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 conÞguration 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 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 pesticide 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.

Use A Safety Chain (Hydraulic Hitch)

▲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 other specified anchor location. Allow only enough slack to permit turning.

▲Replace chain if any links or end fittings are broken, stretched or damaged.

▲Do not use safety chain for towing.

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

Avoid High Pressure Fluids

Escaping ßuid 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.

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.

▲Before adding chemical to the tank, make sure tank is at least half full. Do not pour concentrate into an empty tank.

▲Never leave fill hose attached to the sprayer after filling tank. Chemicals in tank can siphon out of tank and contaminate freshwater source.

▲Immediately and thoroughly flush any area of the body that is contaminated by chemicals.

▲Do not touch plumbing components with mouth or lips.

▲If chemical is swallowed, carefully follow the chemical manufacturer’s recommendations and consult with a doctor.

Keep Riders Off Machinery

Riders obstruct the operatorÕs 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.

▲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.

Use Safety Lights and Devices

Slow-moving tractors and towed implements can create a hazard when driven on public roads. They are difÞcult 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 20 mph

(32 km/h). Some rough terrains require a slower speed. Sudden braking can cause a towed load to swerve and upset.

▲Do not exceed 20 mph (32 km/h). 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 124.

▲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.

▲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.

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.

Hydraulic Hose Hookup

Refer to Figure 3

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.

Current Style Color Coded Hose Handles

Color	Hydraulic Function
Gray	Fold/Marker
Blue	Lift/Tongue
Black	Fan
Yellow	Hydraulic Drive (Option)

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.

The fan motor further requires hookup of a third line, which returns hydraulic ßuid from the fan motor case.

3-Point Hitch

Refer to Figure 5

10.Connect your tractor 3-point to the planter 3-point hitch. If using quick hitch be sure planter locks into hitch securely.

11.Raise tractor 3-point just enough to relieve pressure off of the parking stand.

12.Store 3-point stands 1 . There are two methods:

a.Remove lower pins 2 . 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.

13.Connect hydraulic hoses to tractor remotes. See ÒHydraulic Hose HookupÓ on page 14

Hitching with Hydraulic Tongue (Option)

Refer to Figure 6 (showing bypass valve closed)

1.Move the tractor to near hitching position.

2.Connect the hydraulic hoses for the tongue circuit. This needs to be done before hitching in order to raise and lower the tongue. See ÒHydraulic Hose HookupÓ on page 14. Allow slack for hitch movements. Close the tongue cylinder bypass valve.

3.Make electrical connections for at least the planter monitor circuit (necessary to control planter hydraulic systems). See page 17.

4.Check that hitch local bypass valve 3 is closed.

Refer to Figure 7

5.Set the cab CFM (Clutch Folding Module) Lift/Hitch switch 2 to Hitch.

6.Retract the Hitch/Lift circuit to set the tongue height to clear the draw-bar. Back the tractor into alignment and pin the draw-bar.

Local Float on Hydraulic Tongue

Refer to Figure 6

The hydraulic tongue must be in Float during planter moves.

If it is necessary to move the planter without Þrst connecting it to a tractor that has a ßoat-capable circuit for the hydraulic tongue, open the bypass valve 3 on the tongue cylinder. This provides local ßoating capability at the tongue.

Raising/Lowering Tongue

In addition to hitching, tongue raising and lowering is required during fold and unfold to engage and disengage the wing locks.

With the standard 3-point hitch, the planter tongue is raised and lowered by raising and lowering the 3-point.

With the optional hydraulic tongue, the planter tongue is raised by extending the hitch cylinder, and lowered by retracting the hitch cylinder.

Hitching with Either Hitch

7.Set the initial tongue height, using 3 point or cylinder of hydraulic tongue. Distance h , measured at top of tongue tube is:

46 inches (117 cm) above ground level for YP12, or 42 inches (107 cm) above ground level for YP16.

Additional planter leveling information is found on page 147.

8.Connect other hydraulic hoses to tractor remotes. See ÒHydraulic Hose HookupÓ on page 14

This will be the transport position for the parking stand.

13.Adjust the top link of a 3-point long enough so the ball swivel does not bottom out when fully raised.

14.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.

15.If equipped with hydraulic hitch option, connect safetychaintoasuitableanchorpointonthetractor.

Lock Up Fertilizer Drive

YP1225A serial number B1059E+

YP1625A serial number B1106F+

Loss of Control and Sharp Object/Crushing Hazards:

Do not lift or lower wheel by spoke or rim; use handle only. Keep legs and feet out from under wheel. 90 pounds (41 kg) force is required to lift wheel. If you lose your grip before pinning, or after unpinning, the arm snaps down rapidly. The traction teeth and the force of the wheel impact can inflict serious injury.

The liquid fertilizer option uses a piston pump driven by a ground contact wheel. When not using the fertilizer drive, preserve the pump by locking up the ground wheel. On older models remove the chain.

Note: Do not operate planter pump when not applying material.

Refer to Figure 11

For YP1225A and YP1625A planters:

16.Remove clevis pin from storage hole 4 .

17.Release the lock arm 5 , lift handle 7 to lift ground wheel up to position it in-between lock arm.

18.Secure with pin clevis 6 and cotter pin.

Operating Instructions

This section covers general operating procedures. Experience, machine familiarity and the following information will lead to efÞcient operation and good working habits. Always operate farm machinery with safety in mind.

Pre-Start Checklist

1.Carefully read ÒImportant Safety InformationÓ on page 1.

2.Lubricate planter as indicated under ÒLubricationÓ on page 104.

3.Check all tires for proper inßation. See ÒTire Inflation ChartÓ on page 127.

4.Check all bolts, pins and fasteners. Torque as shown in ÒEnd of “Appendix A - Reference Information”.Ó on page 140.

5.Check planter for worn or damaged parts. Repair or replace parts before going to the Þeld.

6.Check hydraulic hoses, Þttings and cylinders for leaks. Repair or replace before going to the Þeld.

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.

Wing Lock Overview

Figure 12

29734

Lift Locks and Transport Hook

Refer to Figure 12 and Figure 13
The YP1225A & YP1625A planters include four sets of locks for the frame and wings:
1. Transport hooks behind the wing pivots:
These prevent the planter frame from fully lowering	2
when folded. The planter frame is raised to allow the
wings to clear the hooks. See page 20 and 26.
2. Wing locks at mid-tongue and inside wing casters:	3
These prevent the planter from unfolding while in			3
transport. The tongue (hitch) is raised to allow the
hooks to clear the locks. See page 21 and 26.

3. 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 22 and 26.

4.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 22 and 89.

Unfolding The Planter

The distance between the tractor and the seed structure decreases by about 10 feet (3 m) 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 seed structure 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.

Prepare Hitched Tractor and Planter

1.Move planter to level ground.

2.If tractor movement is not desired, put tractor in Park and/or set parking brakes, or telescoping movement of planter may cause tractor to move backward.

3.On the CFM (Clutch Folding Module), set the following switches to OFF (down):

MASTER switch 1 and Fert.Pump 2 .

Prepare Transport Hooks

Refer to Figure 15

The transport hooks 5 , behind/above wing pivots, prevent the frame from fully lowering when the planter is fully folded. To clear the hooks, the frame is fully raised.

Refer to Figure 14

4.Set CFM Lift/Hitch switch 3 to ÒLiftÓ to enable lift cylinder hydraulics.

5.Set CFM Marker/Fold switch 4 to ÒFoldÓ to enable fold cylinder hydraulics.

6.Activate lift hydraulics. Raise planter until lift hydraulics are fully raised. This raises the wing frames 6 above the hooks 5 .

Planter Damage Risk:

Be sure planter’s lift hydraulics are fully raised before unfolding or frame and/or hook damage WILL occur.

Release Wing Locks

Refer to Figure 17

A pair of inverted hooks 7 on the tongue tube engage locks 8 on each wing when the planter is folded.

Prior to unfolding, this lock system must be released by raising the tongue.

7. This step is slightly different depending on hitch type.

Release Wing Lock with 3-Point Hitch

a.Raise the 3-point hitch to disengage the wing lock. Continue at step 8.

Release Wing Lock with Hydraulic Hitch

Refer to Figure 16

a.Set CFM Lift/Hitch switch 6 to Hitch.

b.Raise hydraulic tongue to disengage wing lock.

Re-Phase Fold Cylinders

8.The fold system uses re-phasing cylinders. It is necessary to re-phase cylinders so wing gauge wheels run in their fully rotated positions in front of planter. To re-phase fold cylinders:

Move and hold lever for Marker/Fold in Fold direction (typically Extend) for 30 seconds. This causes wings to push against the tongue transport hooks 7 .

Partially Unfold

Refer to Figure 17

9.Reverse fold circuit lever until wings clear transport hooks 7 by a few feet.

Lower Tongue

10.Lower 3-point hitch or hydraulic tongue to planting position. See page 17 and page 147 for correct hitch height and depth control settings. If hydraulic tongue, set CFM Lift/Hitch switch 6 to Lift.

Fully Unfold

Refer to Figure 18

11.Unfold the planter fully to planting position. Unfolding is complete when the large roller bushing on top of the tongue is engaged by the tongue safety latch 9 .

Planter Damage Risk:

Failure to lower the tongue before unfolding WILL result in opener or seed delivery system damage. Press wheel assembly components can strike air system components near the air box manifold.

Raising/Lowering Planter

The planter mainframe raises and lowers independently of the tongue.

¥The planter may be fully raised at any time (and must be raised for folding).

¥The planter may be lowered onto its transport lock channels at any time.

¥The planter may be fully lowered, with lock channels removed, only when unfolded.

Refer to Figure 24

The CFM ÒCLUTCHÓ switch positions are not shown because they normally require no attention during lift or lower. Lifting the planter automatically disengages the entire drive system.

The ÒFert.PumpÓ switch 1 has no function on YP1225A & YP1625A planters as shipped by Great Plains because the optional fertilizer system for these planters uses a ground-drive pump that has no electrical control.

Leave or set the CFM Marker/Fold switch 2 in ÒMarkerÓ position to prevent unintended folding.

Raising Planter

The planter may be raised at any time.

1.Set the CFM ÒLift/HitchÓ switch 3 to Lift to enable the lift cylinder circuit.

2.Move the Lift/Hitch circuit lever to extend the lift cylinders.

3.Set the circuit to Neutral to hold the planter at lift. The switch 3 may be left in the ÒLiftÓ position.

4.Install lock channels if raising for transport, parking, storage, adjustments or maintenance.

Lowering Planter

If lock channels are installed, the planter may be lowered at any time. if lock channels are not installed, lower only when unfolded, such as for Þeld turns.

Install lock channels (page 23) as appropriate for next activity.

1.Set the CFM ÒLift/HitchÓ switch 3 to Lift to enable the lift cylinder circuit.

2.Move the Lift/Hitch circuit lever to retract the lift cylinders until settled on lock channels or fully lowered to ground.

3.Set the lift circuit to Neutral for Þeld operation. The switch 3 may be left in the ÒLiftÓ position.

2	1	3

Figure 24

28485

CFM for Lift/Lower

If your planter has an aftermarket pumping system compatible with the IntelliAg¨ system, the ÒFert.PumpÓ switch may require operator attention during lift/lower.

Lowering Planter Hazard:

Use transport locks. A raised planter slowly lowers when held up solely by circuit neutral. Anyone beneath the row units could be trapped and injured. Rely on circuit neutral to hold the planter raised only for brief periods, such as field turns and during lock channel installation. Use lock channels at all other times.

Note: After every few hours of operation (or earlier, if uneven lift is observed), re-phase the lift circuit. At a lift operation, hold the circuit in Extend for 30 seconds.

Crushing Hazard:

Keep all persons away from frame sections during lift and lower. Area under row units is particularly dangerous. Sharp coulter and opener blades descend with hundreds of pounds of down-force.

Note: Unless lock channels are installed, lower the planter only when fully unfolded. Lowering when folded is prevented by the transport locks.

Great Plains Manufacturing, Inc.	Table of Contents Index	Operating Instructions	25

Re-phasing Lift System

Over a period of normal use the cylinders may get out of phase. This will cause some planter sections to run higher than others. If this is the case, it will be necessary to re-phase lift cylinders.

Note: Lift cylinders can only be re-phased when planter is unfolded.

To re-phase cylinders:

1.Raise the implement completely and hold the hydraulic remote lever on for several seconds until all cylinders are fully extended. Do this every 8 to

10 times you raise planter out of ground.

2.When all cylinders are fully extended, momentarily

reverse hydraulic remote lever to retract system 1 2 inch to maintain levelness.

Folding the Planter

The planter must be raised for folding. The tongue is raised and lowered during the sequence.

The distance between the tractor and the seed structure increases by about 10 feet (3 m) during folding. Planter, tractor, or both will move during this operation.

Pinch Point and Crushing Hazard:

To prevent serious injury or death:

▲ Fold only with planter raised and lock channels installed.

▲ Fold only if hydraulics are bled free of air and fully charged with hydraulic oil.

▲Stay away from frame sections when they are being raised or lowered.

▲Keep away and keep others away when folding or unfolding planter.

▲Fold markers onto cradles before folding planter.
