Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations,
typically for machine components that, for functional
purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe
practices.
Prepare for Emergencies
▲ Be prepared if a fire starts.
▲ Keep a first aid kit and fire extinguisher handy.
▲ Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals” on page 4,
thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.

Wear Protective Equipment
Great Plains advises use of the following personal safety
equipment.
▲ Hearing protection, such as earmuffs or earplugs, for
making planter adjustments with the hydraulic fan
running.Prolonged exposure to loud noise can cause
hearing impairment or loss.
Avoid wearing entertainment headphones while operating
machinery. Operating equipment safely requires the full
attention of the operator.
▲ Face shield, goggles or full face respirator when handling
treated seed, seed lubricants or seed treatment.
▲ Gloves for working near sharp objects, and for handing
lubricants or treatments.
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
▲ Read and follow chemical supplier instructions.
▲ Wear protective clothing.
▲ Handle all chemicals with care.
▲ Agricultural chemicals can be dangerous. Improper use can
seriously injure persons, animals, plants, soil and property.
▲ Inhaling smoke from any type of chemical fire is a serious
health hazard.
▲ Store or dispose of unused chemicals as specified by the
chemical manufacturer.
▲ If chemical is swallowed, carefully follow the chemical
manufacturer’s recommendations and consult with a doctor.
▲ If persons are exposed to a chemical in a way that could
affect their health, consult a doctor immediately with the
chemical label or container in hand. Any delay could cause
serious illness or death.
▲ Dispose of empty chemical containers properly. By law
rinsing of the used chemical container must be repeated
three times. Puncture the container to prevent future use. An
alternative is to jet-rinse or pressure rinse the container.
▲ Wash hands and face before eating after working with
chemicals. Shower as soon as application is completed for
the day.
▲ Apply only with acceptable wind conditions. Wind speed
must be below 8 kph (5 mph). Make sure wind drift of

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Confined Space
With materials loaded, or once used for hazardous
fertilizers, or seeds with hazardous treatments, your
fertilizer hopper may become a
“permit-required confined space”
under applicable statutes, regulations, insurance rules or
business policy. The vent tube structure in the hopper
has features to assist escape, and is not for routine entry.
▲ A hopper that is full or merely appears full can be an
entrapment hazard. You can sink entirely into the material,
or into an oxygen-deficient void, and suffocate in a matter of
seconds. Fertilizer bridges and crusts are especially
dangerous.
▲ When hazardous fumes are present, you can be quickly
overcome even with the hopper lid open.
▲ Do not enter a hopper for material loading, material
unloading, hopper cleaning or meter maintenance.
▲ Clean hopper by power washing from outside hopper top.
▲ Perform meter maintenance by removing meter from bottom
of empty hopper.
▲ If obstruction removal or repair requires hopper entry, have
the work performed by a team trained in confined space
procedures. See “Hopper Entry” on page 37.
Practice Safe Maintenance
▲ Understand procedure before doing work. Use proper
tools and equipment. Refer to this manual for additional
information.
▲ Work in a clean, dry area.
▲ Lower the planter, put tractor in park, turn off engine, and
remove key before performing maintenance.
▲ Make sure all moving parts have stopped and all system
pressure is relieved.
▲ Allow planter to cool completely.
▲ Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on planter.
▲ Inspect all parts. Make sure parts are in good condition
and installed properly.
▲ Remove buildup of grease, oil or debris.
▲ Remove all tools and unused parts from planter before
operation.

Preparation and Setup
This section helps you prepare the dry fertilizer feature of
your YP2425F-2470, YP4025F-1630 and YP4025F-1670
planter for use, and covers tasks that need to be done
seasonally, or when the tractor/planter configuration
changes.
Before using the planter in the field, you must hitch it to a
suitable tractor, inspect systems and level the planter,
per the instructions in the 401-406M (YP2425) or
401-571M (YP4025) Operator manual. Before using the
planter for the first time, and periodically thereafter,
certain adjustments and calibrations are required. See
the Operator manual for these procedures.
Initial Setup
See the Operator manual, Appendix B, for pre-delivery
and first-time setup items for the basic planter.
First-time/infrequent setup tasks for the
YP24/YP40 DF/seeder feature include:
• Verify monitor setup (page 53 in this manual).
Post-Delivery/Seasonal Setup
On initial delivery, use with a new tractor, and seasonally,
check and as necessary, complete these items before
continuing to the routine setup items:
• Inspect fertilizer meter door seals for leaks or wear.
• Inspect fertilizer meter flutes for damage or wear.
Hitching and Leveling
The YP24/YP40 DF/seeder feature causes no changes
to the hitching procedures described in the planter
Operator manual.

Operating Instructions
This section covers general operating procedures.
Experience, machine familiarity, and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
Pre-Start Checklist
Perform the planter pre-start checklist, and the following
steps before transporting the YP24/YP40 DF/seeder
planter to the field. Add this item:
❑ Check for air system leaks at the fertilizer hopper lid,
meter, inlet and outlet manifolds.
Planter Folding and Raising
The YP24/YP40 DF/seeder feature does not affect
raising/lowering, folding/unfolding or tongue operations.
Material Loss Risk
The fertilizer ground drive operates whenever the planter is
lowered and in forward motion. If fertilizer application is not
desired (for example, during speed calibration or row unit
adjustment testing), take any of these steps to prevent fertilizer
metering:
▲ Tie ground drive wheel up out of ground contact.
▲ Remove a chain in the ground drive.
▲ Set meter gearbox adjuster to zero. Do this only on a
temporary basis, such as speed calibration.
▲ Defer loading of fertilizer until after speed calibration or
other non-application lowered movement.

10 YP2425F/YP4025F Table of Contents Index Great Plains Manufacturing, Inc.
Transport
Loss of Control Hazard:
Ensure that the towing vehicle is adequate for the task. Using
an inadequate tow vehicle is extremely unsafe, and can result
in loss of control, serious injury and death.
21
The planter can weigh over 15 000 kg (33,500 pounds),
depending on configuration and material load. The tractor
unit MUST be rated for the load. If the tractor is not rated for
at least 15 000 kg, calculate or obtain a scale weight of the
planter.
Do not tow if planter exceeds the load rating of the vehicle.
Braking and Loss of Control Hazard:
Do not exceed 20 mph (32 kph).
5
Reduction of Control Risk:
Material loaded prior to travel increases stopping distance,
and increases the need for caution in turns and braking.

apply to the YP2425F-2470, YP4025F-1630 and
YP4025F-1670. Using a standard 82bu hopper requires
substantial disassembly of the planter seed cart
structure, and modifications to the air system. Using a
150bu hopper or dual 200 gallon liquid fertilizer system
further requires removal of the entire fertilizer ground
drive. Such conversions are not documented or
recommended.

Seeding System Overview
Refer to Figure 5 on page 14
1. Hydraulic Fan:
The hydraulic fan supplies air for both seed and
fertilizer delivery. Fan rpm is operator-adjusted via
the tractor circuit’s hydraulic flow control.
2. Fan RPM Sensor:
Fan rpm is measured by a sensor mounted inside
the fan cage, and reported on the seed monitor
console.
3. Butterfly Valve (Seed Leg):
Manually-adjusted butterfly valves are provided on
the splitter at the fan outlet. The valve on the left leg
controls air for the seeding system. See page 19 for
valve adjustment.
4. Air Box Air Inlet:
Fan air enters the air box at the manifold inlet and is
mixed with seed.
5. Seed Hopper:
The rear hopper is the seed hopper. See “Loading
Seed” on page 11. The hopper contains a
pressure-balancing system (not shown) to help
prevent seed bridging.
6. Slide Gate:
There is a slide gate at the base of the seed hopper,
used to shut off seed flow during transport,
maintenance and storage.
7. Air Box Seed Inlet:
Seed enters the air box manifold at the top.
8. Seed Level Sensor:
The inlet contains a level sensor. When this sensor is
exposed (seed level below sensor), there may be
less than a hectare of seed remaining.
9. Seed Manifold Outlets:
The fan airflow entrains seed inside the air box, and
exits at the manifold outlets. On this model planter,
there is one outlet port per row.
10. Seed Hoses:
Seed hoses deliver seed to the rows. On this model
planter, there is one hose per row, and no Y-tube
splitters.
11. Air Release Vents:
The meter inlets contain a venting system to exhaust
the delivery air. When seed backs up above the vent,
seed flow to that row stops until the meter has
consumed enough seed to re-expose the vent.
12. Seed Meter:
The Singulator Plus®or finger pickup meter contains
a seed wheel or finger-set that capture seeds at a
precise rate.
13. Seed Meter Drive:
Meter rotation is coupled to the drive system, which
is powered by a hydraulic motor (not shown) under
control of the seed monitor. Clutches control drive
shafts for entire planter sections. See planter
Operator manual for clutch operation.
Note: Seeding rate is independent of air system
operation, if the air system is set to provide
enough bulk seed flow to keep the meters full, but
not so much flow that system plugging occurs.
See page 19 for fan operation.
Note: A coupler at the meter may be disengaged to shut
off seeding at that row. See planter Operator
manual for row shut off. Fertilizer application
cannot be shut off at individual rows.
14. Seed Tube:
The seed wheel or finger set deposits seed in the
row’s seed tube, for delivery to the furrow.
15. Seed Sensor:
In the seed tube, the seed sensor detects passage of
seeds. Medium size and large seeds are counted
individually. With smaller seeds, most are detected,
allowing the monitor to detect stoppages.

Fertilizer System Overview
Refer to Figure 6 on page 16
1. Hydraulic Fan:
The fan supplies air for both fertilizer and seed
delivery. Fan rpm is operator-adjusted via the tractor
circuit’s hydraulic flow control.
2. Fan RPM Sensor:
Fan rpm is measured by a sensor mounted inside
the fan cage, and reported on the seed monitor
console.
3. Butterfly Valve (Fertilizer Leg):
Manually-adjusted butterfly valves are provided on
the splitter at the fan outlet. The valve on the right leg
controls air for the fertilizer system. See page 19 for
valve adjustment.
4. Fertilizer Air Inlet Manifold:
Fan air is divided into six equal flows at the inlet
manifold.
5. Fertilizer Hopper:
The front hopper is the fertilizer hopper. See
“Loading Fertilizer” on page 12. The hopper
contains a ladder-style pressure-balancing system
(not shown) to help prevent fertilizer bridging.
6. Pressure Sensor:
A sensor in the fertilizer hopper reports air pressure
to the seed monitor, and is reported on the console.
7. Fertilizer Level Sensor:
The fertilizer hopper contains a level sensor. When
this sensor is exposed (fertilizer level below sensor),
approximately 78 liters (2.2 bu) of fertilizer remains.
8. Fertilizer Meter:
The fertilizer meter is at base of the fertilizer hopper.
There is no slide gate. The meter is always open to
the fertilizer hopper.
9. Meter Doors:
The meter box has doors at the bottom for clean-out
(front) and calibration (rear). See page 27 or
page 35. These doors are closed for field operations.
10. Fertilizer RPM Sensor (shaft monitor):
A sensor on the meter flute shaft reports shaft rate to
the seed monitor. The seed monitor does not report
material rate from this data, but can generate alarms
on shaft stoppages or rpm out-of-limits.
11. Range Gears:
Interchangeable Final Range Gears set the coarse
rate of the flute shaft. The meter system is powered
by a ground drive (not shown), which has a variable
rate gearbox for fine adjustment. See page 23.
Fertilizer metering occurs whenever the planter is
lowered and in forward motion.
12. Flute Stars:
Fertilizer is metered into the manifold air stream by
flutes on the final shaft. The four inside
compartments have three flutes (six halves) and feed
3-way towers. The two outside compartments have
two flutes and feed 2-way towers.
Material Mis-Application Risk:
If it is ever necessary to disconnect delivery hoses at the
manifold, it is essential that the hoses to the wing-end
(2-way) towers be connected to the outside ports
(#1 and #6) at the manifold.
13. Fertilizer Manifold Outlets:
The fan airflow from the inlet manifold entrains
metered fertilizer in the chambers below the flutes,
and exits at the manifold outlets. Each outlet serves
a single hose to a single distribution tower, and
multiple rows.
The center four outlets serve 3-way towers.
The outside two outlets serve 2-way towers.
14. 3-way Tower:
Four of the six towers divide the air/fertilizer flow
3ways.
15. 2-Way Tower:
Two of the six towers (the two serving wing end
rows) divide the air/fertilizer flow 2 ways.
16. Vent for 2-Way Towers:
To balance the airflow at all manifold ports, the 2-way
towers vent some of the air at the tower inlet. See
page 43 for maintenance.
17. Blockage Detectors:
Each tower divider outlet is equipped with a material
sensor, connected to the seed monitor and
configured for “Blockage” mode. These report any
flow failure at the rows. See page 54.
18. Coulter Applicators:
Coulters are factory configured for side-dress
fertilizer application, at 5cm (2in) off-row, and a
depth of 5cm (2in), “zone” application. The coulter
has adjustments for depth and the height of the
applicator exit tube.

Fan Circuit Operation
Refer to Figure 7
Three hydraulic hoses serve the fan, and must be
properly connected for the fan to operate in the correct
direction , at recommended speeds, and without
damage. See “Hydraulic Hose Hookup” in the
401-406M (YP24) or 401-571M (YP40) Operator
manual.
1. Always connect the case drain line first.

This line protects the outer shaft seal of the hydraulic
motor. The case drain is a small line to the hitch,
provisioned with a specialized low-seep flat-face
case drain Quick Disconnect. Pressure spikes during
motor operation, and pressure cycles due to
temperature change are bled off by the case drain.
1
Motor Seal Damage Hazard
Do not apply pressure to the case drain line. Do not change the
special QD connector. A restricted or sealed case drain line
will promptly result in motor seal damage.
2. Connect the motor return line second, to sump.

Figure 7
Hydraulics at Fan
31095
The planter includes a 11⁄16in low back-pressure QD
coupler set. Install the receptacle on a tractor sump
port, and not at a normal remote return port. The
unusual size aids in ensuring correct connection, so
that the motor return line handles high volume at low
back-pressure, ensuring full motor performance.
3. Connect the motor inlet line to a tractor remote
4
capable of 95 liters per minute (25 gpm). If a priority
remote is available, use it for the fan.
4. The fan hydraulic circuit includes a check valve ,
5
which provides a relief path for oil at motor shutoff.
If the fan is connected in reverse, flow through this
valve results in low fan rpm, providing strong
indication reversed connection.
Correct fan direction is shown at . If reversed fan is
1
suspected, observe it during shutoff, as the direction
of motion is easier to see at lower rpms as it slows to
a stop (initial startup is virtually instantaneous,
making observation at start difficult).
Fan speed is controlled by the tractor circuit and butterfly
valves (and not the seed monitor).
You may stop the fan by setting the circuit to neutral or
float. The check valve slows the blades to a stop by
locally recirculating the oil.
If the fan is connected in reverse, it may not run at all
(due to no oil source at the return connection). If oil is
present, oil bypass at the check valve prevents the
5
fan from reaching high rpm. A reversed fan may send
some air to the delivery systems, but is incapable of
providing reliable air flow for planting.
Fan speed can change as oil heats to operating
temperature. Re-check fan rpm and hopper pressure
more often during early operations.

Fan General Operating Information
Adjust the fan rpm and butterfly valves to provide
sufficient air flow for consistent transport of seed and dry
fertilizer. Suggested values are shown at right.
Fan rpm is controlled by the tractor circuit, and reported
by the seed monitor. Always start the fan with a low flow
setting. Gradually bring fan up to the target rpm.
Fan air pressure is measured by a sensor in the fertilizer
hopper, and reported by the seed monitor. Air pressure is
controlled by fan rpm, butterfly valve settings, material
density and rates. System settings may vary with
material mix, material density and rates.
Recommend initial butterfly valve setting is 0° (wide
open) at both valves (assuming material application from
both hoppers). If one hopper is unused, set the valve for
that hopper to 30° to simulate the normal back-pressure
of material flow from that hopper.
Butterfly Valves
Use tractor remote hydraulic valve flow control to set fan
speed and butterfly valves to balance flow. Precise
technique depends on tractor capabilities:
• For any setup adjustment, operate the tractor engine
at typical field rpms, and not at idle.
• Preset the butterfly valves. Use any settings that you
previously developed for the material mix and rates,
otherwise:
70°
45°
2
20°
If the tractor has fine control of remote flow rates, and
consistent flow at varying tractor engine rpm, initially
set the butterfly valves to 0°.
If the tractor has only coarse control of flow, initially set
the butterfly valves to 45°.
• Set the fan circuit flow to bring the pressure sensor to
near the recommended value.
• If the tractor has marginal flow available, or the list
circuit has priority, you may need to experiment with
combinations of fan flow and butterfly valve settings.
At excessive rpm, too much air flow can cause:
Symptoms of Insufficient Air Flow
• Excessive skips (low seed population) at seed meters.
• Blockage reported at fertilizer applicators.
• Plugging of delivery hoses at low spots.
Symptoms of Excessive Air Flow
• Blockage reported at openers or coulters.
• Plugging of delivery hoses near air boxes.
• oil heating
• slow lift times

Butterfly Valve Operation:
To adjust, loosen bolt and rotate the handle .
Re-tighten bolt.
0° is wide open - maximum air flow.
90° is closed - minimum air flow.
The valve provides the most effect at settings between
20° and 70°.
Starting at 30° reduces the fan workload.
Starting at 45° provides the most adjustment range up or
Note: If desired pressure cannot be reached, or requires
unusually high oil flow at low butterfly valve
settings, chances are the fan is running
backwards. Reverse the inlet/return lines at the
hitch.
