Operating Instructions
SML Cart Tank Fertilizer System Elements
Liquid fertilizer system callouts are consistent across
this entire manual. No single system includes all
elements.
Tank lids are vented and may be kept tight. Lids have a
removable center section for easier hose fill.
Cart tanks is 500, 735 or 1000 gallons (1900, 2800 or
3750 liters) each. A sight gauge at one end shows
current fill level against a scale.
This valve is normally left open.
This 2 inch fitting secures either the plug or the fitting of
an external hose using cam locks. Always close the
valve
before removing the plug.
This valve is opened for filling tanks from a pressurized
supply source.
This fitting containers an element to trap coarse debris
in the material. Reverse flow through this strainer is not
recommended.
The centrifugal pump is powered by a hydraulic motor
controlled by a proportional valve (not shown). The
valve is controlled by the seed monitor.
The pump normally operates at a flow rate higher than
required for the booms. The pump output is split into a
boom flow, and a recirculation/bleed flow.
This small line provides pump priming and recirculation
of excess material afield.
Remove this plug to drain or flush the bleed line or
pump.
This valve is normally open. It may be closed for
reduced bypass at very high application rates.
Recirculation Lines to Tank(s)
This line provides pump priming and recirculation of
excess material afield.
This valve is normally open. It might be closed for
maintenance.
This valve protects the system from damage in the
event of overpressure due to blockage or valve
misconfiguration. Above approximately 65 psi, excess
material is returned to both the pump and the tanks.
This line returns the majority of any overpressure
excess material to the tanks.
This valve sets the boom flow side of the pump outlet to
boom, off or off-load. A decal on the mount indicates
handle positions.
A filter element in the canister traps large particles that
might clog boom orifice plates. See the Seed Rate
manual for maintenance and alternate element screen
sizes.
Normally open, this valve isolates the boom side of the
strainer for servicing.
This valve is open for field application and normally
closed at all other times.
This valve is open for field application and normally
closed at all other times.
This fitting measures material flow to the boom.
Readings from this sensor are used by the seed
monitor to adjust the pump rate.
This valve is normally open. It might be closed for
maintenance.
There are separate boom sections for the planter center
section and each wing.
There are separate boom sections for the planter center
section and each wing.
Boom taps are provided for at least the number of rows
present.
The standard fitting on an active row is a nozzle body
that accepts various size orifice plates.
The orifice plate
sits inside this rubber seal.
These stainless steel plates have precisely sized center
holes that provide flow resistance for optimum boom
pressure. They do not regulate flow rate, but must be
sized to the flow rate.Standard booms include sizes 24,
34 and 48.
These optional nozzles are an alternative to changing
orifice plates. They are spring loaded to maintain a
constant back-pressure over a wide range of rates.
Any unused boom clamps are provisioned with caps
instead of nozzles. Caps may also be used to shut off
rows when changing row spacing.
Each boom section has at least one end cap. These are
removed for flushing booms, such as for winterizing.
Each active nozzle is connected to the row applicator
via tubing.
All standard 25 Series row units include an applicator
tube which can deliver material in-furrow just ahead of
the seed tube. Optional Keeton
®
seed firmers (shown)
have a delivery tube for applying material behind the
seed tube.
