Channel Setup Screen
Channel 1 setups are for the front hopper.
Channel 2 setups are for the rear hopper.
“Type” - Set this to either “Gran Seed Monitor” or “Gran
Fert Monitor” based on the type of material in each
hopper.
“Material Name” - Choose the name of the material
configured for each channel in steps 1 and 2 above.
“Sensor Constant” - [ 360 ]
“Gear Ratio” - [ 1 ]
“Channel Width” - is your Implement Width (swath) in
inches (cm). Precise row/swath data is found on
page 163 (for NTA907) and page 164 (NTA3007).
If the monitor inputs are correctly entered, the monitor is
a handy tool for fine tuning the variable rate gearbox
setting. If the rate reported by the monitor does not
match the desired planting rate, rotate the crank to adjust
the variable rate gearbox control arm slightly so as to
achieve the desired planting rate.
If the drill has the optional Variable Rate feature installed,
also set up a Controlled Material and an Actuator
Channel. See manual 166-263M for details.
Meter Rate Adjustment
Seed rate is determined by:
• Flute shafts (covered on page 84):
standard 2-star/1x rate, or
optional 3-star/1.5x or 4-star/2x rates
• Single/twin hopper metering.(covered on page 85)
• Seed meter Final Drive Range gearing
• Variable Rate Gearbox setting
The Seed Rate Manual charts are based on cleaned
untreated seed of average size and test weight. Many
factors affect meter rates including foreign material, seed
treatment, seed size, field conditions, and test weight.
Minor adjustments will be needed to compensate for
these factors. Initially set the rates according to the
charts, then calibrate for your material and conditions.
Calibration is also required to set up the monitor
Calibration Constant. With the correct Calibration
Constant and material density the monitor can be used
to help fine tune the variable rate gearbox setting.
