RADAR Erratic When Above Crop Row
          

Symptoms
Displayed ground speed is erratic when RADAR sensor is above crop row.

Situation or Problem
Tall standing crops or vegetation can interfere with RADAR signal causing ground speed measurement to be erratic. Depending on row spacing, location of factory mounted RADAR sensor may be above crop row.

Summary
RADAR sensor can be mounted in alternate location that is not above crop row. If it is necessary to fabricate a bracket it is important to maintain proper mounting height and angle of sensor for correct RADAR operation. Consider following guidelines when changing location of RE152877, RE184684, and RE206770 sensors. If RADAR sensor is moved calibrate sensor per Operator’s Manual instructions.

Install RADAR sensor:

18-30 inches from ground (lower is better but sensor should not be mounted lower than 18 inches or at lowest point under tractor)
As close to centerline of tractor as possible
Pointing straight forward or aft (may be offset slightly as required) in relation to tractor
With lens at 45 degree angle to ground
Away from rotating shafts, tires etc. (in front, to sides, and behind)
