6.6 Main Lift Sensor Installation
1. Mount the main lift bracket under the valve block between cross member. 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 13.

2. Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable through hole
and behind the 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.
