5. Now that the sprayer is attached to the tractor, prepare
to level the frame of the sprayer by securely support-
ing the front of the frame with a hoist.
6. Adjust the frame by moving the adjustment bolts (1) to
a position where the frame is sloping to the front about
one degree. This will allow the fluid in the tank to drain
into the sump when the sprayer is in use. Securely fas-
ten the adjustment bolts (1) using the Torque Values
Chart in the “Appendix” section on page 33.
Tractor/Great Plains
PTO Pump 1000-1 3/4” Hook-Up
1. Position the PTO pump on the tractor’s PTO shaft with
the coupler bolt removed on the splined end.
2. Push the coupler of the pump on to align with notch in
the tractor PTO shaft and install bolt.
3. Make sure there is adequate hose length to reach the
pump.
4. On the 1000 rpm 1 3/4 inch spline PTO pump, torque
the 5/8 inch Grade 8 coupler bolt to 210 ft-lbs and the
other 1/2 inch Grade 8 coupler bolt to 105 ft-lbs.
5. Rotate the PTO shaft by hand to make sure the bolts
clear the PTO shielding.
6. Attach the torque bar chain to the drawbar securely.
7. Hook the tarp strap in such a way that the slack in the
chain is taken up slowly when the PTO is engaged so
the torque bar does not bang.
8. Tie up any loose hoses with cable ties to prevent hose
damage.

9. With water in the sprayer tank and the pump, engage
PTO shaft slowly with tractor engine idling. Once the
system builds pressure, close agitation valve, shut off
boom-section switches and close throttling valves (if
applicable). Sprayers with automatic controllers do
not have throttling valves. The pump is now at dead-
head pressure. Adjust engine RPM so the spray pres-
sure reaches 80 PSI maximum on the nozzle pressure
gauge, or the PTO speed reaches the rated RPM
(1000), whichever is first. Never exceed the rated trac-
tor PTO RPM. This is the RPM needed to spray at to
prevent excess pressure on the sprayer’s plumbing.
Tractor/Hydraulic Pump Hook-Up
The hydraulic motor used on all liquid pumps is a 6 GPM
motor. If the tractor used on the sprayer does not have the
capabilities to adjust the remotes down to this flow, then a
hydraulic flow divider kit must be installed so that flow can
be controlled and to prevent operating the pump at exces-
sive speeds. See an Great Plains dealer.
To hook up the pump conduct the following instructions:
1. The pressure hose coming out of the tractor remotes
must be connected to the “A” port of the motor and the
return line connected to the “B” port. Before operating,
place a stop in the neutral position for the tractor hy-
draulics so that the hydraulic lever can only be moved
to the float and down positions. Refer to the tractor’s
operator manual or tractor dealer on information for
the neutral stop.
NOTE: Do not move the hydraulic lever into the neutral po-
sition while the hydraulic pump is running. To do so may
cause damage to the hydraulic pump.
2. To determine the correct setting of the flow rate, start
out with the hydraulic flow control valve set at a mini-
mum flow for the pair of outlets that operate the pump.
3. With water in the sprayer tank and in the pump, place
the hydraulic lever in the float position.
4. Open up the sprayer flow control valve to its maximum
setting.
5. Start the tractor and engage the pump by placing the
hydraulic lever in the down (forward) position.
6. Once the system builds pressure, close the agitation
valve, shut off the boom section switches, and close
the throttling valves (if applicable).
7. The pump is now at dead head pressure and the hy-
draulic control valve must be adjusted so the spray
pressure reaches 80 PSI maximum on the nozzle
pressure gauge. This process should be done with the
tractor throttle set at normal operating speed. Mark
this setting on the hydraulic control valve for future ref-
erence.
8. Open up the agitation valve and reset the throttling
valves (if applicable). Refer to Throttling Valve Adjust-
ment in the “Adjustments” section on page 21.
