12 1205NT Introduction Great Plains welcomes you to its growing family of new product owners. This drill 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.
Introduction 13 Using This Manual This manual will familiarize you with safety, assembly, operation, adjustments, troubleshooting and maintenance. Read this manual and follow the recommendations to help ensure safe and efficient operation. The information in this manual is current at printing. Some parts may change to assure top performance. Definitions The following terms are used throughout this manual.
14 1205NT Owner Assistance If you need customer service or repair parts, contact a Great Plains dealer. They have trained personnel, repair parts and equipment specially designed for Great Plains products. Your machine’s parts were specially designed and should only be replaced with Great Plains parts. Always use the serial and model number when ordering parts from your Great Plains dealer. The serial-number plate is located as shown in Figure 1.
Preparation and Setup 15 Preparation and Setup This section will help you prepare your tractor and drill for use. Before going to the field, you must hitch a tractor to the drill, hook up hydraulics and check that hydraulics have been bled. Prestart Checklist 1. Read and understand “Important Safety Information,” page 1. 2. 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.
16 1205NT Hitch Height 1. For proper field operation, drill tongue should run level in field position. See Figure 3. a. With drill in field position, adjust tongue jack to level tongue. b. Measure tractor drawbar height to determine proper hitch height on drill. c. Attach hitch to tongue with two 3/4 x 6 inch bolts (1), lock washers (2) and nuts (3). NOTE: Mounting holes in drill hitch are offset so hitch can be turned over and attached in three different positions, giving six different hitch heights.
Preparation and Setup 17 Hydraulic Hose Hookup High Pressure Fluid Hazard: Only trained personnel should work on system hydraulics! 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.
18 1205NT Rephasing Cylinders The lift cylinders may, after a period of time, get out of time or phase. The effects of this can be seen when one side of the drill is running too low or too high because its lift cylinder is either over extended or not retracted compared to the other lift cylinder. To rephase the cylinders, raise drill completely and hold tractor hydraulic lever on for a few seconds to give cylinders time to rephase.
Preparation and Setup 19 Bleeding Hydraulics High Pressure Fluid Hazard: 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.
20 1205NT 6. Repin cylinders to drill frame and gauge wheel arm with transport cylinder locks in place. If any air still is trapped in either cylinder, the cylinder will have a spongy, erratic movement and drill will not raise evenly. If necessary, repeat bleeding process. 7. Refill tractor hydraulic fluid reservoir to its proper level. NOTE: After the drill is raised, a slight settling will occur due to the action of the rephasing cylinders. Leveling Drill See Figure 8. 1.
Operating Instructions 21 Operating Instructions This section covers general operating procedures. Experience, machine familiarity and the following information will lead to efficient operation and good working habits. Always operate farm machinery with safety in mind. Prestart Checklist High Pressure Fluid Hazard: Escaping fluid under pressure can have sufficient pressure to penetrate the skin. Check all hydraulic lines and fittings before applying pressure.
22 1205NT Mis-step Hazard: Watch your step when walking on drill ladder and walkboard. Falling from drill could cause severe injury or death. Field Operation Crushing Hazard: You may be severely injured or killed by being crushed between the tractor and drill. Do not stand or place any part of your body between drill and moving tractor. Stop tractor engine and set park brake before installing pins. 1. Hitch drill to a suitable tractor. 2. Set seed population as explained in “Seeding Rate”, page 29. 3.
Operating Instructions 23 Marker Operation Optional marker attachments are available from your Great Plains dealer. Before operating markers, make sure hydraulics are properly bled as described under “Marker Adjustments”, page 38. Dual markers equipped with a sequence valve are powered off the same hydraulic circuit. The markers cycle in the following sequence: 1. 2. 3. 4. right up, left up right down, left up right up, left up right up, left down You can adjust marker folding speed.
24 1205NT Unload drill box. The drill can be transported with a full box of grain, but the added weight will increase stopping distance and decrease maneuverability. Unload drill box before transporting if at all possible. Clearance. Remember that the drill is wider that the tractor. Allow safe clearance. Road rules. Comply with all federal, state and local safety laws when traveling on public roads. Lock-out Hub.
Adjustments 25 Adjustments Coulter Adjustments A no-till coulter (1), Figure 13, is mounted directly ahead of each opener on the drill. The coulters cut through heavy trash and make a groove in the soil for the openers. The coulters are mounted on the drill frame so coulter cutting depth changes as the drill is raised and lowered. To set drill seeding depth, you must: 1. Set coulter depth with hydraulic stop. 2. Set opener depth with T-handles on press wheels. 3.
26 1205NT Coulter Down Pressure Weights. If more weight is required for your soil conditions, add weights to weight brackets located on box frame. No more than 1200 pounds (600 pounds per side) should ever be added. Add an equal amount of weight to each end of drill. See Table 1. Pounds Per Coulter 7 inch 7.5 inch 8 inch 10 inch Empty Drill 274 282 290 363 Drill with 300 pounds added 304 314 323 406 Drill with 600 pounds added 334 345 356 449 Table 1 Weight Chart Spring Length.
Adjustments 27 Opener Adjustments Opener Down Pressure Opener springs provide the down pressure necessary for opener disks to open a seed trench. The springs allow the openers to float down into depressions and up over obstructions. Each opener spring can be adjusted for down pressure. This is useful when penetrating hard soil and for planting in tractor tire tracks. To adjust the pressure, remove “W” clip at bottom of spring.
28 1205NT Disk Scraper Adjustment To keep opener disks turning freely, dirt scrapers are mounted between disks to clean as the disks rotate. As field conditions vary, scrapers may need to be adjusted. In damp conditions, scrapers may need to be lowered. If openers are not turning freely, scrapers may need to be raised. Scraper bolt To adjust scrapers, loosen 3/8 inch bolt shown in Figure 18 and move scraper as needed.
Adjustments 29 Seeding Rate Calibrating the seeding rate requires four steps: 1. selecting one of four drive types, 2. setting the seed-rate handle, 3. positioning the feed-cup door, and 4. checking the seed rate. Refer to the seed rate charts beginning on page 31. These charts list the proper drive type 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 295/75/R22.
30 1205NT Position Feed-Cup Doors See Figure 22. For wheat and other small seeds, move feed cup door handles to highest position. For soybeans and other large seeds, lower handles to second position. If excessive seed cracking occurs, lower handles to third position. Move handles to fourth, wide-open position, for seed cup clean out. Make sure all handles are in same position before drilling.

36 1205NT Fertilizer Meter Rate Fertilizer application rates will vary with fertilizer type, density and particle size. Relative humidity and field conditions can also affect application rates. The chart on page 37 is based on material with a density of 65 pounds per cubic foot (1.04 kg/ L) and average particle size. Initially set rate according to the charts, then calibrate the drill to your material as described below.
Adjustments 37 1. When drilling, check the rate by noting acres drilled, amount of fertilizer added to the drill and level of material in drill box. If you are applying more or less that desired, adjust the metering rate slightly to compensate for field conditions. Fertilizer Rate Chart (pounds per acre) Row Spacing Setting number 6" 7" 7.
38 1205NT Marker Adjustments Bleeding Marker Hydraulics The markers must be properly bled to displace air in the hydraulic system and for the sequence valve to work properly. Failure to do so could cause marker to drop quickly and cause damage to marker voiding the warranty. Overhead and Crushing Hazard: Keep others away when folding or unfolding markers. Markers may fall quickly and unexpectedly if hydraulics fail.
