Section 1 Safety Rules
Section 1 Safety Rules
Most accidents are the result of negligence and care­lessness, usually caused by failure of the operator to follow simple but necessary safety precautions. The fol­lowingsafetyprecautions are suggested to help prevent such accidents. The safeoperation of any machinery is abigconcern to consumers and manufacturers.Your20’ 3-PointSoybeanMachine has been designedwithmany built-insafetyfeatures.However, no one should operate this product before carefully reading this Operators Manual.
!
General Operation & Repair
1. Never allow the 20’ 3-Point Bean Machine to be operat­ed by anyone who is unfamiliar with the operation of all functions of the drill. All operators should read and thor­oughly understand the instructions given in this manual prior to moving the drill.
2. Make sure safety rules are understood before operating machinery or tractor.
3. Never permit any persons other than the operator to ride on the tractor.
4. Never permit any persons to ride on or stand near the drill while it is in operation.
5. Regulate your speed to the field conditions, maintaining complete control at all times.
6. After repairing or adjusting, make sure all tools and parts are removed from the implement before attempting to operate it.
7. Do not grease or oil machine while it is in operation.
8. Loose fitting clothing should not be worn as it may catch in moving parts.
9. Never dismount from a moving tractor.
10. Do not leave the tractor or the implement unattended with the engine running.
11. Do not stand between the tractor and the implement dur­ing hitching.
12. Detach and store implements in an area where children normally do not play. Stabilize implements by using suit­able supports and block wheels.
13. If a hydraulic leak develops, correct it immediately. Es­caping hydraulic oil can have extremely high pressure. A stream of high pressure oil may easily penetrate the skin as with modern needle-less vaccination equipment - but with the exception that hydraulic fluid may cause blood poisoning. It is imperative that the connections are tight and that all lines and pipes are in good condition. If an injury is caused by the escaping hydraulic fluid, see doc­tor at once!
14. Use a piece of cardboard or wood to detect leaks of hy­draulic oil under pressure.
15. Be sure to relieve all hydraulic pressure before disconnec­tion any lines or pipes between the implement and the trac­tor hydraulic system. Keep all guards and shields inplace.
Transporting
1. Use good judgement when transporting tractor and im­plements on the highway. Always maintain complete con­trol of the drill.
2. Limit transport speed to 20 mph. Transport only with a farm tractor of sufficient size and horse power.
3. Always make sure flashing safety lights, “Slow Moving Vehicle” emblem, and reflectors are in place and visible prior to transporting the drill on public roads.
4. Know your state and local laws concerning highway safety and regulations. Comply with these laws when transporting machinery.
5. Use warning flags or approved warning lights at night and during other periods of poor visibility. Do your best to prevent highway accidents.
Tire Handling & Repair
1. Tire changing can be dangerous and should be pre­formed by trained personnel using the correct tools and equipment.
2. Do not re-inflate a tire that has been run flat or seriously under inflated. Have it checked by qualified personnel.
3. When removing and installing wheels, use wheel han­dling equipment adequate for the weight involved.
Safety Decals
1. Your 20’ 3-Point Soybean Machine comes equipped with all safety decals in place. They were designed to help you safely operate your 20’ 3-Point Bean Machine. Read and follow their directions.
2. Keep safety decals clean and legible.
3. Replace all damaged or missing safety decals. To order newsafety decals goto your Great Plains Dealerand refer to the parts section for safety decal package part number.
4. Replace these decals whenever they become worn or un­readable. To instal new safety decals:
a. Clean the area the decal is to be placed b. Peel backing from the decal. Press firmly on to sur-
face being careful not to cause air bubbles under the decal.

It will accumulate the total acres drilledwiththedrill.In order to find out the acres cov­ered,writedown the beginning reading and subtract it from the ending readingfor the total acres planted.
4. Make sure that the feed cup door adjustment han­dle,isinthesecond handle position and is the same on each cup across the drill.
5. If you notice excessive cracking on large beans, ad­just all feed cup door handles to the third position.
6. Never back up with openers in ground. If you do, check all openers to be sure none are clogged.
7. This drill is not designed to be turned sharply in the field. Always lift thedrill out of the ground when turn­ingatendsoffieldrowsandother short-radius turns.
8. Never allow anyone to ride on the drill.
9. Maximum seeding speed should vary according to soil conditions.
Check to see that the transport tires on the hitch have
the proper inflation as listed in the "Tire Inflation Chart" Section 2, page 6.
Comply with all Federal, State and Local Safety Laws
when traveling on public roads.
Remember, the drill is wider than the tractor and ex-
treme care must be taken to allow for safe clearance.

Adjusting The Seeding Rate
NOTE:Seeding rates will vary greatlywithvariations in sizes of the beans. Although the seeding rates listed in this manual are based on an average bean size, we recommend that you test and adjust your drill using the procedures listed below to help insure an accurate seeding rate.
1. Rotate each gauge wheel to see that feed cups and drive are working properly and are free from foreign matter.
2. To adjust your seeding rate, first you must decide which drive type (gearbox) setting you need from the seeding charts on next pages. The charts list drive type settings 1, 2, 3 or 4. The drive system uses a 4 speed gear box located above the drive wheels. Move the selector handle on the gearbox until the desired drive type number appears in the handle’s window, Figure 4-100. Rotate the tires a few turn to confirm the gearbox has engaged.
3. There are many factors which will affect seeding rates: bean treatment, weight of bean, size of bean, surface condition of bean, and tire configuration, pressure and slippage. Minor adjustments will prob­ably be needed to compensate for above factors.
4. The pounds-per-acre in the seed charts are based on 20' drills having 11L x 15" rib implement tires.
5. The large differences in bean size and treatment can cause a wide variation in actual seeding rates. The seed rate charts on the following pages are based on average size seed. This may differ from the seed you are using. Use the seed rate charts as a guide. Set the pounds-per-acre desired at the in­dicator number for your row spacing and complete the following procedure to calibrate the drill for your specific seed.
a. Place several pounds of seed over three of the
feedcups at the outboard drive end ofoneseed
box. b. Pull the seed tubes out of these row units. c. Raise the drill off the ground. If using ahitch, be
sure to insert transport lock pins or turn 90˚ hy-
draulic lock valve, depending on hitch style to
prevent injury should hydraulic system allow
drill to lower while working around it. d. Place a container under the three seed tubes to
gather the seed as it is metered.

e. Rotate the drive gauge wheel until one acre has
been tallied on the acremeter. This will be approximately 283 rotations on a 20' drill.Be sureto check thethreefeedercups to makesure each cup has plenty of beans coming into it.
f. Weigh the beans which has been metered. Di-
vide by three. This will give you the ounces/ pounds metered by each feed cup. Multiply by the number of openers on your drill to arrive at the total pounds-per-acre your drill would meter at that setting. If this figure is different than de­sired,setyourfeedcupadjustmentleveraccord­ingly.
6. You may want to repeat the calibration procedure if the results of your calibration vary greatly from the suggested setting contained in this manual.
REMEMBER: Tire size, tire air pressure, and field condi­tions also affect seeding rates. Be certain that your rib implement tires are 11L x 15" for the 20' drill. Also check the “Tire Inflation Chart” in Section 2, page 6, for prop­er inflation. When planting, check the amount of beans you are using by noting acres planted, amount of beans added to drill, and level of beans in planter box. If you
suspect that you are planting more or less than desired, and you have accurately calibrated the drill to your beans, you may need to adjust the seeding rate slightly to compensate for your field conditions.
NOTE:This drill is equipped with a four-positionfeed cup door on each feed cup. The "highest" handle po­sition is for wheat and other small grain seeds, the "middle" position is for soybean and other large bean seeds. Should excessive cracking occur to the large seeds, drop the handle to the "lowest" position. The wide open position will allow complete clean out of the feed cup. MAKE SURE all handles are in the same position before planting.
NOTE:Donotopenthecuptothewideopenposition with beans in the box unless complete clean out is desired.

Marker Adjustments
Chain Adjustment
There are two chain adjustments. These adjustments are interrelated and should be done in the following or­der. Refer to Figure 3-1.
1. Lifting Slack. Startwith 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.
Ifthechainistoo short when the markeris unfolded, it will keep the end of the markerfrom dropping into field depressions. Correct this 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. Lockthebolt in this position bytightening thenuts (3) on either side of upright channel (4).
IMPORTANT:T opreventmarkerdamage,the mark­er arm is attached to the marker body with a 3/8­inch, grade2 shear bolt. See Figure 3-1. If it breaks, you must replace it with a grade 2 bolt. The bolt is Great Plains part number 802-253C.
Disk Adjustment
The field mark left by the marker disk may be changed by adjusting angle of cut or direction of cut.
1. AngleofCut.Referto Figure 3-2. To change the an­gle of cut loosen the two 1/2-inch bolts holding the disk assembly. Rotate the disk assembly as desired.

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.
!
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 the markers.
Escaping fluid under pressure can have sufficient pressure to penetrate the skin causing serious injury.Avoid the hazardby relievingpressurebeforedisconnecting hydrauliclines. Use a piece of paper or cardboard, NOT BODYPARTS,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 removedwithin a few hours or gangrenewill re­sult.

Maintenance
Proper servicing and adjustment is the key to the long life of any farm implement. With careful and systematic inspection, you can avoid costly maintenance, time and repair.
1. After using your drill for several hours, check all bolts to be sure they are tight.
2. Adjust idlers to remove excess slack from chains. Clean and use chain lube on all roller chains as needed.
3. Feedcup drivesprocketshouldbe oiledinits square bore. Move feed cup adjustment lever away from the sprocket as far as possible in order to get the oil back into the square.
5. Always maintain the proper air pressure in the rib implement tires.
6. Disk scrapers should be kept properly adjusted.
7. Replace any worn, damaged or illegible safety de­calsbyobtainingnew decals from your Great Plains Dealer.
Marker Maintenance Breakaway Protection. The marker arm is attached to
the marker body with a 3/8-inch, grade 2 shear bolt. If it
breaks, replace the shear bolt with a grade 2 bolt. The bolt is Great Plains part number 802-253C.
Disk Bearings. Normally,the disk hub bearings needto be repacked every 2 or 3 years. If the grease seal cap is damaged or missing, disassemble and clean the hub. Repackwith grease and install a new seal or grease cap.
Storage
1. Clean the drill as necessary. Be sure that the bean boxes are completely cleaned before storing.
2. Lubricate and adjust all roller chains.
3. Lubricateall pivots as indicated in the following Illus­trations.
4. Feed cup drive sprocket hub should be oiled in its square bore. Squirt oil on to the square feed cup shaft and move feed cupadjustment lever back and forthin order to get theoil back into the square. This is most important before putting the drill in storage.
5. Disconnect seed hoses from parallel linkage open­ers. Permanent elongation and premature cracking of hoses may occur if stored connected
6. Store the drill inside if possible for longer drill life.

The speed-change gearbox is lubricated and sealed at the factory. Under normal conditions, it does not require maintenance or lubrication.
If you open the gearbox for repair, repack all gears and around the shaft bearings with least 7 ounces of gear lube (Great Plains part number 788067).
It is important to keep moisture and dirt out of the gear­box. Inspect the rubber seals on the gearbox drive and shifter shafts. Replace seals if necessary.
Before bolting them back together, spread a very thin coat of anaerobic sealant (such as Loctite 525) on the gear case mating surfaces.
IMPORTANT:Use sealant sparingly! Excess seal­ant may squeeze off surface and lock bearings or gears.

Section 6 Troubleshooting
Problem Solution Uneven bean spacing or uneven stand a. Check for trash in seed cup.
b. Check to see if seed tubes are plugged. c. Reduce ground speed. d. Check planter disks to see they turn freely. e. Use faster drive type speed and close feed cup flutes to a more
narrow position.
Planter disks not turning freely a. Check for trash or mud buildup on disk.
b. Check row frame for possible damage.
Actual seeding rate is different than desired.
Excessive seed cracking
Acremeter doesn’t measure accu­rately
Uneven seeding depth Press Wheel not compacting the soil
as desired Grain box not emptying evenly a. Certain models do not have the same number of seed cups be-
Feeder cup sprockets locked up or twisted
a. Checktire pressure. Proper inflation is listed on page 6 in “Tire In-
flation Chart”. b. Check tire size. Proper size is 11L x 15". c. Liquid seed treatmentwillaffectseeding rateifthe chemicals build
up in feed cup. Unless cleaned regularly,this build up can cause
increased torque and breakage of the feed shaft. d. Check drive type. See "Section 4 Seed Rate Chart" page 17. e. See instructions on calculating seed rate.
Change drive type to a slower speed and open flutes in feed cup to a wider posi­tion.
a. Checktire pressure. Proper inflation is listed in “Section 2 Tire In-
flation Chart” on page 6. b. Check tire size. Proper size is 11L x 15". c. Check planting operation for excessive overlap or gaps between
passes. d. Loose soil conditions and slippage will cause variations in acres
registered. e. To check accuracy of acremeter. See "Section 4 Seed Rates"
page 16.
Check to see that all planter drills are adjusted the same. Check the spring tension bolt on the back of the press wheel arm. The spring
pressure can be adjusted heavier or lighter.
tween each divider of bulkhead. The section with the larger num-
ber of cups will empty sooner. b. If your drill has multiple boxes, check adjustment leverson each
box to see that they are set on the same indicator number. a. Check for foreign matter lodged in one or more feeder driveshaft
feeder cups. b. Liquid insecticide from bean has dried within the feed cup. Re-
movethe build up by disassemblingeachfeedcup and scrapethe
foreign substance from the turning surfaces. NOTE: Liquid inocu-
lant should be applied with caution and care should be taken to
clean the feeder system after planting treated beans.

Press Wheels and planters plugging a. Drilling in damp or wet conditions may increase this problem.
b. DO NOTback up drill in field, or stop and allow drill to roll back-
wards with openers in the ground.
Gauge Wheel leans to left or right a. Realignbracketswhere gauge wheelisattachedtomainframeby
adjusting the mounting bolts.
b. Checkto see if gauge wheel axle bearing are securely attached to
gauge wheel arm.
Hydraulic adaptors cracking a. JIC fittings do not require high torque.
b. Always use liquid pipe sealant when adding or replacing pipe
threadhydraulicfittings. Plastic sealant can crackfittingsandplug hydraulic lines. JIC and O-ring fittings do not require sealant. O­ring fittings require a thin coat of oil on the O-ring. IMPORTANT: When using sealant on pipe threads the friction between the threads is reduced; therefore, be certainnot to over tighten caus­ing damage to the cylinders, valves,or fittings.
Hydraulic Marker functioning improp­erly
Drill is not pulling level (parallel to ground, front to rear)
a. Check all hose fittings and connections for air & oil leaks. b. The chain on the folding 3-Section marker should be slack when
the marker is both fully extended and fully raised. c. Check tractor hydraulic oil level. d. Check all bolts and fasteners. e. Open needle valve, if provided. Cycle markers slowly and reset
needle valveif plugged. a. Readjust 3-point top link to level drill. b. If using pull-package equipped with a sliding top link, increase
opener spring pressure in order to rock drill forward.
