Radar Calibration
At the first opportunity to operate the planter in the field
(with or without planting), the radar component of the
seed monitor needs to be calibrated. The seed monitor
manual describes the procedure.
Potential Radiation Hazard:
Review radar caution on page 3.
Note: The planter must be in the lowered/field position for
this calibration. The angle of the sensor changes
when the planter is raised, and readings during
planting will be incorrect if calibrated in the raised
configuration.
Note: Due to this angle change, seed monitor speed
readings will not match tractor speedometer read-
ing during transport.
