2.6 Hydraulic Hose Hook-
up
Escaping fluid under pressure
can have sufficient pressure
to penetrate the skin causing
serious injury. Avoid the hazard
by relieving pressure before
disconnecting hydraulic lines.
Use a piece of paper or cardboard,
NOT BODY PARTS, to check for
leaks. Wear protective gloves and
safety glasses or goggles when
working with hydraulic systems.
If an accident occurs, seek
immediate medical assistance
from a physician familiar with this
type of injury.
Only trained personnel should work on
system hydraulics!
Great Plains hydraulic hoses are colour
coded to help you hook-up hoses to
your tractor outlets. Hoses that go to the
same remote valve have the same colour
handles.
The fan pressure hose (black) must be
connected to a circuit capable of continuous
flow at high volume.
To distinguish hoses on the same hydraulic
circuit, refer to labels at the hose ends.
Low Pressure (Case) Drain Connection:
Attach case drain hose to low pressure
drain connection in order to protect fan
hydraulic motor seals.
Connect low pressure motor return hose,
marked “SUMP”, to a high volume low
pressure return port. The sump line is
distinguished by a ¾in BSP connector.
For the hydraulic fan, connect the hose with
a retracted cylinder symbol to the pressure
side of the motor.
The fan motor further requires hook-up
of a (third) case drain line, which returns
lubricating/cooling fluid.
2.7 Brake Hook-up
Two braking (trailer braking) systems are
available for the Centurion; a dual-line air
system, and single-line hydraulic system.
In both systems, the tractor’s trailer brake
remote port(s) operate a hydraulic slave
cylinder on the drill. Tractor trailer braking
systems are normally integrated with the
tractor brakes, and operate the trailer
brakes when tractor brakes are used
during tractor movement.The trailer braking
system may or may not be integrated with
the tractor parking brake system. Trailer
brakes typically are not automatically
engaged when the tractor transmission is
in Park, and may not be engaged by any
tractor Emergency Brake.
Make sure the operator
understands when drill brakes
are engaged and when they are
released.
Also understand and comply with tractor
operational restrictions when trailer brakes
are used. For example, it is generally
necessary to inter-tie split brakes, and
avoid differential (steering braking) if trailer
brakes are used.
