13 Section 3 Basic Operation Section 3 Basic Operation Drill Preparation And Field Operations 1. Be certain that your rib implement tires are 11L x 15" for the 20' drills. Also check for proper inflation as listed in Tire Inflation Chart, Section 2, page Load seed box with beans. You should use cleaned beans to get the best results. You should always have the drill hitched securely to a tractor and lowered before loading. 3. Your drill comes equipped with an acremeter and it should be mounted on the outside of the left gauge wheel jackshaft. It will accumulate the total acres drilled with the drill. In order to find out the acres covered, write down the beginning reading and subtract it from the ending reading for the total acres planted. 4. Make sure that the feed cup door adjustment handle, is in the second 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 the drill out of the ground when turning at ends of field rows and other short-radius turns. 8. Never allow anyone to ride on the drill. 9. Maximum seeding speed should vary according to soil conditions. Transporting! CAUTION! This drill should never be pulled faster than 20 miles per hour! 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 extreme care must be taken to allow for safe clearance. Parking Unhitching The following steps should be done when preparing to store the drill or unhitch it from the tractor. See also Storage, Section 7, page 19, for additional information on the long term storage of your drill. 1. It is best not to unhitch the drill from the tractor with a full seed box. Empty the drill if possible. 2. Select a parking spot for the drill on a level, solid area. 3. Unpin and rotate the optional front stands down into position. Replace pins as shown in Figure If the ground is soft, place a board or plate under the stand to increase the ground contact area. 5. Lower the 3-Point hitch until the drill is on the ground. 6. Extend or retract the top link of the tractor until the top 3-point pin is free. Remove the pin. Next, remove the pins from the lower links. Before transporting the drill, follow and check the following items This drill can be transported with a full box of beans. It is best NOT to do this unless necessary because the increased weight does increase the chances for problems on the road. Do not exceed 20 miles per hour. NOTE: In order to maintain steering control, ballast may have to be added to tractor front end. To determine the amount of ballast required refer to your tractor s operator manual. If drill is used with an optional hitch, make sure that hitch is securely attached to the draw bar of the tractor and that the hitch safety chain has been securely attached Optional Parking Stand Figure 3-1 4/18/05 Great Plains Mfg., Inc Three-Point Soybean Machine M -11

15 Section 4 Adjustments Section 4 Adjustments Gauge Wheel Adjustments The planter rows on the drill are adjusted by raising or lowering the gauge wheels. Raise the drill out of the ground and loosen the jam nut located near the bottom clevis of the gauge wheel turnbuckle, Figure 4-1. This turnbuckle is threaded to alloweasy gauge wheel adjustment. By lengthening the Opener Down Force Standard Spring Package The standard down force spring package, consists of 2 non-adjustable springs applying approximately 90 lbs. of down force. Optional Medium and Heavy Duty Spring Package The medium and heavy duty spring packages consist of 2 or 4 adjustable springs, respectively. The medium duty package can be adjusted from approximately 100 to 200 lbs. down force. The heavy duty package can be adjusted from approximately 200 to 400 lbs. of down force. Spring Adjustments All spring adjustments must be made with the drill in the fully raised position. The spring package is adjustable from 90 lbs. to 325 lbs. of down force when the parallel arms are horizontal. Consult the "Down Force Pressure Chart". NOTE: The maximum down force stated before is reached when the parallel arms are all the way up. To adjust the spring tension, lift the plunger by pulling up on the roll pin handle and sliding the handle adjustment assembly into the appropriate hole, see Figure 4-2. Gauge Wheel Turnbuckle Figure turnbuckle the gauge wheel is lowered, also lowering the openers. By shortening the turnbuckle the gauge wheel is raised, also raising the openers. After adjusting, be sure the turnbuckle on both gauge wheel arms have the same pin center dimensions. Your 3-Point Drill is designed to run level to the ground when in planting position. Minor adjustments may be required to achieve the desired bean placement. After any gauge wheel adjustments have been made, use the top link to set box and frame level to the ground. Two springs can be purchased at your Great Plains Dealer to make the medium duty package into a heavy duty package or two springs can be removed from the heavy duty package to make a medium duty package. Add or subtract springs by removing the snap ring at the end of the spring pivot rod. Slide the rod inward to add or remove a spring from each side. Then attach or remove the other spring end on the hex bar support. Reinstall the spring rod and snap ring on each side. 4/18/05 Great Plains Mfg., Inc Three-Point Soybean Machine M -13

Row Unit Mounted Coulter Figure Depth Adjustment The seeding depth of the row unit is controlled by 2 walking gauge wheels located next to the disks. Adjust the planting depth as follows: 1. Raise the drill to remove weight from the gauge wheel. 2. Raise the T-handle and move it forward to decrease the seeding depth, see Figure 4-4. Moving the handle rearward increases the seeding depth. Small increments of depth adjustment can be made by walking the T-handle from side to side. 3. After one row is set to the desired depth, move the T-handle on the other rows to the same location. Adjustment Bar Figure 4-2 Row Unit Mounted Coulter The optional coulter allows the drill to penetrate tough ground conditions. It is recommended that either the medium duty or heavy duty spring package be used in conduction with this coulter. Coulter Adjustments 1. To adjust the coulter vertically, loosen the 3/4" jam nut and the 3/4" x 3" long hex bolt, see Figure By turning the cam hex, rotate the cam casting to set the desired height. For wavy coulter blades, it is recommended that the coulter blade should be run even to 1" below the disks on the row unit. 3. Tighten the bolt and jam nut to torque values in "Section 2 Torque Value Chart" on page T-Handle Adjustment Figure 4-4 1" x 12" Closing Wheel Adjustments The 1" X 12" closing wheel option can be adjusted for down force, alignment, and offset Three-Point Soybean Machine M Great Plains Mfg., Inc. 4/18/05

17 Section 4 Adjustments Closing Wheel Down Force Adjustment Adjust the closing wheel down force to permit proper closing of the seed trench. It is recommended to start with the T-handle in the first of 4 notches, see Figure 4-5. If the seed trench is not closing move the handle to the next notch back and try again. Keep moving the handle back until the seed trench is closing, by doing this eliminates unnecessary down force and compaction. In some field conditions, the T-handle can be left in the forward slot to minimize down force. Closing Wheel Offset The 1x12 wheels can be offset to help prevent trash from plugging the closing wheels. If the closing wheels are not offset, the wheels should be located in the front holes of the press wheel arm. To offset the wheels, do as follows: 1. Raise drill slightly to remove weight on the closing wheels. 2. Remove the 3/4 bolt attaching the wheel, see Figure Move the wheel to the rear hole & attach with the 3/4" bolt. Tighten the bolt to the correct torque value listed in "Section 2 Torque Values Chart" on page 6. Closing Wheel Adjuster Figure Closing Wheel Alignment (Refer to Figure 4-6) If one closing wheel is running in the seed trench or the wheels are not centered over the seed trench, adjust the closing wheels as follows: 1. Raise the drill slightly to remove weight from the closing wheels. 2. Loosen the two 1/2" mounting bolts. 3. Turn the press wheel adjuster cam left or right to center the wheels over the seed trench. 4. Tighten the 1/2" mounting bolts to the correct torque value listed in "Section 2 Torque Values Chart" on page Closing Wheel & Offset Figure 4-7 Closing Disk Adjustments The closing disk options consists of two disks and a 6 1/2 x 12 press wheel. The disk down pressure can be adjusted to provide closing of the seed trench. To adjust the down pressure, ratchet the spring cam to the next cam height by turning the head of the support bolt clockwise. Refer to Figure 4-8. Closing Wheel Alignment Figure Closing disk & Tube Holes Figure /18/05 Great Plains Mfg., Inc Three-Point Soybean Machine M -15

18 Section 4 Adjustments Seed Lok The seed lok option provides additional seed to soil contact. The seed lok is spring loaded and does not require adjusting. In some wet and sticky conditions the wheel may accumulate soil and may require removal of the seed lok until conditions improve. The seed lok is attached to the shank with a 1/2" clevis pin, see the Figure 4-9. To remove the seed lok, remove the clevis pin and pull down on the seed lok mount. Reattach in the reverse order. IMPORTANT! If your drill has more than one gearbox, make sure both are shifted to the same drive type setting. The drive type setting on the two brass indicator plates for the 20 drill are opposite of each other. Be sure that the side of the brass indicator plate with the "4" is the end closest to the center of the drill Seed Rate Adjustment Figure 4-10 Gear Box Ratios: Setting 2 is 2.06 Times Faster Than 1 Setting 3 is 3.08 Times Faster Than 1 Setting 4 is 5.03 Times Faster Than 1 Seed Lok Assembly Figure 4-9 Adjusting The Seeding Rate NOTE: Seeding rates will vary greatly with variations 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 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 feed cups at the outboard drive end of one seed box. b. Pull the seed tubes out of these row units. c. Raise the drill off the ground. If using a hitch, be sure to insert transport lock pins or turn 90 hydraulic 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 Three-Point Soybean Machine M Great Plains Mfg., Inc. 4/18/05

19 Section 4 Adjustments 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 sure to check the three feeder cups to make sure each cup has plenty of beans coming into it. f. Weigh the beans which has been metered. Divide 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, set your feed cup adjustment lever accordingly. 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-position feed 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: Do not open the cup to the wide open position with beans in the box unless complete clean out is desired.

20 Section 4 Adjustments Marker Adjustments Chain Adjustment There are two chain adjustments. These adjustments are interrelated and should be done in the following order. Refer to Figure 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 keep the end of the marker from 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. Lock the bolt in this position by tightening the nuts (3) on either side of upright channel (4). IMPORTANT: To prevent marker damage, the marker arm is attached to the marker body with a 3/8- inch, grade 2 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 C. Disk Adjustment The field mark left by the marker disk may be changed by adjusting angle of cut or direction of cut. 1. Angle of Cut. Refer to 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 Figure 3-2 Disk Angle Shear Bolt 2. Direction of Cut. The disk may be mounted to throw dirt in or out for different marks in different soil conditions. Refer to. To change the direction of cut: a. Reverse the disk by removing the four lug bolts on the disk hub. Remount the depth band and lug bolts. b. Turn the entire disk assembly by removing the two 1/2-inch bolts and turning the assembly one-half turn. Reinstall the 1/2-inch bolts and set the disk angle as desired Figure 3-1 Marker Chain Adjustment Three-Point Soybean Machine M Great Plains Mfg., Inc. 4/18/05

21 Section 4 Adjustments 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.! CAUTION! You may be injured if hit by a folding or unfolding marker. Markers may fall quickly and unexpectedly if the hydraulics fail. Never allow anyone near the drill when folding or unfolding the markers Figure 3-3 Direction of Cut Reversed Folding Speed Adjustment Each marker is equipped with a needle valve to control how fast the marker operates. The needle valve is located in the hydraulic hose line at the rod end of the marker cylinder as shown in Figure 3. Turn the adjustment knob clockwise to slow the speed down and counterclockwise to speed it up. Adjustments should be made for safe operating speeds at the tractors operating RPM. Excessive folding speed could damage the marker and may void the warranty. Faster Slower Needle Valve! 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. 1. Check that the tractor hydraulic reservoir if full. 2. With the markers in field position, crack the hose fittings at the base end of both cylinders. With your tractor at an idle speed, engage hydraulic lever until oil seeps out around one of the cracked fittings. Tighten that fitting. 3. Crack the hose fitting at the ram end of the cylinder which seeped oil. Reverse tractor hydraulic lever until oil seeps out around the fitting. Tighten the fitting. 4. Engage hydraulic lever until oil seeps out around the base-end fitting on the other cylinder. Tighten the fitting. 5. Crack the remaining ram-end hose fitting. Reverse hydraulic lever until oil seeps out around the fitting. Tighten fitting. IMPORTANT: Never attempt to bleed an O-ring type fitting. Instead, choose a pipe or JIC fitting nearby Fold and unfold the markers slowly to work all air out of the circuit.

22 Section 5 Maintenance & Lubrication Section 5 Maintenance & Lubrication 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. Feed cup drive sprocket should be oiled in its 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 decals by obtaining new 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 C. Disk Bearings. Normally, 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 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. Lubricate all 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 cup adjustment lever back and forth in order to get the oil 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.

26 Section 6 Troubleshooting 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 a. Check tire pressure. Proper inflation is listed on page 6 in Tire Inflation Chart. b. Check tire size. Proper size is 11L x 15". c. Liquid seed treatment will affect seeding rate if the 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. Check tire pressure. Proper inflation is listed in Section 2 Tire Inflation 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. Grain box not emptying evenly a. Certain models do not have the same number of seed cups between each divider of bulkhead. The section with the larger number of cups will empty sooner. b. If your drill has multiple boxes, check adjustment levers on each box to see that they are set on the same indicator number. Feeder cup sprockets locked up or twisted a. Check for foreign matter lodged in one or more feeder drive shaft feeder cups. b. Liquid insecticide from bean has dried within the feed cup. Remove the build up by disassembling each feed cup and scrape the foreign substance from the turning surfaces. NOTE: Liquid inoculant should be applied with caution and care should be taken to clean the feeder system after planting treated beans Three-Point Soybean Machine M Great Plains Mfg., Inc. 4/18/05
