2.7 Preceding & Trailing
Implements
Adding a preceding or trailing
implement to the CultiPress will
affect the stability and handling
of the machine both in transport
and work.
2.7.1 Hitching a Disc Cultivator
to the CultiPress
1. Remove the transport straps from the
disc cultivator, exercise great CARE
when extending the axle cylinder.
2. Reverse the disc cultivator up to the
CultiPress drawbar ensuring that the
two drawbars are aligned allowing
a slight clearance to enable the
machines to be coupled together.
3. Lower the disc cultivator to the ground.
4. Connect the four hydraulic hoses from
the CultiPress into the disc cultivator
rear outlets ensuring that the two
wing hoses are together and the two
drawbar cylinder hoses are together.
Ensure that the folding circuits and lift
drawbar circuits are coupled correctly.
5. Raise the CultiPress drawbar above
the disc drawbar (200mm approx.).
Depth control shims may need to be
removed.

2.6 Air Brake Coupling
Procedure
Please refer to the following procedure
when coupling or decoupling any item of
Simba 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.
2.6.1 When Coupling
1. Reverse up to the machine and
connect the machine to the tractor as
instructed to in Section 2.4.1.
2. 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.
2.6.2 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.
