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 6,
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 fertilizers, chemical pesticides or herbicides to use the following personal safety equipment.
Waterproof, wide-brimmed hat
Waterproof apron.
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 or if being exposed to spray mist.
Cartridge-type respirator approved for treatment dust or
vapors unless label specifies another type of respirator.
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 must be
destroyed according to state and 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.
Avoid the hazard by relieving pressure before disconnecting
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.

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3

Handle Chemicals Properly

Read and follow chemical manufacturer’s 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.
Immediately and thoroughly flush any area of the body that
is contaminated by chemicals.
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.
After working with chemicals, wash hands and face before
eating. Shower when application is completed for the day.
Never wash out the tanks within 100 feet (30m) of any
freshwater source or in a car wash.
Rinse out the tank. Apply rinse water on last field treated.

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

4 1625AH Table of Contents Index Great Plains Manufacturing, Inc.

Transport Machinery Safely

Maximum transport speed for implement is 32 km/h (20 mph). Some rough terrains require a slower speed. Sudden braking can cause a towed load to swerve and upset.
Do not exceed 32 km/h (20 mph). Never travel speeds which
do 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 137.
Do not fold or unfold the planter while the tractor is
moving.

Shutdown and Storage

Lower planter, put tractor in park, turn off engine, and
remove the key.
Block tires with wheel chocks provided.
Secure planter using blocks and supports provided.
Detach and store planter in an area where children
normally do not play.

Tire Safety

Tire changing can be dangerous and should be performed by trained personnel using correct tools and equipment.
When inflating tires, use a clip-on chuck and extension hose
long enough for you to stand to one side–not in front of or over tire assembly. Use a safety cage if available.
When removing and installing wheels, use wheel-handling
equipment adequate for weight involved.

Preparation and Setup

This section helps you prepare your tractor and planter for use. Before using the 1625AH in the field, you must 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 Safety Information” 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.
5. Inflate tires to pressure recommended and tighten wheel bolts as specified. See “Tire Inflation Chart” on page 145.
6. If returning the planter to service from storage, remove any grease used to protect cylinder rods.

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.)

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 “Tire Inflation 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.

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.
