Important Safety Information
Great Plains Mfg., Inc.
Use Safety Lights and Devices
Slow-moving tractors, self-propelled equipment 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. 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 control of steering
and stopping. Reduce speed if towed load is not equipped with brakes.
Comply with state and local laws.Do not tow an implement that,
when fully loaded, weighs more than 1.5 times the weight of tow­ing vehicle.
Fold drill only when tractor and
drill are stopped and the tractor park brake is set.
Use A Safety Chain
Use a safety chain to help con-
trol drawn machinery should it separate from tractor drawbar.
Use a chain with a strength rat-
ing equal to or greater than the gross weight of towed machin­ery.
Attach chain to tractor drawbar
support or other specified anchor location. Allow only enough slack in chain to permit turning.
Replace chain if any links or end
fittings are broken, stretched or damaged.
Do not use safety
chain for towing.
Practice Safe Maintenance
Understand procedure before
doing work. Use proper tools and equipment. Refer to this manual for additional information.
Work in a clean, dry area.Lower implement to ground, put
tractor in park, turn off engine and remove key before performing maintenance.
Allow implement to cool completely.Inspect all parts. Make sure parts
are in good condition and installed properly.
Remove buildup of grease, oil or
debris.
Remove all tools and unused
parts from implement before oper­ation.

Introduction

Introduction
Great Plains Mfg., Inc.
Great Plains welcomes you to its growing family of new product owners. This implement has been designed with care and built by skilled workers using quality materials. Proper setup, maintenance and safe operating practices will help you get years of satisfactory use from your ma­chine.

Description of Unit

The 2S-2600 is a towed seeding implement. This two-sec­tion drill has a working width of 26 feet and folds to a trans­port width of 15 feet. The drill has straight-arm, double­disk openers. The opener disks make a seed bed, and seed tubes mounted between the disks place seed in the furrow. Press wheels following the opener disks close the furrow and gauge opener seeding depth. A T-handle on the opener body is for seeding-depth adjustments. Seed­ing rates are adjustable with the seed-rate-adjustment handle and sprocket box.
The 2S-2600 features active hydraulic down pressure on the opener frames. When used on a tractor with closed­center hydraulics, constant down pressure ensures even opener penetration in uneven ground. Hydraulic down pressure is adjustable at a single point.
The 2S-2600F allows you to drill seed and apply fertilizer in the same field pass. Dividers partition the drill boxes into seed and fertilizer compartments. The openers apply dry fertilizer to the seed trench before the furrow is closed. You also can use both compartments for seed.

Intended Usage

Use this implement to seed production-agriculture crops in conventional-tillage applications.

Section 1 Preparation and Setup

Section 1 Preparation and Setup
This section will help you prepare your tractor and drill for use. You must adjust drill-tongue height to match your tractor-drawbar height, hook up the drill hydraulics to the tractor, and check that the hydraulics have been bled.

Prestart Checklist

1. Read and understand “Important Safety Informa­tion” beginning on page 1.
2. Check that all working parts are moving freely, bolts are tight and cotter pins are spread.
3. Check that all grease fittings are in place and lubricat­ed. Refer to Lubrication,“Maintenance and Lubrica- tion,” page 48.
4. Check that all safety labels and reflectors arecorrectly located and legible. Replace if damaged. Refer to Safety Labels,“Important Safety Information,” page
4.
5. Inflate tires to recommended pressure as listed on Tire Inflation Chart,“Appendix,” page 60. Tighten wheel bolts as specified on Torque Values Chart,“Ap-
pendix,” page 60.

Tractor Hookup

1. Choose a drill-hitch option that is compatible with your tractor drawbar.
The 2S-2600 has three hitch options:
a clevis hitch,
a small-hole, single-strap hitch or
a large-hole, single-strap hitch.
Use the clevis hitch with tractors that have single-tang drawbars.Use the single-strap hitch for tractors with clevis drawbars. Always use a locking-style hitch pin sized to match the holes in the hitch and drawbar.
2. To adjust the drill hitch to match your tractor-drawbar height, mount tongue jack on side of tongue as shown in Figure 1-1. Use jack to raise drill tongue so lowest hitch hole is 18 inches off ground.
You may be severely injured or killed by being crushed between the tractor and drill. Do not stand or place any part of your body between drill and moving tractor. Stop tractor engine and set park brake before installing hitch pin.
This drill can have positive and negative tongue weight, which can work the hitch pin loose during transport. To avoid serious injury or death due to a road accident, always use a clevis hitch or clevis drawbar with a locking-style hitch pin.

Hydraulic Hose Hookup

Great Plains hydraulic hoses are color coded to help you hook up hoses to your tractor outlets. Hoses are color cod­ed as follows.
Color Tie Hydraulic Function
Red Opener Lift
Blue Transport Lift
White Fold
Orange Marker
To distinguish hoses on the same hydraulic circuit, refer to plastic hose holders. See Figure 1-4. Hoses under extend­ed-cylinder symbol feed cylinder base ends. Hoses under retracted-cylinder symbol feed cylinder rod ends.
Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or card­board, NOT BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, see a doctor im­mediately. Any fluid injected into the skin must be surgically re­moved within a few hours or gangrene may result.
IMPORTANT: To run drill on tractors with open-center hydraulics or on tractors with fixed-displacement hy­draulic pumps, you must install a Great Plains kit, part number 194-143A. If you are not familiar with your tractor hydraulics, consult your tractor dealer.

Section 1 Preparation and Setup

Bleeding the Hydraulics

To function properly, the hydraulics must be free of air. If hydraulics have not been bled, they will operate with jerky, uneven motions and could cause wings to drop rapidly during folding or unfolding. If hydraulics were not bled during initial implement setup or if you replace a part in hydraulic system during the life of the drill, com­plete the following procedures.
Raising openers on unfolded, unhitched drill will cause drill tongue to rise suddenly, which could cause serious injury or death. Be certain that drill is hitched securely to your tractor drawbar and the safety chain is securely attached to tractor before raising openers and unfolding drill.
Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or card­board, NOT BODY PARTS, to check forsuspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgical­ly removed within a few hours or gangrene may result.
as needed. System capacity for entire drill is about 4 1/2 gallons.
2. Make sure opener frames are locked up in road posi-
tion. Refer to Opener Lock Up,“Operation Instruc- tions,” page 20.
3. Turn knob on both pressure-control valves (1) com-
pletely counterclockwise, then turn valves clockwise far enough to build up 1000 psi (about three turns).
4. Turn knob on bypass valve (2) completely clockwise
for no oil flow.
5. Loosen hose-end fittings (3) at the locations shown in
Figure 1-5.
NOTE: Do not loosen an O-ring fitting for bleeding. Bleed­ing air from an O-ring fitting will damage the seal.
6. Slowly supply oil to top side of pressure-control valves
until oil begins to appear at a loosened hose fitting. As oil begins to appear at a fitting, tighten that fitting.
7. Slowly supply oil to bottom side of pressure-control
valves until oil begins to appear at remainingloosened hose fitting. As oil begins to appear at the fitting, tight­en fitting. Continue to supply oil to bottom side of pres­sure-control valves until all openers are raised completely.
8. Move opener transport locks to field position and cycle
openers up and down ten times. Each time you lower

4. Completely extend transport-lift cylinders and imme­diately lock cylinders up by flipping up cylinder lock channels on both transport-lift cylinders. Refer to Fig­ure 2-4, page 14.
The hydraulics could fail, causing the openers to fall and crush you. To prevent serious injury or death, always secure cylinder lock channels over extended transport-lift cylinders before working under openers.
5. When cylinder lock channels are in place, loosen rod­end-hose fitting at elbow on left transport-lift cylinder (2). See Figure 1-7.
6. Slowly supply oil to rod end of transport-lift cylinders until oil appears at loosened hose fitting. As oil begins to appear at fitting, tighten that fitting.
7. Extend transport-lift cylinders and remove cylinder lock channels. Completely cycle transport-lift hydrau­lics several times.

Bleeding Marker Hydraulics

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 drill when folding or unfolding markers.
1. Make sure tractor hydraulic reservoir is full.
2. With markers unfolded in field position, crack hydrau­lic-hose fittings at base and rod ends of each marker cylinder.
3. With tractor at idle speed, activate tractor hydraulic valve forward until oil appears at one fitting. When oil begins to seep out around a fitting, tighten that fitting. Reverse the tractor hydraulic valve until oil appears at opposite hose fitting and tighten that fitting.
4. If you have dual markers, activate your tractor hydrau­lic valve forward again until oil seeps out around one fitting on the other marker cylinder and tighten that fit­ting. Reverse tractor hydraulic valve until oil seeps out around remaining hose fitting and tighten it.
5. Fold and unfold markers slowly to work out all air. Use caution when folding and unfolding markers for the first time, checking for pinching and kinking of hoses.

Setting the Bypass Valve

A bypass valve is plumbed into the opener down pressure circuit. See Figure 2-8. Tractors with load-sensing, closed­center hydraulics require this bypass valve to protect the tractor hydraulic system.
19045
Figure 2-8
Bypass Valve
If you are unsure what type of hydraulic system is on your tractor, contact your tractor manufacturer.

Tractors with Open Center Hydraulics

Close bypass valve for no oil flow by turning knob on valve clockwise completely. Always operate the drill with the by­pass valve closed.

Tractors with Pressure Compensating Closed Center Hydraulics (PC Closed)

Close bypass valve for no oil flow by turning knob on valve clockwise completely. Always operate the drill with the by­pass valve closed.

Tractors with Load Sensing Closed Center Hydraulics (LS Closed) Pressure Flow Compensating (PFC) Systems

IMPORTANT: Failure to use the bypass valve on load­sensing tractors may cause major tractor damage.
1. Close bypass valve for no oil flow by turning knob on valve clockwise completely.
2. With tractor at half throttle, adjust flow-control valve on tractor so openers raise and lower at a reasonable speed. Keep tractor at one-half throttle for remaining steps.
4. Adjust pressure-control valves on drill for opener down pressure so gauges are at 1800 psi. See Figure 2-11.
15557
Figure 2-9
Pressure Control Valves
5. While watching gauges on drill, slowly turn knob on bypass valve counterclockwise. Adjust bypass valve just until needles on gauges begin to move down from 1800 psi. Lock bypass valve at this setting. (See also note below.)
6. Adjust pressure-control valves on drill to desired opener down pressure as explained under Opener Down Pressure, beginning on page 33.
NOTE: The higher the bypass pressure, the greater the potential for oil heating and premature tractor damage. At the same time, for proper opener operation the bypass valve must be set at least 300 psi above the opener down­pressure setting when the tractor is at one-half throttle. Therefore, you should set the bypass valve as low as pos­sible while staying at least 300 psi above the opener down pressure setting.
While 1800 psi is a good starting point for setting the by­pass valve, if you consistently operate the drill with low opener down pressure you can set the bypass valve below 1800 psi. If you consistently operate the drill with very high opener down pressure, you may need a bypass-valve set­ting above 1800 psi.
NOTE: The faster openers raise and lower, the greater po­tential for oil heating, premature wear or tractor damage. Keep tractor at one-half throttle for remaining steps.
3. Engage tractor hydraulics and lower openers. Lock hydraulic lever on tractor for continuous operation.

Adjusting the Counter Balance Valve

On the stem of the valve there is a rubber cap that protects the threads of an adjustment stem. This stem is locked in place with a hex nut. To adjust the valve, loosen the nut and turn the stem using an Allen wrench.
Screwing the stem in (clockwise) pushes on a spring which supplements the pilot line’s force on an internal pis­ton. More spring force will let the valve open with a low pi­lot pressure. Less spring force will require higher pilot pressure to open the valve.
Note: With the screw turned in fully, the spring will develop enough force on the piston to unlock the valve, even with no pilot pressure, causing the openers to settle.
Raise and lower the drill several times then hold hydraulic down pressure on the openers to purge air from the sys­tem and to warm the oil. Repeat.
Raise the openers. Observe the openers closely to detect settling. If the openers remain up, no valve adjustment is needed.
If the openers settle, the stem is screwed in too far. Gently back the stem out until it stops, then screw it in one turn. Generally this is a good starting point. Check for settling.
Backing the stem out will lock the valve, screwing it in too far can cause it to unlock.
A small increase in lowering speed can be achieved by screwing the stem in.

Opener Operation

The openers are raised and lowered on their own hydrau­lic circuit. When used with an active hydraulic system, con­stant hydraulic down pressure is placed on openers for even soil penetration across the drill. To operate openers with live hydraulic power, always connect the opener-lift hoses to the circuit designated for hydraulic-motor control.
To achieve proper opener flotation, the opener hydraulic circuit must be powered by an active hydraulic system. An active hydraulic system requires a tractor with closed-cen­ter hydraulics or pressure-flow compensated hydraulics powered by a variable displacement hydraulic pump.
To run drill on tractors with open-center hydraulics or on tractors with fixed-displacement hydraulic pumps, you must install a Great Plains kit, part number 194-143A. Contact your Great Plains dealer for ordering information.
If you are not familiar with your tractor's hydraulics, consult your tractor dealer.
Crushing hazard – You will be seriously injured or killed if you are caught between raising openers and drill frame. Always stop tractor engine, set park bake, and remove key before ad­justing or servicing openers. Keep all bystanders well away during drill operation.
John Deere 8000 Series tractors: Set timer to con­tinuous. Push lever forward until detent clicks.
Case-IH Magnum tractors: Lock lever forward in detent position. You may need to turn up detent pres­sure to its maximum setting. Do not tie hydraulic lever past detent position with a strap. See your tractor dealer for hydraulic-system details.
Other tractors: Lock lever forward in detent position. You may need to turn up detent pressure to maximum or use a mechanical detent holder to hold lever for­ward. See your tractor dealer for proper means of pro­viding constant flow to openers.
2. Set opener down pressure. There is one pressure­control valve for openers on center of drill and one for openers on outside ends of drill. See Figure 2-12. Ini­tially set down pressure at 800 psi, then adjust as field conditions warrant. For more information on adjusting hydraulic down pressure, refer to Opener Down Pres- sure,“Adjustments,” page 33.
Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or card­board, NOT BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, see a doctor im­mediately. Any fluid injected into the skin must be surgically re­moved within a few hours or gangrene may result.

Opener Operation for Active Hydraulic Systems

IMPORTANT: Tractors with load-sensing hydraulics must use the bypass valve to operate the 2S-2600. Fail­ure to use the bypass valve can cause major tractor damage. Before adjusting opener down pressure, set bypass valve as explained under Setting the Bypass Valve, page 16.
1. Lock hydraulic lever forward during field operation for constant hydraulic flow to openers.
John Deere tractors with Sound-Gard ® Body: Use
lever lock clip, John Deere part number R52667, to lock lever forward. See your tractor dealer for clip pur­chase and installation.
John Deere 7000 Series tractors: Rotate valve
detent selector to motor position to lock lever in for­ward position.

3. Set opener seeding depth by adjusting press-wheel height. To adjust, first raise openers slightly, then lift and slide T-handles on top of openers as shown in Fig­ure 2-11. Adjust all press wheels to the same height.
For shallower seeding, slide T-handles toward drill.
For deeper seeding, slide T-handles away from drill.
While seeding, remember:
Raise openers before turning. Never back up or turn
sharply with openers in ground. Doing so will plug open­ers and may damage equipment.
For information on opener adjustments, see Opener

Press Wheel Adjustment

Priority Flow Hydraulic Systems

On some tractors with load-sensing hydraulics, the #1 cir­cuit 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 openers to circuit #2 and the markers to circuit #3.

Opener Operation for Non-Active Hydraulic Systems

IMPORTANT: Tractors with load-sensing hydraulics must use the bypass valve to operate the 2S-2600. Fail­ure to use the bypass valve can cause major tractor damage. Before adjusting opener down pressure, set bypass valve as explained under Setting the Bypass Valve, page 16.
To run drill with open-center hydraulics or fixed-displace­ment hydraulic pumps requires a Great Plains kit, part number 194-143A. After installing the kit, refer to the fol­lowing instructions for opener operation.
1. Lower opener frames by pushing forward on tractor hydraulic lever. Lock lever temporarily in this position while adjusting opener down pressure.
2. With tractor hydraulic lever locked forward, set opener down pressure. There is one pressure-control valve for openers on center of drill and one for openers on outside ends of drill. See Figure 2-8. Initially set down pressure at 800 psi, then adjust as field conditions warrant. For more information on adjusting opener hydraulic down, refer to Opener Down Pressure, “Adjustments,” page 33.
3. After opener down pressure is set, return tractor hy­draulic lever to neutral. This locks in the selected pres­sure, and opener frames will remain fixed in this position.
IMPORTANT: Open-center tractors and tractors with fixed-displacement pumps are not designed to pro­vide a continuous supply of pressurized oil to remote valves. Locking hydraulic lever forward on these trac­tors can cause overheating of hydraulic oil and trac­tor damage. After setting opener down pressure, always return hydraulic lever to neutral.
4. Set opener seeding depth by adjusting press-wheel height. To adjust, first raise openers slightly, then lift and slide T-handles on top of openers as shown in Fig­ure 2-11. Adjust all press wheels to the same height.
For shallower seeding, slide T-handles toward drill.
For deeper seeding, slide T-handles away from drill.
While seeding, remember:
When approaching rough terrain where you need active
hydraulics to maintain even opener penetration, push tractor hydraulic lever forward momentarily. As soon as you return to level ground, return lever to neutral. Do not activate tractor hydraulic lever for more than 20 seconds at a time, once every 2 minutes. Always wait until tractor and drill are on level ground before returning lever to neutral. You can bump tractor hydraulic lever forward any time on level ground to assure the preset pressure is correctly locked in and to reset the system.
Raise openers before turning. Never back up or turn
sharply with openers in ground. Doing so will plug open­ers and may damage equipment.
Each time you lower openers, hold tractor remote hy-
draulic lever forward for a few seconds to recharge cir­cuit, then return lever to neutral. Return lever to neutral only when tractor and drill are on level ground.
For information on opener adjustments, see Opener
Down Pressure and Opener Depth,“Adjustments,”
starting on page 33. For more information on trouble­shooting opener problems, see “Troubleshooting,” page 44.

Fertilizer Box Operation

The 2S-2600F is equipped with a fertilizer compartment so you can plant seed and apply fertilizer in the same field pass. Use only dry, granular fertilizer in the fertilizer box.
1. Clean any seed or debris from fertilizer compartment.
2. Adjust seed and fertilizer compartments to desired ca­pacity. The 2S-2600F is equipped with standard divid­ers that partition drill boxes into 60 percent seed and 40 percent fertilizer. If your drill is outfitted with option­al offset dividers, you can change the seed-to-fertilizer ratio. Refer to Seed and Fertilizer Capacity,“Adjust- ments,” on page 41.
3. Calibrate fertilizer-application rate as explained under Fertilizer Rate Calibration,“Adjustments,” page 29.
4. Check that divider door is closed so seed and fertilizer cannot pass between compartments. See Figure 2-
16.
5. Check that fertilizer cleanout door is latched securely (1) as shown in Figure 2-14. Close all door latches be­fore loading fertilizer compartment.

4. To avoid unnecessary wear, remove fertilizer drive chains.

Shaft Monitor Operation

To operate shaft monitor, turn system on by activating on­off switch on monitor head. If seed-cup shaft is turning, both of the lights will be on and the alarm will not sound.
If either seed-cup shaft stops for 30 seconds, an alarm will sound and a light on the monitor will flash designating the failed shaft.
The 30-second delay is to prevent nuisance alarms when turning at the end of the field. If a failure does occur and an alarm sounds, remember you have traveled for 30 sec­onds without planting.

Marker Operation

Optional markers are equipped with a double-selector valve to combine the transport-fold circuit with the marker circuit.
After drill is unfolded for field operation, shift double-selec­tor valve to marker circuit as shown in Figure 2-18. Before operating markers, make sure they are properly bled as described in Bleeding the Hydraulics, “Drill Preparation and Setup,” page 11.
15550
Figure 2-18
Shifting the Double Selector Valve
To operate a single marker, activate tractor remote hydrau­lic lever to move marker in desired direction.
Single markersare equipped with a needle valve to control marker folding speed. Excessive folding speed can dam­age markers, so adjust needle valve to a safe operating speed as described under Marker Adjustments, “Adjust- ments,” page 21.
Dual markers are equipped with a sequence valve to con­trol lift sequence. Starting with both markers up, the se­quence is:
1. Activate hydraulic lever; right marker lowers while left marker stays up.
2. Reverse hydraulic lever; right marker raises while left marker stays up.
3. Activate hydraulic lever; left marker lowers while right marker stays up.
4. Reverse hydraulic lever; left marker raises while right marker stays up.
5. Pattern repeats.
Folding speed of dual markers is adjusted with adjustment screws on sequence-valve body. Excessive folding speed can damage markers, so adjust markers to a safe folding speed as described under Marker Adjustments, “Adjust- ments,” page 21.

Transporting

Towing the drill 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.
Do not tow a drill that,when fully loaded,weighs more than
1.5 times the weight of the towing vehicle.
Before transporting the drill check the following items.
1. Transport only with a tractor of proper size. See “Specifications,” page 59.
2. Hitch drill securely to tractor. Always use a locking­style pin sized to match holes in hitch and drawbar (minimum of 1-inch diameter).
3. Attach safety chain to an anchor on tractor capable of pulling drill.
4. Plug drill safety lights into tractor seven-pin connector.
5. Make sure drill is folded properly. Refer to Folding, page 14.
6. Lock openers up into road position. Refer to Opener Lock Up, page 20.
7. Secure cylinder lock channels on transport-cylinder rods and allow cylinders to settle against the chan­nels. Refer to Folding, page 14.

Marker Transportation

Always transport markers folded flat. Make sure second marker section rests securely on transport carrier.

Parking

For information on long-term storage, refer to Storage,Maintenance and Lubrication,” page 46.

Parking with Drill Unfolded

This drill has a negative tongue weight when unfolded and openers are raised. Lower parking stand, lower openers and re­move hydraulic down pressure before unhitching the drill in the unfolded position. Unhitching in the unfolded position with the openers raised could result in sudden elevation of the tongue, causing injury or death.
1. Remove jack from its storage location on top of tongue and pin it on post on left side of tongue as shown in Figure 1-1, page 9. Extend jack until weight of tongue is on jack.
2. Lower parking stands located on outer ends of drill by unpinning keeper pin and rotating stands down. See Figure 2-19. Place a block under foot of stand if it does not contact ground.
15565

Section 3 Adjustments

Section 3 Adjustments
This section covers basic field and maintenance adjust­ments. Before going to the field, set the seeding rate and adjust seeding depth. Check drive chains and disk scrap­ers periodically during the season.

Seed Rate Calibration

Calibrating the seeding rate requires four steps:
changing drive sprockets,
setting seed-rate handle,
positioning seed-cup doors, and
checking seeding rate.
Refer to the seed-rate charts. These charts list proper sprocket sizes and seed-rate-handle settings for various seeds and seeding rates.
The seed-rate charts are based on cleaned, untreated seed of average size and test weight. The charts are based on 9.5L-15, 6-ply, rib implement tires. Many factors will affect seeding rates including foreign material, seed treatment, seed size, seed weight, field conditions, tire pressure and test weight. You likely will need to make mi­nor adjustments. Set and check the seeding rate using the procedures below, then readjust the rate as necessary.
For correct drive type, refer to seed-rate charts beginning on page 25. The charts lists drive types as 1, 2, 3 or 4. Re­fer to the following table for correct-sized sprocket for each drive type.
To change drive types, loosen idlers and remove drive chain shown in Figure 3-1. Remove lynch pin and rear­range sprockets on shaft.
15559
Figure 3-1
Drive Type Sprockets
Reroute drive chain as shown in Figure 3-2. Set same drive type on both drill sections. Be sure chain is installed with the chain connector link retainer towards the center­line and the clip opening (split end) faces the opposite way of the chain travel.

Setting Seed-Rate Handle

There is a seed-rate-adjustment handle for each drill sec­tion. See Figure 3-3. Position handles to the setting indi­cated on the seed-rate charts. To adjust handle, loosen wing nut under handle and slide handle until indicator lines up with correct setting.
15561
Figure 3-3
Seed Rate Adjustment Handle

Positioning Seed-Cup Doors

For wheat and other small seeds, move seed-cup-door handles to highest position. For soybeans and other large seeds, lower handles to second position. If excessive seed cracking occurs, lower handles to third position. For seed­cup clean out, move handles to fourth, wide open. Make sure all handles are in the same position before drilling.

Checking Seeding Rate

You may be severely injured or killed by being crushed from a falling implement or openers. Always have transport locks in place and frame sufficiently blocked up when working on the drill.
1. Jack up drive gauge wheel(s) and rotate them to see that seed cups and drives are working properly and free from foreign material.
2. Check that your gauge-wheel tires are 9.5L - 15, 6-ply rib implement and properly inflated. Refer to Tire Infla- tion Chart, “Appendix,” page 60.
3. Record weight of an empty container large enough to hold seed metered for one acre.
4. Place several pounds of seed over three seed cups on an outside end of drill box. Pull seed tubes off of these three openers.
5. Turn drive wheel several times to fill seed cups. Turn wheel until seed drops to ground from each seed cup.
6. Place empty container under three tubes to gather metered seed.
7. Turn drive wheel until one acre is tallied on acremeter (203 wheel rotations). While turning, check that cups have plenty of seed coming into them.
8. Weigh metered seed. Subtract initial weight of con­tainer. Divide by three. Multiply by number of openers on your drill to determine total pounds-per-acre seed­ed. If this figure is different than desired, reset sprock­ets accordingly.
NOTE: You may want to repeat calibration procedure if your results vary greatly from seed-rate chart.
9. When drilling, check seeding rate by noting acres drilled, amount of seed added to drill and seed level in drill box. If you are seeding more or less than desired, adjust rate slightly to compensate for field conditions.

Fertilizer Rate Calibration

The 2S-2600F has chain drives powered off the gauge wheels to meter fertilizer. Adjust application rate by chang­ing drive sprockets.
Fertilizer application rates will vary with fertilizer type, den­sity and particle size. Relative humidity and field condi­tions can also affect application rates. The charts on page 30 are based on fertilizer with average particle size and a density of 65 pounds per cubic foot. Initially set rate ac­cording to charts, then calibrate drill to your material as described on this page.
Fertilizer metering is controlled by separate sprocket sets on each drill box. After setting and calibrating metering rate for one drill box, install same sprockets on other drill box.
1. Refer to fertilizer rate charts on page 30 to find correct sprocket sizes for your drill and desired meter rate.
IMPORTANT: The rate charts are for granular fertilizer with a density of 65 pounds per cubic foot. If you are applying fertilizer with a different density, use density conversion chart on page 30.
2. To switch between high and low range, loosen and slide idler sprocket out of chain shown in Figure 3-5. Remove lynch pin from end of shaft and install correct sprocket.
For high range, install 16-tooth sprocket and short-
en chain by removing 16-pitch strand.
For low range, install 44-tooth sprocket and length-
en chain by reinstalling 16-pitch strand.
Move idler sprocket back into place so chain has 1/4­inch slack.

3. To change driver/driven ratio, refer to Figure 3-6. Loosen and slide idler sprockets out of chain. Remove lynch pins from shafts. Place correct sprockets on
shafts. Store sprockets not used on ends of shafts. Reinstall chain and slide idlers back into place so chain has 1/4-inch slack.

4. Raise drill with tractor hydraulics so gauge wheels are off ground. Rotate gauge wheels to see that metering system is working properly and free from foreign ma­terial.
5. Check that your gauge-wheel tires are 9.5L x 15 and properly inflated. Refer to Tire Inflation Chart,“Ap- pendix,” page 60.
6. Place several pounds of fertilizer over three fertilizer feed cups on outside end of drill box. Pull fertilizer tubes off of these three disk openers.
7. Weigh an empty container large enough to hold fertil­izer applied to one acre.
8. Turn drive wheel until fertilizer starts to drop to ground.
9. Place container under the three tubes to gather me­tered fertilizer.
10. Turn drive wheel 203 rotations until one acre has been tallied on acremeter. Check that feed cups have plenty of fertilizer coming into them.
11. Weigh metered material. Subtract weight of empty container. Divide by three. Multiply by number of openers on your drill to determine total pounds me­tered per acre. If this figure is different than desired, reset sprockets accordingly.
NOTE: You may want to repeat calibration procedure if your results vary greatly from fertilizer rate chart.
12. When satisfied with metering rate, install same range, driver and driven sprockets on other drill box.
13. When drilling, check metering rate by noting acres drilled, amount of fertilizer added to drill and level of material in drill box. If you are applying more or less fertilizer than desired, adjust metering rate slightly to compensate for field conditions.

Density Conversion Chart

The fertilizer meter rate charts are based on fertilizer with a density of 65 pounds per cubic foot. If you are applying fer­tilizer of a different density, use the following table to convert application rate.
Density 45.00 50.00 55.00 60.00 65.00 70.00 75.00 80.00
Conversion Factor 1.45 1.30 1.20 1.10 1.00 0.93 0.87 0.81
Example: Your fertilizer has a density of 75 pounds per cubic foot, and you want to apply 100 pounds per acre. Multiply desired application rate by the conversion factor.
100 x 0.87 = 87

Seeding Depth

The 2S-2600 has double-disk openers with depth-control­ling press wheels mounted on floating opener frames. This system provides accurate depth control and seed place­ment over uneven terrain. When used with live closed-cen­ter tractor hydraulics the drill provides constant opener down pressure througha wide range ofopener movement. The following is an introduction to the seeding compo­nents and how they work.

Double Disk Openers

Each opener is mounted on a floating opener frame. Opener bodies are staggered for easy soil flow. Long and short opener bodies provide for 7" of stagger for planting through residue. All openers pivot on a common axis to maintain consistent depth as opener frames follow con­tours. A single spring provides down pressure necessary for the double disks to open a seed furrow. The spring al­lows openers to float down into depressions and up over obstructions. Individual openers can be adjusted to ac­count for tire tracks. Refer to page 35 for individual opener adjustment instructions.

Press Wheels

A press wheel is attached to each opener body. Press wheels provide two important functions.
First, press wheels close seed furrows and gently press soil over seed. To provide consistent seed firming, press wheels are free to move down from normal operating po­sition. This maintains pressing action even if opener disks encounter obstructions or hard soil.
Second, press wheels control seeding depth. To maintain a consistent depth, the relationship between the bottom of the opener disks and press wheel is fixed upwardly by an adjustable stop on each opener. The position of the adjust­able stop determines how deep seed is placed. Raising the stop increases seeding depth. Lowering the stop de­creases seeding depth. Refer to page 35 for press wheel adjustment.

Floating Opener Frames

Each drill section has an opener frame which pivots about the center line of the drill gauge wheels. These floating opener frames have the ability to rock the openers 15 de­grees up and 15 degrees down as a group. By pivoting at the gauge wheels, openers maintain a consistent depth as opener frames rock up and back.
Down pressure for each opener frame is provided by two cylinders working on a constant lever arm. When com­bined with live hydraulics, the cylinders provide constant down pressure across the width of each opener frame – regardless of how the frame is positioned. Two cylinders per opener framealong with specialtrunnions alsoprovide some ability for one end of an opener frame to rock inde­pendent of the other while maintaining constant opener down pressure across the frame. A pressure-control valve on each circuit allows you to adjust down pressure.
The opener frame has one adjustment point for two differ­ent operating positions – one for drilling with normal down pressure and another for drilling with high down pressure. Refer to Opener Frame Adjustment, page 35.

00 Series Opener Down Pressure

Crushing hazard – You will be seriously injured or killed if you are caught between raising openers and drill frame. Always stop tractor engine, set park bake, and remove key before adjusting or servicing openers. Keep all bystanders well away during drill operation.
Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or cardboard, NOT BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulicsystems. If an accident occurs, see a doctorimmediately.Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result.
Opener down pressure controls opener penetration and press-wheel soil firming. Use only enough down pressure to cut a furrow and maintain proper soil-firming over seed. Ex­cessive opener down force may cause bulldozing of the open­ers in light soil conditions, and will lead to premature wear on opener components.
The following chart shows the approximate force at the open­ers for a given pressure at the pressure control valve.

Active Hydraulic System

3. Once pressure is set, lock knob with lock disk. To run the drill with constant opener down pressure re­quires an Active Hydraulic System. An Active Hydraulic System requires a tractor with closed-center hydraulics or pressure/flow compensated hydraulics powered by a vari­able displacement hydraulic pump. (If you are not familiar with your tractor's hydraulics, consult your tractor dealer.)
IMPORTANT: Tractors with load-sensing hydraulics must use the bypass valve to operate the 2600-3S. Fail­ure to use the bypass valve can cause major tractor damage. Before adjusting opener down pressure, set bypass valve as explained under Setting the Bypass Valve, page 16.
NOTE: To run the drill on tractors with open-center hydrau­lics or on tractors with fixed displacement hydraulic pumps you must install a Great Plains kit, part number 194-143A. Contact your Great Plains dealer for ordering information. Refer to Non-Active Hydraulics System on this page.
To set down pressure:
1. Lower openers to the ground. Lock hydraulic lever for-
ward for constant hydraulic flow.
John Deere tractors with Sound-Gard ® Body: Use
lever lock clip, John Deere part number R52667, to lock lever forward. See your tractor dealer for clip pur­chase and installation.
John Deere 7000 Series tractors: Rotate valve
detent selector to motor position to lock lever in for­ward position.
John Deere 8000 Series tractors: Set timer to con-
tinuous. Push lever forward until detent clicks.
Case-IH Magnum tractors: Lock lever forward in
detent position. You may need to turn up detent pres­sure to its maximum setting. Do not tie hydraulic lever past detent position with a strap. See your tractor dealer for hydraulic-system details.
Other tractors: Lock lever forward in detent position.
You may need to turn up detent pressure to maximum or use a mechanical detent holder to hold lever for­ward. See your tractor dealer for proper means of pro­viding constant flow to openers.
2. Turn knob on pressure-control valve, see Figure 3-8.
While watching pressure gauge, turn knob until gauge shows desired pressure. Turn clockwise to increase pressure. Turn counterclockwise to decrease pres­sure.
There is one pressure-control valve for openerson the inside of drill and one for openers on the outside ends.
As a general starting point, set hydraulic down pres­sure to 800 psi. For most field conditions, adjust down pressure between 200 and 1400 psi. Setting the open­er down pressure above 1600 psi. will raise the drive wheels off the ground when the seed box is empty
Pressure Control Valves

Non-Active Hydraulic System

To run the drill on tractors with open-center hydraulics or on tractors with fixed displacement hydraulic pumps re­quires a kit (Great Plains part number194-143A). This kit utilizes a non-active hydraulic system which allows you to pressurize your openers down and lock inthat pressure on level ground by holding the opener frames in a fixed posi­tion.
To set down pressure:
1. Lower opener frames by pushing forward on tractor
hydraulic lever. Lock lever temporarily in this position while adjusting opener down pressure.
2. Turn knob on pressure-control valve, see Figure 3-8.
While watching pressure gauge, turn knob until gauge shows desired pressure. Turn clockwise to increase pressure. Turn counterclockwise to decrease pres­sure.
There is one pressure-control valve for openerson the inside of drill and one for openers on the outside ends.
As a general starting point, set hydraulic down pres­sure to 800 psi. For most field conditions, adjust down pressure between 200 and 1400 psi. Setting the open­er down pressure above 1600 psi. will raise the drive wheels off the ground when the seed box is empty causing skips and poor seed metering. Refer to the chart on page 33 for approximate force at the openers for a given pressure setting.

4. After opener down pressure is set, return tractor hy­draulic lever to neutral. This locks in the selected pres­sure, and opener frames will remain fixed in this position.
IMPORTANT: Open-center tractors and tractors with fixed-displacement pumps are not designed to provide a continuous supply of pressurized oil to remote valves. Locking hydraulic lever forward on these tractors can cause overheating of hydraulic oil and tractor damage. After setting opener down pressure, always return hy­draulic lever to neutral.
NOTE: On some tractors with very positive remote hydrau­lic checks, a slight increase in the reading on the pressure gauges may occur after the tractor remote lever is re­turned to neutral. This is caused by back pressure on the opener cylinders and should be ignored. The NET OPER­ATING PRESSURE on the opener cylinders is maintained at the pressure you selected while the tractor remote lever was held forward, not at the "apparently increased" pres­sure. Reactivating the tractor lever forward will confirm this.
Spring Down Pressure – Individual Openers
For planting in tire tracks, you can increase spring pressure on individual openers. To increase spring pressure, tighten flange nut at lower end of opener spring. See Figure 3-9. Each 1/4-inch adjustment adds about 13 pounds of force at opener disk. Do not tighten nut more than one inch. After adjusting, lock flange nut in place with jam nut.

00 Series Opener Depth

Press Wheel Adjustment

Set opener seeding depth by adjusting press-wheel height. To adjust, first raise openers slightly, then lift and slide T-handles on top of openers as shown in Figure 3-10. Adjust all press wheels to the same height.
For shallower seeding, slide T handles toward drill.
For deeper seeding, slide T handles away from drill.
Figure 3-10
Press Wheel Adjustment
NOTE: Opener down pressure controls soil-firming pres­sure on press wheel. Use press-wheel adjustments to reg­ulate seeding depth and opener-down-pressure adjustments to control opener penetration andsoil firming.

Individual Opener Height

You may need to lower an opener which runs in a tire track. To lower individual openers, move opener-pivot bolt to lower hole in opener mount. See Figure 3-11.

00 Series Opener Frame Adjustment

You can adjust opener frames between two operating positions–one for normal down pressure and one for high­er down pressure. The adjustment is near the opener­frame pivots. See Figure 3-12. There are three holes and two bolts. The bottom bolt (1) serves as the pivot. The top bolt (2) is for adjustment.
For normal drilling conditions, keep top bolt in second hole as shown in Figure 3-12. Use this setting when drilling with opener down pressure below 1600 psi.
When drilling with opener down pressure above 1600 psi, place top bolt in top hole on all four pivot points across drill.

00 Series Seed-Lok 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 lock up firming wheels, refer to Figure 3-14. Hook one end of chain in opener-body hole just above wheel arm (1). Pull firming-wheel arm (2) up as high as possible and wrap chain around arm. Hook other end of chain in a link. Leave no slack in chain; secure wheel arm in its highest position.

00 Series Disk Scraper Adjustment

To keep opener disks turning freely, dirt scrapers are mounted between disks to clean as the disks rotate. As field conditions vary, you may need to adjust scrapers. In damp conditions, lower scrapers. If openers are not turn­ing freely, raise scrapers.
To adjust, loosen 3/8-inch bolt shown in Figure 3-13 and move scraper as needed.

Crushing hazard – You will be seriously injured or killed if you are caught between raising openers and drill frame. Always stop tractor engine, set park bake, and remove key before ad­justing or servicing openers. Keep all bystanders well away during drill operation.
Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or card­board, NOT BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, see a doctor im­mediately. Any fluid injected into the skin must be surgically re­moved within a few hours or gangrene may result.
Opener down pressure controls opener penetration and press-wheel soil firming. Use only enough down pressure to cut a furrow and maintain proper soil-firming over seed. Excessive opener down force may cause bulldozing of the openers in light soil conditions, and will lead to premature wear on opener components.

NOTE: To account for additional compaction from drill and tractor tires, set pressure on inside openers slightly higher than outside openers.

Active Hydraulic System

To run the drill with constant opener down pressure re­quires an Active Hydraulic System. An Active Hydraulic System requires a tractor with closed-center hydraulics or pressure/flow compensated hydraulics powered by a vari­able displacement hydraulic pump. (If you are not familiar with your tractor's hydraulics, consult your tractor dealer.)
IMPORTANT: Tractors with load-sensing hydraulics must use the bypass valve to operate the 2600-3S. Fail­ure to use the bypass valve can cause major tractor damage. Before adjusting opener down pressure, set bypass valve as explained under Setting the Bypass Valve, page 16.
NOTE: To run the drill on tractors with open-center hydrau­lics or on tractors with fixed displacement hydraulic pumps you must install a Great Plains kit, part number 194-143A. Contact your Great Plains dealer for ordering information. Refer to Non-Active Hydraulics System on this page.
To set down pressure:
1. Lower openers to the ground. Lock hydraulic lever for­ward for constant hydraulic flow.
John Deere tractors with Sound-Gard ® Body: Use
lever lock clip, John Deere part number R52667, to lock lever forward. See your tractor dealer for clip pur­chase and installation.
John Deere 7000 Series tractors: Rotate valve
detent selector to motor position to lock lever in for­ward position.
John Deere 8000 Series tractors: Set timer to con-
tinuous. Push lever forward until detent clicks.
Case-IH Magnum tractors: Lock lever forward in
detent position. You may need to turn up detent pres­sure to its maximum setting. Do not tie hydraulic lever past detent position with a strap. See your tractor dealer for hydraulic-system details.
Other tractors: Lock lever forward in detent position.
You may need to turn up detent pressure to maximum or use a mechanical detent holder to hold lever for­ward. See your tractor dealer for proper means of pro­viding constant flow to openers.
2. Turn knob on pressure-control valve, see Figure 3-15. While watching pressure gauge, turn knob until gauge shows desired pressure. Turn clockwise to increase pressure. Turn counterclockwise to decrease pres­sure.
There is one pressure-control valve for openers on the inside of drill and one for openers on the outside ends.
As a general starting point, set hydraulic down pres­sure to 800 psi. For most field conditions, adjust down pressure between 200 and 1400 psi. Setting the open­er down pressure above 1700 psi. will raise the drive wheels off the ground when the seed box is empty causing skips and poor seed metering. Refer to the

Non-Active Hydraulic System

To run the drill on tractors with open-center hydraulics or on tractors with fixed displacement hydraulic pumps re­quires a kit (Great Plains part number194-143A). This kit utilizes a non-active hydraulic system which allows you to pressurize your openers down and lock inthat pressure on level ground by holding the opener frames in a fixed posi­tion.
To set down pressure:
1. Lower opener frames by pushing forward on tractor hydraulic lever. Lock lever temporarily in this position while adjusting opener down pressure.
2. Turn knob on pressure-control valve, see Figure 3-8. While watching pressure gauge, turn knob until gauge shows desired pressure. Turn clockwise to increase pressure. Turn counterclockwise to decrease pres­sure.
There is one pressure-control valve for openerson the inside of drill and one for openers on the outside ends.
As a general starting point, set hydraulic down pres­sure to 800 psi. For most field conditions, adjust down pressure between 200 and 1400 psi. Setting the open­er down pressure above 1700 psi. will raise the drive wheels off the ground when the seed box is empty causing skips and poor seed metering. Refer to the chart on page 33 for approximate force at the openers for a given pressure setting.
3. Once pressure is set, lock knob with lock disk.
4. After opener down pressure is set, return tractor hy­draulic lever to neutral. This locks in the selected pres­sure, and opener frames will remain fixed in this position.
IMPORTANT: Open-center tractors and tractors with fixed-displacement pumps are not designed to provide a continuous supply of pressurized oil to remote valves. Locking hydraulic lever forward on these tractors can cause overheating of hydraulic oil and tractor damage. After setting opener down pressure, always return hy­draulic lever to neutral.
NOTE: On some tractors with very positive remote hydrau­lic checks, a slight increase in the reading on the pressure gauges may occur after the tractor remote lever is re­turned to neutral. This is caused by back pressure on the opener cylinders and should be ignored. The NET OPER­ATING PRESSURE on the opener cylinders is maintained at the pressure you selected while the tractor remote lever was held forward, not at the "apparently increased" pres­sure. Reactivating the tractor lever forward will confirm this.
Spring Down Pressure – Individual Openers
For planting in tire tracks, you can increase spring pressure on individual openers. To increase spring pressure, tighten flange nut at lower end of opener spring. See Figure 3-16. Each 1/4-inch adjustment adds about 13 pounds of force at opener disk. Do not tighten nut more than one inch. After adjusting, lock flange nut in place with jam nut.

Marker Adjustments

Speed Adjustment

Adjust folding speed for dual markers with hex adjustment screws on the sequence-valve body as shown in Figure 3-
17. There is one adjustment screw for raising speed (1) and one for lowering speed (2). You can identify adjust­ment screws by markings stamped in valve body.
Turn adjustment screws clockwise to decrease folding speed and counterclockwise 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 the folding speed, tighten jam nuts on hex adjustment screws to hold settings.

Marker Chain

There are two, interrelated adjustments for the marker chain. Make these adjustments in the following order. Re­fer to Figure 3-20.
1. Lifting Slack. With marker unfolded, back full-thread­ed adjustment bolt (1) down until head extends as little as possible. Slowlyfold marker while observing disk. If marker disk slides across ground more than a foot be­fore chain and linkage lifts it up, the chain is too long.
Shorten chain one or two links by moving clevis (2). Check adjustment by repeating folding process.
If chain is too short when marker is unfolded, it will prevent end of marker from dropping into field depres­sions, causing skips in your marker line. Correct this condition by lengthening chain one or two links at cle­vis (2).
2. Folding Slack. Fold marker. Use full-threaded adjust- ment bolt (1) to take slack out of chain while marker is folded. Extend bolt until there is no chain slack. Lock bolt in this position by tightening nuts (3) on either side of upright channel (4).

Disk Adjustment

There are two ways you can change the mark left by the marker disk. Refer to Figure 3-21.
1. Disk Angle. To change angle of cut, loosen 1/2-inch bolts holding disk assembly. Rotate disk assembly as desired.
2. Direction of Cut. To change direction of cut and throw dirt either in or out:
a. Reverse blade and depth band by remounting lug
bolts on disk hub.
b. Reverse angle of assembly by removing two 1/2-
inch bolts holding disk assembly. Turn disk as­sembly one-half turn. Reinstall 1/2-inch bolts and set disk angle.

Toolbar Height

Toolbar height is factory set and normally will not require adjustment. If you tear down the drill for repair or if the tool­bar is visibly not level, spacer washers on vertical pivot pins allow for a small amount of toolbar-height adjustment.
To check toolbar height, park drill on a level surface. Mea­sure from ground to horizontal pivot pin. See Figure 3-26. If dimension on either side of drill varies more than 1/4 inch, adjust toolbar height.
To adjust toolbar height, repositions spacer washers (1). See Figure 3-26. First lower openers and set enough opener down pressure to help balance frame. Raise tool­bar by removing spacer washers from top of the vertical pivot and placing them on bottom side of pivot. Lower tool­bar by removing spacer washers from bottom of vertical pivot and placing them on top of pivot.

Maintenance

Proper service and maintenance are the keys to long im­plement life. With careful and systematic inspection, you can avoid costly maintenance, downtime and repair.
You could be severely injured or killed by being crushed from a falling implement. Always have opener transport locks and cyl­inder lock channels in place when working on implement.
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 injured, seek medical assistance from a doctor that is familiar with this type of injury. Foreign fluids in the tissue must be surgically removed within a few hours or gangrene will result.
This drill has a negative tongue weight when unfolded and openers are raised. Lower parking stand, lower openers and re­move hydraulic down pressure before unhitching the drill in the unfolded position. Unhitching in the unfolded position with the openers raised could result in sudden elevation of the tongue, causing injury or death.

Openers

If the raising or lowering times of the opener are noticeably slower, check the inline filter and clean if needed. See Fig­ure 5-1. .
For S/N DD1215- 2004-:
1. To disassemble unscrew end cap of filter (7) opposite direction of flow. Remove large (2) and small (3) springs from inside the filter. Pull the poppet (4) up out of filter. Using a hook, pull up filter seat (5) and screen (6).
2. Clean filter screen with solvent and compressed air.
3. When reassembling push filter seat (5) and screen (6) back into filter. Place poppet (4) in filter with arrow tip down. Replace springs (2) (3) and end cap (7).
For S/N DD1216+ 2005+:
1. To disassemble unscrew end cap of filter (1). Remove top retaining washer and screen.
2. Clean filter screen with solvent and compressed air or replace if needed.
3. When reassembling put screen into filter. Place retain­ing washer on top of filter and screw on end cap (1).
S/N DD1215- 2004-

1. After using your drill for several hours, check all bolts to be sure they are tight. Lubricate areas noted under Lubrication, page 48.
2. Remove excess slack from chains. Clean and use chain lube on all roller chains as needed.
3. Always maintain proper air pressure in drill tires.
4. Keep disk scrapers properly adjusted.
5. Clean drill on a regular basis. Regular and thorough cleaning will lengthen equipment life and reduce maintenance and repair.
6. Replace any worn, damaged or illegible safety labels by obtaining new labels from your Great Plains dealer.

Marker Breakaway Protection

The marker arm is attached to the marker body with a 3/8­inch, grade 2 shear bolt. It is identified as a grade 2 by hav­ing no marks on the head.
If excessive force is applied to the marker during opera­tion, the shear bolt will break and allow the marker arm to swing away. If the bolt breaks, replace it with a grade 2 bolt to prevent marker damage.

Storage

Store drill where children do not play. If possible, store drill inside for longer life.
1. Thoroughly clean drill boxes and seed cups. Do not store drill with fertilizer or seed-treatment residue in boxes and cups. Refer to 2S-2600F Clean Out, page
46.
2. Lubricate and adjust all roller chains.
3. Lubricate areas noted under Lubrication, page 48. Take special care to oil seed-cup-drive sprockets in the square bore.
4. Lock opener frames up for transport or disconnect seed and fertilizer hoses from openers. Leaving seed hoses connected when storing drill with openers low­ered will cause permanent stretching and cracking of hoses.

Flat Folding Marker

The hydraulically operated, flat-fold markers leave a line for you to follow on the next field pass. Markers are sold as sin­gle units for mounting on the left end on your drill or as dual units for mounting on both ends of your drill. Dual markers are plumbed together with a sequence valve so you can op­erate both markers on the same hydraulic circuit. Both mark­er options come with a double-selector valve, allowing you to tie the marker hydraulic circuit into the fold hydraulic circuit.

00 Series Seed-Lok Firming Wheel

The spring-loaded Seed-Lok firming wheels press seed di­rectly into the bottom of the furrow, assuring the best seed-to­soil contact. The firming wheels promote even emergence since seeds are planted and firmed at the same depth. The wheels bolt directly to the scraper mount on your standard drill openers.

Two Outlet Hydraulic Kit

To operate all drill functions, the standard 2S-2600 requires a tractor with three remote valves. Tractors with two remote valves can be used with the two-outlet hydraulic kit. Using a double-selector valve mounted on the drill tongue, this kit com­bines the transport-lift and opener-lift circuits.
To operate a drill equipped with markers on a tractor with two remote valves, you must install two kits – one to combine the transport-lift and opener-lift circuits and one to combine the marker and fold circuits.
