Introduction Great Plains Mfg., Inc. Introduction 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 the machine. Description of Unit The 6- and 8-row, pull-type planter is a towed planting implement. The frame consists of 7-by-7-inch tubing. Planting rates are adjustable by changing sprockets on the planter transmission or contact drive. Row units are mounted on the frame. Seed hoppers are standard on the row units; chemical hoppers and granular-chemical applicators are available. Springs on each row unit provide down pressure needed for the double-disk openers to make a seed trench. Finger-pickup meters singulate and dispense seed from the hopper and deliver it to the trench. Seeding depth is controlled by side gauge wheels on the openers. Closing wheels or disks close the trench. With an optional 5-by-7-inch fertilizer bar, the planter can be outfitted with dry or liquid fertilizer application and tillage attachments. Intended Usage Use this implement for planting row crops in large fields. Tow the implement behind an agricultural tractor at speeds of less than 20 mph. The unit is designed for conventionally tilled fields but can be used in no- or minimum-till conditions if outfitted with optional tillage attachments.

Section 2 Operating Instructions Secure wing nuts as shown in Figure 2-3. 14949 Figure 2-2 Chemical Hopper 16866 Marker Operation Markers can be raised simultaneously but must be lowered one at a time. If both markers are required down at the same time, run one marker down, momentarily start to raise it, reverse the hydraulic lever and lower the opposite marker. Holding the lever down will force both markers down. On a tractor where the oil flow cannot be controlled, the rate of flow of oil from the tractor may be greater than the rate at which the marker cylinder can accept it. The tractor hydraulic control lever will have to be held until the cylinder reaches the end of its stroke. This occurs most often on tractors with an open-center hydraulic system. On tractors with a closed-center hydraulic system, the tractor s hydraulic flow control can be set so the tractor s detent will function properly. Liquid Fertilizer Operation! WARNING! Agricultural chemicals can be dangerous if not selected and handled with care. Always read and follow directions supplied by the chemical manufacturer. For accurate metering, keep pump speed below 125 rpm. To operate the pump, the discharge manifold must be in the forward position as shown in Figure 2-3. Pumps are shipped in the rearward position. To position the manifold forward for operation, loosen the wing nuts on the manifold and pull the manifold forward. Figure 2-3 Discharge Manifold Forward Position In Use When the pump is not in use, reposition the pump manifold to prolong the life of the hoses in the squeeze pump. To reposition the discharge manifold to the rearward position, loosen the wing nuts and push the manifold back as shown in Figure 2-4.

Section 3 Adjustments Section 3 Adjustments Planting Rate Transmission Adjustment To change the planting population, change the sprocket combination on the transmission. 1. Refer to Planting Rates for Finger Pickup Corn Meters, page 18, or Planting Rates for Brush Meters, page 19, for proper sprocket combination for your desired planting population. 2. Remove cover from transmission by loosening knob on cover. See Figure 3-2. 3. Loosen carriage bolt and flange nut on idler plate. Rotate idler plate and move idlers out of chain. 4. Remove chain. Place correct sprockets for desired planting rate on shafts. Store all unused sprockets on storage bracket. 5. Reroute chain over idlers and sprockets. 6. Turn idler plate counterclockwise to take up all but 1/4- inch slack out of chain. Retighten carriage bolt and flange nut on idler plate. 7. Replace transmission cover and hand tighten knob. 2-to-1 Drive Reduction The charts on page 18 and page 19 are based on a 15- tooth, driven sprocket in the contact-wheel drive. To reduce planting rates by one-half, switch to 28-tooth sprocket. See Figure 3-1. Checking Planting Population After setting transmission, always field check planting population as follows. 1. Release spring pressure on closing wheels or disks. 2. Tie up closing disks or wheels to hopper support using a chain or heavy wire. Lock up optional Seed-Lok wheels. 3. Adjust planting depth to a shallow setting. 4. Plant at a normal speed for a short distance. 5. For 30-inch rows, measure 17 feet 6 inches (one-thousandth of an acre). 6. Count the number of seeds in one row over the measured distance. 7. Multiply the number of seeds counted by 1000. This gives you total population. Example 30-inch row spacing Measure 17 feet 6 inches 24 seeds over measured distance in one row 24 X1000 = 24,000 plant population per acre If the planting population is significantly different than desired, make the following checks. Double check the sprocket combination in the transmission. Refer to Planting Rates for Corn Meters, page 18, or Planting Rates for Brush Meters, page 19. Check air pressure in the gauge-wheel tires. Refer to Tire Inflation Chart, Appendix, page 56. Check for meter malfunction or excessive contactdrive-wheel slippage. Refer to Troubleshooting, page 34.

Section 3 Adjustments Great Plains Mfg., Inc. Brush Meters, Cotton Discs Meters equipped with the 12 cell acid-delinted hill-drop cotton discs will plant from 3 to 6 seeds per cell because of variations in cotton seed size. Determine which hill spacing is desired and select the transmission ratio that is closest to that hill spacing on chart. To determine the average seeds per hill and hills per acre do the following field check: 1. Measure 1/1000 of an acre. (1/1000 acre = length of row 17 5 for 30 widths). 2. Multiply the average seed per hill by hills per acre. Example: 4 seeds per hill x (13 hills x 1000) = 52,000 Transmission Sprockets Drive Planting Rates 30-Inch Row Width Driven Speed Range (mph) 12 Cell Hill-drop Cotton, Acid-delinted Hills/Acre Average Hill Spacing (inches) 17 28 2 to 8 16,186 12.9 17 27 2 to 8 16,785 12.5 17 26 2 to 8 17,431 12.0 19 28 2 to 8 18,090 11.6 19 27 2 to 8 18,760 11.1 17 24 2 to 8 18,883 11.1 17 23 2 to 8 19,704 10.6 19 25 2 to 8 20,261 10.3 19 24 2 to 8 21,105 9.9 23 28 2 to 8 21,898 9.5 19 23 2 to 8 22,022 9.5 24 28 2 to 8 22,850 9.2 24 27 2 to 8 23,697 8.8 17 19 2 to 8 23,853 8.8 24 26 2 to 8 24,608 8.5 26 28 2 to 8 24,755 8.4 24 25 2 to 8 25,592 8.2 26 27 2 to 8 25,671 8.1 23 23 2 to 8 26,659 7.8 Transmission Sprockets Drive Planting Rates 30-Inch Row Width Driven Speed Range (mph) 12 Cell Hill-drop Cotton, Acid-delinted Hills/Acre Average Hill Spacing (inches) 27 26 2 to 8 27,684 7.6 24 23 2 to 8 27,818 7.5 25 23 2 to 8 28,977 7.2 19 17 2 to 8 29,795 7.0 27 24 2 to 8 29,991 7.0 28 24 2 to 8 31,102 6.7 23 19 2 to 8 32,271 6.5 28 23 2 to 8 32,454 6.5 24 19 2 to 8 33,674 6.2 25 19 2 to 8 35,077 6.0 23 17 2 to 8 36,068 5.8 26 19 2 to 7 36,480 5.7 27 19 2 to 7 37,883 5.5 28 19 2 to 7 39,287 5.3 26 17 2 to 7 40,772 5.1 27 17 2 to 7 42,340 4.9 28 17 2 to 7 43,908 4.8 20 PT6030 and PT8030 Pull-Type Planter 401-032M-B 4/12/05

Section 3 Adjustments Granular Chemical Rates The application rate is determined by: the size of the opening on the meter and travel speed. Application rates will also vary with the consistency and composition of the chemicals, air temperature, humidity and ground speed. Because of the wide variability in application rates, you must field check the actual rate of application for each meter.! WARNING! Agricultural chemicals can be dangerous if not selected and handled with care. Always read and follow directions supplied by the chemical manufacturer. To adjust the chemical rate: 1. Select a meter setting as a starting point. If the chemical manufacturer recommends ounces per 1000 linear row feet or pounds per acre for a given band width and row spacing, use the recommended meter setting as a starting point. If the chemical manufacturer recommends pounds per acre for complete (broadcast) coverage, you must calculate the pounds per acre for your band width and row area. Refer to Conversion from Broadcast to Row Coverage, page 21. If the meter setting is not available from the chemical manufacturer, use Granular Chemical Rate Charts, starting on page 23. The charts are approximate and are based on a ground speed of 5 mph. Use these charts as a starting point for setting the meter. 2. Turn meter knob until the display shows the correct number. See Figure 3-3. 3. Fill the hoppers with chemical. 4. Attach a plastic bag to each chemical diffuser. 5. Drive 500 feet at a normal planting speed. 6. Weigh the contents of the bag in ounces. 7. Multiply weight by 2.2 to determine the pounds per acre. 8. If necessary, adjust the meter setting and repeat steps. Figure 3-3 Meter Knob 17929 Conversion from Broadcast to Row Coverage If the chemical manufacturer recommends pounds per acre for complete (broadcast) coverage, you must reduce the pounds per acre rate to match for your band width and row area. Use the following formula to find the pounds per acre for your band width and row spacing. A X B/C = Pounds per Acre Application Rate Where: A = Recommended rate in pounds per acre for complete (broadcast) coverage B = Band width in inches C = Row spacing in inches NOTE: Measure the actual band width applied in your conditions and use this width in your calculations. Example The chemical manufacturer recommends 20 pounds per acre for complete broadcast coverage. The band width is 14 inches. The row spacing is 30 inches. A = 20 B = 14 C = 30 20 x 14/30 = 9.3 pounds per acre Turn meter knob to setting recommended for 9.3 pounds per acre. IMPORTANT: If a significant difference in rate is observed between rows, the meter may require recalibration. Refer to Recalibrating Chemical Meter, page 22. 4/12/05 PT6030 and PT8030 Pull-Type Planter 401-032M-B 21

Section 3 Adjustments Great Plains Mfg., Inc. Recalibrating Granular Chemical Meters If the metering rate differs significantly between rows, recalibrate the meters. Refer to Figure 3-4. 1. Remove and empty hopper. Turn hopper upside down. 2. Turn meter knob (1) to 10. 3. Loosen screws (2) in metering gate. 4. Insert calibration tool (3). 5. Readjust meter setting to 04. 6.

Section 3 Adjustments Liquid Fertilizer Attachment! WARNING! Agricultural chemicals can be dangerous if not selected and handled with care. Always read and follow directions supplied by the chemical manufacturer. On machines equipped with the squeeze pump option, the rate of liquid fertilizer application is determined by the combination of sprockets on the squeeze pump driven and drive shafts. When changing sprocket combinations, make sure sprockets are in alignment, sprocket retaining collars are tight and chain tension is sufficiently restored. The chart on this page provides approximate application rates. Actual rates will vary with temperature and the particular fertilizer being used. NOTE: If placed too close to the seed, certain analysis of fertilizer may cause germination or seedling damage especially if used in amounts in excess of fertilizer manufacturer s recommendations. Check with your fertilizer dealer or manufacturer for the correct amount and placement.

IMPORTANT: Fertilizer application rates can vary from the weights in the charts. Make field checks to assure you are applying fertilizer at the desired rate. Use the following instructions to check the exact number of pounds your fertilizer attachment will actually deliver on a 30-inch row spacing. 1. Remove a hose from one of the fertilizer hoppers and attach a container under the opening. 2. Engage the fertilizer attachment and drive forward for 174 feet. 3. Weigh the amount of fertilizer caught in the container and multiply that amount by 100. The result will be the pounds of fertilizer delivered per acre when planting in 30-inch rows. To assure proper application check the gauge tires and contact drive tire for proper inflation, see Tire Inflation Chart in Appendix on page 55. IMPORTANT: Before applying fertilizer make sure that augers are rotating correctly and are positioned for your desired rate setting. See Figure 3-6 and Figure 3-7.

Section 3 Adjustments Meter Drive Adjustments The meter clutch and meter-input shaft must be aligned. Misalignment will cause meter malfunction and excessive meter-housing wear. Periodically check vertical and horizontal alignment of meter clutch and meter-input shaft. Refer to Figure 3-8. 1. Latch hopper onto hopper support. 2. Check that roll pin (1) in end of the meter-input shaft is centered. When centered, equal amounts of the roll pin will protrude from both sides of the shaft. 3. Rotate meter-input shaft so that roll pin is vertical. 4. Rotate the drive coupler (2) on meter clutch so that the slots are vertical. 5. Release meter clutch to engage meter-input shaft. 6. If shafts are aligned vertically, the drive coupler will engage with meter-input shaft freely and the roll pin will extend equally on each side of the drive coupler. Disengage the clutch and repeat steps, checking for horizontal alignment. Row Unit Adjustments Down Pressure Springs provide the down pressure necessary for opener disks to open a seed trench. The springs allow the row unit to float down into depressions and up over obstructions. You can adjust down pressure individually for each row unit. Use only enough down pressure to cut the seed trench and maintain proper soil-firming over seed. Excessive down pressure will lead to premature wear on rowunit components. To adjust, lift T-handle shown in Figure 3-9. Move T-handle back to increase spring pressure. Move T-handle ahead toward tractor to decrease spring pressure. 17718 Figure 3-9 Row Unit Spring Adjustment Refer to the charts below for the amount of spring pressure at the opener for each spring setting.

Section 5 Maintenance and Lubrication Section 5 Maintenance and Lubrication Maintenance Proper servicing and maintenance is the key to long implement life. With careful and systematic inspection, you can avoid costly maintenance, downtime and repair. Always turn off and remove the tractor key before making any adjustments or performing any maintenance.! WARNING! You may be severely injured or killed by being crushed under a falling planter. Always install cylinder stops before working on planter. To install the stops, refer to Figure 5-1. Raise planter to transport position. Pivot cylinder stop into position on wheel module cylinder rods. Lower planter onto stop. Install bent pin and secure with cotter pin. Check latches and other fasteners on the planter to prevent failures in the field. 5. Check all bolts and replace worn parts on the planter. Check that all safety decals and reflectors are legible. Replace if damaged. Refer to Safety Decals, Important Safety Information, page 5. Replacing Shear Pins Refer to Figure 5-2. The cotter pins (1) that connect the shafts to the transmission will shear when an excessive load is put on the shafts. Infrequent or improper lubrication causes binding of moving parts within the planter. This binding will cause the cotter pins to shear, thus preventing breakage of planter parts. Check for binding by turning the drive shaft with all seed hoppers installed and seed meters engaged. If the drive shaft is hard to turn, disengage one seed-meter clutch at a time to find the problem clutch. Improper shaft alignment can also cause pins to shear. Refer to Shaft Alignment, page 38, to check shaft alignment. When the drill shaft can be turned freely by hand, replace the cotter pin. IMPORTANT: Replace cotter pins with cotter pins of the same size. Do not replace with other type pins. 16889 Figure 5-1 Cylinder Stop! WARNING!

If excessive force is put on the marker during operation, the bolt will break, allowing the marker arm to swing away rather than cause damage to the marker. IMPORTANT: The breakaway bolt is a 5/16-by-1 1/2- inch grade 5 on planter only (GP 802-012C). If it breaks, it must be replaced by an equivalent grade 5 bolt to prevent marker damage. 4/12/05 PT6030 and PT8030 Pull-Type Planter 401-032M-B 43
