Boom Operations
2007+ Sprayer Hydraulics
On newer sprayers, the hydraulics use a “live” system.
The tractor hydraulic pump may be left on during sprayer
operations. This requires 5-to-8 gpm flow.
The console toggle switches move up and down from
center off, and are auto-return. They must be held up or
down until an operation is complete.
2006- Sprayer Hydraulics
The tractor circuit is engaged only during the operation,
and the tractor lever determines the direction of cylinder
movement.
The console switches move only up, are detented, and
remain in the selected position until moved. The switch
may be operated before or after lever movement.
Refer to Figure 40
The “live” hydraulic controls come standard to operate
with “closed center” tractor hydraulics. To be used with
an “open center” system a conversion kit must be pur-
chased (part no. 833-427C). To install the conversion kit,
remove the plug from the end of the valve block (#14)
located on the top of the center boom section. Install the
conversion valve and coil into this location. Plug the
electrical cable into the open plug on the valve harness
and the conversion is complete.
Elevator Raising/Lowering
The elevator lifts and lowers the center section of the
boom, which raises and lowers the entire boom.
Refer to Figure 41
Lifting is performed by a hydraulic cylinder controlled by
a solenoid valve, which in turn is controlled by an up-
down/center-stop switch on the boom control panel in
the tractor cab.
The elevator is fully raised for folding.
Lowering is by gravity retraction of the cylinder. When the
switch is toggled down, the hydraulic circuit is put in float.
Lifting and lowering speeds may differ.
Boom Height
After calibrating the sprayer for the specific nozzle to be
used at a desired pressure and tractor speed, the main
field adjustment is the boom height.
Depending on which type of nozzle is being used, set the
boom height so that the correct overlap for that specific
nozzle is achieved. If the crop canopy is taller in some
fields than others, adjust the boom height accordingly.
Refer to the Nozzle Charts in the Application Guide to
determine the height of the boom.
In center-off, the elevator stays at the current position. In
normal field operations, the elevator is set to the desired
height, and left there for the field. Typically this is about
20in (51cm) above the crop canopy.
As necessary, wings are raised and lowered at turns by
the operator, and adjusted to accommodate uneven ter-
rain. The optional Autoboom system is useful on irregular
terrain.
