Hydraulic Drive Planting

Monitor Configuration
Hydraulic drive meter rate is set directly on the seed
monitor in the tractor. Consult the monitor manual for
detailed instructions, which may vary slightly over time
with firmware updates to the monitor system.
Enter/update your planter configuration (width/row-count,
single-row/twin, disk cell count, etc.). Once entered,
specify the population directly in seeds/acre or seeds/ha.
Enter meter RPM limits for your disk (see “
Meter RPM
Limit Charts ” on page 19).
 NOTE:
For consistent results, and least meter wear, do not exceed
the recommended ground speed.
Refer to the DICKEY-john
®
Manuals for detailed
instructions.
 NOTE:
The monitor must be in User Level 2 to change some of
these parameters.
1. For a crop not previously planted with this planter,
create a Material Name for the crop. Selecting a
named material is a required step in later screens.
2. Verify, setup, or update the Material record for the
singulated seed to be planted.
The table at right lists the parameters that need to be
reviewed or set. <angle bracket> values are your
choice/preference when not from meter rpm chart.
3. Verify, setup, or update the Channel assigned to the
planter’s hydraulic drive. If the monitor resets to
defaults, Gear Ratio may be incorrect.
Count rows individually for # Seed Rows. A twin pair
(if both openers are in use) counts as 2 rows.
Channel Width is the swath.
4. In the Material Library screen, makes sure that the
Material (SOYBEANS in our example) is assigned to
the Channel (CH 1 in our example) which controls
the planter’s hydraulic drive.
5. Perform a Valve Calibration for the control channel.
6. Switch the seed monitor from Setup/Configuration
mode to Operate mode. Load seed. Move the
planter to the field.
