Important Safety Information

Look for Safety Symbol

The SAFETY ALERT SYMBOL indicates there is a potential hazard to personal safety involved and extra safety precaution must be taken. When you see this symbol, be alert and carefully read the message that fol­lows it. In addition to design and configuration of equip­ment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

Be Aware of Signal Words

Signal words designate a degree or level of hazard seri­ousness.
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This signal word is limited to the most extreme situations, typically for machine components that, for functional pur­poses, cannot be guarded.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe prac­tices.

Hydraulic Charge and Bleed

Normally the hydraulic system is fully charged and bled at the factory before shipping. If repairs have been made, substantial amounts of oil drained from the system, or the following procedures do not correct a problem, see “Bleeding Hydraulics” on page 70.

Lift Hydraulics

Bleeding should not be required other than to raise fully and hold lever on for one minute or until all cylinders extend fully. If this does

Cylinder Hydraulics

Bleeding should not be required other than to fold fully and hold lever on for one minute or until all cylinders reach the end of their stroke.
IMPORTANT !
Do not fold or unfold without first raising planter com­pletely.

Leveling Frame Side-to-Side

All frame sections must be level to maintain even plant­ing depth. Before using the planter in the field, follow these steps to make sure the planter is level side-to-side.
Periodic frame-leveling adjustments should not be nec­essary, but if you are having problems with uneven depth, check planter levelness and follow these proce­dures.
Before making any adjustments be sure the lift cylinders are re-phased and operating properly.
Complete the steps under “Hydraulic Charge and Bleed” on page 15, before proceeding.
Note: Level frame in planting conditions. Failure to do so
may result in machinery not producing desired re­sults.
Refer to Figure 8
1. Unfold the planter fully and set down. Put in field position by lowering and pulling forward.
2. When setting hitch, lower lift cylinders completely. Set the 3-point hitch or hydraulic tongue so that the
top of the tongue tube is: 46in above ground for YP12, or 42in above ground for YP16. This is the starting point for adjustments.

measures approximately 26in from ground to frame at the pivots.When planting at other depths, frame height will vary.
Note: Parallel arms should be parallel with ground or up
to 1in lower in back. Adjusting a 3-point hitch to lev­el parallel arms may cause frame to sit higher or lower than 26in.
4. Check parallel arms behind the pivots to ensure that parallel arms are parallel with ground or up to 1in lower in back. If needed, raise or lower the 3-point to adjust parallel arms.
5. Once parallel arms are parallel with ground or up to 1in lower in back and 3-point is set, measure dis­tance from ground to frame at the pivots.
Refer to Figure 10
6. Measure wings at gauge wheel. If not level with cen­ter of frame, adjust eye bolt accordingly.
Note: Eye-bolt adjustments are easier if the planter is first
lowered to the ground to remove some of the force on the cylinder.

Wing Alignment

To check and adjust wing alignment:
1. Unfold planter, see “Unfolding the Planter” on page 22, and place a block ahead of each wing gauge wheel. Pull planter forward against blocks to rock frames back.
Refer to Figure 11
2. Check for proper alignment by running a string line across back of planter toward outer ends of wings. For proper alignment, outside ends of wings (dimen-
sion A) should be 0-to­(dimension B).
3. To adjust wing alignment, shorten or lengthen eye bolts to change the length of the wing pull bar. Adjust
eye bolts in or out until dimension A is 0 to
1
greater than dimension B.
4. Be sure both wings are adjusted equally or the planter will tend to pull sideways behind the tractor.

Seed Box Pins
Note: Bulk hopper frame has two sets of lifting points.
One set is for normal loading and is tubes. The oth­er set is to allow picking it up from the side for plac­ing in storage near a wall.
IMPORTANT !
Never attempt to move a seed hopper while loaded. It exceeds the lifting capacity of front end loaders and most fork lifts. Always fill seed hopper with seed after it has been securely placed back on the air box.
Note: It may be necessary to adjust the seal on top of air
box to get full contact with the bottom of seed box or hoppers. This is a one-time adjustment.
8. Load the hopper with seed. If using a hydraulic auger with the auxiliary hydraulic kit, refer to the instruc­tions following.
9. Open the slide gate.
10. Return the ladder and platform to the closed posi­tion.
IMPORTANT !
Talc lubricant is mandatory for all seeds, especially treated or inoculated seed when using the precision meter. Do not use talc lubricant when using the finger pickup meters. Use graphite lubricant with finger pickup meters. Refer to “Seed Lubricants” on page

Transporting

!
WARNING
Towing the planter at high speeds or with a vehicle that is not heavy enough could lead to loss of vehicle control. Loss of vehicle control could lead to serious road accidents, injury and death. To reduce the hazard, do not exceed 20 mph.
Before transporting the planter, follow and check these items:
• Set the tractor 3-point hitch control for depth control operation. If the 3-point hitch control is set for load control, the auto load control response may automati­cally adjust too high in given circumstances. This will result with the wing locks disengaging on the road.
• Empty seed box. Empty seed box before transporting if at all possible.
• The planter can be transported with a full box of grain, but the added weight will increase stopping distance and decrease maneuverability.
• Transport planter only while in folded position. Refer to “Folding the Planter” on page 20 and make sure cyl­inder lock channels are in place on the gauge wheels.
• Warning lights. Always use warning lights when trans­porting the planter.
• Road rules. Comply with all federal, state, and local safety laws when traveling on public roads.
• Clearance. Remember that the planter is wider than the tractor. Allow safe clearance.
• Transporting with Markers. Always transport markers in the folded position. Make sure second marker sec­tion rests securely on transport carrier.

401-226M 07/09/2009
Great Plains Manufacturing, Inc. Operating Instructions 31

Marker Operation

Before operating markers, make sure they are properly bled as described in “Bleeding Hydraulics” on page 70.
Dual markers are equipped with a sequence valve to control lift sequence. Starting with both markers up, the sequence is:
1. If the planter is equipped with an auxiliary hydraulic system, set the selector valve (found near the sequence valve at the marker base on the left wing) to “Marker”.
2. Activate tractor hydraulic lever; right marker lowers while left marker stays up.
3. Reverse hydraulic lever; right marker raises while left marker stays up.
4. Activate hydraulic lever; left marker lowers while right marker stays up.
5. Reverse hydraulic lever; left marker raises while right marker stays up.
6. Pattern repeats.
Folding speed of dual markers is adjusted with adjust­ment screws on sequence valve body. Because exces­sive folding speed may damage markers, adjust markers to a safe folding speed according to “Marker Adjust- ments” on page 41.
Note: To get both markers in the lowered position at the
same time, activate hydraulic lever to lower one marker. After marker is lowered, move lever to opposite position then quickly reverse lever and hold until other marker is lowered.

Rephasing Lift System

Over a period of normal use the cylinders may get out of phase. This will cause some planter sections to run higher than others. If this is the case, it will be necessary to rephase lift cylinders. NOTE: Lift cylinders can only be re-phased when planter is unfolded.
To rephase cylinders:
1. Raise the implement completely and hold the hydraulic remote lever on for several seconds until all cylinders are fully extended. Do this every 8 to 10 times you raise planter out of ground.
2. When all cylinders are fully extended, momentarily reverse hydraulic remote lever to retract system
1
in
2
to maintain levelness.

Rephasing Fold System

Over a period of normal use, the cylinders may get out of phase. This is evident by wing gauge wheels not running in their fully rotated positions in front of the planter.
Note: Planter must be folded to re-phase fold system.
Refer “Unfolding the Planter” on page 22, for instructions on re-phasing fold system.

Airbox Operation

The function of the airbox is to carry seed to the meter where seed is blown to the row spacings.

Fan Operation

The fan must hook up to the case drain line first, and it must be operated with the return oil line connected to a low back pressure sump return on the tractor. Check with tractor manufacturer for proper connection of oil sump return line. A low back pressure quick disconnect is sup­plied with the planter for ease of connection to the tractor sump return line.
Use tractor remote hydraulic valve flow control to set fan speed. Start with flow on low setting. 8 - 12 gpm is aver­age flow.
Note: Do not apply pressure to the return line or operate
with restricted return line or motor seals will be damaged.
Recommended butterfly valve setting is 0 mended fan speed depends on planter configuration:
°. Recom-
3800 rpm 2007+ planters using 2007+ 82bu or 150bu
hoppers (or older hoppers with the vent line update)
3500 rpm 2006- planters, or any planter using bulk seed
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 meter box. Fans operating at too low a speed do not create enough air flow to push the seed to the meter causing the seed tube to plug. If air system does not operate suit­ably with fan speeds between 3000-4500 rpm, see “Troubleshooting” on page 65, and then “Fan Adjust- ments” on page 44.
When starting empty you must blow seed out to the meters for two to four minutes to fill meters.
Note: Before corn planting for the first time at the start of
each season, add
1
cup graphite to bottom of air-
3
box.
Watch monitor and adjust fan speed by increasing or decreasing hydraulic flow from tractor.
The monitor has a level sensor located below hopper to warn when box is empty. This gives three to four acres of run time before rows start going empty.

Contact Wheel Drive

Refer to Figure 38
You can adjust the down pressure the contact wheel exerts by adjusting the pressure on the spring.
Note: Do not adjust spring so tight that it will bottom out
when raised.
Refer to Figure 39
Before adjusting spring, raise planter and adjust wheel travel to obtain 1

2
Refer to Figure 40
You can adjust the amount of travel for the contact wheel by loosing the jam nuts and lengthening or shortening the threaded rod.
Note: This adjustment controls the timing of the seed
meter drive when raising and lowering the planter. Increasing the gap between the tires causes seed flow to start and stop with the planter at a lower height. Decreasing the gap will cause seed flow to start and stop at a higher position.
Note: Be sure to check for spring bottoming after making
this adjustment.

Checking Singulated Planting Rate

The seed charts are based on cleaned and sized seed. Extreme seed size variations, foreign material and tire pressure will affect the planting rate. Check the seed population rate as described below.
1. Adjust the planting depth to a shallow setting.
2. Plant at the desired planting speed for a short dis-
tance.
3. Using the table below, determine how many rows
need to be counted.
4. Measure a distance, according to the table, for the
row spacing in the planted area.
5. Count the number of seeds, in the appropriate num-
ber of rows, over the distance measured.
6. Multiply the number of seeds counted by 200 if mea-
suring for
1
acre or 1,000 if measuring for
200
1
1000
acre. This is the plant population in seeds per acre.
Example 1: Single Row
If you have a 10in row spacing planter, according to the chart, three rows must be counted. Measure 17ft 5in and count the number of seeds in three rows. If the number is, for example, 180, multiply 180 by 1,000.
180 1 000,× 180 000 SeedsPerAcre(),=
Example 2: Twin Row
If you have a Twin Row 30in spacing planter, according to the chart, both rows of the twin row must be counted. Measure 87ft 1in and count the number of seeds in the parallel row. If the number is, for example, 170, multiply by 200.
170 200× 34 000 SeedsPerAcre(),=
If the planting population is significantly different than desired, make the following checks:
Double check the transmission and range sprocket com­binations. Refer to the seed population chart for the seed being planted.
Check the air pressure in the gauge wheel tire. See “Tire Inflation” on page 118.
See “Troubleshooting” on page 65.

Seed rate charts

Seed rate charts are in the seed rate book. The charts give transmission sprocket combination and drive range sprockets for row spacing used, to achieve the popula­tion desired.

Setting Fertilizer Rate

!
DANGER
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 an accident.
Fertilizer rate is controlled by two factors:
1. Pump rate, and
2. Orifice size at the row unit drop-line points.
Pump rate depends on sprocket setting (and pump drive type).
Consistent system operation also requires a correctly adjust relief valve and a well-maintained strainer ahead of the pump. See “Setting Relief Valve” on page 63 and “Strainer” on page 63.

Hypro Pump

The liquid fertilizer option uses a Hypro medium pres­sure pump. For pump operation and pump maintenance refer to the Hypro manual. The Hypro manual is supplied in the liquid fertilizer option package.
On new and upgraded planters, the pump is driven by a ground contact wheel, and fertilizer rate is independent of seed rate. Fertilizer rate is set by sprockets on the ground drive assembly. See “Ground Drive Pump” on page 44.
Note: Great Plains recommends checking with your local
Agronomist as soil conditions vary. Soil conditions in your area may need lesser or more amounts of fertilizer than represented in these charts. Do not exceed 12 gallons per acre in any case.
Note: Always remove pump drive chain when not in use.
Do not operate planter pump when not applying material.

Fan Adjustments

Recommended fan butterfly valve setting is 0°. Recom­mended fan speed depends on planter configuration:
3800 rpm 2007+ planters using 2007+ 82bu or 150bu
hoppers (or older hoppers with the vent line update)
3500 rpm 2006- planters, or any planter using bulk seed
boxes or unvented hoppers
Adjust the basic fan rate with the tractor hydraulic system 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.

4. See “Unit-Mounted Coulter Adjustments” on page 51. An optional disk coulter cuts remaining trash and begins opening the seed groove. Its work-
ing depth is set by the side gauge wheels mounting hole selection.
5. See “Row-Unit Planting Depth” on page 52. Row­unit double disk openers widen the coulter groove, making a seed bed. They have adjustments for angle and scraper clearance.
6. See “Side Gauge Wheel Adjustments” on page 52. Side gauge wheels are the primary control over seed depth. They have adjustments for depth and angle. An optional scraper also needs periodic adjustment.
7. See “Meter Exchange and Adjustments” on page 54. A seed tube mounted between the disks (not shown) delivers seed to the trench. It is fed by a seed meter which may have adjustments or inter­changeable wheels.
8. See “Seed Firmer Adjustments” on page 61. An optional seed firmer (Keeton shown) minimizes seed bounce and improves soil contact. It may also deliver fertilizer.
9. See “Press Wheels” on page 62. The press wheels close the furrow, gently pressing the soil over the seed to ensure good seed to soil contact for even emergence. They have adjustments for down-pressure, stagger and angles.

Row-Unit Down Pressure
Row-unit springs provide the down pressure necessary for row-unit disks to open a seed trench. 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.
You can adjust down pressure individually for each row­unit. This is useful for penetrating hard soil and planting in tire tracks. For best results always adjust tractor tires so they are not ahead of 30in rows.
Use only enough down pressure to cut the seed trench and maintain proper soil firming over seed. Excessive row-unit down force will lead to premature wear on row­unit components. Excessive down force will also cause uneven seed depth.

6. Lower row unit until lower parallel arm rests on lock­up pin.
7. Shut off Y-tube port for the current row unit.
8. Repeat for all rows needing lock-up.
IMPORTANT !
Do not pin the row unit while it is in the lowered posi­tion. If the pin is inserted below the parallel arm, unit damage will occur when planting begins.

!
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.

Unit-Mount Cleaner Adjustments
Refer to Figure 57 and Figure 58
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.
1
2
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 contact only 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 lift­assist cylinder locks. Also check bolt tightness prior 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 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
whichever hole pair is most in alignment.
5. UMC-RC: Slide the down-stop on the arm :
- back toward the pivot for shallower cleaning, or
- forward toward the tines for deeper cleaning. Tighten the bolts . Each possible hole pairing adjusts the tine height by about
6. Check the new height measurement.

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 Excess speed results in poor spacing performance due
to seed tube bounce. Excess speed may also result in 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 pick-
up meter shipped with new Great Plains planters, which has an integrated adjustment lever for the brush. If you have the previous model meters, ad­justed by screwdriver rather than lever, rely on counting detents to determine the setting. Not all have 9 detents.
Refer to Figure 77
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. 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.

The insert type is molded into the back. Changing inserts requires meter disassembly, and is not further described in this manual.
IMPORTANT !
Be cautious in using seed treatments, additives, and other chemicals when possible. They can cause meter performance problems and premature wear to meter parts. Avoid the use of graphite with the precision meter. If graphite must be used, use Precision™ Plant­ing graphite or Great Plains graphite which is less abra­sive. Generally, seeds coated with Maxi or similar coatings, such as Captan, benefit from graphite. Always store meters in a dry, secure place. Moisture,

Seed Firmer Adjustments

25 Series row units accept one of two optional firmers.
!
CAUTION
Row unit disk blades may be sharp. Use caution when making adjustments. To adjust the Keeton Firmer, lower the planter until the disks of the row units are resting on the ground.
Keeton Seed Firmer Adjustment
The optional Keeton Seed Firmer is an engineered poly­mer shape that slides down the seed trench. It traps seeds as they exit the seed tube and firms them into the bottom of the furrow.
Refer to Figure 79
The Firmer is provided with a preset tension which is rec­ommended for using the first year. The tension screw
1
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 4 loosen the bolts in the mounting bracket and select differ-
ent 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 problems associated with this, you can lock-up the firmers.

Press Wheels

Attached to the rear of each row-unit is one of several press wheel options.
To provide consistent seed firming, the press wheels are free to move downward from their normal operating posi­tion. This system maintains pressing action even if the row-unit arm is lifted when the disks encounter obstruc­tions.
Refer to Figure 81
Press wheels are attached to each row-unit body. The press wheels close the seed trench and gently press soil over seed.
An adjustable spring in the press wheel mechanism cre­ates the down pressure needed to close the seed trench. The amount of force needed will vary with field condi­tions.
To adjust, move adjustment handle.
• For less down pressure, move handle forward toward
planter.
• For more down pressure, move handle back away
from planter.
Note: Increased press wheel spring force may require in-
creased row-unit down force to maintain depth.
Note: The factory setting on the press wheel is staggered
to achieve optimum residue flow.
Refer to Figure 82

!
DANGER
Wear protective gloves when changing screens.
If changing screen sizes, keep in mind the following.
• A smaller mesh (100) will keep very small manifold ori-
fice plates from plugging so often. However, the screen will have to be cleaned more often.
• A larger mesh (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 resulting in a reduced application rate.
• Mesh sizes: (Smallest) 100, 80, 50, 30 (Largest)

Refer to Figure 86
!
DANGER
Wear protective gloves when changing orifice plates.
Refer to Figure 86
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 85 psi.
The minimum pressure is required to even out the flow of fertilizer between rows. To reduce orifice plugging and pump wear, use the largest orifice practical for your fertil­izer application rate.
The best pressure range to maintain is 15-40 psi to ensure optimum distribution while minimizing leakage.

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, and repair.
Always turn off and remove the tractor key before making any adjustments or performing any maintenance.
!
WARNING
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.
!
WARNING
Escaping fluid under pressure can have sufficient pressure to penetrate the skin. Check all hydraulic lines 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 attention from a physi­cian familiar with this type of injury.
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
76.
7. Replace any worn, damaged, or illegible safety labels by obtaining new labels from your Great Plains dealer.

Bleeding Hydraulics

Bleeding Lift Hydraulics

Normally the lift hydraulics are bled at the factory before shipping and bleeding should not be required other than to raise fully and hold lever on for one minute or until all cylinders extend fully.

Bleeding Fold Cylinder Hydraulics

Normally the fold hydraulics are bled at the factory before shipping and bleeding should not be required other than to fold fully and hold lever on for one minute or until all cylinders reach the end of their stroke.
IMPORTANT !
Do not fold or unfold without first raising planter com­pletely.

Bleeding Marker Hydraulics

To fold properly, the marker hydraulics must be free of air. If the markers fold in jerky, uneven motions, follow these steps.
!
WARNING
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 attention from a physician familiar with this type of injury.
!
WARNING
Only trained personnel should work on system hydraulics!
Check that tractor hydraulic reservoir is full.
1. Set the solenoid to marker operation.
2. With both markers lowered into field position, loosen hydraulic-hose fittings at rod and base ends of marker cylinders. If applicable, loosen fittings on back side of sequence valve.
3. With tractor idling, activate tractor hydraulic valve until oil seeps out around a loosened fitting. Tighten that fitting.
4. Reactivate tractor hydraulic valve until oil seeps out around another loosened fitting. Tighten that fitting. Repeat process until all loosened fittings have been bled and tightened.
!
CAUTION
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.
IMPORTANT !
Bleed only at:
JIC (Joint Industry Conference, 37° flare) or NPT (National Pipe Thread, tapered thread) fittings.
Never bleed at:
ORB (O-Ring Boss) or QD (Quick Disconnect) fittings.
IMPORTANT !
JIC fittings do not require high torque. JIC and O-ring fittings do not require sealant. Always use liquid pipe sealant when adding or replacing (NPT) pipe-thread fittings. To avoid cracking hydraulic fittings from over tightening, and to keep tape fragments from clogging filters, do not use plastic sealant tape.

Finger Set Installation Instructions

Installation Steps

Great Plains recommends having the meter service per­formed by a recognized professional repair facility, such as a certified Meter Max representative.
If you choose to service them yourself, follow these pro­cedures when installing the finger sets.
Refer to Figure 92
11. Be sure the belt is oriented as shown in Figure 92.
12. Slide the finger set over the shaft and rotate clock­wise until it sits against the backing plate.
Note: You will hear a click.
13. Firmly press the finger set against the backing plate while tightening the nut.
14. Tighten the nut until contact is made between the nut and the finger set. Turn turn) (a flat is one of the six sides of the nut) after
contact is made. This equals about four inch- pounds of torque on the nut.
15. Place the slotted nut cover on and carefully align the slotted nut cover with the shaft hole. Insert the cotter pin.
16. Rotate the finger set clockwise and make sure the fingers open and close properly. Fingers should be closed at the 8:00 to 2:00 position (exit hole) and open at the 2:00 to 8:00 position.

Annual Maintenance

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.
Precautions
1. Make sure the finger set is properly torqued against the backing plate. Improperly torqued finger sets may disrupt seed singulation.
2. Avoid seed treatments, additives, and other chemi­cals when possible. They can cause meter perfor­mance problems, premature wear to meter parts, and may cause undesired chemical reaction or dete­rioration to the finger sets. Always use Precision Planting or Great Plains graphite when using seed treatments, see “Seed Lubricants” on page 82. Graphite from other sources may cause premature wear.
3. Always pay attention to your seed monitor, pay atten­tion to your operating manual, and monitor the amount of seed you are planting compared to your expectations. Always investigate abnormalities!

25 Series Row-Unit Side Wheels

Figure 94
1. Lift opener side wheel off the ground. Move tire in and out to check for end play. Check for roughness in bearing by rotating wheel. If bearings are rough, inspect and replace if necessary.
2. The side wheels are preset at the factory. However, because of normal wear it may become necessary to make adjustments so the wheel remains close to the
disk. To prevent plugging, loosen clamp bolt and slide arm inward to take up gap between side
wheel and disk blade. If more adjustment is needed, go to step 3.
3. Remove bolt and wheel . Remove shims from the inside of wheel and place them on the out-
side of wheel . Always place removed shims from the inside to the outside. When installed, wheel should turn freely and not hit the arm at the curve. Do not add any more shims than necessary.

Markers

Markers are a standard factory-installed feature on the Yield Pro Planter, but may be optionally deleted, for example, if all planting is done via GPS navigation.
Markers are not trivial to install as a field upgrade. If any possible future planting might require markers, do not delete them from the initial Yield Pro Planter order.
For operations, see: “Marker Operation” on page 31, and “Marker Adjustments” on page 41.

Fertilizer System

The Yield Pro Planter supports an optional fertilizer sys­tem.This system is required if the optional Keeton seed firmers or Vantage I applicators are to be used for fertiliz­ing.
To meet the needs of users who already have tractor or cart-mounted systems, the YP1225/1625 system is sold as four independent subsystems:
• Manifold (low or high rate)
• Tank system for seed cart
• Ground drive and pump
Great Plains recommends ordering the manifold and tank subsystems at time of initial planter purchase, as they are not trivial to field-install.
