05/06
With the system running it will now be
possible to set the desired fan speed at the
tractor.
You should consult with your local
dealer for further details regarding your
specific tractor’s hydraulic needs.
NOTE:
It is important that the operating
temperature of the oil does not exceed
90°C. Damage may occur if operated
above this temperature.
Fig. H3 Flow Control Valve.
Hydraulic Connections and Hose Kit
All quick release couplings required to
connect the Air Seeder to the tractor have
been supplied with your machine. Also
included is a hydraulic hose kit, clamps and
fixing hardware to fit your implement for all
rear tow models.
Not included in the hydraulic kit
however, are any hoses that may be
required to run the return oil flow directly
back to the tank on the tractor itself. Each
tractor will require its own hoses and
operators
should
contact
their
local
authorized dealer for further instructions.
It is important that all return hoses
fitted to the tractors hydraulic tank are
placed below the reservoir oil level.
Case Drain
It is important to fit the case drain
directly to the tank or through a dedicated
case drain line that may already exist on the
tractor. Case drain pressure
MUST NOT
EXCEED
specifications (refer page 13).
Seal damage will occur if case drain is
restricted in any way.
DO NOT
restrict the return flow by using
small hydraulic fittings.
Connecting the Seeder Hydraulics to the
Tractor
There are 3 hydraulic hoses that must
be connected to the tractor to operate your
Air Seeder (refer Fig. H4).
1.
Return Hose (¾“ SAE100R2) with a ¾”
safety male (Tema) breakaway at the
tractor. Connected direct to tank or
through remotes, using the female
TEMA fitting.
2.
Case Drain Hose (3/8” SAE100R1) with
a ½” safety male (Tema) breakaway at
the tractor. Connected direct to tank.
3.
Pressure Hose (3/4” SAE100R2) with a
½” standard male breakaway at the
tractor. This hose is connected directly
to the existing tractor’s hydraulic circuit.
