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.
120
Be Familiar with Safety Decals
▲ Read and understand “Safety Decals”onpage6,
thoroughly.
▲ Read all instructions noted on the decals.
▲ Keep decals clean. Replace damaged, faded and illegible
decals.

Wear Protective Equipment
Great Plains advises all users of chemical pesticides or
herbicides to use the following personal safety
equipment.
▲ Waterproof, wide-brimmed hat
▲ Face shield, goggles or full face respirator.
▲ Goggles with side shields or a full face respirator is
required if handling or applying dusts, wettable powders, or
granules.
▲ Cartridge-type respirator approved for pesticide vapors
unless label specifies another type of respirator.
▲ Waterproof apron.
▲ Waterproof, unlined gloves. Neoprene gloves are
recommended.
▲ Cloth coveralls/outer clothing changed daily; waterproof
items if there is a chance of becoming wet with spray
▲ Waterproof boots or foot coverings
▲ Do not wear contaminated clothing. Wash protective
clothing and equipment with soap and water after each use.
Personal clothing must be laundered separately from
household articles.
▲ Clothing contaminated with certain pesticides may need to
be destroyed according to national or local regulations.
Read chemical label for specific instructions.
▲ Wear clothing and equipment appropriate for the job. Avoid
loose-fitting clothing.
▲ Prolonged exposure to loud noise can cause hearing
impairment or loss. Wear suitable hearing protection such
as earmuffs or earplugs.
▲ Avoid wearing entertainment headphones while operating
machinery. Operating equipment safely requires the full
attention of the operator.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury. This planter requires a
Power-Beyond port, which is always under pressure
when the tractor is running.
▲ Avoid the hazard by relieving pressure at other remotes, and
shutting down tractor before connecting, disconnecting or
inspecting hydraulic lines.
▲ Use a piece of paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
▲ Wear protective gloves and safety glasses or goggles when
working with hydraulic systems.
▲ If an accident occurs, seek immediate medical assistance
from a physician familiar with this type of injury.
401-755M Table of Contents Index 02/23/2011
Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3
Use A Safety Chain
▲ Use a safety chain to help control drawn machinery should
it separate from tractor draw-bar.
▲ Use a chain with a strength rating equal to or greater than
the gross weight of towed machinery.
▲ Attach chain to tractor draw-bar support or specified
anchor location. Allow only enough slack in chain for turns.
▲ Replace chain if any links or end fittings are broken,
stretched or damaged.
▲ Do not use safety chain for towing.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
▲ Never allow children to operate equipment.
▲ Keep all bystanders away from machine during operation.
Use Safety Lights and Devices
Slow-moving tractors and towed implements can create
a hazard when driven on public roads. They are difficult
to see, especially at night.
▲ Use flashing warning lights and turn signals whenever
driving on public roads.
▲ Use lights and devices provided with implement.
Transport Machinery Safely
Maximum transport speed for implement is 32 kph,
22 kph in turns. Some rough terrains require a slower
speed. Sudden braking can cause a towed load to
swerve and upset.
▲ Do not exceed 32 kph. Never travel at a speed which does
not allow adequate control of steering and stopping. Reduce
speed if towed load is not equipped with brakes.
▲ Comply with state and local laws.
▲ Do not tow an implement that, when fully loaded, weighs
more than 1.5 times the weight of towing vehicle.
▲ Carry reflectors or flags to mark planter in case of
breakdown on the road.
▲ Keep clear of overhead power lines and other obstructions
when transporting. Refer to transport dimensions under
“Specifications and Capacities” on page 102.
▲ Do not fold or unfold the planter while the tractor is
moving.

Hitching Tractor to Planter
The planter has a Category IVa hitch. The
YP625TD12TR110 and YP625TD18TP110, which have
lift-assist, are normally hitched as 2-point semi-mounted.
The YP925TD0965 uses full 3-point hitching.
Crushing Hazard:
Do not stand or place any body part between planter and
moving tractor. You may be severely injured or killed by being
crushed between the tractor and planter. Stop tractor engine
and set parking brake before attaching cables and hoses.
1. To prevent soil compaction on rows, set tractor wheel
center-to-center spacing to place wheels between
planter rows. For hillsides and steep slopes, set
tractor wheels as wide as possible for stability.
Refer to Figure 3
2. Adjust tractor lower links to maximize lifting height.
3. Set tractor sway blocks to minimize side sway. Set
tractor hitch lift control to Float.
4. Back tractor up to planter. Align lower links with the
lower hitch pins on planter.
5. For planter model YP925TD0965, align upper link
with upper 3-point pin holes on planter. Insert or
relocate upper pin (not shown) as needed.
6. Raise tractor 3-point hitch until parking stand base
plates are slightly above ground.
7. Remove the pin in each parking stand. Slide the
stand up in the mount, and re-pin using one of the
holes near the base plate.

Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Shut down tractor before making hydraulic connections.
Only trained personnel should work with system hydraulics.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. If an accident
occurs, seek immediate medical assistance from a physician
familiar with this type of injury.
Use paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems.
Refer to Figure 5
Hydraulic hoses are color coded to help you hookup
hoses to your tractor outlets. Hoses that go to the same
remote valve have coded ties with the same color.
Color Hydraulic Function
Black Fan
Green Marker (Option)
Blue Lift (2-Point semi-mounted planters)
Refer to Figure 5
To distinguish hoses on the same hydraulic circuit, refer
to the cylinder symbols on the clamps.
• The hose under an extended-cylinder symbol feeds a
cylinder base end or motor return line.
• The hose under a retracted-cylinder symbol feeds a
cylinder rod end, or motor pressure line.
Low Population Risk:
If the fan motor hose connections are reversed (relative to
operator expectations), the fan motor runs in reverse, but at a
speed and air flow too low for correct seed metering.
Secure hoses and cables so that they have sufficient
slack for hitch movements, but cannot get caught
between moving parts of planter. Failure to safely route
and secure hoses and cables could result in damage
requiring component repair/replacement, and lost field
time.

Leveling Planter
For row units to function correctly, planter must be:
• level from side to side,
• level from front to back, and;
• at correct tool bar height.
Perform this setup on level ground in representative field
conditions.
Refer to Figure 6
1. Raise planter so that gauge wheels are just off
ground.
2. At each gauge wheel, measure the pre-compressed,
no-load length of the yoke spring .
1
Both axles and yokes should be in the same (upper
or lower) arm and mount holes. All springs should
have this same length. Note this length for step 9.
1
See page 49 for factory setting, and adjustments for
local conditions.
3. Check tire pressures of gauge wheels. As
necessary, inflate to specifications (page 106).
Refer to Figure 7
4. Measure height from bottom of main tool bar to
2
ground, at each end. If this dimension differs by
more than 6.4 mm at each end, adjust lower links of
tractor to level side-to-side.
Note the current height for step 7, and what lowering
would be required to make that 66 cm.
5. Check front-to-back level at top of main tool bar. If
unlevel, adjust top of tractor three-point to level.
6. Pull forward slowly, and lower the planter to
approximately 66 cm. Stop the tractor and set the
parking brake.
7. Check the tool bar height . Adjust the hitch height
2
until it is 66 cm. If available, set a hitch stop control to
capture this height.
8. Check that the row units are running level with the
ground.
9. Check that the gauge wheels are all in solid ground
contact, tires slightly compressed, and that the
springs are slightly compressed from the length
checked at step 2.
Hitch hydraulic circuit configuration during planting can
vary between tractor models, and due to field conditions.
Great Plains recommends starting with the hitch set to
Float or Position/Depth Control (and not Load Control or
Draft Control).

Monitor Setup
Refer to Figure 18
The standard DICKEY-john® PM400 system monitors
the following elements of a YP625TD and YP925TD
planter:
• Seeds at each row unit seed tube.
• Ground speed.
See “Seed Monitor Console Installation” on page 116.
Refer to the DICKEY-john
®
DICKEY-john
PM300-332-400 Planter Monitor Operator’s Manual
(11001-1372) for monitor operations.
After installation, and prior to first field use, the monitor
must be setup with the row spacing and speed sensor
constant, as well as your preferences for information
display. Row count is auto-assigned, but any other
DICKEY-john® defaults are not likely to be correct for
your planter.
Row spacing data may be found in the Appendix.
For speed setup, Great Plains recommends using the
122m (400-foot) calibration described in the
DICKEY-john® manual, rather than using the theoretical
“# of pulses” from Appendix B. Perform the calibration
run in representative field conditions, as soil conditions,
surface looseness and other tillage practices can cause
variations in the effective rolling radius of the ground
drive wheel.
Prior to each planting session, set any desired limits for
speed and population for the current crop.

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 following steps before transporting the
YP625TD & YP925TD planter to the field.
❑ Carefully read “Important Safety Information” on
page 1.
❑ Treated seed, or fertilizer: Review the application
instructions and Material Safety Data Sheet (MSDS)
for the seed and/or fertilizer.
❑ Install seed disks appropriate for crop. See “Air-Pro
Meter Disk Installation” on page 59.
❑ Lubricate planter as indicated under “Lubrication”
on page 89.
❑ Check all tires for proper inflation. See “Tire
Inflation Chart” on page 106.
❑ Check all bolts, pins, and fasteners. Torque as
shown in “Torque Values Chart” on page 106.
❑ Check planter for worn or damaged parts. Repair or
replace parts before going to the field.
❑ Check hydraulic hoses, fittings, and cylinders for
leaks. Repair or replace before going to the field.
High Pressure Fluid Hazard:
Relieve pressure and shut down tractor before connecting,
disconnecting or checking hydraulic lines. Use a piece of
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. Escaping fluid under pressure
®
can have sufficient pressure to penetrate the skin causing
serious injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.

Raising/Lowering Planter
A 3-point planter is raised and lowered using the tractor
3-point hitch.
A 2-point/lift-assist planter is raised using the 3-point
hitch in front, and the hydraulic lift assist cylinder at the
rear of the planter.
When lowering in field conditions, drive forward while
lowering openers into ground. Never back up with
openers in ground.
Hitch hydraulic circuit configuration during planting can
vary between tractor models, and due to field conditions.
Great Plains recommends starting with the hitch set to
Float or Position/Depth Control (and not Load Control or
Draft Control).
Lift Locks
Use parking stands (page 15) to hold front of implement
at raised for parking, maintenance and storage. Raise
parking stands for transport.
On twin- and triple-row models, use the lift-assist cylinder
lock to hold the planter rear at raised for transport,
parking, maintenance and storage.
Refer to Figure 9
To install the cylinder lock channel:
1. Remove pin and lock channel from storage hole
in right side of lift-assist weldment.
2. Raise planter to transport position (page 20). Set lift
circuit to Neutral to hold at raised.
3. Install lock channel on cylinder rod. Secure with pin.
4. If parking, storing or performing maintenance or
adjustments, lower parking stands (page 15).
5. Lower planter onto stands and lock channel.
Raise planter, and hold at raised, before removing lock
channel.
1 2
Machine Damage Risks:
Always fold markers (page 33) before raising or lowering.
Always raise the planter for any reverse/backing.
Except on pavement, begin forward motion before lowering, as
rows move backward slightly as arms swing up.

1. Typical: Coulters. No Markers or Row Cleaners.
2. Maximum: Coulters, Row Cleaners, Markers.
Transport
Loss of Control Hazard:
Do not transport with insufficient ballast or with an
inadequate tractor.
Check that your tractor has enough ballast for the weight of
the drill. A tractor with insufficient ballast has insufficient
traction at the front wheels, causing loss of control, leading to
a serious road accident, injury or death. Refer to your tractor
operator manual for ballast requirements.
Check that tractor is rated for the fully-ballasted load. An
inadequate tractor may be damaged by over-loading. It is also
at risk for loss of control in turns and braking, leading to a
serious road accident, injury or death.
The planter can weigh nearly 7000 kg, depending on
configuration and material load. The tractor MUST be
rated and ballasted for the load. Do not tow if planter
exceeds the load rating of the vehicle. See chart at right
for typical configuration weights.
Braking and Loss of Control Hazard:
Do not exceed 32 kph.
Reduction of Control Risk:
Seed and fertilizer may be loaded prior to travel, but increase
stopping distance, increase the need for caution in turns and
braking, and increase tire wear.

Transport Steps
Transport only with markers stowed (page 33).
1. Check that planter is securely hitched to a sufficient
tractor (page 15).
2. Verify correct operation of lights.
3. Fold markers if unfolded (Option, page 33).
4. Raise planter (page 20).
5. Raise parking stands (page 15).
6. If the planter has lift-assist, install the cylinder lock
(page 20).
7. Unload seed and fertilizer hoppers before
transporting if at all possible. The planter can be
transported with a full material load, but the added
weight increases stopping distance and decreases
maneuverability.
Increased Hazards and Wear Risks:
Seed may be loaded prior to travel, but increases stopping
distance, increases the need for caution in turns and braking,
and increases tire wear.
8. If any seed is in hoppers or delivery hoses, close
seed inlet shutters at meters (page 60).
9. Check that tires are properly inflated (page 106).
10. Plan the route. Avoid steep hills.
11. Always have lights on for highway operation.
12. Do not exceed 32 kph. Comply with all national,
regional and local laws when traveling on public
roads.
13. Remember that the planter may be wider than the
tractor or towing vehicle. Allow safe clearance.
14. Transport slowly over uneven or rough terrain.

Hopper Operations
Refer to Figure 10 and Figure 11
Hopper lids have distinct ends:
• the hinge end (with two lugs) mates with the front
end of the hopper.
• the latch end (with a single lug) mates with the rear
end of the hopper.
To open a hopper:
1. Pull the rear of the lid edge to the rear.
2. Swing the lid up at rear.
3. Disengage the lid at the front lugs.
4. Park the lid on the front lip of the hopper, using the
hook-plate feature inside the lid (see Figure 12 on
page 24).

Possible Agricultural Chemical Hazards:
Read and follow all supplier cautions for safe handling of
treated seed.
Irritant and Chronic Exposure Hazards:
Do not mix lubricants into seed with hands or any part of
body. Wear protective equipment. Use tools. See page 96.
11. Pre-mix seed and lubricant. For clean seeds other
than milo, sprinkle Ezee Glide Plus seed lubricant at
a rate of 71 ml per 42 liters (one hopper) of seed.
For milo, double the application to 142 ml (or more)
per 42 liters of seed.
Figure 12
Adding Seed Lubricant
29976
Population Risk:
The seed must be properly lubricated, starting with the first
seed through the meter. If unable to pre-mix prior to loading,
pre-mix at least 4 liters of seed per hopper, and load this seed
first. Fill the hoppers to half full with fresh seed. Add half the
lubricant and stir. Complete filling the hoppers and sprinkle
the remaining lubricant on top.
12. Add seed and lubricant to hoppers.
Refer to Figure 10 and Figure 11 on page 23
13. Close lids. With lid tilted up at a slight angle, hook
the two front hinge lugs under the front hopper lip.
Swing down, keeping fingers clear of lug, and latch
the single rear lid lug on rear hopper lip.
Equipment Loss Risk:
Check that all 3 lid lugs are completely under the hopper lip,
or the lid may come off in transport.

Great Plains Manufacturing, Inc. Table of Contents Index Operating Instructions 25
Loading Dry Fertilizer
If fertilizer will not be applied, uncouple the fertilizer
meter shaft at the left end of the left hopper. Pin the
coupler clear of the shaft joint.
Loading fertilizer prior to transport is not recommended.
Although the meters are not turning during transport, it is
possible for some material to spill through the meters,
particularly on rough roads.
Suitable Materials
Use only dry granular fertilizer. Granules must flow freely,
and must have a maximum diameter smaller than 7 mm
(to avoid bridging clogs in the applicator tube outlets).
Agricultural Chemical Hazard:
Wear protective equipment suitable for the material to be used,
and the material previously dispensed from the hoppers. Avoid
contact with skin or eyes. Avoid breathing dust.
System Inspection
Verify that both rear cradle pins are installed on all
hoppers. See Figure 81 on page 79.
Refer to Figure 13
Remove the lid on each hopper and inspect for:
• residual fertilizer incompatible with next use
• contaminants
• debris that might clog the meter inlets
• trapped animals, lost tools, etc.
If it is necessary to clean a hopper, see “Dry Fertilizer
Clean-Out” on page 79.
Hopper Lid Operation
Refer to Figure 14 and Figure 16
To unlock the hopper lid, lift the rubber latches out of
the metal keepers .
Note: The keeper hardware tends to snag under the
hopper lip. Pull the lid edge forward and lift.
Refer to Figure 15
To open the lid, lift the front edge up and slide the lid
back into a vertical position behind the hopper. The lid is
held by retaining straps .

(If only the handle “T” is seated, the lid is not secure.)
Dry Fertilizer Operation
Great Plains recommends checking with your local
agronomist prior to setting the rate, as soil conditions
vary.
The fertilizer meters are driven from the same ground
drive that powers the seed metering system. When the
planter is lowered and in motion, the meters operate, and
fertilizer is applied based on the rate controlled by the
selection of fertilizer transmission sprockets.
See the Seed and Fertilizer Rate manual (401-754B)
for rate charts and detailed information on rate setting.
The outlets of the fertilizer meters are normally
connected to fertilizer drop tubes at the dry fertilizer
coulters. See page 46 for adjustment of drop tube height
and angle.
Refer to Figure 17
If fertilizer will not be applied, disengage the drive
coupler at the left end of the left fertilizer hopper:
1. Remove the pin from the coupler .
2. Slide the coupler left, completely off the driven
shaft , and clear of both the shaft gap and the pin
3
hole in the driving shaft .
3. Re-insert the pin in the driving shaft (not through the
coupler). Secure pin to shaft with wire bail.
To restore fertilizer drive operation, first rotate the driven
shaft to align its pin hole with the hole in the coupler.
Slide the coupler right. Re-insert pin through both
coupler and driven shaft. Secure pin with wire bail.
