Liquid System Narrative
Tank, plumbing and setup requirements differ for ground
drive and hydraulic drive applicators. The next few pages
provide an overview of both systems.
Refer to Figure 6 on page 29 and Figure 5 on page 28
Note: Callouts L11 to L51, correspond to the items
beginning below, and identify the same
components throughout this manual.
This list presumes that the applicator has system
components factory-installed by Great Plains. The list
includes all components for either the preset or hydraulic
drive pumping system.
If the applicator 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.
L11. 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 139) on the applicator. The cart
must be full-trailering, and not semi-mounted. The
Great Plains plumbing systems are not
pre-configured for user-provisioned tanks.
L12. 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 10 inch vented
screw-on lid. Tanks may be filled at the top or via the
quick fill
.
L13. 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.
L14. Tank Drain Elbow
Tank Option: This open elbow fitting is used for
material recovery and tank wash-out (page 118).
L15. 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 connected to pump system (
,
)
L16. Supply Inlet
Tank Option: With the optional on-board tanks, or
without the tanks, but with the trailer hitch option,
the inlet of the NP3000 applicator is a 2 inch
cam-lock quick coupler receptacle (female, FCL).
The tank supply hose fitting must be, or be adapted
to 2 inch MCL.
L17. 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.
L18. 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 91 for alternative screen sizes
and page 119 for maintenance.
L19. 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.
L20. 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 88 for ground drive rate setting.
L21. Pump Adjustment Tool
Ground Drive Option: Adjusting the setting dial may
require some mechanical assistance. A slot is
provided to store the tool at the pump when not
being used for adjustments.
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.
