Boom Stability
Different cases of boom instability and boom lift issues are discussed below:
Problem(s)
Possible Cause(s)
Suggested Solution(s)
The boom is unstable in automatic mode.
If the suspension sticks or is too loose, the boom will
be unstable.
Ensure the sprayer’s boom suspension is operating
correctly and moving freely. If the boom is unstable
in manual mode, the height control system will not
make it more stable.
Dry friction pads.
If there are friction pads on the boom, ensure they are
well greased.
Wear in boom damper shocks
Check the boom damper shocks and replace them if
they are worn.
If the hydraulic settings are not calibrated correctly,
the boom may be unstable.
Perform a retune and redo the push test.
Roll sensors problem.
Check the mounting of the roll sensors.
Improper sensor alignment.
Ensure the height sensors are reading properly and
consistently. The sensors must be aligned and
mounted correctly. The sensor should point almost
perpendicular to the ground, and there should be no
obstructions between the sensor and the ground.
The boom(s) move all the way to the top in crop
mode.
The sensors are most likely reading off of the boom in
crop mode.
Ensure the sensors are aligned and mounted
correctly. The sensor should point almost
perpendicular to the ground, and there should be no
obstructions between the sensor and the ground.
