Agitation
The agitator bleeds off some of the material flow and
recirculates it through orifices at the bottom of the tank. It
helps maintain constant concentration with materials that
might otherwise tend to precipitate, sediment or stratify.
Refer to Figure 22
The Agitation Valve
controls the amount of recircula-
tion. Use the agitation gauge to set a reference pressure
for the agitation.
Unfolding and Folding Booms
This is an overview of boom operations. For full details,
see the Boom Operator manual.
On the standard 3P300 sprayer, each boom is on a sep-
arate hydraulic circuit. With either electro-hydraulic
option, the booms are on a common circuit but may be
operated independently. With optional controls, the color
code is:
Regardless of circuit connections, boom sides may be
folded and unfold individually or simultaneously. There is
no risk of arm interference.
In addition to folding for transport and storage, the initial
movement during folding is a slight boom tilt, which may
be used to clear obstacles, particularly during turns.
An arm may be left folded during a field pass if needed.
Be sure to shut off the nozzles for that side.
Hydraulic Elevator Option
Raise and lower to the desired boom height using the
tractor hydraulics. Make sure the boom doesn’t settle
hydraulically (lower in height) during the operation of the
sprayer. With optional controls, the color code is:
