4.6 WINGING DOWN 7‐PLEX TOOLBARS NOTE: Please ensure your case drain YELLOW banded hose(s) are connected to the tractor circuit which is plumbed directly to the reservoir first. If the control box has a 7‐ plex wing down button please use the following 2 steps to lower the wings safely. Ensure control box is powered up with 12v. Ensure the case drain(s) gauge on hydraulic block never exceeds 100 PSI, excessive amounts of pressure will damage the gauge. 1.
NOTE: In order to get the proper packing and penetrating forces per field, we recommend lowering the opener shank pressure from the tractor at the beginning of each field. Every new Seed Hawk toolbar manufactured leaves with the opener shank pressure set at approximately 1000 PSI. 5. Turing the min‐max “DOWN PRESSURE” dial allows the user to increase or decrease the desired packing pressure to achieve proper packing and penetration forces to seed. REFER TO SECTION 4.
4. Moving in a forward direction press the “ACK” button on the monitor, this will engage the opener shanks. REFER TO SECTION 4.5, pertaining to the control system being used. NOTE: The hydraulic down pressure applied to the opener shanks is controlled by a closed loop system that allows the operator to enter the desired operating down pressure. Entering the amount of down pressure the system should apply, can be done on the monitor as well.
NOTE: In order to get the proper packing and penetrating forces per field, we recommend lowering the opener shank pressure from the tractor at the beginning of each field. Every new Seed Hawk toolbar manufactured leaves with the opener shank pressure set at approximately 1000 PSI. The chain between the seed and fertilizer knife will be tight when applying the proper amount of pressure to the opener shank. Once the knives get tight, notice the shank pressure gauge and its reading.
4. Moving in a forward direction, turn “MASTER” switch to the on position, this will engage the opener shanks. Note section switches must be in SCT® in order for Sectional control® to work. REFER TO SECTION 4.5, pertaining to the control system being used. 5. Manually adjusting the packing pressure can be done by increasing or decreasing the packing pressure switch on the switch box.
4.11 PRIMARY OPERATION VARIABLES 4.11.1 PACKING Positive soil to seed contact is essential for optimum seed germination. Soil type, extent of tillage or disruption and moisture content all influence germination percentages. There are six primary variables that affect the quality of soil packing: Packer Tire Pressure Field Travel Speed Packing and Trip Pressure Mud Scraper Adjustment Cornering Furrow Depth and Width Knife Lateral Separation 4.11.
4.11.6 MUD SCRAPER ADJUSTMENT Ensure that the Pneumatic packer tire had a pressure of 10 to 15lbs. There is no adjustment to the Semi‐pneumatic since there is no air pressure. Also ensure the gap between the packer tire and the mud scraper is between the distances labeled in FIGURE 17. Be sure to check mud scraper setting before seeding and every year to ensure proper gap between packer tire and mud scraper. Gap 1/16” to 1/8” FIGURE 17 4.11.
4.11.8 FURROW DEPTH AND WIDTH The knives are designed to place fertilizer 0.75 in (19 mm) below and 1.5 in (38 mm) to the side of the seed. To adjust the depth of the fertilizer knife in relation to the seed knife: 1. Loosen hardware, #1 FIGURE 18. 2. Raise or lower fertilizer knife accordingly. NOTE: Factory setting for fertilizer knife is “Y”: 20.875 in (530 mm) from the carbide tip to the corner on the trip plate as shown in FIGURE 18. 3. Tighten hardware.
4.11.9 KNIFE LATERAL SEPARATION Confirm knife lateral separation, “Z” 1.5 in(38 mm), FIGURE 19, especially after replacing knives, to avoid seed damage when applying high rates of fertilizer. NOTE: As with any field adjustment procedure, make only one change to a variable, operate the implement for a short distance and observe whether the change made any difference and whether the difference was positive or negative in outcome. z FIGURE 19 4.12 SUPPLY AND DROP TUBES 4.12.

4.12.3 TWIN WING™ The Twin Wing™ Seed Opener Furrow Effect Picture as illustrated in FIGURE 23. FIGURE 23 Most Twin Wing™ openers are on 12” spacing. The customer would achieve 9” spacing due to the 3” seed separation (FIGURE 23, FIGURE 24 & FIGURE 25). With Single Side Band configuration 10” spacing is the narrowest spacing that Seed Hawk offers. What Twin Wing achieves is 2 rows of seed ¾” above and 1‐1/2” to both sides of the fertilizer band. The 1.
4.13 CROP RESIDUE CONSIDERATIONS Seeding into fields with heavy residue is challenging, but residue cover is essential to the success of a zero‐till cropping system. Ideally, the straw height from the previous year will be less than or equal to the width of the Seed Hawk Drill row spacing. For optimum results, the combine should chop the straw and spread the straw and chaff evenly across the entire swath width. The fertilizer and seed knives will catch and drag small amounts of crop residue while seeding.
4.14 SEED HAWK PACKER TIRE 1 3 2 8 5 7 6 4 Y1 Y2 X FIGURE 26 Item # 1 2 3 4 5 6 7 8 Y1 Y2 X Description Packer tire Fertilizer knife Seed knife Fertilizer Seed Original ground level Final packed surface Loose soil and straw 0.75 in (19 mm) 0.75 in (19 mm) 1.50 in (38 mm) The packer tire bulges slightly to provide uniform packing over the seed and fertilizer furrows. This leaves the seed 0.75 in (19 mm) below the curved path left by the packer wheel.
4.14.1 LOOSE SOIL CONDITIONS If the soil is too loose before seeding, the final packed surface will be excessively below the loose soil that is thrown to the sides. This increases the likelihood of soil falling, blowing or washing back into the packer tire path. The result is an altered seed depth. The solution to this is to ensure that the soil is not too loose before seeding. It may be necessary to pack the soil before seeding.
FIGURE 27 A bulging packer tire will cause the seed and fertilizer to be placed lower than the initial setting on the opener. One tip to know when a packer tire is low in air pressure is when it has less mud build up on it FIGURE 27.
4.15 SIDE BANDING W/ANHYDROUS AMMONIA WHILE SEEDING WARNING! Use extreme caution when applying anhydrous ammonia fertilizer. Inhalation, skin and/or eye contact, or skin penetration can cause serious health problems. Seek medical attention immediately if coming into contact with anhydrous ammonia. Extreme caution must be exercised when side banding with anhydrous ammonia (NH3). If the separation distance between the seed and the NH3 is not sufficient, the germinating seedling can be damaged.
4.16 DROP TUBE EXTENSION WITH NH3 The delivery drop tube should extend 0.5 in (13 mm) past the stainless steel clips. This usually prevents mud from freezing to the fertilizer knife. IMPORTANT: SEED HAWK ASSUMES NO RESPONSIBILITY IF SEEDLING DAMAGE IS CAUSED BY ANHYDROUS AMMONIA BURN. THE OPERATOR IS RESPONSIBLE FOR CHECKING AND SETTING THE SEEDER IN ALL FIELD CONDITIONS. 4.
5.0 LIQUID SYSTEM OPERATION 5.1 SYSTEM FLOW DESCRIPTION The metering pump, ground driven by the metering wheel, draws liquid fertilizer first through the flow valve, then the main filter. The liquid fertilizer is then pumped to the distribution system. A gauge indicates the operating pressure. Select the appropriate VR nozzle to adjust the liquid fertilizer delivery pressure.
6.0 SBR® HITCH TOOLBAR ONLY, LOUP III & SCT 6.1 REQUIREMENTS 1. Field must be seeded with G.P.S. auto steer and same row spacing the year before. 2. Must seed in exactly the same direction as the previous year. 3. The sensing arm must follow between the two rows of stubble 4”‐6” above the ground. 6.2 OPERATION NOTE: BEFORE OPERATION OF THE SBR, MAKE SURE THE TOOLBAR IS FOLDED DOWN IN WORKING POSITION. 1. Lower the SBR arm into field working position by removing locking pin shown in FIGURE 28.
7.0 MAINTENANCE 7.1 HYDRAULIC CARTRIDGES Hydraulic cartridges, FIGURE 29, which is located on hydraulic block, should only be removed, inspected and cleaned at the end of each seeding season if problems occur with them. Some cartridges may be disassembled for additional access for cleaning. It is recommended that the disassembly and further cleaning of this type of cartridge be performed by a technician trained in hydraulic component servicing. FIGURE 29 7.
7.3 CASTER WHEEL GREASE FITTINGS Lubricate 2 grease fittings, #1 FIGURE 31, DAILY. NOTE: Two fittings are on top and the other is on the bottom of the caster wheel plate. 7.4 CASTER WHEEL PLATE GAP Measure gap between caster wheel plates and tighten castle nut every 100 hrs. The gap, “X”, should not exceed 1/8” (3 mm), FIGURE 31. Adjust gap, if necessary, by tightening castle nut on top of caster wheel plate assembly.
