Tractor Requirements
Your drill is designed and factory set for category III trac­tors.
Hitching Tractor to the Drill
Gauge-Wheel Adjustment
Gauge-wheel adjustments affect the operating height of your drill, and drill height directly affects the working range of the openers.The drill must be adjusted so your openers can travel up and down and follow the ground contour.
Before using in the field, adjust your drill so the opener mount tube runs 18 1/4 inches above ground. You likely will need to make further adjustments later to compensate for field conditions. Refer to Gauge-Wheel Adjustments, “Adjustments,” page 11 for how to make gauge-wheel adjustments.
Bleeding Marker Hydraulics
If you install or replace part of optional markers, you must bleed air from the marker hydraulics. Your markers will not fold properly with air in the hydraulic circuit.
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, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene will result.
DANGER!
Do not place any body part between the tractor and drill during hitching.
1. Raise or lower the 3-point links as needed.
2. Install the lower hitch pins.
3. Pin the top link to the drill and adjust so it remains loose in normal field conditions.
4. Check that all three-point links are securely pinned, then slowly raise the drill. Watch for cab interference.
5. Unpin the parking stands as shown in Figure 1-1. Ro­tate the stands up into field position and repin.
12151
1. Be sure tractor hydraulic reservoir if full.
2. With the markers unfolded, crack the hydraulic hose fittings at the base end of the cylinders. With your trac­tor at an idle speed, activate your tractor hydraulic valve until oil seeps out around the hose ends. Re­tighten the fittings.
3. Repeat step 2 for the hose-end fittings at the rod end of the cylinders.
4. Fold and unfold the markers slowly to work all the air out of your marker hydraulics. Use caution when fold­ing and unfolding the marker for the first time and check for pinching and kinking of hoses.

Section 2 Operating Instructions
Section 2 Operating Instructions
The following section will give you general operating pro­cedures. Experience, machine familiarity and thefollowing information will lead to efficient operation and good work­ing habits. Always operate farm machinery with safety in mind.
Prestart Checklist
1. Carefully read “Important Safety Information,” page
1.
2. Lubricate the drill as indicated under Lubrication, “Maintenance and Lubrication,” page 22.
3. Check all tires for proper inflation as indicated on Tire Inflation Chart,“Appendix,” page 29.
4. Check all bolts, pins and fasteners. Torque as speci­fied on Torque Values Chart,“Appendix,” page 29.
5. Check the drill for worn or damaged parts. Repair or replace them before going to the field.
6. Check hydraulic hoses, fittings and cylinders for leaks. Repair or replace them before going to the field.
7. Check disk scrapers for proper adjustment. Refer to Disk Scraper Adjustment,“Adjustments,” page 19.
8. Rotate both gauge wheels to see that seed cups and drive are working properly and free from foreign mate­rial.
Field Operation
CAUTION!
Do not allow anyone to ride on the drill.
1. Hitch the drill to a suitable tractor before filling the drill. Refer to Tractor Requirements and Hitching Tractor to Drill,“Preparation and Setup,” page 8. Adjust the top link so it remains loose in normal drilling conditions.
2. Set and calibrate the seeding rate as explained under Seeding Rate,“Adjustments,” page 12.
3. Load box with clean seed.
4. Record the acremeter readout. Subtract the initial reading from later readings to determine acres drilled.
5. Check that the seed-cup-door handles are set the same across the drill. Refer to Seeding Rate,“Adjust- ments,” page 12.
NOTE: If you notice excessive cracking on large seeds, adjust all seed-cup doors to a wider setting. Use the wid­est setting for seed-cup clean out only.
6. Lift the drill out of the ground when turning at end of the field and for other short turns. Do not back up with openers in ground. If you do, check all openers for clogging.
Shaft Monitor Operation
To operate the optional shaft monitor, turn system on by activating on-off switch on monitor head. If the seed-cup shaft stops for 20 seconds or more, an alarm will sound and the light on the monitor will flash.
The 20-second delay is to prevent nuisance alarms when turning at the end of the field. If a failure does occur and the alarm sounds, remember you have traveled for 30 seconds without planting.
Transporting
WARNING!
Never tow the drill faster than 20 mph.
You can transport the drill with a full box of grain, but it is not recommended. The increased weight will make steer­ing more difficult and increase the risk of road accidents.
To maintain steering control, you may need to add ballast to your tractor front end. Refer to your tractor operator’s manual for the amount of ballast required.
Before transporting the drill, check the following.
1. Check that all 3-point hitch links are securely pinned to the tractor.
2. Comply with all federal, state and local laws when traveling on public roads.
3. Remember that the drill is wider than the tractor. Al­ways allow for drill clearance.
Transporting with Markers
Always transport the drill with the markers folded. Check that the second marker section rests securely on the transport carrier. If it does not, refer to Marker Adjust- ments,“Adjustments,” page 19 for transport carrier ad- justments.

Section 3 Adjustments
Section 3 Adjustments
Gauge-Wheel Adjustment
Gauge-wheel adjustments affect the operating height of your drill, and drill height directly affects the working range of the openers. The drill must be adjusted so your openers can travel up and down and follow the ground contour. Ini­tially adjust the gauge wheels so the bottom of the opener mounting tube runs 18 1/4 inches above ground.
To adjust drill height:
1. Loosen the jam nut near the bottom clevis of each gauge-wheel turnbuckle. Refer to Figure 3-1.
10548
Figure 3-2
Normal Spring Rod Setting, Drill Level
IMPORTANT: Do not use the links to adjust opener depth. To achieve desired seeding depth, refer to Seed- ing Depth, “Adjustments,” page 12.
10546
Figure 3-1
Gauge Wheel Turnbuckle
2. Bolt the upper clevis in the upper mounting hole.
3. Set the turnbuckle length. Turn the turnbuckle to shorten or lengthen as necessary. Initially set the length to 20 3/8 inches between pin centers to achieve the 18 1/4-inch dimension mentioned above. When adjusting the turnbuckle, remember:
•Lengthening the turnbuckle raises the drill and allows less downward float of the openers.
•Shortening the turnbuckle lowers the drill and allows less upward float of the openers.
NOTE: Remember that lowering the drillincreases the risk of opener damage on rocks or obstructions.
4. After adjusting both turnbuckles, be certain they are the same length, then tighten the jam nuts.
5. After setting the turnbuckles, level the drill with the top hitch link. When the drill is level, the gap between the spring-rod casting and the cross bolt will be about 2 inches. See Figure 3-2. This is a general dimension that will vary with the amount of down pressure re­quired for your planting conditions.
For some drill applications, you may want to equip your drill with two spring-loaded links (part number 120-106A) or a slotted link (part number 120-171A). Mount the links in the top hole of the gauge wheel bracket as shown in Fig­ure 3-3. You do not need to adjust the spring-loaded or slotted links.

Section 3 Adjustments
Great Plains Mfg., Inc.
Adjusting Seeding Depth
Your drill is designed to run level to the ground when low­ered into seeding position. You may need to make minor adjustments to achieve desired seeding depth.
Press Wheels
Opener depth is controlled by the height of its press wheel. Changing the height of the press wheel automatically changes the seeding depth of the opener.
To adjust press-wheel height, lift up on the T-handle and slide it forward or back. Refer to Figure 3-4.
12100
Figure 3-4
Press Wheel Adjustment
Down-Pressure Springs
Each opener can be adjusted individually for increased or decreased down pressure. Increased down pressure aids opener penetration in hard soils and tire tracks. De­creased down pressure may prevent openers from plug­ging in wet soil.
To adjust opener down pressure, remove the W clip at the bottom of the spring shown in Figure 3-5. Place the clip in a higher spring-rod hole for increased pressure. Place the clip in a lower hole for decreased pressure. If an opener is running too deep at the lowest pressure setting, the W clip can be removed completely.
Bedded Irrigation
If your drill is outfitted with the bedded irrigation option, you can adjust the height of openers that run in irrigation furrows.
When running the drill in a level field, mount the openers in the top hole (1).
To lower the openers for irrigation furrows, move the open­er pivot bolt (2) to a lower hole in the opener mount. Low­ering the pivot bolt one hole lowers the opener body 2 1/2 inches.

Seeding Rate
Calibrating the seeding rate requires four steps: arranging the drive sprockets, setting the seed-rate adjustment han­dle, positioning the seed-cup door, and checking the seed­ing rate.
Refer to the seed-rate charts starting on page 15. These charts list the 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 rates are based on 9.5L x 15 rib implement tires. Many factors will affect seeding rates including foreign material, seed treatment, seed size, field conditions, tire pressure and test weight. Minor adjustments likely will be needed. Set and check the seeding rate using the procedures below, then re-adjust the rate as necessary.
Before setting the seeding rate, rotate the drive gauge wheel to see that seed cups and drive are working proper­ly and free from foreign material.

1. Change Drive Sprockets
Refer to the seed-rate charts for the correct drive type–1, 1A, 2 or 2A. Figure 3-7 shows the sprocket ar­rangement for each drive type.
c. To change the jackshaft sprocket shown in Figure
3-9, remove the set screws and slide the sprock­ets so the correct-sized sprockets are aligned. Reinsert set screws.

3. Position Seed-Cup Doors
For wheat and other small seeds. move the seed-cup­door handles to the highest position. For soybeans and other large seeds, lower the handles to the sec­ond position. If excessive seed cracking occurs, lower the handles to the third position. Move the handles to the fourth, wide-open position for seed-cup clean out. Make sure all handles are in the same position before drilling.

4. Check Seeding Rate
a. Record the weight of an empty container large
enough to hold the seed metered for one acre.
b. Place several pounds of seed over three seed
cups on an outside end of the drill box. Pull the seed tubes off these three openers.
c. Raise the drill off the ground.
d. Turn the gauge wheel a few turns to fill the cups
with seed. Turn wheel until seed drops to the ground from all three cups.
e. Place a container under the three seed tubes to
gather the seed as it is metered.
13867
f. Turn the drive gauge wheel until one acre has
been tallied on the acremeter (200 rotations on a 27-foot drill or 182 rotations on a 30-foot drill). Check that the three seed cups have plenty of seed coming into them.
g. Weigh the metered seed. Subtract the initial
weight of the empty container. Divide by three for the amount metered by each seed cup, then multiply by the number of drill openers for the pounds-per-acre seeding rate. If this figure is different than desired, adjust the seed-rate han­dle and recheck the rate.
NOTE: If your results vary greatly from the charts, you may want to repeat the calibration procedure.
When satisfied with the rate, set the same seeding rate on the opposite drill box by repeating steps 1 through 3.
Small Seeds Attachment
To calibrate the seeding rate on the optional small seeds attachment, follow these steps.
1. Refer to Figure 3-13 for the proper small-seeds sprocket arrangement given different drive types on the main drill box. Arrange the sprockets on the small-seeds attachment according to which drive type you will use on the main drill box.
NOTE: For accurate metering on the small seeds at­tachment, the main drill box sprockets must be set to drive type 1, 2 or 2A.
2. Set the seed-rate adjustment handle on the small seeds attachment as indicated by the chart on Small Seeds Attachment Seed Rate Chart, page
17.
3. Calibrate the small seeds attachment to your mate­rial by following the steps under Check Seeding Rate, page 14.

Marker Adjustments
Chain Adjustment
There are two chain adjustments. These adjustments are interrelated and should be done in the following order. Re­fer to Figure 3-14.
1. Lifting Slack. Start with the marker unfolded. Back the full-threaded adjustment bolt (1) down until the head extends as little as possible. Slowly fold the marker, ob­serving the motion of the disk. If the disk slides across the ground more than about a foot before the chain and linkage lifts it up, the chain is too long. Shorten the chain by moving the clevis (2) in one or two links. Check the adjustment by repeating the folding process.
If the chain is too short when the marker is unfolded, it will prevent the end of the marker from dropping into field depressions. Correctthis condition by moving the clevis (2) one or two links toward the end of the chain to make it longer.
2. Folding Slack. After completing the adjustment in step one, fold the marker. Extend the full-threaded adjust­ment bolt (1) until the slack is out of the chain. Lock the bolt in this position by tightening the nuts (3) on either side of upright channel (4).
Disk Adjustment
The field mark left by the marker disk may be changed by adjusting disk angle or direction of cut.
Disk Angle. Refer to Figure 3-15. To change the angle of cut loosen the two 1/2-inch bolts holding the disk assem­bly. Rotate the disk assembly as desired.

Figure 3-15
Disk Angle
Direction of Cut. The disk may be mounted to throw dirt in
or out for different marks in different soil conditions. Refer to Figure 3-16. To change the direction of cut:
1. Reverse the disk by removing the four lug bolts on the disk hub. Remount the depth band and lug bolts.
2. Turn the entire disk assembly by removing the two 1/2­inch bolts and turning the assembly one-half turn. Re­install the 1/2-inch bolts and set the disk angle as de­sired.

Section 3 Adjustments
Speed Adjustment
The markers are equipped with hex-head screws for ad­justing folding speed. The screws are on the sequence­valve body as shown in Figure 3-17. There are two screws–one for folding speed (1), the other for unfolding speed (2). Turn the adjustment screws clockwise for slow­er folding or counterclockwise for faster folding. Adjust to a safe speed. Excessive speed could damage the markers and void the warranty.

Seed-Lok
The optional Seed-Lokfirming 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. Remove or install the wheels as field conditions warrant.
Disk Scraper Adjustment
To keep the double-disk openers turning freely, dirt scrap­ers are mounted between the disks to clean as the disks rotate. A scraper is shown in Figure 3-18. As field condi-

Great Plains Mfg., Inc.
General Maintenance
Proper servicing and adjustment 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 maintenance. Securely block raised drill before working under or around it.
1. After using your drill for several hours, check all bolts to be sure they are tight. Periodically check and se­cure all bolts, pins and fasteners. Tighten as specified on Torque Values Chart,“Appendix,” page 29.
2. Clean or replace any fittings that will not take grease. Lubricate the drill as noted under Lubrication, this page.
3. Adjust idlers to remove excess slack from chains. Clean and use chain lube on all roller chains as need­ed.
4. Always maintain correct tire pressure. Refer to Tire In- flation Chart,“Appendix,” page 29.
5. Check disk scrapers for proper adjustment. Refer to Disk Scraper Adjustment,“Adjustments,” page 19.
6. Replace any worn, damaged or illegible safety decals at once. Refer to Safety Decals,“Important Safety In- formation,” page 4, for correct decal placement. Ob­tain new decals from your Great Plains dealer.
Marker Maintenance
Under normal conditions, the disk hub bearings need to be repacked every 2 or 3 years. If the grease seal cap is dam­aged or missing, disassemble and clean the hub. Repack with grease and install a new seal or grease cap.
Storage
Store the drill where children do not play. If possible, store the drill inside for longer life.
1. Clean the drill as necessary. Be sure the seed boxes are cleaned completely before storing.
2. Adjust and oil all roller chains. Lubricate the drill at all points indicated under Lubrication, this page.
IMPORTANT: Be sure the seed-cup drive sprocket is oiled before the drill is stored. Squirt oil onto the square seed-cup shaft and move adjustment handle to get the oil into the square.
3. Check all bolts, pins, fitting and hoses. Tighten, repair or replace parts as needed.
4. Check all moving and soil-contact parts for wear or damage. Make notes of any parts needing repair.
5. Use Great Plains touch-up paint to cover scratches, chips and worn areas to prevent rust.
