OPERATION FIELD OPERATION OPERATOR RESPONSIBILITY It is the responsibility of the owner to ensure SAFE operation, adjustment, maintenance and repair of the Seed Hawk Drill. This responsibility includes the proper training of any person who will operate, adjust maintain, repair or work in the vicinity of the Seed Hawk Drill. This Operator’s Manual provides step-by-step procedures for proper operation, field adjustment, routine maintenance and equipment repairs for the Seed Hawk£ Drill.
OPERATION TRACTOR HOOK UP Change the tractor’s hydraulic filter after the first day or two of Seed Hawk operation. Some debris may have collected in the hydraulic system during manufacturing. Changing the filter will remove this debris, and prevent it from damaging components on the seeder and tractor. Shank lift and lower (Two hoses with red bands) Connect the pair of 1/2” hydraulic lines to activate the shank lift and lower.
OPERATION Case Drain(s) (One hose with yellow band) You must also connect the case drain line (yellow band) to return hydraulic fluid back to the tractor reservoir. The case drain line is a 1/2” (13 mm) line from the hydraulic manifold. The case drain line(s) MUST return to the tractor UNRESTRICTED.. Failure to do so can cause damage to the hydraulic cylinders or fan motor and will void Manufacturer’s Warranty. (Note: Do not plug this line for storage; damage to the gauges and manifold may occur.
OPERATION HYDRAULIC HOSE HOOK UP These red banded hoses are for your shank lift and lower. One hose has a ball valve to close for transport and opened while seeding. These green banded hoses are for your wing lift and lower. When the wings are on the ground, the lever in the cab is locked in the forward position while seeding. This pressurizes the hydraulic manifold in order to use the Seed Hawk Tool Bar successfully.
OPERATION Hydraulic Manifold Description This picture is a Hydraulic manifold. The large shank pressure gauge is in front of the tow between air cart. Normally the gauge is left of the wing down pressure gauge. This is the packing and penetration motor. Your shank pressure switch in the cab controls the motor. This is the wing down pressure gauge. It is preset for your width of machine. It will show this preset pressure while seeding.
OPERATION PRE-OPERATION CHECKLIST Inspect tires. Check tire inflation pressure and adjust, if necessary. Inspect wheel hub fasteners. Adjust torque to proper setting, if necessary. NOTE: Check wheel hub fasteners periodically to ensure proper tightness, especially prior to travel on public highways. Ensure flow valve (liquid fertilizer tank), if equipped, is closed. Check depth setting of packer wheel arms. Adjust, if necessary. Check depth setting of fertilizer knives. Adjust if necessary.
OPERATION Winging the machine down NOTE: If your Seed Hawk control box in the cab of the tractor does not have a wing down button, please disregard this page and lower your wings down with the tractor circuit. Please ensure your return line is coupled first. If your control box has a wing down button please use the following 3 steps to lower your wings safely. 1. First ensure the Seed Hawk box’s power is turned on. 2.
Step # 1 Turn the MAIN POWER switch on. Step # 2 Take a look at your tractor hydraulic levers. Step # 3 Lock on your tractor lever that your green banded hoses are connected to. You will see full tractor pressure on the bottom middle gauge of your hydraulic manifold. Step # 4 While moving forward with your tractor, engage your tractor lever that your red banded hoses are connected to. Locking this lever on for long periods of time will lead to o-ring failure in your hydraulic block on your seeder.
NOTE: (The chain that is between the seed and fertilizer knife is tight). Every new Seed Hawk that is manufactured leaves with its shank pressure set at approximately 900 PSI. Step # 7 In order to get the proper packing and penetrating forces per field, we recommend that you lower your shank pressure from the cab at the beginning of each field. Note: All of the fertilizer knives will decrease in penetration pressure. Dial the shank pressure down.
Step # 9 Once the knives get tight , notice the shank pressure gauge and its reading. In good seeding conditions, add an additional 200 PSI to the system. When seeding small seeds such as canola in wet conditions, adding the additional 200 PSI is not recommended. You would tend to over pack. NOTE: The chain that is between the seed and fertilizer knife is tight You now know that you are applying the proper amount of pressure for the current field.
OPERATION Primary Operation Variables PACKING Positive soil to seed contact is essential for optimum seed germination.
OPERATION Packing and Trip Pressure Tips: x It may be desirable to further increase packing and trip pressure in drier, sandier soils. x Higher packing and trip pressures can result in more rocks being pulled out of the soil. x Higher wear on opener parts may be experienced with higher pressure. x Soil packing will be more firm with higher packing and trip pressure. x A reduction in shank tripping action will be experienced in firmer soil conditions.
OPERATION Cornering Ideally, the most effective seeding, fertilizer banding and soil packing occurs when the implement is pulled in a straight line. Some field conditions will not allow all of the seeding to occur in a straight line. It is important to remember that as the packer tire is following a curved path, it will tend to ride up on one side of the furrow. Seed and fertilizer placement, as well as, packing performance are all compromised.
OPERATION Knife Lateral Separation Confirm knife lateral separation, “Z” 1.5 in (38 mm), FIG. 15, 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 FIG.
OPERATION RANGE OF KNIFE CONFIGURATIONS 1 2 3 FIG. 17 The Seed Hawk fertilizer knife allows a variety of product delivery configurations: 1. 2. 3. 4. 5. Seed knife Liquid fertilizer Granular fertilizer Dry and Liquid or NH3 fertilizer Double Extrusion (next page) a. The Double Extrusion drop tube may be used for applying granular and Liquid Fertilizer or NH3 behind the granular product. Call your dealer for further information.
OPERATION The New Twin Wing Seed Opener Furrow Effect Picture as illustrated in Fig.18 Fig.18 Most Twin Wing openers are on 12” spacing. The customer would achieve 9” spacing due to the 3” seed separation ( Fig 18 & 19). Normally 10” spacing is the narrowest spacing that Seed Hawk offers. What this knife essentially achieves is an additional seed row on the other side of the band of fertilizer which has been placed by the fertilizer knife in front of the seed knife. The 1.
OPERATION This double drop tube (Fig. 20) can be used when applying starter liquid phosphate blend down in the seed row. I may also be used on the fertilizer knife when seeding peas through the fertilizer knife and applying a liquid starter phosphate blend with the peas. This option is not a standard option. Contact your dealer for more information. Fig.
OPERATION SEED HAWK PACKER TIRE 1 3 2 8 5 7 4 Y1 Y2 X FIG. 21 1 2 3 4 5 6 7 8 Y1 Y2 X 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.
OPERATION 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.
OPERATION SIDE BANDING WITH 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 heath problems. Seek medical attention immediately if coming into contact with anhydrous ammonia. A bulging packer tire will cause the seed and fertilizer to be placed lower than the initial setting on the opener.
OPERATION 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. Several factors affect how far from the point of injection in the soil NH3 will move: x x x x x NH3 will move farther is dry soils than wet soils. Hilltops tend to have lower soil moisture content and are therefore more susceptible to NH3 travel. NH3 will move farther in light textured soils (e.g.
OPERATION DROP TUBE EXTENSION with NH3 The delivery drop tube should extend 0.5 in (13 mm) past the stainless steel clips. This will prevent 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. PLACING PHOSPHATE FERTILIZER WITH SEED IMPORTANT: Seed Hawk does not recommend placing phosphate fertilizer directly with the seed.
SPECIFICATIONS and OPERATION OF SBR HITCH Requirements: - must be seeded with G.P.S.
REAR WHEEL STEERING Rear wheel steering provides a number of functions which increase field seeding consistencies. Below it describes all the mechanical aspects of the steering components. Some benefits of rear wheel steering are: x Minimizing skewing on side hills. x Maintaining row spacing when cornering The Steering sensor arm is located on the second rank and is also pressured down to minimize skipping. The sensor arm triggers electrically left of right through either switch on the rear axle.
MAINTENANCE HYDRAULIC CARTRIDGES Hydraulic cartridges, FIG. 22, should be removed, inspected and cleaned at the end of each seeding season. 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. FIG. 22 HYDRAULIC CYLINDERS Inspect hydraulic cylinder seals and hose connections at cylinder fittings every 10 hrs or daily.
