Application Overview
Tank, plumbing and setup requirements differ for ground
drive and hydraulic drive applicators. The next few pages
provide an overview of both systems. Note: Callouts 11 to 50, correspond to the items
beginning below, and identify the same
components throughout this manual.
Implement System Components
This list presumes that the implement has system
components factory-installed by Great Plains. The list
includes all components for either the preset or hydraulic
drive pumping system.
If the implement has aftermarket components, part or all
of this information may not apply to your operations.
Consult the manual or other documentation for your tank
or pump.
Refer to Figure 3 on page 17 and Figure 4 on page 18
11. Application Tank
Tank Option: The system depicted shows the
optional twin 300 gallon tanks, which includes the
quick-fill inlet assembly. A user-provisioned fertilizer
supply tank may be a trailing nurse tank cart, or may
be tractor-mounted.
A trailing nurse tank cart requires the optional nurse
tank hitch (page 98) on the implement. The cart
must be full-trailering, and not semi-mounted. The
Great Plains plumbing systems are not
pre-configured for user-provisioned tanks.
12. Vented Tank Lid
Tank Option: A fully sealed tank must be vented
during operation. If the tank has a control for this, it
may be part of the top tank lid, or a separate
valve.Each on-board tank has a 10in vented
screw-on lid. Tanks may be filled at the top or via the
quick fill
.
13. Tank Discharge Valves
Tank Option: Each on-board tank has its own valve,
which switches the tank discharge port between
these states:
tank connected to selector valve
tank discharge closed (shut off at valve)
tank connected to tank drain elbow
Discharge valves are normally open to the selector.
The may be closed individually to prevent
tank-to-tank transfer on slopes.
14. Tank Drain Elbow
Tank Option: This open elbow fitting is used for
material recovery and tank wash-out (page 79).
15. Selector Valve
Tank Option: This valve is included with the optional
on-board tank system. The valve switches the tank
plumbing between three states:
tank plumbing connected to inlet
tank plumbing shut off at valve
tank plumbing connected to pump system (
, )
16. Supply Inlet
Tank Option: With the optional on-board tanks, or
without the tanks, but with the trailer hitch option, the
inlet of the NP4000 applicator is a 2 inch cam-lock
quick coupler receptacle (female, FCL). The tank
supply hose fitting must be, or be adapted to 2in
MCL.
17. Inlet Shut-Off Valve
Tank Option: This valve is open only during tank
filling with on-board tanks. This valve is
customer-provisioned for tractor-mounted or trailing
nurse tank configurations.
18. Strainer
Tank Option: This fitting contains an 80 mesh screen
for filtering large particles and coagulates in the
fertilizer, preventing blockage at the orifice plates
.
See page 69 for alternative screen sizes and
page 80 for maintenance.
19. Ground Drive Pump
Ground Drive Option: The CDS-John Blue
NGP-7055-K has a capacity of 34 gallons/minute
(129 liters/minute). See the 12-M-43 CDS-John Blue
NGP Pump Parts and Instructional manual for
maintenance.
20. Pump Adjustment Dial
Ground Drive Option: This 0-to-10 adjustment sets
the percentage of rated gpm/lpm to use. Settings
below 2 are not recommended.
Pump and application rate are set by a combination
of ground drive sprockets (not shown) and dial
setting. See page 64 for ground drive rate setting.
System Clogging Risk:
Use only pre-mixed liquid fertilizer. Regardless of the tank
type used, or its capabilities, do not use dry fertilizer
mixes with the Nutri-Pro
®
applicator.
