Volumetric Meter Planting
In Singulator Plus™ planting with volumetric
a
seed
wheels, planting rate is determined by:
• row spacing
• crop and seed variant
• meter wheel selection, and
• meter drive configuration (which relies on the “pounds
per meter revolution” data in the following tables).
There are no other adjustments, but to achieve the
desired rate, calibration is strongly recommended, and
there is a recommended range of meter rpms, which
affects the range of ground speeds, shown in the
following tables. The optimal rpm varies with meter
wheel and seed type.
Volumetric planting uses “GRAN SEED CONTROL” or
“granular” mode. Singulated planting employs the seed
monitor in “PLANTER CONTROL” mode, and is covered
at “Singulated Planting Overview” on page 2.
Population Risk:
If the seed monitor is presently in PLANTER CONTROL mode,
follow the setup instructions carefully. Switching between
seeding modes can cause some planter configuration values to
be reset to defaults that are incorrect for your planter.
1. For your crop, determine your intended population, in
pounds/acre or kg/hectare.
2. For your crop, population and desired field speed,
verify the suitability of your seed wheel at the
intended population and field speed. See “Reading
a Volumetric Chart” on page 28.
Note: If a rate/speed table is not provided for your crop,
that crop has not yet been tested on the YP30/40
Planter planter.
a. Volumetric planting is referred to as “GRAN” or “granular” in the seed monitor manual and displays.
