4. Hydraulic System:
a. Chemical Circuit:
The tractor hydraulic system must be capa-
ble of 11 GPM (42 lpm) at 2000 psi (13,800
kPa) to operate the chemical circuit pump.
Either closed-center or open-centered sys-
tems can be used.
A. Ace Pumps:
i. Closed Center Load Sensing:
(John Deere 6000, 7000, 8000 & 9000 Se-
ries, CaseIH Magnum & Maxxum Series,
Ford Genesis).
Purchase a Flow limiting Valve (Part No.
LS206 or LS304) from your dealer and in-
stall it on the inlet port of the ACE Pump
hydraulic motor.
Follow the detailed instructions found
at the beginning of the PUMP section of
the Fast catalogue.
ii. Closed Center Pressure Compensating:
(John Deere, except 6000, 7000, 8000 &
9000 Series, AGCO White).
Use
the Restrictor Orifi ce that is wire-
tied to the ACE pump. Install it in the
inlet port of the ACE hydraulic motor.
Follow the detailed instructions found
at the beginning of the PUMP section of
the Fast catalogue.
iii. Open Center:
(Steiger, Cougar and Panther).
Do NOT use the Flow Limiting Valve or
the Restrictor Orifi ce.
Follow the detailed instructions found
at the beginning of the PUMP section of
the Fast catalogue.
B. Hypro Pump:
i. Open Center Systems:
• Do not use an orifi ce in the pressure
adapter port.
• Start the tractor. Leave the selector
valve in neutral and achieve opera-
tion RPM and system temperature.
• Open the bypass screw 4 turns.
• With the pump inlet fl ooded, move
the selector valve to the Lower posi-
tion and allow hydraulic fl ow to the
motor.
• Adjust the bypass screw closed until
the desired spraying pressure Is
achieved. Account for agitation fl ow.
• Tighten the lock nut on the bypass
screw.
ii. Closed Center Load Sensing:
•
Do not use an orifi ce in the pressure
adapter port..
• Start the tractor. Leave the selector
valve in neutral and achieve operat-
ing RPM and system temperature
• Adjust the tractors hydraulic fl ow
control (Tortoise/Hare) to its lowest
setting.
• Close and lock the bypass screw.
• With the pump Inlet fl ooded, move
the selector valve to the Lower posi-
tion and allow hydraulic fl ow to the
motor.
• Adjust the hydraulic fl ow control
valve (Tortoise/l-Hare) until the de-
sired spraying pressure is achieved.
Account for agitation fl ow.
C. Boom Position:
The tractor hydraulic system must be
capable of 3 gpm (11 lpm) at 2350
psi (15,200 kPa) to operate the boom
position circuit. Either closed-center or
open-center systems can be used. An
orifi ce is located next to each cylinder to
control its rate of movement.
