Opener Hydraulic System
Operation
Basic function of the system:
• Tractor remote is set to continuous ow connected
to the “Pressure” port on the Opener Control Block.
• Control the Lift-Lower and packing pressure functions
through JEM display or X35 monitor.
WARNING: Openers will drop with full operating
force if the JEM display or X35 monitor is
rebooted with hydraulics running.
• Flow requirements during operation will be minimal in
most conditions (3-4 GPM max) (11-15 lpm) but large
changes in terrain (drainage ditches, terraces, water
runs) will cause larger ow rates for short intervals.
Minimum oil ow rate for the opener circuit would
be 18 GPM (68 lpm); 25 GPM (95 lpm) is optimal.
Lower ow rate = slower operation on headlands.
Flow requirements are highest while lifting/lowering
openers at headlands.
Lifting/Lowering
• Flow can be set to as much as the tractor can provide
without losing too much fan speed during lifting and
lowering of the openers.
• Pressing Opener “UP” button on the controller will lift
the openers fully up by shifting solenoid valve “S1”
to gland side of opener cylinders.
• Pressing Opener “DOWN” button on the controller will
lower the openers all the way down and lock them
into working position by shifting solenoid valve “S1”
to its default position of ow straight through to butt
end of opener cylinders.
WARNING: Default valve position is openers
down when applying ow at “Pressure” port.
• The system will remember the last mode (“UP” or
“DOWN”) that it was operating in and operate in that
same mode at next start up.
Note: If the controller is not present or connected,
the tractor remote can be used manually
to lift and lower the openers although no
pressure control will be available; pressure
down will be limited to the default of the
reducing relieving valve “S2” (200 psi)(1379
kPa).
