OPERATION FILL AUGER – 10 inch FIG 1 DANGER! ELECTROCUTION HAZARD. Use extreme caution when moving the auger, especially near power lines. It is not necessary to come into direct contact with an overhead power line for electrocution to occur. Serious injury or death will result WARNING! ENTANGLEMENT HAZARD. Keep arms, hands and legs away from auger intake. Wear appropriate fitting clothing when working in the vicinity of an auger.
OPERATION POSITIONING THE AUGER 1. Ensure that the area in the vicinity of auger operation is free of obstructions and that all bystanders, especially children, are kept at a safe distance before positioning or operating the auger. 2. Unfold auger and position it where filling and emptying the tank is optimal. 1 FIG 1. 1 FIG. 1 3. Lock the auger arm into position so auger will not move if positioned on unlevel ground 1 FIG. 2. 4. Allow hopper to come into contact with the ground before final positioning.
OPERATION 3. If circuit is already engaged direct the fan diverter valve to the fill auger position from the fan location. 1 FIG 4. 1 FIG. 4 4. The handle on the auger tube is to operate the auger flighting in a forward or reverse motion. 1 FIG 5. 1 FIG. 5 AUGER POSITION FOR UNLOADING AIR TANK 1. FIG. 6 Unlock the second auger arm to allow the auger tube to pivot under either of the tank compartments in order to empty them. 1. FIG 6.
OPERATION AUGER TRANSPORT POSITION IMPORTANT: Fill auger should always be secured for transport, no matter how short the distance. 1. Position the auger so that the tube is resting on the locking mechanism at the back of the tank and the discharge spout is hanging freely. 1 FIG 7. 1 FIG. 7 2. The locking mechanism must be use when transporting at all times. 1 FIG 8. 1 FIG. 8 NOTE: It is easier to move the auger when on level ground. . 2. Push the auger diverter valve back to the fan position. FIG 9.
OPERATION Fan(s) (optional) (Two hoses with blue bands) Connect the pair of 3/4” hydraulic lines to supply the hydraulically driven fan motor. The pressure line is marked with a narrow blue band, and the return line is marked with a wide blue band. This tractor lever is locked in full pressure position while seeding. Case Drain(s) (Two hoses with yellow bands) You must also connect the case drain lines (yellow bands) to return hydraulic fluid back to the tractor reservoir.
OPERATION Metering Roller The metering roller provided in each compartment is designed to accommodate every / all product for seeding small oil seeds to large pulses as well as granular fertilizer. There are sections that make up the roller which can be replaced if damage occurs. There are two colored roller sections on some meters. The red sections have an 11% less displacement than the black sections.
OPERATION SEEDHAWK PRESSURIZED METERING SYSTEM FAN(S) Some models are configured with a single fan while others may be configured with dual fans. Fans are driven by hydraulic motors with speed controlled by the tractor hydraulic flow control system. Fan speed is indicated on the monitor panel in the cab. Set fan speed to effectively transport the seed. A reminder that higher fan speeds will increase seed bounce and possibly damage the seed. Higher fan speeds also require more power input from the tractor.
OPERATION CHECKING AIR AND PRODUCT FLOW The test procedure outlined below serves as a guideline for ensuring proper fan speed for effective delivery of product: 1. Remove hose(s) from an outside opener and temporarily attach to the frame of the seeder with the hose looping no more than 12 in (300 mm) below the frame. 2. Begin seeding at normal field speed and observe distance product discharges from hose(s) attached to the frame.
OPERATION NOTE: In the case of a single fan configuration used to double-shoot product, follow the above procedure and adjust the position of the air damper, 1, FIG. 46, to set an effective air flow for each product. IMPORTANT: DO NOT set fan speed above 5000 rev/min. Excessive fan speed will damage the fan drive motor and requires more power from the tractor hydraulic system. GROUND DRIVE METERING The ground drive metering system is engaged by activating an electric clutch, 1 FIG. 34.
CALIBRATION There is a funnel provided that hangs on the bottom of the meter you are calibrating. First take off the bottom plate of the meter and slide on the funnel. Set the Seed Hawk pail under the funnel to catch your product. FIG 4. NOTE: Prime your roller before proceeding to turn the crank handle to meter out product. NOTE: When weighing your pail with product, ensure the pail is zeroed out prior to metering product.
CALIBRATION Here in Fig 1 & 2 are some pictures showing where the setting for 37 is on the Vaderstad Gearbox from the calibration example. Ensure the half width shut offs are set for small or large seed settings prior to priming the roller. FIG 1 1 FIG 2 FIG 3 2 3 Another look at the Vaderstad gearboxes. NOTE: Ensure the input shaft pins on the gearbox or gearboxes are taken out while calibrating one compartment at a time.
CALIBRATION This illustration shows the diverter valve in the calibration position and the lower air stream position. The product flows under the roller and the diverter valve diverts the product into the lower airstream. This illustration shows the diverter valve in the up position. The product flows under the roller and is diverted into the top airstream.

LIQUID SYSTEM OPERATION 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 size orifice to adjust the liquid fertilizer delivery pressure.
LIQUID SYSTEM OPERATION FILLING THE LIQUID FERTILIZER TANK To fill the liquid fertilizer tank: 3 2 1. Remove fill cap, 1 FIG. 40, and attach fill hose from liquid fertilizer supply source to the quick coupler. 2. Open fill valve, 2 FIG. 40 and begin filling tank by starting fill pump. 1 3. When tank is near full, shut off fill pump and close main valve, 3, FIG. 40. FIG. 41 A closer picture of fill plumbing. FIG.40 FIG.
LIQUID SYSTEM OPERATION CHECKING FERTILIZER RUNS Perform the following test to ensure that each fertilizer run is functioning properly: 1. Ensure that tank is at least partially filled with either water or liquid fertilizer. 2. Lower metering wheel and proceed forward about 20 - 30 ft (6 - 9 m). 3. Stop tractor and look at ground behind each opener to ensure liquid fertilizer is discharged behind each run. APPLYING FERTIILIZER LIQUID To apply liquid fertilizer, ensure that main flow valve, 1 FIG.
LIQUID SYSTEM OPERATION AGITATE LIQUID FERTILIZER It is recommended that the contents in the liquid fertilizer tank be agitated for a few minutes before seeding if liquid fertilizer in the tank has sat for more than eight hours. NOTE: Phosphate is heavier than other nutrients and will tend to settle to the bottom of the tank. 2 To agitate tank contents: 1. Remove fill cap, 1 FIG. 43. 2. Attach suction line of fill pump to quick coupler at the bottom of the tank. 3.
LIQUID SYSTEM OPERATION A liquid fill pump is an option when the liquid onboard tank is ordered. It is usually located at the rear of the liquid tank. Example of a double orifice liquid Kit. One row of orifices are #49’s and the other orifices are #30’s. The grower can open either, or both, at any time. The grower would change the orifice selection to maintain system pressure. 30-35psi is an optimal pressure for this liquid system.
LIQUID SYSTEM CALIBRATION LIQUID FERTILIZER APPLICATION RATES JOHN BLUE£ PUMP Perform the following steps to ensure that the liquid fertilizer pump is calibrated properly: 1. Set the pointer, 1 FIG. 18, on the metering pump to a setting that corresponds to the desired liquid application rate. 2. Before seeding, accurately measure or carefully estimate the amount of liquid in the liquid fertilizer tank and note the beginning area reading on the monitor display. 3. Seed a significantly large area.
