4.2 FILL AUGER Figure 4: 10 inch Fill Auger DANGER! 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! Keep arms, hands and legs away from auger intake. Wear appropriate fitting clothing when working in the vicinity of an auger. Keep all guards and shield in place and inspect to ensure they are properly attached and intact.
4.2.1 Positioning the Auger NOTE: 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. 1. Ensure your tractor circuit is engaged in the correct direction prior to engaging the auger diverter valve. If circuit is already engaged direct the fan diverter valve to the fill auger position from the fan location, Figure 5.
4.2.2 Operating the Auger 1. Ensure that all screens and shrouds are in place and that the cleanout gate, on the bottom of each meter, is closed, Figure 8. 2. Activate tractor hydraulic circuit #4, and pull the diverter valve up to the auger circuit. 3. The handle on the auger tube is the control to operate the auger flighting in a forward or reverse direction. Figure 8 4.
4.2.4 Auger Transport Position NOTE: Fill auger should always be secured for transport, no matter how short the distance. Clean out auger prior to transport or storage. 1. Position the auger so that the tube is resting on the locking mechanism at the back of the aircart. In TBH configurations only, the hopper can be rotated down for transport, Figure 10. Figure 10 2. The locking mechanism must be used to secure auger when transporting at all times, Figure 11. Figure 11 3.
4.3 FILL CONVEYOR Figure 13: 800 Aircart with Fill Conveyor DANGER! Use extreme caution when moving the conveyor, 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! Keep arms, hands and legs away from conveyor intake. Wear appropriate fitting clothing when working in the vicinity of a conveyor.
4.3.1 Positioning the Conveyor NOTE: Ensure that the area in the vicinity of conveyor operation is free of obstructions and that all bystanders, especially children, are kept at a safe distance before positioning or operating the conveyor. 1. Ensure your tractor circuit is engaged in the correct direction prior to engaging the conveyor diverter valve. If circuit is already engaged, direct the fan diverter valve to the conveyor position from the fan setting.
4.3.2 Operating the Conveyor 1. Ensure that all screens and shrouds are in place and that cleanout gate on each meter is closed, Figure 17. 2. Activate tractor hydraulic circuit #4, and pull the diverter valve up to the auger circuit. Figure 17 3. Use either of the buttons located at the top and bottom of the conveyor to start and stop the conveyor, Figure 18. 4. Whether filling or unloading the aircart, the auger performs at its highest capacity when product is falling directly into the flighting.
4.3.4 Conveyor Transport Position NOTE: Fill conveyor should always be secured for transport, no matter how short the distance. Clean out conveyor prior to transport or storage. 1. Latch down the conveyor hopper then fold it up on top of the conveyor tube. Be sure to secure it with the tie down strap supplied. Figure 20 2. Arrange the conveyor so that the upper rest is positioned on the conveyor saddle at the front of the aircart, Figure 20. 3.
4.4 Bag Lift If equipped, the optional bag lift can be used for transporting bagged agricultural product from the ground to the top of the air cart. The bag lift has a maximum capacity of 550 lbs or ten bags of canola (50lb bags). The bag lift runs off the same hydraulic circuit as the auger or conveyor. To operate the bag lift the diverter valve must be switched to the auger or conveyor setting.
4.5 CASE DRAIN LINES You must also connect the case drain lines (two 1/2” hoses, one with a yellow band) to return hydraulic fluid back to the tractor reservoir. One case drain line is a 1/2” (13 mm) line from the fan. The other 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. Seed Hawk Inc.

4.7 METERING ROLLER The metering roller, Figure 25, is provided in each compartment. There are four different roller section types: canola, helical, straight fluted (bean) and chick pea. However, the canola roller is only available on hydraulic drive equipped aircart models. The helical roller section is designed to accommodate the majority of seeding products including small oil seeds, cereals, and granular fertilizer. The straight fluted (bean) roller is used for small pulses and granular fertilizer.
4.7.
4.8 SEED HAWK® PRESSURIZED METERING SYSTEM Figure 27: Pressurized Meters With the Seed Hawk® pressurized metering system product can be diverted to either air stream, Figure 27. This gives the Aircart ultimate flexibility by allowing the option of diverting any product to either the seed knife or the fertilizer knife. To change the air stream that a meter will deliver product to, adjust the diverter valve on the side of the meter body, Figure 28.
4.9 FAN(S) Connect the pair of 3/4” hydraulic lines (Fan one has a blue band, fan two has a red band) to supply the hydraulically driven fan motor. This tractor lever is locked in full pressure position while seeding. 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 system. Fan speed is indicated on the monitor panel in the cab. Set fan speed to effectively transport the seed.
Figure 29: Single Fan Air Damper 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, Figure 29, to set an effective air flow for each product. NOTE: 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.
4.11 GROUND DRIVE METERING The ground drive metering system is engaged by activating an electric clutch, Figure 30. A switch on the control panel in the cab toggles “ON” and “OFF” and a lamp in the switch indicates when the switch is toggled “ON”.

7.3.4 GROUND SPEED CALIBRATION All new systems require a ground speed calibration to ensure accurate area totals and accurate ground speed readings. Note: During the calibration the monitor is counting the number of pulses produced from the drill mounted sensor. The monitor will display the pulses counted in 400 feet. Procedure: 1. To complete the calibration, measure a course 400 feet long preferably on level ground with a start and finish point. Line up Tractor at the Start Point.
To begin, sufficient seed must be placed in the hopper above the meter to be calibrated to ensure full flow during the calibration procedure. Measure and record the weight of the calibration bucket and place under the meter. The calibration requires meter revolution input and speed input. A separate calibration must be done for each meter. Procedure: Step 1: Having Selected Meter (1, 2 or 3) Calibration, “Target 10.0lb/ac” is displayed. Press the Toggle Button.
Once this step is complete, highlight the “Start Box” using the Selector Knob and use the Enter Key or Toggle to select Start. Continue to Step 2. Step 2: The screen now displays the number of meter revolutions counted with “Continue” highlighted. Turn the meter a number of revolutions while catching the metered material in the catch bin. Stop turning the meter. The number of revolutions is displayed. Press Continue to save the information collected during the calibration procedure.
Step 6: Repeat steps 1-5 for each additional meter. NOTE: It is recommended that the monitor be powered off and on to ensure that all updated information is saved in the non volatile memory. NOTE: There is a line on this screen that reads “Cal Rate”. This is the application rate that will be applied if the gearbox setting is left at the 100 setting and this value will be reported back by the monitor while planting if the gearbox setting is not reset to the value displayed as the proper setting.
Low and High fan speed alarms can’t be acknowledged. The alarm condition must be corrected to clear the screen of the alarm warning and to quiet the audible alarm. If this alarm is going off in error, check the high and low alarm point settings by going to the sensor configuration menu, highlighting the sensor in question and pressing the “Settings” soft key.
8.0 HYDRAULIC DRIVE All aircarts equipped with the Raven Viper Pro™ monitoring system have hydraulically driven meters. These motors have a maximum speed of 113 RPM and a minimum speed of 2 RPM. Speeds in excess of the maximum may result in premature wear or failure of the motors. Reducing the rotational speeds of the motor below 2 RPM may result in erratic metering which may affect the seeding rate. Each hydraulic motor requires a flow rate of 1.0 gallons per minute. The maximum torque output is 26 ft-lbs.
3. Remove spur gear from agitator shaft, Figure 35. Figure 35: Spur gear removed 4. Substitute roller, Figure 36. Installing a roller is often easier done with the front cleanout door removed. 5. Replace the hydraulic motor and hydraulic motor mount. Tighten the flange nuts back onto the meter body. Replace hydraulic motor spacer and lynch pin onto roller shaft.
8.1 FILTER AND PRESSURE REDUCING VALVE There is a filter placed in-line with the hydraulic motors which is located at the front of the aircart near the diverter valve for the auger or conveyor. The filter is equipped with a blockage indicator which displays a red band when a pressure differential greater than 5 bar (72.5 psi) occurs. Note that low oil temperatures may give false blockage indication. To reset the blockage indicator press the plastic cover at the top of the indicator.
8.2 REMOTE CALIBRATION When performing calibration with the remote tank console, power up the Seed Hawk Viper Pro and select the Display Program list option when prompted. The Seed Hawk Viper Pro should remain on the Program Menu Selection screen while using the remote tank console. To begin the remote calibration of the meters mount the remote calibration console on the ram-ball and attach the electrical connector. Turn the console on using the blue power button.
Pressing the SETUP soft key brings up this screen. Turning decimal shift off will reduce the accuracy from two decimal places to one decimal place. Meter cal is the number of pulses per revolution. This number is dependent on the encoder inside the hydraulic motor and should not be changed from the default value of 60.
Pressing BEGIN from the calibration screen brings up this screen. The meter needs to be primed before calibration begins to ensure full product flow during calibration. Select prime meter roller to prime the meter. Do not include the product metered out during priming in the rest of the calibration procedure. Select start calibration to continue with the meter calibration. Selecting set bin height brings up another screen to specify the bin height for the bin level sensor.
