Hydraulic Pump Hookup (Option)
The hydraulic pump used has a 7 gpm (23 liters/min.)
motor. If the tractor used 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 to prevent operating the pump at excessive
speeds. See a Great Plains dealer for more information.
If the tractor has only one circuit capable of continuous
flow or only one capable of adjustable continuous flow,
reserve that circuit for the pump, and use another for the
main applicator functions.
1. Connect the pump hydraulic hoses to suitable tractor
remotes.
Refer to Figure 15
2.
The pressure hose coming out of the tractor remotes
must be connected to the motor inlet port:
“I”, Base end on hose label),
and the return line connected to the motor outlet:
“O”, Rod end on hose label.
3. Before operating, place a stop in the neutral position
for the tractor hydraulics so that the hydraulic lever
can only be moved to the float and down positions.
Refer to the tractor operator manual or tractor dealer
on information for the neutral stop.
4. See page 78 for setting flow rate.
Raise Parking Stands
Refer to Figure 16
Heavy Object Hazard:
Use the lifting handle
. Push leg against frame while raising
or lowering. The leg weighs approximately 45 pounds (20 kg).
The leg could cause injury if you lose control of it while
raising or lowering.
1. Use tractor 2-point hitch and the fold/lift circuit to
slightly raise the applicator. See “Raising/Lowering
Applicator” on page 51.
2. Remove cotters from pins .
3. Grasp the lifting handle. Use an assistant or
shoulder to hold leg against frame and inside
flanges.
4. Remove the pins .
5. Lift or lower the stand straight up or down.
6. Re-insert pins. Secure with cotters.
Equipment Damage Risk:
DO NOT move the hydraulic lever into the Neutral position
while the hydraulic pump is running. To do so may cause
damage to the hydraulic pump.
