Boom explanation (spray boom)
The spray boom is the horizontal spraying structure mounted on the sprayer that distributes liquid evenly across the crop
Function
The boom carries multiple nozzles spaced evenly along its length.
It ensures uniform spray coverage over a wide area in one pass.
The liquid from the tank is pumped through hoses to each nozzle.
Key characteristics
Working width: typically 8–12 meters (depending on version)
Foldable design: allows safe transport on roads and easy storage
Height adjustment: helps adapt to different crop heights
Section control (on advanced setups): allows parts of the boom to be switched off to reduce overlap and chemical waste
Stability: often equipped with dampers or suspension to reduce bouncing on uneven terrain
Why the boom is important
The boom determines:
spraying accuracy
coverage efficiency
chemical usage
crop protection quality
A well-adjusted boom height and stable movement are essential for preventing drift and ensuring even application.
