tubes
at the
base of the rest weldment.
