2. Mount the main lift bracket as shown in Figure 3 for 4630 or Figure 4 for R403x. The
bracket should position the sensor approximately in the center of the sprayer, forward of
the boom.
3. Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable down the center
of the main lift bracket tube.

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.
