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.

hitch the planter to a suitable tractor and level the
planter.
Initial Setup
If the planter has just been delivered, or broken down for
re-shipment, these items need to be completed prior to
first field use:
“Appendix C - Initial Setup” on page 156, which
includes:
“Hydraulic Charge and Bleed” page 156,
“Seed Monitor Console Installation” page 156,
“PM400 Monitor Quick-Start” page 157,
“Level Planter” page 159,
“Wing Alignment” page 160,
“Speed Calibration” page 161, and
“Marker Extension” on page 161.
You may also need to install features, options and
accessories that were not factory- or dealer-installed.
Pre-Planting Setup
The balance of this section covers items that need to be
completed or checked prior to each field use of the
planter.
1. Read and understand “Important SafetyInformation” on page 1.
2. Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
3. Check that all grease fittings are in place and
lubricated. See “Lubrication” on page 120.
4. Check that all safety decals and reflectors are
correctly located and legible. Replace if damaged.
See “Safety Decals” on page 6.

Hitching Tractor to Planter
Crushing Hazard:
Do not stand or place any part of your body 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 park brake before attaching cables and hoses.
Hydraulic Hookup
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. 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. If an accident occurs, seek immediate
medical attention from a physician familiar with this type of
injury.
3-Point Hitch
Refer to Figure 3
7. Connect your tractor 3-point to the planter 3-point
hitch. If using quick hitch be sure planter locks into
hitch securely.
8. Set tractor brakes and/or put tractor in Park.
9. Raise tractor 3-point just enough to relieve pressure
off of the parking stand.
10. Store 3-point stands. There are two methods:
a. Remove lower pins. Swing stand under hitch.
Reinsert pin beneath stand at inner hole.
b. Remove both pins. Invert stand. Re-pin.
Load Sway Hazard:
Adjust 3-point hitch arms and sway blocks to minimize any
side-to-side sway to assure proper tracking in the field, and
safe road travel.

Hydraulic Hose Hookup
Refer to Figure 4
Great Plains hydraulic hoses have color coded handle
grips to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are marked with
the same color.
To distinguish hoses on the same hydraulic circuit, refer
to the symbol molded into the handle grip. Hoses with an
extended-cylinder symbol feed cylinder base ends.
Hoses with a retracted-cylinder symbol feed cylinder rod
ends.
For hydraulic fan and drive motors, connect the hose
under the retracted cylinder symbol to the pressure side
of the motor. Connect the hose under the extended
cylinder symbol to the return side of the motor.
If the tractor has a limited number of remotes capable of
continuous flow, use one for the hydraulic fan. (See
“Specifications and Capacities” on page 137 for tractor
requirements.)

Refer to Figure 8
13. Raise the 3-point hitch slightly.
14. Remove the lower pin holding the parking
7
stand. Swing the parking stand back and up until it
is above the rear hole. Place the holding pin in the
rear hole and allow the parking stand to rest on it.
This is the transport position for the parking stand.
15. Adjust the top link of a 3-point long enough so the
ball swivel does not bottom out when fully raised.
16. Secure hoses using hose post loops (not shown) so
that hoses have ample slack for lifts and turns, but
cannot get caught in tongue lock or ball swivel.
Failure to do so could cause hose to be crushed
requiring hose replacement.

Monitor Setup
Refer to Figure 9
Model 1625AH planters include one of two
DICKEY-john® seed monitors, depending on row count
and fertilizer type:
• IntelliAg® MVT (Mini Virtual Terminal)
• PM400
Either systems monitors the following elements of a
1625AH planter:
• seeds at each row unit seed tube;
• ground speed;
• dry fertilizer at row drop tubes (1625AHD models);
and,
• dry fertilizer hopper level (1625AHD models).
MVT Monitor Setup
See “MVT Console Installation” on page 156.
Refer to the DICKEY-john®IntelliAg® MVT Manual
(11001-1643) for monitor operations, and the MVT Quick
Start Guide (11001-16a) for setup.
PM400 Monitor Setup
See “PM400 Console Installation” on page 156.
Refer to the DICKEY-john® PM400 Console 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® default values 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
122 m (400-foot) speed calibration described in the
DICKEY-john
®
manual. 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.
Marker Setup (Option)
Prior to first use, check and adjust:
•“Dual Marker Speed Adjustment” on page 68.
Prior to first use, and whenever changing row spacings,
set or reset:
•“Marker Extension” on page 161.
Prior to each planting session, check and adjust:
•“Marker Disk Adjustment” on page 68.

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
1. Carefully read “Important Safety Information” on
page 1.
2. Lubricate planter as indicated under “Lubrication”
on page 120.
3. Check all tires for proper inflation. See “TireInflation Chart” on page 145.
4. Check all bolts, pins and fasteners. Torque as shown
in “Torque Values Chart” on page 145.
5. Check planter for worn or damaged parts. Repair or
replace parts before going to the field.
6. Check hydraulic hoses, fittings and cylinders for
leaks. Repair or replace before going to the field.
7. Be sure hydraulic hoses are securely held out of the
ball swivel area at hitch. Failure to do so could cause
hoses to pinch requiring hose replacement.
High Pressure Fluid Hazard:
Check all hydraulic lines and fittings before applying pressure.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Fluid escaping from a very small hole can
be almost invisible. Use paper or cardboard, not body parts,
and wear heavy gloves to check for suspected leaks. If an
accident occurs, seek immediate medical attention from a
physician familiar with this type of injury.
Frame and Wing Lock Overview
The 1625AH planters include six locks for the frame and
wings:
Refer to Figure 10 (which depicts a folding test on an
incomplete planter)
1. Transport lock channels at wing caster cylinders:
These lock channels prevent the frame from fully
lowering during transport and maintenance. They
are installed prior to folding, and removed after
unfolding. See page 27 and 31.
2. Lift cylinder lock channels above frame pivots:
These lock channels are only required during
maintenance. However, if installed, they must be
removed after unfolding. See page 28 and 102.

Refer to Figure 11 and Figure 10 on page 24
3. Wing locks at mid-tongue and inside wing casters:
These prevent the planter from unfolding while in
transport. The tongue (hitch) is raised to allow the
hooks to clear the locks. See page 27 and 30.

Refer to Figure 12
4. Transport hooks behind the wing pivots:
These prevent the planter frame from fully lowering
when folded. The planter frame is raised to allow the
wings to clear the hooks. The hooks are automatic,
and have an indicator wire to make the status visible
from the tractor cab.
Refer to Figure 12
5. Tongue Latch:
This automatic feature couples the tongue to the
hitch when afield, and helps prevents unintended
folding during reverse moves when unfolded.
Unfolding is complete when the large roller bushing
on top of the tongue is engaged by the tongue safety
latch.

Planter Damage Risk:
Do not plant if the tongue latch is not fully down over the
roller. Frame and opener damage is likely if the planter is
operated with the latch open.

Refer to Figure 14 or Figure 15
6. Fold Solenoid Valve:
The fold and marker cylinders share a hydraulic
circuit via a solenoid valve controlled by a switch box
F
mounted in the tractor cab. The physical appearance
of the switch (and the hitch connector) varies with
the type of seed monitor.
When the switch is in the MARKER or center (OFF)
positions, hydraulic flow to the fold cylinders is
blocked. This provides additional protection against
unintended folding during reverse moves when
unfolded.
Set the switch to FOLD only during fold and unfold
operations. When afield and using markers, the
switch is normally set to and left in the MARKER
position.
Unfolding the Planter
The distance between the tractor and the central cart
decreases by about 3 m (10 feet) during unfolding.
Planter, tractor, or both will move during this operation.
Crushing, Pinch-Point and Overhead Hazards:
To prevent serious injury or death:
▲ Unfold only on hard level ground. Allow ample room.
▲ Allow no one on or near the planter during unfolding.
▲ Stay clear of the wing sweep arcs. The sweep arcs of the
wings have numerous pinch and crush points in the
mechanism. Coulters and row openers are sharp.
▲ Allow no one near planter during unfold. The fertilizer cart
usually moves forward during unfolding.
▲ Do not unfold with planter lowered.
▲ Unfold only with markers resting in transport cradles.
▲ Unfold only if hydraulics are bled free of air and fully
charged with hydraulic oil.
