Before using the drill, you must adjust the drill hitch to match your tractor drawbar height, install and bleed the drill hydraulics, and hitch the drill to your tractor. Prestart Checklist 1. Read and understand Important Safety Information beginning on page 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 Lubrication, page Check that all safety labels and reflectors are correctly located and legible. Replace if damaged. Refer to Safety Labels, Important Safety Information, page Inflate tires to recommended pressure as listed on Tire Inflation Chart, Appendix, page 36. Tighten wheel bolts as specified on Torque Values Chart, Appendix, page 36. Adjusting the Drill Hitch Adjust the drill hitch to match tractor drawbar height so your drill runs level in the field. 1. Back your tractor up as if hitching to the drill. Park the tractor several yards from the drill. Set the brake and turn off the tractor. 2. Crank the drill jack until the top of the drill box is parallel with the ground. Compare the height of the drill hitch to your tractor drawbar. 3. If necessary, adjust the drill hitch to match your tractor drawbar. See Figure 1-1. To adjust the hitch, remove the 3/4-inch nuts, bolts and washers. Reverse and reinstall the clevis hitch. Installing Drill Hydraulics The drill requires a hydraulic cylinder with a 3 1/2- or 4-inch bore, an 8-inch stroke and a 20 1/4-inch pin-to-pin retracted length. A cylinder, hoses and fittings are available through your Great Plains dealer. For ordering information, refer to Hydraulic Cylinder Kit, Options, page 33. If hydraulics have not been installed, follow these steps. 1. Mount the cylinder as shown in Figure 1-2. Pin the base end to the lug on the drill tongue. Pin the ram end to the floating lug on the opener frame. Secure the pins with cotter keys, hair-pin clips or other pins. Figure 1-2 Hydraulic Cylinder Installed Install elbow fittings in the cylinder ports. 3. Connect the female end of the hydraulic hoses to the fittings. 4. Route the hoses along the drill tongue and through the hose holder Figure 1-1 Adjusting Clevis Hitch 11/7/ End-Wheel Drill M 9

12 Section 1 Preparation and Setup Hitching to the Tractor! WARNING! You may be severely injured or killed by being crushed under the tractor or between the tractor and drill hitch. Do not stand between the tractor and drill when the tractor is moving.! WARNING! Negative tongue weight can cause immediate elevation of the tongue when unhitching the implement. To prevent serious injury or death: Lower the openers before unhitching. Always be certain the implement is hitched securely to the tractor drawbar before raising the openers. 1. Slowly back the tractor toward the drill. When within a few yards of the drill, stop and park the tractor. 2. Crank the drill jack until the drill hitch matches the tractor drawbar height. 3. Continue backing the tractor until the drawbar and hitch are aligned. Stop and park the tractor. Adjust the drill-tongue height until you can install the hitch pin. 4. Install a hitch pin. Install a retaining clip to keep the pin from working out of the hitch. 5. Secure the drill safety chain to an anchor on the tractor capable of pulling the drill. 6. Connect the hydraulic hoses to the tractor remotes. 7. Move the jack to the stob on top of the drill tongue. Pin jack parallel with the tongue as shown in Figure 1-3. Great Plains Mfg., Inc. Bleeding the Hydraulics! WARNING! 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. To function properly, the hydraulics must be free of air. With air in the system, the hydraulics will move in jerky, uneven motions. If you install or replace a hydraulic component, follow these steps. 1. Check the fluid level in the tractor hydraulic reservoir. Bleeding the hydraulics with a low fluid level will draw air into the system. System capacity is 1/2 gallon. 2. Lower the openers to the ground. Unpin the ram end of the cylinder from the floating lug. Wire, block up, or otherwise safely support the cylinder so the rod will not contact anything when fully extended. See Figure Figure 1-3 Jack in Storage Figure 1-4 Cylinder Supported 3. Loosen the connection between the hose and rod-end cylinder fitting. 4. With the tractor idling, slowly work the tractor remote lever as if retracting the cylinder. Continue working the lever until oil seeps from the fitting. Tighten the hose connection. 5. Continue working the lever until the cylinder rod is completely retracted. 6. Loosen the connection between the hose and baseend fitting. 7. With the tractor idling, slowly work the tractor remote lever in the opposite direction as if extending the cylinder. Continue working the lever until oil seeps from the fitting. Tighten the hose connection. 8. Continue working the lever until the cylinder is completely extended. Repin the cylinder to the floating lug End-Wheel Drill M 11/7/02

16 Section 3 Adjustments Great Plains Mfg., Inc. Section 3 Adjustments This section covers basic field and maintenance adjustments. Before going to the field, you must set the seeding rate and adjust the seeding depth. Check the drive chains and disks scrapers periodically during the season. Seeding Adjustments Figure 3-2 Seed-Rate Handle Figure 1-1 Figure 3-1 Drive Sprockets 1. To adjust your seeding rate, first decide which drive type you need, 1,2,3 or 4, (see seeding chart). In order to change drive types, install the chain on the speed change box to desired setting, or install the chain over one of 4 different sprockets (figure 3-1) as follows: 1=72 tooth 2=34 tooth 3=23 tooth 4=14 tooth (See the owners manual for your drill.) Drive Type Notes: Drive Sprocket Speed Type Type 1 72-tooth Slowest Type 2 34-tooth Two Times Faster Than Type 1 Type 3 23-tooth Three Times Faster Than Type 1 Type 4 14-tooth Five Times Faster Than Type 1 Setting Seed-Rate Handle Position the handle shown in figure 3-2 to the setting indicated on the seed-rate charts. To adjust the handle, loosen the wing nut under the handle and slide until the indicator lines up with the correct setting. 2. There are many factors which will affect seeding rates: seed treatment, weight of the seed, size of the seed, surface conditions of the seed, tire configuration, tire pressure, and tire slippage. Minor adjustments will probably be needed to compensate for the above factors. NOTE: A pea-drive adaptor kit is available for the 1300 drill. Different seed-rate charts for peas and pinto beans are included in the kit. 3. The pounds-per-acre in the seed chart are based on 7.5 x 20 drill rib implement gauge wheel tires. 4. The large differences in seed size and treatment can cause a wide variation in actual seeding rates. The seed rate charts are based on average size seed. This may differ from the seed you are using. Use the seed rate chart as a starting point. Set the pounds-per-acre desired at the indicator number for your row spacing and complete the following procedures to calibrate the drill for your specific seed.! DANGER! 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. Checking Seeding Rate a. Place several pounds of seed over three of the feeder cups at the outboard end of the drill box. b. Disengage the lock-out hub on the drive wheel. c. Pull the seed tubes out of these three disk openers and place them into a container under the seed tubes to gather the seed while metering End-Wheel Drill M 11/7/02

17 Great Plains Mfg., Inc. Section 3 Adjustments d. Place the calibrator crank on the main jack shaft (figure 3-3) on the left hand side of the drill and turn it counterclockwise the number of turns noted below which would equal one acre. (Variances are due to total swath width.) This will be: Row spacings: 6 7 1/2 10 Rotations Check to be sure each cup has plenty of seed coming into it. Remember: Tire size and field conditions will also affect seeding rates. Be certain that your drill has the correct tires and that the tires are properly inflated. When drilling, check the amount of seed you are using by noting acres drilled, amount of seed added to drill, and level of seed in drill box. If you suspect that you are drilling more or less seed than desired, and you have accurately calibrated the drill to your seed, 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 is for wheat and other small grain seeds, the second handle position is for soybean and other large grain seeds. Should excessive cracking occur to the large seeds, drop the handle to the third position. The wide open position will allow complete clean out of the feed cup. MAKE SURE all handles are in the same position before drilling. (figure 3-5) Figure 3-3 Calibrator Crank e. Weigh the seed which has been metered. Divide by three. This will give you the ounces/pounds metered by each feeder 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 accordingly. 5. You may want to repeat the calibration procedure if the results of your calibration vary greatly from the suggested settings. Be sure to return calibrator crank to the storage position and secure with lock pin upon completion of calibration.

Refer to the fertilizer rate charts on page 23 to find sprocket sizes for your drill and desired meter rate. Driven Driver IMPORTANT: The fertilizer meter 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 the density conversion chart on page To switch between high and low range, loosen and slide the idler sprockets (1) out of the chain shown in Figure 3-2. Remove the chain. For high range, use the 16-tooth sprocket (2) and shorten the chain by removing the 13-pitch strand. For low range, use the 44-tooth sprocket (3) and lengthen the chain by installing the 13-pitch strand. Loosen set screw on jackshaft sprocket (4). Align sprockets and idlers. Retighten set screw. Re-install chain and move idlers into chain. Figure 3-6 Driver and Driven Sprockets Fertilizer Rate Calibration 1. Place several pounds of fertilizer over three of the fertilizer feed cups at the outboard end of the drill box. 2. Disengage the lock-out hub on the drive wheel. 3. Pull the fertilizer tubes out of these three disk openers and place them into a container under the fertilizer tubes to gather the fertilizer while metering Figure 3-5 Hi/Low Range Sprocket To change the driver-to-driven ratio, refer to Figure 3-3. Loosen and slide idler sprockets out of chain. Remove the lynch pins from the shafts and rearrange sprockets as necessary. Re-install chain and slide idlers into chain so chain has 1/4-inch slack. NOTE: Place the driver and driven sprockets next to the shaft bearings. Use the end of the shafts to store unused sprockets. Figure 3-7 Calibration Crank 4. Place the calibration crank (figure 3-7) on the main jack shaft on the left hand side of the drill and turn it counterclockwise the number of turns noted below which would equal one acre. (Variances are due to total swath width.) This will be: Row spacings: 6 7 1/2 10 Rotations Check to be sure each cup has plenty of fertilizer coming into it. 11/7/ End-Wheel Drill M 21
