Operating Pump
Rotating drive line contact can cause death. KEEP AWAY! Do
not operate without guards attached and drive line securely
attached at both ends.
To operate the PTO pumps, engage the PTO shaft slowly
at the tractor’s idle throttle position. Slowly accelerate to
the desired PTO RPM. On a 540 RPM pump, the RPM of
the PTO would be the speed at which the dead head
pressure reaches 80 PSI or 540 RPM. On a 1000 RPM
pump, the RPM of the PTO would be the speed at which
the dead head pressure reaches 80 PSI or 1000 RPM.
Never operate the PTO pump without the tractor PTO shield in
place, and the pump torque bar firmly chained in place.
1. To operate the hydraulic pump, first make sure that
the hydraulic hoses are routed correctly so that the
pump turns in the correct direction. See “Hitching
with Hydraulic Pump” on page 20.
2. To run the pump, push the hydraulic lever in the
“down” position.
3. When stopping the pump, push the hydraulic lever in
the “float” position.
Note: Do not move the hydraulic lever to the neutral posi-
tion while the hydraulic pump is running. To do so
may cause damage to the hydraulic pump.
Unloading Materials
Sprayed chemicals are normally diluted in water for
application, and cannot be recaptured and stored for re-
use.
Refer to Figure 45
If a small amount of material remains in the main tank at
completion of spraying, one method of disposing of it is
to apply it to the same fields. To avoid an overdose of
material, reduce the rate or further dilute the tank con-
tents with water (but don’t use the Flush tank water for
this - reserve it for final tank flush and clean-out).
If material must be drained from the tank, rather than
applied via boom, drain at the Whirlfilter sump
.
Do not attempt to drain the main tank by removing the main
sump cap. Potentially hazardous materials will spray in ran-
dom directions as the clamp is being removed.
