1. To change rates manually when in VR mode, simply touch the Up/Down arrow keys. This will change the Controllerto
the rate you select manually. To return to VR, simply touch the On/VR key to toggle back to VR mode.
Troubleshooting GPS-Based Seeding with PF3000
1. No Target Rate appears on the PF3000
• Has field been selected? Select target file (see PF3000 settings, Step 4).
• Check recipe to verify that it is valid.
• If recipe calls for zero rate as the default, do you have GPS signal, or are you outside of field?
2. No Actual Rate appears on PF3000
• Actual rate cannot be logged using the PF3000 with the Great Plains Precision Population Controller.
3. Target Rate appears on PF3000 but not on GP Controller Console
• Make sure GP Controller Console is set to VR Mode.
• Double-check all cable connections.
• Check Nominal Rates on both the PF3000 and on the GP Controller Console. These must be set to the same number.
4. Rates on GP Controller Console and on PF3000 do not match
• Check Nominal Rates on both the PF3000 and on the GP Controller Console. These must be set to the same number.
• Re-check GP calibration number with metering wheel and row spacing.
• The recipe rates from the PF3000 are in 4% increments. If the two rates are within this 4% range, the units are op-
erating normally.
• Check the target conversion number (PF3000 Settings, Step 6). If the recipe requires a target conversion number, i.e.
the recipe is for 25 which means 25,000 seeds/acre, the target conversion number will be 1000. In this case the Nom-
inal Rate on the PF3000 and on the GP Console should be near 25,000. See PF3000 Settings, Step 5 for calculating
Nominal Rate.
5. Population Monitor rate does not match GP Controller Console
• Make certain that PF3000 and GP Controller Console agree. If not, see Troubleshooting, Step 4 above.
• Re-check GP calibration number with metering wheel and row spacing.
• Re-check planter monitor settings: calibration number, row spacing, number of rows, swath width, seed, etc.
• When planting small size seeds and/or at high rates, if population monitor consistently indicates a lower population
than the GP Controller Console, contact monitor manufacturer for performance specs for that application.
Maintenance
As with any hydraulic system, contamination is the most common cause of performance problems and pre-mature wear.
Make a special effort to properly clean quick couplers prior to attaching the hoses to tractor.
1. Filter - All fluid is filtered through the high pressure filter (PN 18574) and it will provide protection to the hydraulic com-
ponents of your drive if properly maintained. It is equipped with a pop-out indicator to alert that the replaceable ele-
ment is clogged, and should be changed immediately if this situation occurs. Normal service life of the element will
vary based on the precautions that you take to minimize contamination at the couplers and routine service of the trac-
tor filtration.
To change the element:
a. Unscrew lower canister from filter, catching and disposing of used fluid.
b. Remove and discard element.
c. Install new element (PN 19856)
d. Clean canister threads and lube o-ring with hydraulic fluid, then re-install.
