C. HYDRAULIC SYSTEM
SPRAY BOOMS–
Hydraulically folding the extensions of the 60/80/90 foot boom system and adjusting
spray valves essentially turns it into a 60 foot boom. (continue reading this section for more information) Manu-
ally folding the outer extensions of the 60/80/90 foot system, adjusting spray valves and recalibrating the spray
console essentially turns it into an 80/90 foot boom (see the section on the spray system and the section on
calibration for more information on the console).
The spray booms are controlled by an electro-hydraulic system. This system consists of operator manipu-
lated switches located in the sprayer’s cab and hydraulic cylinders attached to the booms. It provides control of
lift, level, horizontal extension, and vertical extension.
All STS spray booms are equipped with a hydraulic breakaway
circuit. When folded out as an 80 or 90 foot spray boom, a one-way
hydraulic circuit on the outer boom section provides outer boom
breakaway functions. The outer breakaway is self-resetting and will
return to normal operating position after it has cleared the hazard (fig.
4.23-1).
