4.3 Main Lift Sensor Installation
1. The main lift mounting bracket (B21) is the bracket with the longer mounting flange.
2. There are a variety of ways to mount the main lift bracket on most sprayers. The bracket
should position the sensor approximately in the center of the sprayer, forward of the
boom. An example of this mounting is illustrated in Figure 8.

3. Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable through hole
and behind the bracket.
Figure 8: Example Mounting of the Main Lift Bracket
Avoid mounting the main lift sensor over or near a wheel-track. Measurements
from the wheel-track do not provide an accurate crop height and will cause
measurement and control error.
Ensure the bracket does not collide with any other part of the sprayer throughout
the full range of main lift motion.
