Operating the Sprayer Pump
The sprayer pump and plumbing system are
located in the left pod on the center section of the
sprayer. Open the pod door by inserting your
hand in the slot. Press the latch against the door
and slide the door up.
The sprayer pump is a hydraulically driven
centrifugal pump. It is not self-priming. If the
pump is run dry for any length of time, the internal
seal may overheat. If this occurs, turn the pump
off immediately and let it cool.
To operate the spray system, add clean filtered
water to the main tank. Follow the procedures
on page 31 for bottom filling the main tank or
page 32 for top filling the tank. Refer to page 84
for instructions on operating the sprayer when it is
equipped with a rear tank.
Before starting the pump, the liquid level must be
higher than the pump to assure proper priming.
The volume of liquid should be enough so that
liquid always circulates through the pump. After
water has been added to the tank, turn the valves
to the normal spray position:
1. Turn the main suction valve A so that the
direction arrows on the handle are pointed
towards the tank and the sprayer pump.
2. Close the bypass valve B.
3. Open the agitation valve C.

4. Place the run/hold switch on the MT-3405 rate
controller to the “HOLD” position and the

5. Increase the reel speed dial to maximum.
Increase the conveyor speed control dial to 6
(refer to the section on Header Controls in the
Self-Propelled Windrower Operator’s Manual
for the location of the speed control dials).
NOTE: The reel speed control and conveyor
speed control dials may require adjustment prior to
normal sprayer operation. Follow the instructions
on page 36 for calibrating the sprayer.
