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 limitedto themost 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 5,

thoroughly.

▲ Read all instructions noted on the decals. ▲ Keep decals clean. Replace damaged, faded and illegible

decals.

2014-09-09 Table of Contents Index 401-312M

2 3PYP Table of Contents Index Great Plains Manufacturing, Inc.

Wear Protective Equipment

▲ Wear protective clothing and equipment. ▲ Wear clothing and 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.

Avoid High Pressure Fluids

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

▲ Avoid the hazard byrelieving 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

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.

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.

401-312M Table of Contents Index 2014-09-09

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

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 124.

▲ Do not fold or unfold the planter while the tractoris 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.

Adjust the top link with the tractor turnbuckle and the sliding link .

For ﬁeld operations, adjust the top link so that it is slack with the planter lowered, and taut near the top of hitch travel with the planter raised. The goal is to reduce the weight borne by the rear lift assist cylinders, and reduce any tendency for the tires to dig on end-of-pass turns and during backing.

12. Raise tractor 3-point just enough to relieve pressure from the bases of the parking stands.

Hydraulic Hose Hookup

Only trained personnel should work on system hydraulics!

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.

Refer to Figure 8

Great Plains hydraulic hoses are color coded handle grips to help you hookup hoses to your tractor outlets. Hoses that go to the same remotevalve are markedwith the same color.

To distinguish hoses on the same hydraulic circuit, refer to the symbol molded intothe 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 ﬂuid from the fan motor case.

Frame Height and Leveling

All frame sections must beat the correct height and level to maintain even planting depth.

Periodic frame-leveling adjustments should not be necessary unless the depth control stop has changed since last leveling. If you are having problems with uneven depth, check planter levelness and follow these procedures.

1. Complete the steps under “BleedingHydraulics”on page 100, before proceeding.

2. Before ﬁrst use, and as necessary thereafter, complete or check: “Center Section Leveling” on page 157, “Wing Leveling” on page 157, and “Hydraulic Down Pressure Calibration” on page 159.

3. Unfold the planter fully. See “Unfolding The 3PYP” on page 28.

Note: Older planters with rephasing cylinders need to

have the cylinder rephrased as the ﬁrst step. See page 165.

Note: Level frame in planting conditions.

Failure to do so may result in machinery not producing desired results.

Set Initial Planter Height

The planter is designed to operate with the main tool bar 26 inches (66 cm) above the planting surface (level ground or bed peaks).

Note: Tractor 3-pointcontrol must be in Depth Control

mode, and not Draft Control mode.

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

4. Completely lower the 3-point.

5. Completely lower the Lift Assist. If necessary, ﬁrst raise lift off transport locks, remove and stow locks.

6. Raise the 3-point untilthe toolbar is26 inches above the planting surface.

7. Set the cab 3-point lever stop to capture this “lowered” height.

On beds, it will further be necessary to use customer-supplied blocks to raisethe down-stopposition of the lift assist cylinders. One way to accomplish this is:

Refer to Figure 11

8. Place a carpenter’s level on aside tube of the center frame (pointed to in Figure 11). Have an assistant stand a safe distance away and observe it.

9. With the 3-point lowered to the 26 inch stop, incrementally raise the lift assist until the frame is level.

10. Check that the front tool bar is at 26 inches above planting surface. If not, adjust stop and repeat step 9.

Figure 10

Setting Hitch/Center Height

Figure 11

Raise Parking Stands

Refer to Figure 12

1. If not already atminimum length,remove lower pin of parking stand, fully retract the inner leg , and re-insert pin.

2. Remove upper (holding) pin of parking stand (at bottom of hinge bracket).

Refer to Figure 13

Falling Object Hazard:

Do not stand directly in front of the stand while raising it. You need to have one hand free to insert the pin, and if you lose your grip on the stand, it can swing down and inﬂict injury.

3. Swing the parking stand forward and up until it is above the rear hole. Place the holding pin in the rear-most top hole of the hinge plate. This is the parking stand position for transport and ﬁeld operation.

Note: If 3PYP is equipped with row cleaners, the stand

may not be able toget fullyvertical. It may be necessary to use front top hole .

4. Secure hosesand cables to that theyhave sufﬁcient slack for hitch movements, but cannot get caught between moving parts of planter. Failure to safely route and secure hoses and cables could result in damage requiring component repair/replacement, and lost ﬁeld time.

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

Performthe following steps before transportingthe 3PYP to the ﬁeld.

High Pressure Fluid Hazard:

Escaping ﬂuid under pressure can have sufﬁcient pressure to penetrate the skin. Check all hydrauliclines and ﬁttingsbefore 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 70.

❑ Install seed wheels appropriate for crop. To change

wheels, see “Singulator Plus™ Meter Wheel Replacement” on page 72. Make sure correct 6- or 12-ﬁnger units are installed for the intended row spacing.

❑ Lubricate planter as indicated under “Lubrication”

on page 107.

❑ Check all tires for proper inﬂation. See “Tire

Inﬂation Chart” on page 125.

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

shown in “Torque Values Chart” on page 126.

❑ Check planter for worn or damaged parts. Repair or

replace parts before going to the ﬁeld.

❑ Check hydraulic hoses, ﬁttings, and cylinders for

leaks. Repair or replace before going to the ﬁeld.

Monitor Operation

Refer to Figure 16

The monitor system includes two cab components:

IntelliAg® seed monitor console, and

IntelliAg Switch panel operations are described in this section. Monitor console operation is described in a separate

manual supplied with your 3PYP. Operations covered in that manual (and therefore not in this manual) include:

clutch-folding module (switch panel)

• hydraulic drive control

(option)

• setting rate limits and detecting out-of-limits

• seed rate calibration • GPS integration

• planting rate • fan rpm

• fertilizer rate

Raising/Lowering Planter

Refer to Figure 17 (which depicts theplanter bothraised and unfolded)

Planter raising relies on the3-point hitch in front, andthe Lift Assist cylinders in back. Toraise or lower the planter, move the levers for both the Lift circuit and the 3-point hitch.

Great Plains recommends this sequence (to prevent lateral dragging of wing components):

• in Raising, operate the planter Lift circuit ﬁrst, and

• in Lowering, operate the hitch circuit ﬁrst. The planter may be raisedor lowered in either the folded

or unfolded conﬁguration. The lift assist circuit may also include the optional down

pressure system. This system engages and disengages automatically.

Locking Pins

Refer to Figure 19

Each wing has two removable pins, stored in the parking

stand when not in use:

• Wing Lock Pin Used to connectthe wingtool bar tothe center section

tool barduring planting operations, and keep the wing tool bar at the same height as the mainframe tool bar. When this pin is installed at the coupling, the outer wing is either rigid, or can ﬂex (depending on the planter “ﬂex” conﬁguration)

• Wing Flex Lock Pin

Required to stabilize pivot during folding and unfolding. Used during planting to prevent wing ﬂex.

The following table summarizes pin use.

The INNER pins must be IN and the OUTER pins must be OUT during folding and unfolding, or machine damage will result.

Lift Assist Cylinder Lock-Up

When moving the raised planter more than a short distance, or over any paved surface, do not rely solelyon the lift cylinders to keep it raised. Install transport locks.

Refer to Figure 22

1. Remove the transport locks from their storage positions. Do not store the locking pinson theempty storage tabs.

2. Fully raise the planter (using both 3-point and lift assist).

3. Remove any height adjusting blocks from the lift assist cylinders.

4. Install the transport locks on the cylinder rods , securing them with the same pins used for storage.

5. Lower the lift assist cylinders onto the locks. Leave the 3-point raised.

Figure 22

Transport Lock Storage

25439

Transport the 3PYP to the ﬁeld.

Do so only with wings folded and markers stowed.

1. Disconnect 3-point top link (on 2008+ models with ﬂexible top link).

Loss of Steering Control Hazard:

Never transport with top link connected. When the top link is adjusted for ﬁeld work, some of the weight of the planter mainframe is carried by the top link, which can dangerously reduce tractor front wheel traction and steering control.

2. Make sure tractor is fueled for the work planned.

3. Before departing, ensure that opener depth and seed rate have been determined, or that the necessary data is with you.

4. Close slide gate on hopper or seed box.

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.

5. Hitch, making electrical and hydraulic connections. These steps are described beginning at “Hitching Tractor to Planter” on page 13.

6. If markers are unfolded, fold them per the instructions on page 34. If markers are tilted up, tilt them down intotheir cradles per “Marker Tilt-Down” on page 34.

7. Raise planter.

9. If planter wings are unfolded, fold them. See “Folding the 3PYP” on page 23

10. Always have lights on for highway operation.

11. Comply with all federal, state and local safety laws when traveling on public roads.

12. Travel with caution.

Transport Hazard:

Do not exceed 20 mph, or the posted speed limit (whichever is lower) when driving straight.

Transport Hazard:

Do not exceed 13 mph, or the posted speed limit (whichever is lower) in turns.

13. Keep Clearances in mind. Folded, your 3PYP may be over 25 ft wide and over 121⁄2ft. high.

Steering

Never exceed 13 mph (22 kph) in turns. The 3PYP is extremely heavy, and can cause “over-steer” with most tractors. Above 8 mph the rear wheels caster and provide only modest resistance to side sway by the planter.

If not equipped with Steering, the rear wheels on the 3PYP are full castering at all times.

If your 3PYP is equipped with hydraulic Steering, it is normally engaged at all times when speed is less than 8 mph. Although not used during forward motion in transport, it MUST be engaged for any backing. See “Steering” on page 151

Never exceed 3 mph (5 kph) in reverse.

Machine Damage Risk:

Never back up with the planter lowered.

Machine Damage Risk:

If planter has optional steering, never back up without steering engaged.

Electric Clutch Operation

MASTER

Left

Center

CLUTCH

Figure 27

Cab Selector Controls

Your planter has two or three clutches in the meter drive system. Each clutch enables or disables groups of row units (see table next page). This mode of operation may be needed, for example, for planting a pass that isn’t the full width of the machine.

Which row units are controlled by the clutch switches depends on how your row units are driven.On ground-drive machines, the Left/Right switches control only the wingrow units. Onhydraulic-drive machines, the Left/Right switches each control half the row units (and the Center switch has no function).

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.

Electric Clutch Lock-Up

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

Refer to Figure 28 and Figure 29

1. Remove the three M8-1.25x14 mm metric bolts from their storagelocations nearthe clutch.Savethe nuts.

2. At the clutch, align the cutouts with the holes .

3. Insert the M8-1.25×14 mm metric bolts .

If you observe half the hole obstructed by a metal

disc , you are not at a cutout. If the entire hole is obstructed by ametal disc , 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. Note: Use only the provided 14 mm length bolts. Longer

bolts will damagethe clutch.Shorterbolts may not effect a lock-up. Replacement bolts are Great Plains part number 802-782C.

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.

If your 3PYP has markers, unfolding of the markers is performed only after unfolding the wings.

The Wing switch must be OFF during all marker operations. When Wing Fold is ON, marker switches are disabled.

The tilt operation is performed before the unfold operation. The tiltswitch must beOFF during markerfold operations. When Marker Tilt is ON, the Marker Fold switch is disabled.

Before operating markers, make sure cylinders are properly bled. See “Bleeding Hydraulics” on page 100.

This section presumes correct marker length for your pass spacing. If this has not been set, or needs to be changed, see “Marker Extension” on page 20.

This section presumes a factory marker chain conﬁguration. If your chain has been replaced, or stretched, adjust the linksto thecorrect slacklength. See “Marker Chain Length Adjustment” on page 88

Airbox Operation

Refer to Figure 33

The function of the airbox is tomix seed with turbulent air from the hydraulic fan, which exit through a manifold to the seed tubes which serve the row unit meters.

Fan Operation

The hydraulic fan must hook up to the case drain line ﬁrst. Check with tractor manufacturer for proper connection of oil sump return line.

Use tractor remote hydraulic valve ﬂow control to set fan speed. Start with ﬂow on low setting. 8 to 12 gallons per minute is average ﬂow.

Note: Do not apply pressure to thereturn lineor operate

with restricted return line or motor seals will be damaged.

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

3800 rpm 2008+ planters using 2008+ 82 bu. hoppers

(or older hoppers with the vent line update)

3500 rpm 2006- planters, or any planter using bulkseed

boxes or unvented hoppers

Do not run the fan at speeds over 4500 rpm or speeds under 3000 rpm. Fans operating at too high a speed create too much air ﬂow causing seed to plug up the air box. Fans operating too slowly do not create enough air ﬂow to push theseed tothe meter, causingthe seedtube to plug. 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 56

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.

Before the ﬁrstplanting each season, orwhen using new meters or meter wheels for the ﬁrsttime, for theﬁrst time at the start of each season, add bottom of airbox.

Steering

(APPLIES TO ALL PLANTERS serial numbers A1055S- through A1056S+)

Hydraulic-powered planter steering is standard on 3PYP planters. Before using the system for transport or ﬁeld operations, calibrate the ECU

Steering controls caster position. When the hydraulic steering system is active, the casters steer to match the turning radius of the tractor. This prevents wheel digging in soft soils, and minimizes ﬁeld damage when backing and turning on beds.

Refer to Figure 40

When engaged (via switch ), the system functions automatically, and is active for all forward and reverse movements up to 8.0 mph. Casters ﬂoat during any movement above 8.0 mph (12.9 km/h).

(page 151).

Figure 40

Steering Control Module

29850

Equipment Damage Risk:

All reverseplanter movements requirethe tractor for which the planter steering is calibrated. The casters match steering only with that tractor, and only with steering engaged. See “Emergency Moves Without Steering” on page 154.

Equipment Damage Risk:

If the Power LED is not on and steady, do not move the planter or make only careful forward moves. If the LED is blinking, there is a steering malfunction, and steering is NOT engaged. See “Steering Error Flash Codes” on page 85.

Setting Seed Rate

The procedure for setting seed rate dependson whether the planter has ground (contact) drive or hydraulic drive.

Rate setting details are found in other manuals. Some general information is found in this manual.

Regardless of howrate is set,rate is preciselymeasured by the seed monitor, for most seed types.

Indexing

In twin-row operations with ﬁnger pickup meters, seed-to-seed spacing between pairs of a “row” can be controlled by sprocket indexing (see page 76).

Gauge Wheel Sprocket Selection

On 3PYPs without hydraulic drive, the row units are driven by the gauge wheels, in ground drive.

Refer to Figure 46

The ground drive assembly has three chains that are user adjustable:

1. Range 2 of 6 sprockets, stored on shafts both ends may adjust

2. Transmission 2 of 10 sprockets, stored on vertical spindle both ends may adjust

3. Upper drive 1 of 2 sprockets, selected by spacer only one end adjusts

For a speciﬁc row-spacing, meter and seed, the starting sprocket settings for all three chains are found in the Seed Rate Chart book for this planter (manual part number 401-312B).

Fine adjustment to planting rate is made by the Transmission chain .

Sprocket pairings are identiﬁed in the Charts both by sprocketsize andby which sprocketis mounted onwhich shaft.

Sprockets are sized by tooth count, stamped on the sprocket.The same shaft can be both a driving and driven shaft depending on the required combinations.

The DRIVINGshaft on any chainis the one closer to the gauge wheel (lower in the assembly).

The DRIVEN shaft on any chain is the one further from the gauge wheel (higher in the assembly).

For All Ground Drive Adjustments

Steps:

1. Raise the planter and install lift-assist cylinder locks.

2. Rotate each gauge wheel. Check that seed meters, seed tubes and drives are working properly and are clear of debris and obstructions.

3. Check tire pressure, per “Tire Inﬂation Chart” on page 125.

Drive Range Sprockets

1. Obtain the sprocket pairing from the Seed Rate Chart.

2. Loosen the bolt on the forward idler , and slide the idler to the bottom of its track.

3. Remove the lynch pins from both the driving , and driven shafts.

4. Remove the four alternate sprockets, and set them on the tool bar.

5. Remove the chain and hang it behind a lynch pin on the transmission.

6. Exchange the existing low range sprockets for those called out in the Seed Rate Chart.

The 3PYP must be unfolded,and the tractoror planter parked, before making any of these adjustments.

Equipment Damage/Misapplication Risks:

Any setup and adjustments must be made identically on each of the two gauge wheel drives. If there are any differences, there will be excess clutch wear, and unpredictable seed rate results.

Driven

Equipment Damage/Misapplication Risks:

Make sure the correct sprockets are mounted on the driving or driven shafts as called for by the Charts.

7. Slide the idler up, and tighten its bolt, allowing

⁄4inch slack in the longest chain span.

8. Store the four alternate sprockets on the shafts and re-pin.

Transmission Adjustments

For singulating and ﬁnger pickup meters, rate adjustments should never be necessary. If the seed spacing is not correct, it is likely that there is a planter conﬁguration error or malfunction. Find and correct the problem. Do not attempt to compensate for it by adjusting the target population rate.

For volumetric seeds, after checking initial planting rate, per the Seed Rate manual, it may be necessary to make changes to the transmission sprocket conﬁguration.

If the error is small, a few percent, choose a slightly higher or lower target population from the Seed Rate chart, and install new sprockets for that rate.

If the error is large, it is likely that there is a planter conﬁguration error or malfunction. Find and correct the problem. Do not attempt to compensate for it by adjusting the target population rate.

Gauge Wheel Adjustments

The gauge wheels, which may also be contact drive wheels, serve three functions:

1. Regardless of meter drive type, the gauge wheels each establish the heights of their respective wings. A spring-loaded yoke assembly provides some ﬂexibility over rocks and uneven ground. See “Gauge Wheel Tension” on page 51 to set this spring.

2. In ground-drive (contact-drive), the gauge wheels mutually contribute drive power for the row unit mechanisms. See “Gauge Wheel Sprocket Selection” on page 47.

3. In ground-drive, the gauge wheels control the planting rate at the meters, via three sprocket setup positions. See “Gauge Wheel Sprocket Selection” on page 47.

As the gauge wheeltire wears, this adjustment may need periodic attention.

The planter must be on ﬁrm, level ground for this step (which may be performed when the planter leveling is done). The planter must be unfolded.

1. Raise the planter so that the gauge wheels are just off the ground.

2. Loosen the nut above the yoke block .

Hydraulic Down Pressure

Refer to Figure 53

If the desired opener depth cannot be consistently achieved using spring adjustment (page 62), or the gauge wheel is slippingat theforce required,the optional hydraulic down pressure may remedy the problem. It uses two cylinders to transfer more weight to the wings.

Equipment Damage Risk:

The current hydraulic down pressure option is compatible only with “closed center” tractor hydraulics.

Before making depth adjustments with valve , make sure the system (valve ) has been calibrated. See “Hydraulic Down Pressure Calibration” on page 159.

To adjust hydraulic down pressure:

1. Set the mechanical (cam spring) down pressure to notch 3. See “Row Unit Down Pressure” on page 61.

2. The remote lever must be LOCKED OPEN in this position to provide constant pressure/ﬂow to the openers.

3. With the tractor hydraulic lever locked forward, release the lock disk , turn the knob on the pressure control valve .

4. Watch the pressure gauge and set the desired pressure. Clockwise increases the pressure and counterclockwise decreases pressure.

5. Once the pressure is set, lock the knob with the lock

disk .

Note: Refer to“Hydraulic Down Pressure Calibration”

on page 159 toknow what to expect the planter to do as hydraulics are cycled.

The recommended pressure range for planting is between 400 psi and 600 psi.

The opener pressure setting controls the soil ﬁrming pressure on the press wheel as well as the disk penetrating force. DO NOT use more opener down pressure than necessary to obtain the desired opener penetration and to maintain the proper ﬁrming action over the seed. Excessive opener force will lead to excessive wear and damage of the opener components.

Cart Weight Transfer

On s/n A1025S+ planters, some of the cart weight can be transferred to the mainframe by retraction of the lift-assist cylinders, with a weight-transfer pin in place. This operating mode is compatible with wing-lock, wing-ﬂex and hydraulic down-pressure planters.

1. Disconnect the 3-point top link.

Refer to Figure 54

2. Install the lift-assist weight-transfer pins . The pins are stored in a plate behind the cart parallel arm pivot weldment. Install them in the large holes at the bottom of the rod-endlug inthe frame-to-cart parallel arms.

3. Remove the lift-assist shear bolts from the small

holes below the lift-assist rod-end lug upper pivot pins. Store the bolts in the plates behind the cart parallel arm pivot weldments.

4. Fully retract the lift-assist cylinders when lowering the planter in the ﬁeld.

Priority Flow Hydraulic Systems

On some tractors with load-sensing hydraulics, the tractor remote circuit #1 is capable of taking nearly 100 percent of available hydraulic ﬂow. Operating the openers or markers on circuit #1 will starve the other circuit, making one function inoperable.

To operate markers and constant opener down pressure at the same time, connect the lift assist to circuit #2 and the markers to circuit #3.

Note: On some tractors with very positive remote

hydraulicchecks,aslightincrease inthereading on the pressure gauges may occur after the tractor remote lever isreturned to neutral. This is caused byback pressure on theopener cylindersand may beignored. The NET OPERATINGPRESSUREon the opener cylinders is maintainedat the pressure you selected while the tractor remote lever was held forward–not at the “apparently increased” pressure. Reactivating the tractor lever forward conﬁrms this.

Marker Adjustments

There are ﬁve adjustments for markers:

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

• Marker Width Once set for a speciﬁc row spacing, this only needs periodic checking to ensure the clamp is secure. See page 20.

• Shear Bolt Replacement If a marker hangs up on an obstruction, a bolt at the fold is designed to fail. Positions are provided nearby for storage of replacement shear bolts. See page 88.

• Chain Length Depending on marker width, you may want to adjust the chain length to ensure the markers are off the ground when the planter is raised. See page 88.

• Marker Speed Once initially set by your dealer, this rarely needs modiﬁcation. See page 89.

Crushing and Sharp Object Hazards:

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.

Marker Disk Adjustment

Sharp Object Hazard:

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

Refer to Figure 55

To change angleof cut,and thewidth ofthe mark,loosen

Height Switch Adjustment

Refer to Figure 56

The 3PYP includes a sensing switch that signals the seed monitor (and activates the meter drives), when the planter is lowered for planting.

Although factory-preset for typical planting conditions, Great Plains recommends adjusting this switch for your exact ﬁeld conditions and planting depth. Check the switch seasonally thereafter, or when plantingconditions change. Also perform this adjustment if the switch is replaced or dislodged.

The switch is located on theparallel arms connecting the planter mainframe to the air cart.

Fan Adjustments

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

3800 rpm 2008+ planters using 2008+ 82 bu. hoppers

(or older hoppers with the vent line update)

3500 rpm 2006- planters, or any planter using bulkseed

boxes or unvented hoppers

Adjust the basicfan rate withthe tractorhydraulicsystem and fan rpm display on seed monitor. Do not run the fan over 4500 rpm or under 3000 rpm.

Fans operating at too high a speed create 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 meters, causing the seed tube to plug. 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.

The butterﬂy valve may be helpful if your tractor can maintain a high, but irregular fan rpm. Set the rpm to above 3500 rpm with the valve completely open (0°). Adjust the valve angle in the 20-30° range until you achieve the desired seed ﬂow consistency.

Fertilizer Setup

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.

A fertilizer distribution system is optional on the 3PYP. The Great Plains provisioned components include:

• the lines to the row units (connected to Keeton® seed

ﬁrmers if present),

• oriﬁce ﬁttings for each row

• distribution lines

• manifold

• pressure gauge

• relief valve

• inlet (1 inch female NPT) from pump systemon tractor

(Refer to Figure 60 on page 59)

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

1. Pump drive connection and valves These are separately provisioned tractor-mounted components, and are not described in this manual.

2. Strainer setup This is a separately provisioned tractor-mounted component, but the mesh screen size must be compatible with the oriﬁce plates in the distribution system. See this page and “Fertilizer Oriﬁce Plates” on page 58.

3. Relief valve setting See “Fertilizer Relief Valve” on page 59

4. Pump drive rate This is a separately provisioned tractor-mounted capability. Rate setting is described in this manual, but system operation is not.

5. Row oriﬁce setup See “Fertilizer Oriﬁce Plates” on page 58

Great Plains recommends checking with your local agronomist as soil conditionsvary. Soilconditions inyour area may needless or more fertilizerthan represented in these charts. 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 85 psi. Several system elements affect system pressure, and need initial setup, periodic maintenance, and adjustment when changing seed rates.

Liquid Fertilizer Strainer

A strainer is normally supplied with the fertilizer pump option and is plumbed between the tank(s) and the pump.

The strainer will have been delivered with a mesh screen. You need to check that it is an appropriate size for the oriﬁce plates you plan to use.

The standard oriﬁce plates for the 3PYP are size 48. 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 will starve the pump and will result in a reduced application rate.

Fertilizer Oriﬁce Plates

Refer to Figure 59

To install,insert theplate inside the gasket supplied with the nozzle . Insert the gasketed plate with the legend side facing out the nozzle outlet (typically up).

In general, the oriﬁce needs to be small enough to create enough pressure in the manifold to operate the check valves in the boomclamps, but notso muchthat the system dumps product at the boom relief valve.

The recommend operating pressure is: 15 to 40 psi Using an oriﬁce size too large can result in unequal ﬂow

at rows, intermittent ﬂow, and ﬂow stoppage at rows where pressure fallsbelow the8 psirequired to open the clamp check valve. Using a size too small can cause excess back-pressure resulting in material dumping at the boom relief valve.

Use the same size at all active rows. Exception: If one or two outside “zone coulter”

applicators re-trace the same furrow on opposing passes, you can halve the rate at these rows (only) by using a smaller oriﬁce plate (see table at right)

1 2

Alternate oriﬁce plates are listed under “Fertilizer Oriﬁce Plates” on page 118.

The Seed Rate Chart book for this planter (manual part number 401-312B) contains a table of oriﬁce sizes in gallons per acre.

Fertilizer Row Shut-Off

Refer to Figure 59

Unused drop lines may be shut off by replacing the nozzle with a Great Plains 832-042C cap . Twin row boom systems separately include caps for half the rows.

When installing a cap:

• It is not necessary to remove the gasketedoriﬁce plate

• Use atie wrap orother lineto securethe loose nozzle

• Adjust pump and/or oriﬁce plates for new rate and row

Material Loss Risk:

Do not apply materials without ﬁrst reviewing setup. Shutting off rowsdoes not change the application rate. Unless the pump is reset, it operates at the prior rate, doubling the ﬂow at each nozzle. This can result in excess pressure, and material loss at the relief valve.

Row Unit Down Pressure

Refer to Figure 62

The ideal amount of down-force causes the side gauge wheels to compress any loosesurface soil, butnot press a trench into subsoil.

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

At several row units, inspect the furrow created by the opener discs, but prior to furrow closing by the press wheels.

Note: Be sure to inspect rows both in and out of tire

tracks.

Refer to Figure 63

1. If the side gauge 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 correctand needsno adjustment.

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

Row Unit Shut-Off

Skip-row operations, such as planting from every other row when switching from 30 inch twin-row to 30 inch single-row, requires shutting down unused rows.

Refer to Figure 67 Shutting off seeding at a row involves 4 to 7 steps:

1. Identify the rows to shut off.

2. Disengage row unit drive coupler.

3. Close seed ﬂow to row at Y-tube (if present).

4. Lock up row unit to reduce wear (optional).

5. Reset marker extension (if used).

6. Reset monitor active row pattern and row spacing to avoid nuisance alarms (always done).

7. Shut off fertilizer drop lines (Option, see Seed and Fertilizer Rate manual 401-312B for details).

8. Identify Rows to Shut Off

On twin-row planters, openers are installed with short and long opener mounts. If locking up unused rows of a twin-row planter, shut off the rear (long mount) rows.

On single-row planterswith mid-length mounts, any rows may be locked up.

9. Close Y-Tubes

Refer to Figure 68

If any shut-off rows are served by a Y-tube, close the valvefor the branchto that row. Rotate the valve capuntil the indicator/handle is perpendicular to the tubes.

Closing the Y-tube prevents seed from entering an unused hose, reducing waste and simplifying clean-out.

Raising a row unit on a block by lowering the planter is risky. Full lowering can easily damage components, and hydraulic failure is a safety hazard.

Crushing and Sharp Object Hazards:

Do not attempt to lift the row unit by hand. The weight of the unit, plus the force of the springs (even at minimum) is too great (plus, a free hand is needed for pin insertion). Even with multiple people lifting, hand-lifting is unsafe - there are numerous sharp edges, and the row unit will snap down violently if a grip is lost.

Refer to Figure 70

6. Remove the pin from the storage hole and insert and secure it in the lock-up hole .

7. Lower row unit until lower parallel arm rests on lock-up pin.

8. Shut off Y-tube port for the current row unit.

9. Disengage meter coupler.

10. Repeat for all rows needing lock-up.

Unit-Mount Cleaner Adjustments

Refer to Figure 71 and Figure 72

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 tightnessprior

to each planting session, to avoid down-stop slippage. To adjust the row cleaner:

1. Determine the height adjustment required. Measure from the lowest tine to the ground. Determine the desired new measurement.

2. Support most or all of the weight of the arm to prevent injury and ease the adjustment. Loosen

5 2

bolts on UMC-RC. Remove bent pin on UMRC.

3. Support arm at desired height.

4. UMRC: Slide adjustment tube until cross-tube contacts arm at target height. Insert bent pin in

1 3

whichever hole pair is most in alignment. Each possible hole pairing adjusts thetine height byabout

⁄4inch (19 mm).

5. UMC-RC: Slide the down-stop on the arm :

6 4

- back toward the pivot for shallower cleaning, or

- forward toward the tines for deeper cleaning. Tighten the bolts .

6. Check the new height measurement.

Refer to Row Cleaner manual 204-085M-A for further information on use, adjustment and maintenance of row cleaners.

Sharp Object Hazard:

Row cleaner tines, castingedges and coulterblades are sharp. Wear hand protection when working in this area.

Coulter Adjustments

The ideal operating depth for coulters is1⁄4inch (6 mm) 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 73 and Figure 74

Raise planter andinstall cylinderlocks 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. Becareful around the front end of row units. Row clear tines and coulter blades may be sharp.

To adjust coulter depth:

1. Determine the present opener and coulter depths.

2. Note which bracket hole the coulter is presently using.

3. Determine which new hole will position the coulter closer to the below. If none, don’t move it.

4. Remove the5⁄8-11×4 inch bolt, lock washer and nut ( inFigure 73).

5. Move the blade to the new position. Insert the bolt, and tighten on the lock washer and nut.

Row-Unit Opener Adjustments

25 Series openers have three adjustments:

1. Planting/seed depth.

2. Gauge wheel/opener disk clearance.

3. Opener disk angle.

Setting Planting Depth

Refer to Figure 75

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.

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.

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

• For deeper planting, move the “T” handle back.

Changing plantingdepth may also require changing disk angle.

Disk Angle and Side Depth Wheels

Refer to Figure 76

Disk angle affects seed groove angle/width, and may need to be narrowed to achieve the desired seed depth in some conditions.

Disk-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.

Adjusting Disk Angle & Side Depth Wheels

Refer to Figure 77

For 2 inch planting depth, adjust side depth wheel angle so wheels contact row unit disks at the bottom of wheel. Check with row units in soil so wheels are held up.

At the same time, keep side gauge wheels close to opener disks so openers do not plug with soil or trash.

Note: Wheels should be out far enough so disks and

wheels turn freely.

Refer to Figure 78

To adjust side gauge wheels:

1. Raise planter slightly removing weight from side gauge wheels.

2. Loosen hex-head bolt . Move wheel and arm out

Note: Use this as the starting point foradjustment.

4. Move wheel arm in so side gauge wheel contacts row unit disk. Tighten hex-head bolt to clamp arm

around bushing and shank.

5. Checkwheel-to-disk contact at 2 inch planting depth.

Lift wheel 2 inch and release. When let go, wheel should fall freely.

• If wheel does not contact disk atbottom to area where

blade leaves contact with soil, move hex adjuster until wheel is angled for proper contact with disk.

• If wheel does not fall freely, loosen hex-head bolt

and slide wheelarm outjust until wheel and arm move freely. Retighten hex-head bolt according to grade:

Row-Unit Opener Disk Adjustments

Opener Disc Contact Region

Refer to Figure 79

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 inch (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 79 and Figure 80

1. Raise the planter and install lift cylinder locks.

2. Remove the side gauge wheels 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 thebolt is fully removed from the disk, adust

cap or hold-down bracket will be loose.

4. To reduce thespacing betweenthe discs(the normal 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.

Finger Meter Adjustments

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

⁄2to 5 miles per hour

(7.2-8 km/h). Excess speed causes poor spacing performance due to seed tube bounce, and may also cause improper depth control due to row unit bounce.

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 youhave added pre-existingﬁnger meters after purchase, there is some chance that you may have the previousmodel meter, adjusted by screwdriver ratherthan lever. If so,rely on counting detents to determine the setting. Not all have 9 detents.

Refer to Figure 93

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

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

⁄2. 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), and count detents as you advance it to the desired setting.

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 the row unit itself.

Finger Meter Inserts

Refer to Figure 94

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 inserttype ismolded intothe back. Changing inserts 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,

Figure 94

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 94 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 ﬁngerpickup meterfor Confection seeds is not recommended.

Seed Firmer Adjustments

25 Series row units include a standard seed ﬂap, and accept one of two optional seed ﬁrmers.

Keeton® Seed Firmer Adjustment

The optional Keeton® Seed Firmer is an engineered polymer shape that slides down the seed furrow. It traps seeds as they exit the seed tube and ﬁrms them into the bottom of the “V”.

Refer to Figure 95

The ﬁrmer is provided with a preset tension which is recommended for using the ﬁrst year. The tension screw can be tightened in subsequent years according to your needs. Firmers should provide just enough tension to push seeds to the bottom of the trench.

Measure the distance from the ground to the head of the tension screw. This distance should be 4 to 41⁄2inches If not, loosen the bolts in the mounting bracket and select different holes until the proper measurement is attained.

Seed-Lok® Seed Firmer Lock-Up

Optional Seed-Lok® ﬁrming wheels provide additional seed-to-soil contact. The wheels are spring loaded and do not require adjusting. In some wet and sticky conditions the wheels may accumulate soil. To avoid associated problems, you can lock-up the ﬁrmers.

Sharp Object Hazard:

Row unit disk blades may be sharp. Use caution when making adjustments in this area. To adjust the Keeton® seed ﬁrmer, lower the planter until the disks of the row units are resting on the ground.

Marker Maintenance

Marker Shear Bolt Replacement

Refer to Figure 105

If a marker gets caught or hits an obstruction, it is designed to fail a shear bolt at the fold, pivot on a second bolt , and swing back.

The shear bolt is a hex head cap screw,7⁄16-14×2 inch Grade 5, Great Plains part number 802-589C, plus a

⁄16-14 lock nut, Great Plains part number 803-200C.

Install a replacement shear bolt on the vertical faces on the side opposite from the pivot bolt . Do not use a higher grade bolt, or marker hang-ups may result in machine damage. Do not use a lower grade bolt, or you may experience nuisance shears.

Refer to Figure 106

If your planting frequentlyencounters shear hazards,you can store 6 spare shear bolts/nuts per marker side, in storage holes at the fold point.

Figure 105

Marker Chain Length Adjustment

Great Plains suggests checking marker chain slack every few years. If any maintenance orrepairs causethe chain to be disconnected, correct slack needs to be set on reinstallation.

Perform any checks and adjustments with the marker folded and tilted down into its cradle.

Refer to Figure 107

At the midpoint in the exposed chain, pull it toward the front of the planter.

Measure the distance between that mid-point and the nearest point on either of the two parallel tubes of the marker intermediate arm. The target value is: 18 inches (46 cm).

If theslack is outside this range, remove the bolt and nut at the lower end of the chain and adjust the length.

Dual Marker Speed Adjustment

Crushing and Sharp Object Hazards:

Refer to Figure 108 and Figure 109

Adjust folding speed for dual markers with hex adjustment screws on the sequence valve body. The valvesequence bodyis topleft center section, nearfront. Loosen jam nuts before making adjustments.

There is one adjustment screw for fold-out speed and one for fold-down speed . You can identify adjustment

screws by markings stamped in valve body. Turn adjustment screws clockwise (S: slower) to

decrease folding speed and counterclockwise (F: faster) to increase folding speed.

With tractor idling at a normal operating speed, adjust marker folding to a safe speed. Excessive folding speed could damage markers and void the warranty.

After adjusting thefolding speed, tightenjam nutson hex adjustment screws to hold settings.

Chain Maintenance

Inspect and lubricate chains regularly. The slack of new chains tends to increase during the ﬁrst few hours of operation due to seating.

Chain Slack

Check slack within the ﬁrst 8 hours of operation and tighten idlers as necessary.

Refer to Figure 111, which, for clarity, greatly exaggerates slack, and omitsthe idlers.

1. Measure the span for allowable slack: Locate the longest span of each chain (usually the span which does not run through the idlers).

2. Determine the ideal slack: Long chains (over 36 in./91 cm):

⁄4inch per foot (2.1 cm/m)

Vertical short chains:

⁄4inch per foot (2.1 cm/m)

Horizontal short chains:

⁄2in. per foot (4.2 cm/m).

3. Measure the current slack : Acting at aright angle tothe chain spanat the center of the span, deﬂect the chain in both directions. The slack is the distance of the movement.

4. Adjust the idlers for ideal slack.

Whenever mounting a chain, make sure the clip at the removable link is oriented to minimize snags.

Refer to Figure 112 (gray or stripedarrows show chain direction in chainrouting diagrams)

Install clip with open end facing away from direction of chain travel.

Finger Set Inspection

Finger sets should be inspected on an annual basis. After cleaning, carefully inspect the ﬁngers and springs for wear or other abnormalities that may develop. Excessive wear may disrupt singulation performance.

Great Plains recommends having the meter service performed by a recognized professional repair facility, such as a certiﬁed MeterMax®a representative. If you choose to servicethem yourself, follow these procedures when installing the ﬁnger sets.

See page 70 for meter removal.

Agricultural Chemical Hazard:

Follow material supplier recommendations carefully. Handle the meter as if it were treated seed. use supplier-recommended cleaning agents. Any seed treatment build-up inside a meter is likely to be at a higher concentration than on the actual seed.

Finger Meter Re-Assembly Steps

Refer to Figure 114

1. Be sure the belt is oriented as shown in Figure 114.

2. Slide the ﬁnger set over the shaft and rotate clockwise until it sits against the backing plate .

plate while tightening the nut .

5. Tighten the nut until contact is made between the nut and the ﬁnger set . Turn1⁄4to1⁄2 ﬂat (1⁄24to1⁄12 of a turn) (a ﬂat is one of the six sides of the nut) after contact is made. See page 96 for details. This equals about 0.45 N-m (4 inch-pounds) of torque on the nut.

6. Place the slotted nut cover on and carefully align the slotted nut cover with the shaft hole. Insert the cotter pin .

7. Rotate the ﬁnger set clockwise and make sure the ﬁngers open and close properly. Rotate the meter and make sure the meter turns freely and that there is no air gap between the outer rim of the ashtray and the backing plate. Fingers should be closed at the 8:00 to 2:00 position (exit hole) and open at the 2:00 to 8:00 position.

Precautions

Visually check that thereis novisible airgap between the holder and backing plate.

Make sure the ﬁnger set is properly torqued against the backing plate. Improperly torquedﬁnger setsmay disrupt seed singulation.
