4.
Unit directly controlled directly from the tractor.
-
Connect the equipment’s hydraulic hoses to the tractor’s two double-action
hydraulic spool valves with the feed conveyor connected to the tractor’s
priority regulated supply.
Unit with spool valve.
-
The spool valves are fitted with a pressure limiting valve set at 180 bars.
5.
The spool valve must be linked directly to tractor pump pressure via its single-action
spool valve with the return always routed directly and unrestrictedly to the
tractor’s fluid reservoir.
6.
Avoid connecting to a double action tractor spool valve (pressure loss) unless the
tractor spool valve makes provision for this.
7.
The hydraulic pressure line is always located close to the pressure limiter on the straw
blower spool valve; it carries a red collar. The return hose carried a blue collar.
OPTION:
8.
Tractor with fluid flow that exceeds 45 l/min.:
Provide a flow divider to be installed on the straw blower upstream of the
“PRESSURE” orifice on the spool valve pack, or contact your dealer to check whether
it is possible to adjust tractor fluid flow rate.
9.
Closed circuit tractor: (e.g.: John DEERE)
a- To operate the equipment without posing a problem to the tractor, engage the
tractor spool valve and immediately operate the equipment’s hydraulic functions.
b- As soon as the equipment’s hydraulic functions have been used, return the tractor’s
spool valve to NEUTRAL.
c- For earlier models of John Deere tractors (prior to the 6000 series), check that the
tractor’s hydraulic system is not vibrating and that the equipment’s return hose is
connected to the tractor’s filter bowl; this is to avoid CAVITATION and pump
depriming (if you experience problems, contact your John Deere dealer)

Read sticker page 12 Ref: 892 640.
All types of equipment (direct tractor control or spool valve) require electrical power:
-
Connection is made to the battery from a direct electrical line
-
Voltage: 12 volts DC
-
Section for both conductors: 2.5 mm². The brown wire is to be connected to battery
+, and the blue wire to battery -.
