2.5 Air Brake Coupling
Procedure
Please refer to the following procedure when
coupling or decoupling any item of Great
Plains machinery fitted with an AIR brake or
AIR and HYDRAULIC brake system. Please
note that this procedure does not apply to
any machines fitted with a HYDRAULIC
system ONLY.
2.5.1 When Coupling
1. Reverse up to the machine and
connect the machine to the tractor as
instructed to in Section 2.4.1.
2. Transportation / Installation
2. With the machine connected couple
the air lines. When coupling ensure the
yellow line is attached first followed by
the red line.
3. Your brake hoses are now attached
and are ready for operation.
4. Continue with the coupling process as
instructed in Section 2.4.1.
2.5.2 When De-coupling
1. Bring the machine to the parking
position as instructed to in Section 2.9.
2. With the machine still connected to
the tractor remove the red brake line
followed by the yellow line.
3. Your brakes will now be ON and will
hold, ensuring they have been adjusted
and maintained correctly, the machine
in position. Note: if the machine‘s tank
is drained of air once all lines have
been detached the brakes will come off
(same situation as pushing the shunt
valve).
4. Continue de-coupling the machine until
it is fully disconnected.
By following the above instructions
you will see that at NO point
in the coupling or decoupling
process has the red line been
left in the tractor on its own.
This is intentional and should be
considered the ‘rule’ to coupling
the hoses.
3. Couple the hydraulic hoses to the
tractor ensuring that the two wing
hoses (yellow) are together, the lift axle
cylinder hoses (red) are together and
the drawbar cylinder hoses (green) are
together. There is also a single hose
(blue) to control the wing lock.
4. Raise / lower the hitch into position
using the drawbar cylinder. Reverse
the tractor and couple up to the tractor
drawbar clevis.
Do not use the tractor pick-up hitch
to attach the machine to the tractor.
This could cause damage to the
tractor and the machine.
4. Move the parking stand to the work
position.
5. If the machine is already folded it is
now ready for transport. If the machine
is unfolded please refer to 2.6.2.
Ensure that the wing lock is engaged
correctly before transporting the
machine.
