12 706/1006NT 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 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. Refer to Figure 1 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.
14 706/1006NT 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. Refer to “Lubrication,” page 33. 4.
Preparation and Setup 15 Hitch Height Refer to Figure 3 1. For proper field operation, drill tongue should run level in field position. 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).
16 706/1006NT Hydraulic Hose Hookup Refer to Figure 6 Great Plains hydraulic hoses are color coded to help you hook up hoses to your tractor outlets. Hoses that go to the same remote valve are marked with the same color. Color Hydraulic Function Blue Transport Lift Cylinders To distinguish hoses on the same hydraulic circuit, refer to plastic hose holder. Hose under extended-cylinder symbol feeds cylinder base ends. Hose under retracted-cylinder symbol feeds cylinder rod ends.
Preparation and Setup 17 Bleeding 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.
18 706/1006NT 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 Refer to Figure 7 1.
Operating Instructions 19 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 ! WARNING Escaping fluid under pressure can have sufficient pressure to penetrate the skin. Check all hydraulic lines and fittings before applying pressure.
20 706/1006NT ! DANGER Watch your step when walking on drill ladder and walkboard. Falling from drill could cause severe injury or death. Field Operation ! DANGER 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 the seed rate book. 3.
Operating Instructions 21 Transporting ! WARNING Towing the drill at high speeds or with a vehicle that is Cylinder Lock not heavy enough could lead to loss of vehicle control. Loss of vehicle control could lead to serious road accidents, injury and death. To reduce the hazard, do not exceed 20 mph.

If ground is soft, place a board or plate under jack. 5. Extend jack until tongue weight is off tractor drawbar. Jack storage stob 6.
Adjustments 23 Adjustments Coulter Adjustments Refer to Figure 11 A no-till coulter (1) 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.
24 706/1006NT 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 1100 pounds for the 706 (550 pounds per side) and 1500 pounds for the 1006 (750 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.
Adjustments 25 Opener Adjustments Opener Down Pressure Refer to Figure 14 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.
26 706/1006NT Disk Scraper Adjustment Refer to Figure 16 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 and move scraper as needed.
Adjustments 27 Drive Train Operation Refer to Figure 19 Check all chain idlers at beginning of each season for proper adjustment. Check that each idler is taking up excess chain slack. The access door is located on the top side of the gage wheel arm near the pivot end. After first 100 hours of use and at beginning of each season, readjust idler sprocket in left wheel arm. To access idlers, remove access door.
28 706/1006NT Spring Tine Harrow Harrow Tine Angle Refer to Figure 21 The drawing on the right shows a successful harrow position for no-till and minimum-till conditions. Because of different soil moisture, trash levels and trash types, you may need to reposition the tube frame or tines. Initially position the frame and tines as shown, then readjust as necessary.
29 Troubleshooting Problem Cause Solution Uneven seed spacing or uneven stand Excessive field speed. Reduce field speed. Feed cups plugging. Clean out feed cups. Seed tubes plugging. Clean out seed tubes. Opener disks not turning freely. See “Opener disks not turning freely” in this Troubleshooting section. Opener not penetrating low spots. Adjust opener, page 25. Use faster drive type speed and close feed cup flutes to a more narrow position.
30 706/1006NT Problem Cause Solution Press wheels not compacting soil as desired Too wet or cloddy. Wait until drier weather or rework ground. Incorrect hitch height. Readjust hitch height, page 15. Press wheel depth does not match coulter depth. Readjust press wheel depth, page 25. Not enough down pressure on disk openers. Increase down pressure on openers, page 25. Grain box not emptying evenly Some models do not have same number of feed cups between each divider of bulkhead.
