Structure and Functions
5.6.3 Bowden cable operation
Fig. 44
The individual hydraulic components of the
machine are connected to a control block. To
ensure the oil supply, the control block is
connected to the hydraulic system of the tractor
via a double-acting control device or a single-
acting control device and a free return pipe.
If the machine is equipped with an on-board
hydraulic system, it is not necessary to connect
the machine to the hydraulic system of the
tractor.
The Bowden cable serves to operate the
hydraulic functions of the machine from the
tractor if the oil circulation between tractor and
machine has been switched on via the control
device on the tractor.
One control device is required for each function
of the machine.
The Bowden cable operating element:
• is mounted on the tractor within view and
easy reach of the operator,
• is equipped with one or several control
device(s).
The control devices are in touch-control or in
latch-in design:
• In touch-control design for folding,
swivelling or sliding movable machine parts,
e.g. discharge doors, hydr. counter-cutters,
support stand etc. The function is only
carried out when the control device is
activated and kept hold of. As soon as the
control device is released, it returns to its
neutral position and the action is stopped.
• In latch-in design for movements requiring
continuous action for constant loads, e.g.
hydraulic motor of discharge conveyor.
The control devices can be set to a maximum of
3 positions:
• Function I,
• Neutral position,
• Function II.
