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 resultin death or serious injury. This signal word is limitedtothe 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.

000 112 911 999

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.

2 YP4010HD/YP4025/F Table of Contents Index Great Plains Manufacturing, Inc.

Wear Protective Equipment

▲ Wear protective clothing and equipment. ▲ Wear clothingand equipment appropriate for the job. Avoid

loose-ﬁtting clothing.

▲ Because prolonged exposure to loud noise can cause

hearing impairment or hearing loss, wear suitable hearing protection such as earmuffs or earplugs.

▲ Because operating equipment safely requires your full

attention, avoid wearing entertainment headphones while operating machinery.

Handle Chemicals Properly

Agricultural chemicals can be dangerous. Improper use can seriously injure persons, animals, plants, soil and property.

▲ Read and follow chemical manufacturer’s instructions. ▲ Wear protective clothing. ▲ Handle all chemicals with care. ▲ Avoid inhaling smoke from any type of chemical ﬁre. ▲ Store or dispose of unused chemicals as speciﬁed by

chemical manufacturer.

Use A Safety Chain

(Optional hydraulic hitch only. 3-Point has no 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 other speciﬁed

anchor location. Allow only enoughslackin chain to permit turning.

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

stretched or damaged.

▲ Do not use safety chain for towing.

Avoid High Pressure Fluids

Escaping ﬂuid under pressure can penetrate the skin, causing serious injury.

▲ Avoidthe 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

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.

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

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.

Transport Machinery Safely

Maximum transport speed for implement is 20 mph (32 kph), 13 mph (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 20 mph. Never travel at a speed which does

not allow adequate controlof 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 141.

▲ Do not foldor 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.

You may be severely injured or killed by being crushed between the tractor and planter. Do not stand or place any part of your body between planter and moving tractor. Stop tractor engine and set parking brake before attaching cables and hoses.

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can have sufﬁcient pressure to 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 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.

Hitching with 3-Point

Refer to Figure 3

1. If the planter is model YP4010HDP-3215 (“Even Row 15 in.”), check the conﬁguration of the hitch offset at “YP4010HDP-3215 3-Point Hitch” on page 174.

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

3. Raise tractor 3-point enoughto relievepressure from parking stands.

Load Sway Risk:

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.

4. Connect hydraulic hoses to tractor remotes. See “Hydraulic Hose Hookup” on page 19.

5. Connect electrical cables. See “Electrical Hookup” on page 21.

6. Swing up and pin up 3-point stands. See “Storing 3-Point Parking Stands” on page 22.

7. Remove and store main tongue parking stand. See “Store Main Parking Stand” on page 22.

Hitching with Hydraulic Tongue (Option)

Refer to Figure 4

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 “Hydraulic Hose Hookup” on page 19. Allow slack for hitch movements. Close the tongue cylinder bypass valve.

3. Make electrical connections for at least the planter control circuit(necessary to control planter hydraulic systems). See page 21.

4. Check that hitch local bypass valve is closed.

Refer to Figure 5

5. Set the cab Clutch Folding Module Lift/Hitch switch

to Hitch.

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

7. Connect safety chain to a suitable anchor point on the tractor.

10. Extend the Hitch/Lift circuit to raise the hydraulic tongue just enough to relieve pressure from the parking stand.

11. Remove and store main tongue parking stand. See “Store Main Parking Stand” on page 22.

Raising/Lowering Tongue

In addition to hitching, tongue raising and lowering is required during foldand unfold to engageand 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.

Figure 5

Clutch Folding Module (Hitch)

Local Float on Hydraulic Tongue

Refer to Figure 25 on page 31

The hydraulic tongue must be in Float during planter transport.

If it is necessary to move the planter without ﬁrst connecting it to a tractor that has a ﬂoat-capable circuit for the hydraulic tongue,open the bypassvalve on the tongue cylinder. This provides local ﬂoating capability at the tongue.

Checking Planter Height

The planter isdesigned to operate withall sections ofthe main tool barnominally 26 in. (66 cm) above the planting surface. The height of the center section is not routinely adjustable. Set planting depth with row unit adjustments.

When lowering the planter for the ﬁrst time on the planting ground:

1. Completely lower the maintool bar.If necessary, ﬁrst lift off transport locks, remove and stow locks.

2. Set hitch to planting height.

3. Pull forward a few feet or just over a meter.

Height Mis-adjustment Risk:

Planter must be fully lowered to ﬁeld position (with openers into ground) and hitch height must be set before making side-to-side adjustments.

4. Check tool bar height across planter. See page 98 for further detail and adjustment.

Lock Up Fertilizer Drive

YP40 serial number B1072A+

Loss of Control and Sharp Object/Crushing Hazards:

Do not lift or lower wheel by spoke or rim; use handle only. Keep 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 usesa piston pumpdriven by a ground contact wheel.When not using thefertilizer drive, preserve the pump by locking up the ground wheel. On older models remove the chain.

Note: Do notoperate planter pump when not applying

material.

Refer to Figure 14

Pre-Start Checklist

Perform the followingsteps before transporting the YP40 planter to the ﬁeld.

29264

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can have sufﬁcient pressure to penetrate the skin. Check all hydrauliclines and ﬁttings before applying pressure. 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 assistance from a physician familiar with this type of injury.

❑ Carefully read “Important Safety Information” on

page 1.

❑ Install seed rate meters appropriate for crop. To

change meters, see “Seed Meter Setup and Adjustment” on page 81.

❑ Install seed wheels appropriate for crop. To change

wheels, see “10HD, 25P Meter Wheel Replacement” on page 83. With ﬁnger meters, make sure correct 6- or 12-ﬁnger units are installed for the intended row spacing.

❑ Lubricate planter as indicated under “Lubrication”

on page 114.

❑ Check all tires for proper inﬂation. See “Tire

Inﬂation Chart” on page 144.

❑ Check all bolts, pins, and fasteners. Torque as

shown in “Torque Values Chart” on page 168.

Unfolding The YP40 Planter

The distance between the tractor and the seed structure decreases by 12 ft. (3.7 m) during unfolding. Planter, tractor, or both will move during this operation.

Crushing, Pinch-Point and Overhead Hazards:

To prevent serious injury or death:

▲ Fold only on hard level ground. Allow ample room. ▲ If it is desired that the tractornotmove,make suretractoris

in Park and/or has parking brakes set, otherwise the telescoping movement of the planter is likely to result in tractor movement.

▲ Do not allow anyone to be 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. The seed structure usually

moves forward during unfolding.

▲ Do not unfold with planter lowered, or machine damage

will result.

▲ Unfold only with markers resting in transport cradles. ▲ Unfold only if hydraulics are bled free of air and fully

charged with hydraulic oil.

1. Move to level ground.

Refer to Figure 15

2. On the Clutch Folding Module (CFM), set the following switches to OFF (down): MASTER switch in the CLUTCH cluster , and Fert.Pump .

Folding the YP40 Planter

Fold the YP40planter for moves between ﬁeldsand over public roads, and for storage. The distance between the tractor and the seed structure increasesby 12 ft. (3.7 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 on hard level ground. Allow ample room. ▲ If it is desiredthat the tractor not move during folding, make

sure tractor is in Park and/or has parking brakes set, otherwise the telescoping movement of the planter is likely to result in tractor movement.

▲ Do not allow anyone to be on or near the planter during

folding.

▲ 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 behind the planter. The seed structure moves

backward during folding.

▲ Do not fold with planter lowered, or machine damage will

result.

▲ Fold only with markers resting in transport cradles. ▲ Fold only ifhydraulics are bled free of air andfully charged

with hydraulic oil.

Transporting the Planter

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.

The planter can weigh up to 45000 pounds (20400 kg), depending on conﬁguration and seedload. A tank carthitched to the planter (“in train”) adds another 5000 pounds(2268kg) empty. The tractor unit MUST be rated for the load. If the tractor is not rated for at least 45000 pounds, calculate or obtain a scale weight of the planter and cart. Do not tow if planter exceeds the load rating of the vehicle.

Loss of Control Hazard:

A PFC tank cart in train must be EMPTY. A full tank cart weighs nearly 30000 pounds (13608 kg), and, when hitched to the planter, represents an unsafe highway load regardless of the rating of the towing vehicle. If a PFC cart must be transported loaded, tow it separately. Check Bridge Loads: A loaded planter, or a planter with cart in tow, can exceed the load ratings of bridges you must cross.

29284

.eps

100%

Loss of Control Hazard:

The CFM switch must be setto Hitch, and the hydraulic circuit must be in FLOAT during transport. Failure to do this may resultinhydraulicsystemdamage,transport hooks unlatching, and major planter/tractor damage.

The ﬁgures inthe table below represent alimited number of conﬁgurations. The weight of your planter can vary by thousands of pounds, even if it is the same base model, due to installed options and/or aftermarket equipment. If your tractor weight or capability is near its limits, take your empty planter to a scale and get a precise weight.

Typical YP40 Planter Weights

Reduction of Control Risk:

Seed may be loaded prior to travel, but increases stopping distance, increases the need for caution in turns and braking, and increases tire wear.

❑ Plan the route. If towinga cart hitched to theplanter,

plan the route so that no reverse movements will be necessary. Avoid steep hills. Keep Clearances in mind. Folded, your YP40planter may be nearly 15 ft. (4.6 m) wide and 13 ft. (4 m) high.

❑ Hitch.

Make both electrical and hydraulic connections. See “Hitching Tractor to Planter” on page 17.

❑ If markers are unfolded, fold them.

See “Folding the Markers” on page 41.

❑ Raise planter.

See “Raising/Lowering Planter” on page 29

❑ Install lock-up channels on lift cylinders.

See “Lift Cylinder Lock-Up” on page 31.

❑ Disengage caster locks. See page 33. ❑ Fold and latch lower ladder section. See page 45. ❑ If planter wings are unfolded, fold them.

See “Folding the YP40 Planter” on page 32. Make sure wing locks are engaged.

❑ 3-point hitch:

Lower hitch fully to ensure wings remain locked. Hydraulic hitch: Conﬁrm CFM set to Hitch and hitch circuit in Float.

Breaking and Loss of Control Hazard:

Do not exceed 20 mph when driving straight.

Loss of Control Hazard:

Do not exceed 13 mph in turns.

Steering

Never exceed 13 mph (22 kph) in turns. The YP40 planter is extremely heavy, and can cause “over-steer” with most tractors. The rear-most transport wheels and tank cart lead wheel fully caster, and provide no resistance to side sway by the planter or cart.

Never exceed 3 mph (5 kph) in reverse.

Never back up with the planter lowered or with a fertilizer tank hitched to the planter.

❑ Always have lights on for highway operation. ❑ Comply with all federal, state and local safety laws

when traveling on public roads.

❑ Travel with caution.

Caster Locks - Field Operations

For planting in conditions ranging from ﬂat ground to moderate slopes, the caster locks may be left in the ROAD position, allowing the casters to pivot freely, and simplifying fold/unfold operations.

For planting across extreme hillsides, where side drift might occur, lock the casters after unfolding:

1. Move the lock handle from ROAD to FIELD at each caster.

The lock arm will automatically capture and hold the pivot plate detent when the planter next moves.

See page 33 for unlocking steps.

Field Set-Up Checklist

Use the following tables to develop a ﬁnal checklist for your tractor/planter conﬁguration. Additional or fewer steps may be necessary depending on tractor features, planter options and planting accessories.

Marker Unfolding

Electrocution Hazard:

Beware of overhead electrical lines. If the markers contact lines, the tractor, raised planter and any cart can become “hot” with no indication. A person standing on theground and touching equipment can complete the circuit.Serious injury or death is likely. At higher voltages electrocution can occur without direct contact.

If your YP40 planter has markers, unfolding of the markers is performed only after unfolding the wings.

The Marker/Aux valve on the left wing must be set to “Marker”. See “Auxiliary Hydraulics” on page 52.

Before operating markers, make sure cylinders are properly bled. See “Bleeding Hydraulics” on page 96.

This section presumes correct marker length for your pass spacing. If this has not been set, or needs to be changed, see “Set Marker Extension” on page 145.

Dual markers are equipped with an automatic sequence valve that controls which side activates, as well as marker deployment.

Folding speed of dual markers is adjusted via set screws on the sequence valve body. Excessive folding speed may damage markers.See “Dual Marker Speed Adjustment” on page 172.

CFM: Marker Operation

Overhead Hazard:

To prevent serious injury or death, do not allow anyone to stand near or beyond the end of the wings during marker operations. Marker arms are heavy and marker discs may be sharp.

Figure 31

26119

Marker Unfold (one side)

Refer to Figure 32 and Figure 33

1. If the Auxiliary Hydraulic circuit has been used recently, conﬁrm that the manual Marker/Aux valve on the left wing is set to “Marker”.

2. On the DICKEY-john® Clutch Folding Module (CFM), set “Marker/Fold” switch to Marker (up). The LED above the switch illuminates steadily for normal operation.

3. Move tractor hydraulic control (lever or switch) for the marker circuit to Extend. Hold until marker is completely unfolded. Do not leave tractor control in detent.

4. If the marker side operating is not the desired side, let it unfold part way, and move the tractor’s circuit control to “Retract”. Whenthemarker is folded, move the circuit control to Extendto activate the other side.

On the CFM, leave the “Marker/Fold” switch in “Marker” during normal ﬁeld operations.

To alternate which side is marked:

1. Move the tractor’s circuit control to fold marker. Hold until marker is folded.

2. Reverse the tractor’s circuit control. Hold until the new side’s marker is fully unfolded.

3. Return tractor control to neutral.

Folding the Markers

If your planter has markers, they must be folded and secured before folding the wings.

1. Movethe tractor’s circuit control toRetract. Hold until marker is folded.

2. Set circuit control to neutral.

Unusual Marker Operations

Both Sides Unfolded

With both markers in their cradles:

1. Unfold either side, and when completely deployed…

2. Movelever/switch to Retract momentarily, and return to Extend to deploy other side.

Monitor Operation

Monitor operation is described in a separate manual supplied with your YP40 planter.

Operations covered in that manual (and therefore not in this manual) include:

• hydraulic drive control (option)

• seed rate calibration

• planting rate

• fertilizer rate

• ground speed

• setting rate limits and detecting out-of-limits

• GPS integration

• fan rpm

• low hopper alarm

Planting

When all checklist items are complete, a planting pass normally consists of a few simple steps)

1. Lower planter mainframe

2. Extend a marker

3. Drive forward

4. Scan monitors and controls. Check for errors, alerts and out-of-limits events. Check planting rate reports.

5. Raise marker

6. Raise planter mainframe

7. Turn

8. Extend marker as needed for next pass

9. Subsequent Passes resume at step 1.

When reloading seed and fertilizer, check consumption against anticipated use to that point.

Electric Clutch Operation

The YP40 planter has three clutches in the seed meter drive system. A clutch enables or disables groups of row units. The information in the table below is normally preset at the factory for your planter conﬁguration.

The switches Left / Center / Right correspond to the left wing row units, center section row units and right wing row units respectively.

The Master switch controls all row units, regardless of drive type. For all switches, “OFF” (down) removes power from the clutch, disengaging that set of row units. When any switch (plus Master) is ON, the LED for that switch illuminates steadily.

Electric Clutch Lock-Up

In case of electric clutch failure, an electric clutch can be mechanically engaged.

Refer to Figure 37 and Figure 38

1. Remove the rubber plugs from the oil shield

disc to allow access to the lock-up holes. Plugs simply push out away from the clutch side.

2. Align the cutouts with the holes .

3. Insert the M8-1.25×14 mm long metric bolts . If you observe half the hole obstructed by a metal

disc , you are not at a cutout.

3 4

If the entirehole is obstructed by a metaldisc , you are not at a cutout.

When at a cutout, the bolt will screw in with minimal resistance until the bolt head reaches the clutch face.

4. Re-install the plugs so they are not lost.

Note: Use onlythe provided 14 mm length bolts. Longer

bolts will damagetheclutch. Shorter bolts may not effect a lock-up.

Airbox Operation

Refer to Figure 39

The function of the airbox is to mix seedwith turbulent air from the hydraulic fan , which then exits through a manifold (not shown) to the seed tubes which serve the row unit meters.

Fan Operation

All three (3) fan hydraulic lines must be properly connected. “Hydraulic Hose Hookup” on page 19.

Use tractor remote hydraulic valve ﬂow control to set

fan speed. Start with a very low speed and verify that fanimpeller is spinninginthe correct direction(towardair exit port). Airmoves toward the air box in either direction of fan rotation, but reverse spinning airﬂow is too low to operate the air box.

Start withﬂowonlow setting. 8-12 gpm (30-45 liters/min) is average ﬂow.

Recommended butterﬂy valve setting is 0°. Recommended fan speed depends on planter conﬁguration:

3800 rpm 82 bu. hopper

150 bu. hopper 670/1440 liter seed/fertilizer hopper

3500 rpm bulk seed boxes

a. See manual 403-362M for operation with this

hopper.

Do not run the fan at speeds over 4500 rpm or speeds under 3000 pm. A fan speed too high creates too much air ﬂow causing seed to plug up the meter box. Fans operating too slowly do not create enough air ﬂow to push the seed to the meter, causing the seed tube to plug or meters to run empty. If air system does not operate suitably with fan speeds between 3000-4500 rpm, refer to the troubleshooting chart, and then adjust the fan butterﬂy valve. See “Fan Adjustments” on page 61.

Watch monitor and adjust fan speed by increasing or decreasing hydraulic ﬂow from tractor.

When starting empty you must blow seed out to the meters for two to four minutes to ﬁll meters.

The monitor hasa level sensor below the hopperor seed box to warn when seed box is empty. There are three to four acres of seed in the system when the sensor ﬁrst indicates box empty, depending on seeding rate.

Figure 39

Fan and Air Box

Note: Do not apply pressure to the return line oroperate

with restricted return line, ormotor sealswill be damaged.

Note: Before the ﬁrst planting each season, or when

using new meters or meter wheels for the ﬁrst time, or at the start of each season, before ﬁlling with seed, add

⁄

cup (80 ml) graphite to bottom

of airbox.

Loading Materials (YP4025F only)

The YP4025F-1630 or YP4025F-1670 Planter is a dry fertilizer/seeder version of the YP4025. The standard seed-only hopper or bulk-box capability is replaced by a dual-function hopper.

Seed and fertilizer may be loaded manually or via auger. Before ascending the ladder for loading or auger outlet control:

• Check that the walkboard is closed and latched. Although the YP40F walkboard has a side extension, the latching is identical to the standard walkboard.

• Swing down and latch the lower ladder section.

Refer to Figure 43 (depicting the siderailing closed, and rear railing open)

If loading via auger, the sideand rear top railings may be swung down for clearance.

• Shut off hydraulic fan. Both hopper bins are pressurized when the fan is running.

Auxiliary Hydraulics

Refer to Figure 52, Figure 53 and Figure 54

The YP40 planter includes, as standard equipment, an auxiliary hydraulic circuit, intended to power a seed auger for loading bulk hoppers.

The Aux quick-disconnect ports are onthe frame. This circuit is shared with the markers (if installed).

Note: If markers arenot installed,the Aux/Marker circuit

is always in Aux mode.

Operating Auxiliary Hydraulics

The planter needs to be unfolded for convenient access to the manual hydraulic valve.

1. Fold any extended markers and set the tractor lever for the marker/aux circuit to Neutral.

2. If no markers were unfolded, set the Clutch Folding Module Marker/Fold switch to “Marker”.

3. If the machine has markers, at the left wing tool bar, move the lever on the manual valve from Marker (lever pointing forward) to Aux (lever pointing back).

4. Connect the implement requiring hydraulic power.

5. Brieﬂy Extend the tractor lever for the Marker circuit, engage local valve/switchon implement, and conﬁrm proper implement operation (auger rotation in the correct direction).

Trailer Operations

The YP40 planter optionally includes a trailing pintle hitch, intended for use with Great Plains PFC1600 or PFC2000 fertilizer tank carts. Hitching/hook-up and operating instructions are found in the tank cart Operator’s Manual.

Uncontrollable Load Hazard:

DO NOT EVER transport the tank cart while hitched to the planter (in train) over roads if there is any liquid in either tank. Tank(s) must be empty for transport, or the tank must be towed separately.

Loss of Control Hazard:

Do not attempt reverse operations with a PFC tank hitched to the planter. Trailer direction is extremely difﬁcult to control.

The leading gauge wheels, rear-most transport wheels, PFC tank cart lead wheel and SML tank cart trailing wheels fully caster, and provide no resistance to side sway by the planter or cart.

The PFC1600 and PFC2000 tanks include a ground-driven pump with an electric clutch. The clutch circuit is controlled by the “Fert.Pump” switch on the

Clutch Folding Module. Also, as the pump is ground-driven, it automatically starts and stops with planter movement.

Long-Term Storage

Complete Parking steps ﬁrst.

1. Park the YP40 planter indoors if possible, per the steps above. Great Plains recommends parking/storing inthe raised conﬁguration, folded, on the parking stands and with all lift cylinder locks installed.

2. If no hoppersorseed boxes are mounted, capthe air boxes.

3. If empty seed boxes or hoppers are mounted, close the seed gates and the lids.

4. If partially-loaded seed boxes are mounted, close seed gates, and remove seed boxes. If partially loaded hoppers are present, unload seed via clean-out doors onairbox. Store planter onlywithout seed.

5. Open airbox clean-out doors. Clean out residual seed.

6. Close airbox clean-out doors. Using planter fan,blow seed to meters, cleaning out the lines.

7. Open meter clean-outs. Clean out residual seed.

8. Close all clean-out doors and ports. Shut off all Y-tubes.

9. If seed meters are removed, tie or tape a small plastic bag over ends of all seed delivery tubes, to prevent insects from entering or nesting.

10. Apply grease to exposed cylinder rods to prevent rust.

11. Flush fertilizer lines (if present). Flush system with RVanti-freeze if thereis any chanceof freezing prior to next implement use.

12. Empty and clean fertilizer strainers.

13. Lubricate all points listed in Maintenance to prevent rust.

14. Clean planter of mud, dirt, excess oil and grease.

Fertilizer System Clean-Out

Equipment Damage Risk:

Do not leave fertilizer in the hopper for extended periods. Fertilizer is generally corrosive, and will attack expose metal surfaces.

1. When planting is completed, raise the planter, but leave the fan running for 30 seconds to empty the base of the meter, delivery hoses, and applicators.

2. Unless a tarp will be used to collect the remaining fertilizer,move the planter to an area with a ﬂat clear surface. Comply with fertilizer supplier instructions for suitable areas at which to cover fertilizer.

3. Install transport locks on the raised planter. Shut off the tractor. Mount a collection tarp if only a small amount of fertilizer remains.

Refer to Figure 60

4. Open the calibration door (rear door). If the air system is empty, no material may fall.

5. Open the clean-out door (forward door). Expect material toﬂow in signiﬁcant volume untilthe hopper is empty.

6. Turn the ground drive wheel several revolutions to empty the meter ﬂutes.

If a second person is available, open the hopper lid and inspect the meter ﬂutes while turning the wheel.

7. Recover the fertilizer.

8. With the clean-out and calibration doors open, power-wash the fertilizer hopper from above. Rotate the ground drive to expose all meter ﬂutes to the water. Wipe doors, seals and meter ﬂanges.

9. Use a wire to tie the doors partly open during drying and storage. This allows condensationto drain while preventing pest entry. See page 47 for lid operations prior to storage.

Problem Fertilizer Clean-Outs

For normal unloading of residual materials at completion of planting, see “Long-Term Storage” on page 56.

If, however, parking and storage recommendations have not been followed, it is possible to have hard-to-remove material present.

If the material fails to pass through the fertilizer meter clean-out door, take the following steps to remove it. Do not consider entering the hopper until ﬁrst completing these tasks.

Open the clean-out door (page 57). Remove the strainer (page 47) and evaluate the

problem. For small amounts of residual materials, poking with a

long pole may sufﬁce to push it through the clean-out. If poking doesn’t produce satisfactory results, and you

intend to trywash-out, at least poke one holedownto the meter clean-out, so that water can ﬂow out.

For example:

• If the problem is a single moveable large object, such as a dead animal, ﬁshing out from above may be the solution.

• If the problem is congealed materials, scoop out a sample from above and see if the mass dissolves in water.Ifso,and there is asmall amount of thematerial involved, rinsing, or rinsing and pumping the hopper from above may be the solution.

If wash-out is contemplated, start by introducing a small amount of water, and make sure that it appears at the clean-out within 15minutes.If not, youwill just beadding water to the problem. The hopper is not designed tohold water at full capacity. Add no more water, remove meter box instead, and clean out from below.

Marker Adjustments

There are six adjustments for markers,only one of which is routine:

• Disk Angle (covered in this section)

Even if your row spacing rarely changes, you may need to adjust disk angle for soil conditions and planting speed.

• Shear Bolt Replacement (Maintenance, page 98)

If a marker hangs up on an obstruction, a bolt at the fold is designed to fail.

• Marker Cylinder Bleed (Maintenance, page 97)

Once set for a speciﬁc row spacing, this only needs periodic checking to ensure the clamp is secure.

• Marker Extension (Initial Setup, page 145)

Once set for a speciﬁc row spacing, this only needs periodic checking to ensure the clamp is secure.

• Marker Speed (Initial Setup, page 172)

Once initially set by your dealer, this rarely needs modiﬁcation.

Sharp Overhead Object Hazard:

You may be injured if hit by a folding or unfolding marker. Markers may fall quickly and unexpectedly if the hydraulics fail. Never allow anyone near the planter when folding or unfolding the markers.

401-571M Table of Contents Index 2014-09-08

Great Plains Manufacturing, Inc. Table of Contents Index Adjustments 61

Marker Disk Adjustment

Sharp Object Hazard:

Marker disks may be sharp. Use caution when making adjustments in this area.

Refer to Figure 63

1. To change angle of cut, and the width of the mark, loosen

⁄

inch bolts holding the disk assembly.

For a wider mark , increase the angle of the marker with respect to the tube . For a narrower

mark , reduce the angle.

Note: Donot set a marker angle wider than need to make

a useful mark. Excess angleincreases wear onall marker components.

2. Tighten bolts .

Note: The directionof travel tends to drive the disk

angle to Wide. If bolts are not tight enough, or loosen over time,the diskwill slipinto theWide mark conﬁguration.

Fan Adjustments

Refer to Figure 64

There is one butterﬂy valve at the fan outlet: The recommended butterﬂy valve setting is 0°.

Recommended fan speed depends on planter conﬁguration:

3800 rpm 82 bu. hopper

150 bu. hopper 670/1440 liter seed/fertilizer hopper

3500 rpm bulk seed boxes

the fan at speeds over 4500 rpm or speeds under 3000 rpm.

A fan operating at too higha speed creates too much air ﬂow causing seed to plug up the meter box, and meters to run empty. A fan operating too slowly does not create enough air ﬂow to push the seed to the meter, causing meters to run empty. If air system does not operate suitably with fan speeds between 3000-4500 rpm, refer to the troubleshooting chart, and then adjust the fan butterﬂy valve only as needed.

the meter has less seed, check for blockageupstream. If there is no blockage,checkforinsufﬁcient fan airﬂow: low rpm and/or butterﬂy valve at too high an angle.

The butterﬂy valve may be helpful if your tractor can maintain a high, but irregular fan rpm. Set the rpm to above 3800 rpm with valve completely open (0°).

Adjust valve angle in the 20-30° range until you achieve

the desired seed ﬂow consistency. Normally, each seed meter will be full of seed, up to the top of the bypass screen at the base of the inlet neck. If

Liquid Fertilizer Setup

Note: Fordryfertilizeroperations,seemanual403-362M,

which covers thedry fertilizer/seed hopper andair delivery systemoperation.

Liquid fertilizer distribution systemsa are optional on the YP40 planter and are optimized for use with the optional on-board 2x200 gallon tanks and/or the Great Plains PFC1600 or PFC2000 tank carts.

If installed, there are several points of fertilizer setup and/or adjustment:

1. Pump setting dial or sprockets Basic pumping rate is adjusted at pumps.

For the cart-mounted pump and center section ground-drive pump, a dial on the pump sets rate.

Refer to the Seed Rate manual and the tank cart Operator’s manual.

2. Row oriﬁce setup Oriﬁce plate sizes are chosen to assure consistent pressure at all nozzles. Refer to the Seed Rate manual.

3. Relief valve setting See “Fertilizer Relief Valve” on page 64.

4. Inlets Both Type 2 (2-section, single inlet) and Type 3 (3-section,3-inlet) systems havequick-connectinlets and shutoff valves at the back of the planter. See page 23 for hook-up details.

5. Strainer setup The optional ground drive pump includes a strainer. The mesh screen size must be compatible with the oriﬁce plates in the distribution system. Refer to the Seed Rate manual.

Great Plains recommends checking with your local agronomist as soil conditionsvary. Soilconditions in your area may needless or morefertilizer than representedin these charts. In furrow, do not exceed 12 gallons per acre in any case.

The liquid fertilizer system is designed to operate (ideally) between 15 and 40 psi, but in no case more than 65 psi. Several system elements affect system pressure, and need initial setup, periodic maintenance, and adjustment when changing fertilizer rates.

Agricultural Chemical Hazard:

Some chemicals will cause serious burns, lung damage, and death. Avoid contact with skin or eyes. Wear proper protective equipment as required by chemical manufacturer. Avoid prolonged breathing of chemical fumes. Wear respirator as required by chemical manufacturer. Seek medical assistance immediately if accident occurs. Know what to do in case of accident.

Great Plains Manufacturing, Inc. Table of Contents Index Adjustments 63

Ground Drive Pump

Refer to Figure 65

With a Type2fertilizer system, thepump is driven by a ground contact wheel .Fertilizer rate is independent of seed rate. Fertilizer coarse rate is set by a driving sprocket on the ground drive assembly, and ﬁne rate is adjusted at the setting hub (dial) on the pump.

Equipment Damage/Material Loss Risks:

The ground drive contact wheel and chain system will operate whenever the planter is lowered and in motion. If planting without fertilizing, the pump must not be allowed to run dry. Disconnect the chain or remove a sprocket.

Note: When aType 3 fertilizer system is installed, the

pumpismountedatthesource(notontheplanter), usually on a tank cart.

For sprocket and dial settings, refer to the Seed Rate manual.

Liquid Fertilizer Strainer(s)

The optional ground drive fertilizer pump systems include a strainer at the pump. The Type 3 system relies on strainers at the source, usually on a tank cart.

The strainer(s) are delivered with a mesh screen. You need to checkthat each screen is anappropriate size for the oriﬁce plates you plan to use.

If changing screen sizes, keep in mind the following:

• Generally, select a mesh screen the same or slightly smaller than the oriﬁce size.

• A substantially smaller mesh (e.g. 100) will reduce manifold oriﬁce plates plugging so often, but the strainer screen will have to be cleaned more often.

• A much larger mesh (e.g. 50 or 30) will pass more material but should only be considered when using large manifold oriﬁce plates.

• A plugged or partially plugged screen starves the pump and results in a reduced application rate. Monitor the pressuregaugefor a reduction inpressure that indicates a plugged strainer screen.

Fertilizer Relief Valve

Refer to Figure 67

When a “Type 2” fertilizer system is installed, a relief

1 2

valve and pressure gauge are mounted at each ground drive pump. The relief valve protects the manifold, lines and ﬁttings from excessive pressure. Any product that dumps over the relief valve will discharge from the dump line in relative safety.

To set relief valve:

1. Unlock plastic jam nut from relief valve knob.

2. Unscrew knob clockwise (looking down) until it loses contact with internal spring.

3. Screw knob counterclockwise two turns. Start at this setting.

4. Observe manifold gauge and watch for reliefvalve dump line discharge while operating in the ﬁeld.

5. If valve is dumping product and gauge reads under 65 psi, stop tractor and turn knob clockwise

⁄

turn. Continue operating at normal ﬁeld speed.

Repeat this step as needed until no product is discharged from relief valve dump line .

6. If thepressure gaugereads above 65 psi, change to a larger oriﬁce. Go to step 2 and repeat.

Figure 67

Fertilizer Relief Valve

25164

Fertilizer Oriﬁce Plates

Refer to Figure 68

In general, the oriﬁce needs to be small enough to create at least 15 psi of pressure in the manifold but large enough to prevent the manifold pressure from exceeding 65 psi.

The minimum pressureis required toevenout the ﬂow of fertilizer between rows. To reduce oriﬁce plugging and pump wear, use the largest oriﬁce practical for your fertilizer application rate. Alternate oriﬁce plates are listed in the Seed Rate manual.

The best pressure range to maintain is 20-40 psi to ensure optimum distribution while minimizing leakage. Built-in check valves at the row units prevent ﬂow below 15 psi.

The Seed Rate Chart book for this planter (manual part number 401-571B) contains a table of oriﬁce sizes in gallons per acre.

Oriﬁce plates do not set fertilizer rate. Rate is set at the pump.

High Pressure Fluid Hazard:

Wear protective gloves when changing oriﬁce plates.

Equipment Damage Risk:

Be sure to check that the Terra-Tine Row Cleaner tines DO NOT touch the coulter blade or any other attachments. Such contacts will cause excess wear to all parts involved. At least

⁄

in (13mm) clearance is recommended.

1. When the blade is out of the soil, adjust the Terra-Tine lock collar height to set the height of tine ﬁngers ﬂush with the bottom of coulter blade.

2. For side-to-side alignment, rotate the shank mount around the vertical shaft and retighten the square head set screw (set screws not visible in twin-row illustration).

3. If tines are found to be rolling over, rather than moving trash, spring tension can be increased. See the Terra-Tine manual for details.

Using Terra-Tines with Coulters

Refer to Figure 69 and Figure 70

Tines may be set ahead of, behind , and to the

right or left of frame-mounted coulters.

4. Fore-to-aft adjustment is accomplished by adding or removing the extension arm to place the Terra-Tine Row Cleaner to either side of the coulter hub depending on the desired position or clearance between other attachments. Testing has shown better performance behind the hub, but available space may dictate the mounting position.

Opener Depth

10HDP Opener Depth

Seeding depth on 10HDP Series is set by frame-mounted coulter depth (if installed) and row unit depth. Set frame height (page 24) before making row unit depth adjustments.

10HD Series press wheel height is a stop adjustment and not a spring adjustment. It establishes a ﬁxed relationship between opener depth and theclosed-furrow surface at the press wheel

Refer to Figure 75

Set opener seeding depth by adjusting press-wheel height . To adjust, ﬁrst raise openers slightly, then lift and slide T handles on top of openers. Initially adjust all press wheels to the same height. Individual rows running in tire tracks may need to be set deepera.

• For more shallow seeding, slide T handles forward

• For deeper seeding, slide T handles backward

If press wheels are lifting off ground, check front-to-back level, and increase row unit spring down force.

If press wheels are digging into ground, reduce spring down force at the row units.

The “T” handle sets planting depth by limiting the how high the side depth gauge wheels ride relative to the opener disks. The position of the seed tube itself is ﬁxed relative to the disks, and is not adjusted.

With the planter raised, lift both side depth wheels against the stop and measure the depth of exposed opener disk below it. Do not lift just one wheel, as the 25 Series T handle sets the average depth of both wheels.

Alternatively, check the actual furrow depth with openers lowered and pulled forward in ﬁeld conditions.

To adjust seed depth, pull the “T” handle up and back, move it forward or aft, andset it back in adifferent pair of holes in the scale.

• For shallower planting, move the “T” handle forward.

• For deeper planting, move the “T” handle back. Check opener down-pressure and press wheel(s) after

adjusting depth. See “25P Series Down-Pressure” on page 72, and “Press Wheel Adjustment” on page 89.

Row Unit Down Pressure

10HDP Series Down-Pressure

Refer to Figure 77

An adjuster cam sets row unit spring down pressure individually for each row unit. This is useful for penetrating hard soil and planting in tire tracks.

The notes in the left table below are based on a planter without coulters. About 120 pounds (54 kg) of the down-force is the weight of the row unit itself. The additional force is due to the springs lifting against the mass of the planter.

Test, without seeding, in your conditions, to determine optimal down-force settings.

To adjust down pressure, use an adjustable or open-end

⁄

inch (29 mm) wrench.

1. Raise the planter. Although this adjustment can be made with the planter lowered, the springs will be in tension, and will require more effort. The extra force required may also damage tools.

2. Put tractor in Park and shut it off.

3. Position wrench on hex nut weldment.

4. Pull upper spring link back.

The ideal amount ofdown-force causes the presswheels to compress any loose surface soil, but not press a trench into subsoil.

To assess down-force, operate the YP40 planter for a short distance on typical ground (with or without seeding), and stop. Leave the YP40planter lowered (row units in ground).

At several row units, inspect the furrow created by the opener discs and closed by the press wheels.

Note: Be sureto inspectrows both in and out of tire

tracks.

Refer to Figure 79

1. If the press wheels are leaving no tracks, or light tracks, increase down-force.

2. If the wheels are compressing trash and loose soil, and leaving clear tracks right at the top of the subsoil, down-force is probably correctandneeds no adjustment.

3. If the wheels are creating a trench into the subsoil, down-force is too high and needs to be reduced.

Adjusting Row Unit Down Force

The springs allow the row units to ﬂoat down into depressions and up over obstructions.

With Frame-Mounted Coulters With frame-mounted coulters, the seed trench is

primarily opened by the coulters. Row unit springs provide only additional assistance needed to make a furrow “V” shaped and ensure furrow closure by the press wheels.

Often, the rows may be run at the minimum spring setting, other than in tire tracks, which commonly need some adjustment.

If trench depth is not being achieved across all rows, adjust the force and/or depth of the coulters before making row unit spring adjustments.

With Unit-Mounted Coulters (or no coulters) Without frame-mounted coulters, the row unit springs

provide the primary down force for cutting through residue and opening the seed trench.

25P Series Down-Pressure

Refer to Figure 80

Row unit springs provide the primary down pressure necessary for row unit disks to open a seed trench. The weight of the row units themselves contributes about 145 pounds (66 kg) of the total force.

The springs allow the row units to ﬂoat down into depressions and up over obstructions. Springs also provide down force on coulters when using optional row mounted coulters, and provide theprimary down force on row cleaners (optional), seed ﬁrmers (optional) and press wheels.

An adjuster cam sets down pressure individually for each row unit. This isuseful for penetrating hard soiland planting in tire tracks. For best results always adjust tractor tires so they are not ahead of 30 in. or 70 cm rows.

Unit-Mount Cleaner Adjustments

Refer to Figure 90 and Figure 91

Optional Martin row cleaners are unit-mounted, using: UMRC: Unit-Mount Row Cleaner (stand-alone), or UMC-RC: Unit-Mount Coulter RC (on coulter bracket, with or without a coulter disk present).

There are two adjustments:

1. Wheel placement (forward or aft mounting hole, for more or less aggressive cleaning), and

2. Wheel height, adjusted by a stop. Cleaner arms ﬂoat. The stop only sets the lowest position.

In UMRC mount, a pinned cross-tube on the mount adjusts the depth. In UMC-RC (coulter) mount, a sliding down-stop block adjusts how close to the ground the

row cleaners operate. The row cleaner needs to be adjusted for your

conditions, crop changes, and as coulters and openers wear.Ideally, cleaners contactonly the trash, and do not disturb the soil. If allowed to “dig”, row cleaners can reduce seed coverage.

Suggested initial depth is tine tips at ground level. Make the adjustment with the planter raised. Install

lift-assist cylinder locks. Also check bolt tightness prior to each planting session, to avoid down-stop slippage.

in. above opener depth. Although they may have

originally been set to this depth, coulter (and opener) blades wear with time, and may need adjusting.

Adjusting the coulter depth is accomplished by re-mounting the coulter blade in one of the six mounting holes arranged in a staggered pattern in the coulter bracket.

Refer to Figure 92 and Figure 93

Raise YP40 planter and install cylinder locks before working on coulters. Row unit may be fully lowered or locked up. Do not attempt to move blade when the current or new position causes it to contact the ground during the adjustment. Be carefularound the frontend of row units. Coulter blades may be sharp.

Opener Disc Contact Region

Refer to Figure 95

Opener disc angle and stagger is not adjustable, but disc-to-disc spacing is, and may need attention as discs experience normal wear. Spacers will need to be reset when blades are replaced.

The ideal spacing causes the blades to be in contact for about one inch . If you insert two pieces of paper between the blades, they should slide to within zero (touching) to 1.5 in. (3.8 cm) of each other. If zero, the gap between the blades should not be signiﬁcantly greater than the thickness of two sheets of paper.

If the contact region is signiﬁcantly larger or there is a large gap, it needsto be adjustedby moving one ormore spacer washers.

Adjusting Disc Contact

Refer to Figure 95 and Figure 96

1. Raise the planter and install lift cylinder locks.

2. For25P Series, remove the side gaugewheels on the row unit in need of adjustment.

3. Remove the bolt retaining the opener disc on one side. Carefully remove the disc. Do not lose the hub components and spacer washers , . Make note of how many spacer washers are between the disk and the nut bar .

Note: When the bolt is fully removed from the disk, adust

cap will be loose.

4. To reduce thespacing between the discs(thenormal case), move one spacerwasher from theinside to the outside of the disc. Do not discard any spacers. They will be moved to the inside upon eventual replacement of a completely worn out blade.

5. Re-assemble and check disk contact.

Disc-to-wheel angle and clearance ideally has the wheel just touching the disk when the wheel is raised to planting depth (is up against the stop set by the “T” handle. The goal is to have both disks and wheels turn freely, butkeep soil andtrash from getting between them.

These two adjustments interact with each other. Changing one requires at least checking the other.

In addition to changing the disk angle due to changing depth or new ﬁeld conditions, these two settings may need attention over time as the disk and wheels wear from normal use. This adjustment will also need to be made if any opener components are replaced.

Seed Meter Setup and Adjustment

Your YP40 planter was originally supplied with a speciﬁc seed meter type andinternal components optimized for a particular crop. Depending on the meter type and conﬁguration, there may be adjustments available.

On 10HD and 25P Series openers, you can also entirely change the meter as your crop mix changes.

All YP40 models support:

• Great Plains Singulator Plus™ meters 10HD and 25P instructions begin on this page.

The YP4010HD and YP4025 further support:

• Finger pick-up meters (page 85).

The YP40 does not support feeder cups. Use a Singulator Plus™ meter with speciﬁc wheels for volumetric applications.

10HD, 25P Finger Meter Adjustments

Note: Applies onlyto 10HDand 25PSeries openers. The ﬁnger pick-up meter has an adjustable brush, and

alternate inserts are available for the backing plate. The

brush has been pre-set to the optimum setting for most seed sizes. The factory-installed insert is the “A” insert.

Optimum planting speed is 4

⁄

to 5 miles per hour

(7.2-8 kph). Excess speed causes poor spacing performance due to seed tube bounce, and may also

cause improper depth control due to row unit bounce. Always pay attention to your planter monitor. Compare

actual seed usage to your estimates. Fine-tune your planter by thoroughly checking all key

components including: seed tubes, chains, sprockets, tire pressure, seed monitor, double disk openers, gauge wheels, seed ﬁrmer, closing wheels, parallel arms, and

Figure 112

the row unit itself.

Finger Meter Brush Adjustment

The brush reduces or eliminates “doubles” (delivering two seeds per ﬁnger), but if set too aggressively can cause “skips” (delivering no seed on some ﬁngers). As needed, adjust for minimal doubles and skips.

Note: These instructions describe the current ﬁnger

pickup meter shipped with new Great Plains planters, which has anintegrated adjustment lever forthe brush. If you have added pre-existing ﬁnger meters after purchase, there is some chance that you may have the previous model meter, adjusted by screwdriver rather than lever. If so, rely on counting detents to determine the setting. Not all have 9 detents.

Refer to Figure 112

The adjustable brush provides additional ﬂexibility to accommodate a wide range of seed sizes. Use lever to gently rotate the brush into position.

The settings range from 1 to 5 with detents at each half step, for a totalof 9 detents. The factory default setting is

⁄

. Although the numbers are molded into the meter

housing, only “1” and “5” may be visible. To ensure consistency, rotate the lever fully

counter-clockwise (1), andcountdetents as you advance it to the desired setting.

Use the general guidelines in the table below to adjust the brush position to your seed size and shape. The numbers listed correspondto the numbers printed on the outer housing of your meter. If there is a decal on your meter, its units are seed size in pounds per 80,000 seed bag.

Finger Meter Inserts

Refer to Figure 113

The backing plate is equipped with an “A” insert for Corn, and a “C” insert for Sunﬂower. In tests, these inserts providethe best performance in mostseed sizes.

However, there are alternate inserts that can be used. Before changing to a different insert, please consult with a Great Plains service representative for a recommendation.

The insert type is moldedinto the back. Changinginserts requires meter disassembly.

Meter Reliability Risk:

Be cautious in using seed treatments, additives, and other chemicals when possible. They can cause meter performance problems and premature wear. If graphite is used, use Precision Planting® planting graphite or Great Plains graphite, which is less abrasive. Generally, seeds treated with Maxi, Captan, and similar coatings beneﬁt from graphite. Always store meters in a dry, secure place. Moisture,

temperature, nest-building insects and rodents can create problems. Always pay attention to your seed monitor and operating manual. Monitor the amount of seed you are planting compared to expectations. Investigate abnormalities!

Sunﬂower Meter Conﬁgurations

Review the ﬁnger pickup meter conﬁguration, based on the seed size. See chart below. See “Exchanging Finger Sets” on page 107 for component removal and installation instructions.

The standard Sunﬂower conﬁguration is suitable for #4 and #3 seed sizes. Larger seeds may require the Corn meter conﬁguration.Using a ﬁngerpickupmeter for Confection seeds is not recommended.

Multiple rows fail for lack of seed.

Single or multiple hoses plugging just ahead of airbox.

All rows fail. Lack of seed. Add seed.

1, 2, 3, or more outlets fail. Note: Outlets can be

side-by-side or random. Plugging may also move from one outlet to another.

Little or no seed to many rows, with heavily treated seed.

Y tube is bent/angled off feed pipe. Loosen and rotate pipe so the bend is

straight down and Y-tubeis not pointing to

front or rear of air pipe. Excess fan speed. Reduce fan speed. Blockage in air slot in top of airbox. Clear by using a long slim tool and taking

hose off hose outlet or clean-out door.

Note: May be necessary to take top off

airbox to clear debris from slot, or use side access doors.

Bad hose routing between delivery hose and airbox on wing.

Maintenance and Lubrication

Maintenance

Proper servicing and maintenance is the key to long implement life. With careful and systematic inspection, you can avoid costly maintenance, downtime, andrepair.

Alwaysturn off andremovethe tractor key before making any adjustments or performing any maintenance.

Crushing and Overhead Hazards:

You may be severely injured or killed by being crushed under the falling implement. Always have transport locks in place and frame sufﬁciently blocked up when working on implement.

High Pressure Fluid Hazard:

1. After using your planter for several hours, check all bolts to be sure they are tight.

2. Remove excess slack from chains. Clean and use chain lube on all roller chains as needed.

3. Maintain proper air pressure in planter tires.

4. Keep disk scrapers properly adjusted.

5. Clean planter on a regular basis. Regular and thorough cleaning will lengthen equipment life and reduce maintenance and repair.

6. Lubricate areas listed under “Lubrication” on page 114.

7. Replace any worn, damaged, or illegible safety labels by obtaining new labels from your Great Plains dealer.

Bleeding Hydraulics

Machine Damage Risk:

Do not fold or unfold without ﬁrst raising planter completely.

Bleeding Lift Hydraulics

Normally the lift hydraulics are bled at the factory before shipping, and bleeding should notbe required other than to raise fully and hold lever on for one minute or until all cylinders extend fully.

If it is necessary to further bleed lift system, see “Lift

Cylinder Bleeding” on page 96.

Bleeding Fold Cylinder Hydraulics

Normally the fold hydraulics are bled atthefactory before shipping, and bleeding should notbe required other than to fold fully and hold lever on for one minute or until all cylinders reach the end of their stroke.

Erratic gage wheel behavior, such as wandering back and forth in the ﬁeld, or failing to rotate fully into place while folding, are signs that the fold cylinders need to be bled.

If it is necessary to further bleed fold system, see “Fold

Cylinder Bleeding” on page 97. Lift Cylinder Bleeding

Refer to Figure 121

1. Unfold and lower planter.

2. Un-pin rod endsof all liftcylinders. Position cylinders so that rod ends may extend without striking machine parts.

3. Loosen the JIC ﬁttings at the base end of each master lift cylinder.

4. Extend the circuit until ﬂuid appears at the loosened ﬁttings. Set circuit to Neutral and secure ﬁttings.

5. Loosen the JIC ﬁttings at the base end of each slave lift cylinder.

6. Extend the circuit until ﬂuid appears at the loosened ﬁttings. Set circuit to Neutral and secure ﬁttings.

7. Re-pin rod ends.

Over-Torque Leak Risk:

JIC ﬁttings do not require high torque. Excess torque causes leaks. JIC and ORB ﬁtting do not require sealant.

Bleed lines only at:

JIC (Joint Industry Conference, 37° flare) or NPT (National Pipe Thread, tapered thread) ﬁttings.

Never bleed at:

QD (Quick Disconnect) ﬁttings or ORB (O-Ring Boss) ﬁttings, the O-ring is likely to be torn if

any pressure remains in the circuit.
