Great Plains Manufacturing, Inc. Preparation and Setup 13 Preparation and Setup This section helps you prepare your tractor and drill for use.
14 1007NT Great Plains Manufacturing, Inc. Hitching Tractor to Drill In lowered (field) position, with the drill frame set at the desired height via depth control valve (see page 29), the tongue must be level. When hitching for the first time: • it is necessary to adjust hitch height (page 74), and 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.
Preparation and Setup Great Plains Manufacturing, Inc. 15 Hydraulic Hose Hookup Connect hydraulic system to tractor before lifting the drill. 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.
16 1007NT Great Plains Manufacturing, Inc. Electrical Connection Refer to Figure 6 (which depicts both European and North American style connectors - if your implement does not have the correct connector for your tractor, contact your Great Plains dealer) 13. Plug the drill lighting connector into tractor outlet. 14. Coil-up and tie-up excess cable, allowing enough slack for turns and ridges.
Great Plains Manufacturing, Inc. Operating Instructions 17 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. Pre-Start Checklist Escaping fluid under pressure can have sufficient pressure to penetrate the skin. Check all hydraulic lines and fittings before applying pressure.
18 1007NT Great Plains Manufacturing, Inc. Drill Lift/Lower Raising and lowering the drill relies on one front cylinder, and one rear lift-assist cylinder. Both cylinders are on the same circuit and operate in unison, although at different rates front to back. When lowered, the rear lift-assist arms raise more rapidly than the front rockshaft, resulting in the rear caster wheels being off the ground during planting. The rear wheels play no role in setting planting depth.
Operating Instructions Great Plains Manufacturing, Inc. 19 Caster Pivot Locks Refer to Figure 9 To prevent side movement of the drill when transported by trailer, the lift-assist casters may be locked in their fullreversing orientation. A spring-loaded pin 1 engages a cutout 2 in the caster pivot plate, preventing rotation. Use this feature only for trailer transport. Do not use these locks for towing drill on own wheels or field operations.
20 1007NT Great Plains Manufacturing, Inc. Transporting The drill may be transported on its own wheels, or on a trailer. Transport on Drill Wheels Before transporting with a tractor, check these items: 1. Check that tractor is sufficient for towing the drill. Tractor must have at least 80 horsepower (60 kW). Use a tractor with adequate weight relative to drill. See the tables below for typical drill weights. 2. Unload drill boxes.
Great Plains Manufacturing, Inc. Operating Instructions 21 For Any Transport Keep Clearance in Mind Remember that the drill may be wider than the tractor. Allow safe clearance. Observe Road Rules Comply with all national, regional and local safety laws when traveling on public roads. Trailer Transport Loading Trailer 1. Hitch raised and locked drill to suitable tractor. 2. Carefully line-up the tractor, drill and trailer, so that: a. no turns are needed for the final movement, and b.
22 1007NT Great Plains Manufacturing, Inc. Loading Materials Fully loaded with dense seed and fertilizer, the drill weighs an additional 1970 lbs (894 kg). Include this weight when checking tractor capability. 3 2 1 The drill must be hitched for seed loading. Load slightly more material than needed, because consumption rates can vary between compartments even though the furrow rates are identical. 1 Main Seed Box Loading 1.
Operating Instructions Great Plains Manufacturing, Inc. 23 Unused Boxes Unless steps are taken, all meter shafts of all boxes are operating whenever the drill is lowered and moving. To prevent needless wear, disable any unneeded ground drive or box(es). 1 Ground Drive Lock-Up On a drill with Native Grass, both left and right ground drives will be operating unless one is disengaged.
24 1007NT Great Plains Manufacturing, Inc. Material Rates Overview Details of seed and fertilizer rate setting are found in the Seed Rate Manual, and rely on data from that manual. Rate setting controls are different for each box, but independent for each box. Some boxes have more than one control.
Operating Instructions Great Plains Manufacturing, Inc. 25 Acremeter Operation The acremeter counts shaft rotations whenever the shaft is rotating - this is with the drill lowered and in motion or during crank operation. The meter is programmed to display rotations as acres or hectares, when using all rows, factory-specified tires and tire inflations. Note: Unusual conditions and/or non-standard row spacings can cause the acremeter tally to vary from actual acres planted.
26 1007NT Great Plains Manufacturing, Inc. Field Operation 1. Hitch drill to a suitable tractor (page 14). Check depth and level (page 14). 2. Fully raise drill (page 18). 3. Rotate ground drive wheel. Check that feed cups, seed tubes and drives are working properly and free from foreign material. 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.
Adjustments Great Plains Manufacturing, Inc. 27 Adjustments To get full performance from your drill, you need an understanding of all component operations, and many provide adjustments for optimal field results. The 1007NT has double-disc 07 Series openers with depth-controlling press wheels mounted on floating opener frames. Opener bodies are staggered for easy soil flow. All openers pivot on a common axis to maintain consistent depth as the opener frame follows contours.
28 1007NT Great Plains Manufacturing, Inc. Coulter Adjustments Refer to Figure 15 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 group coulter depth by raising or lowering the front rockshaft with the depth control valve (next topic). 2.
Adjustments Great Plains Manufacturing, Inc. 29 Coulter Depth (All Rows) Refer to Figure 16 Group coulter depth is controlled by the height at which a depth control valve 1 stops retraction of the front (rockshaft) cylinders. Further adjustment is available at the front lift cylinder eyebolt. Falling Frame Hazard: Make adjustments with drill lowered, or locked up. Making adjustments with drill partially raised can result in sudden downward movement of frame, with risk of serious injury.
30 1007NT Great Plains Manufacturing, Inc. Front Eyebolt Adjustment Refer to Figure 18 6. Raise drill and install lock channels. Loosen jam nut 5. 7. Adjust stop nut 6 to raise eyebolt. The depth change per unit of eyebolt movement is 1.75in depth per inch of eyebolt, or 4.4 cm depth per cm of eyebolt. This is also about 3⁄16in (5mm) of depth change per turn of the adjust nut. 8. Re-tighten jam nut when desired depth is achieved. 9.
Adjustments Great Plains Manufacturing, Inc. 31 Coulter Spring Length Coulter springs are preset at 10in (25.4cm), giving coulters an initial operating force of 400 pounds before the spring compresses. This setting is adequate for many difficult no-till conditions. 1 In normal operation at target running depth, springs are at full extension or only slightly compressed. They compress briefly at obstructions and in denser soil.
32 1007NT Great Plains Manufacturing, Inc. Coulter Depth (Individual Rows) The running depth of all coulters is adjusted simultaneously by changing the tool bar height. Adjusting the height of a small number of coulters may be useful for rows in tire tracks. 3 2 Adjust individual coulters as follows. 1. On level ground, lower the drill until coulters just touch the ground. 2. Raise the drill by the extra amount you need to lower the rows in tracks. 1 Refer to Figure 20 3.
Adjustments Great Plains Manufacturing, Inc. 33 Calibration Overview Detailed calibration steps vary with each box. Details are found in the Seed Rate Manual. 1 Some general information applies to all boxes. Calibrate with Drill Raised Perform the calibration with the drill hitched and raised. Install cylinder locks. Calibrate for 1/10th Acre or Hectare 2 The number of revolutions per area is: Area Sampled Full Acre 1/10th Acre Full Hectare 1/10th Hectare Wheel Revolutions 491.6 49.2 1214.8 121.
34 1007NT Great Plains Manufacturing, Inc. Row Unit Adjustments Refer to Figure 23 (which depicts an 07 series row unit fully populated with all optional accessories [except Fertilizer and Seed-Lok] supported for use with the 1007NT drill; coulter is not part of opener assembly and is not shown) From front to back, a Great Plains 07 Series row unit can include the following capabilities (some optional): 2 6 8 3 9 1.
Adjustments Great Plains Manufacturing, Inc. 35 Disc Blade Adjustments Opener disc angle and stagger is not adjustable, but disc-to-disc spacing is, and may need attention as discs experience normal wear. Spacers must be reset when blades are replaced. Refer to Figure 24 The ideal spacing causes the blades to be in contact for about one inch. If you insert two pieces of paper between the blades, the gap between them should be 0 to 1.75in (0-4.4cm).
36 1007NT Great Plains Manufacturing, Inc. Opener Adjustments “W” Opener Down Pressure Opener springs provide the down pressure necessary for opener discs 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 planting in tractor tire tracks. Refer to Figure 26 To adjust the pressure, remove “W” clip at bottom of spring.
Adjustments Great Plains Manufacturing, Inc. 37 Seed-Lok™ Lock-Up Optional Seed-Lok firming wheels provide additional seed-to-soil contact. The wheels are spring loaded and do not require adjusting. In some wet and sticky conditions the wheels may accumulate soil. To avoid problems associated with this, you can lock-up the firmers. Refer to Figure 28 (shown with an opener disc removed for clarity - this task can be performed with discs mounted) To lock up Seed-Lock wheels: 1. Pull catch wire aside 1 2.
38 1007NT Great Plains Manufacturing, Inc. Troubleshooting Problem Uneven seed spacing or uneven stand Uneven seed depth Opener discs not turning freely Actual material rate different than desired Excessive seed cracking 150-290M Cause Solution Excessive field speed. Reduce field speed. Feed cups plugging. Clean out feed cups. Seed tubes plugging. Clean out seed tubes. Opener discs not turning freely. See “Opener discs not turning freely” in this Troubleshooting section.
Troubleshooting Great Plains Manufacturing, Inc. Problem Cause Too wet or cloddy. Press wheels not compacting soil as desired Press wheel depth does not match coulter depth. Not enough down pressure on disc openers. 39 Solution Wait until drier weather or rework ground. Readjust press wheel depth, page 37. Increase down pressure on openers, page 36. Boxes not emptying evenly Some boxes do not have same num- Load more material than required.
40 1007NT Problem Acremeter inaccurate 150-290M Great Plains Manufacturing, Inc. Cause Solution Excess wheel slippage Check frame height. If correct, solution may be to wait for drier conditions. Passes misaligned. Check that planting passes are not leaving gaps (under-reporting area) or causing overlap (over-reporting area). Wheel slippage is varying from nominal. If variance is consistent, develop a correction factor for your conditions. Check that acremeter is for your drill.
Maintenance and Lubrication Great Plains Manufacturing, Inc. 41 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. OFF You may be severely injured or killed by being crushed under the falling implement.
42 1007NT Great Plains Manufacturing, Inc. Materials Clean-Out Main Box Clean-Out Refer to Figure 30, which depicts the seed cup door handle in a normal operating position. 1. Set the Seed Rate Handle to zero (0). This moves the seed cup sprockets out of the seed path. 1 2. Position a tarp or bucket under each row or set of rows to be cleaned out. 3. At the seed cup for that row, pull the door handle 1 out of the operating detent range, and swing it down to position 2 . 4.
Great Plains Manufacturing, Inc. Maintenance and Lubrication 43 Small Seeds Box Clean-Out 1. Open lid of each box and scoop out as much seed as possible. 2. To recover remaining seed, place a collection tarp under the small seeds tubes at the openers. 3. Raise drill. 4. Set seed rate handle to 100. 5. At left gearbox, rotate calibration crank or ground drive wheel until no seed flows. 6. If a vacuum cleaner is available, remove any residual seed from top of meters.
44 1007NT Great Plains Manufacturing, Inc. Leveling Drill This operation requires a tape measure. 1. Move drill to level hard ground, ideally a paved surface or concrete pad. Accurate measurement for side-to-side level will be difficult on open soil. 2. Set/check eyebolts.
Great Plains Manufacturing, Inc. Maintenance and Lubrication 45 Disc Maintenance Coulter and opener disc blades wear in normal service, becoming smaller in diameter. Periodically check blade diameter, and replace when below the recommended limits. Discs can also be dented by unusual field hazards, or bent. Replace damaged blades immediately. Opener Disc Replacement Replace 15in (38.
46 1007NT Great Plains Manufacturing, Inc. Chain Maintenance Inspect and lubricate chains regularly. The slack of new chains tends to increase during the first few hours of operation due to seating. 1 All chains are #40 roller chains. 2 Chain Slack Check slack within the first 8 hours of operation and tighten idlers as necessary. Refer to Figure 33, which, for clarity, greatly exaggerates slack, and omits the idlers. 1.
