Hydraulic System

9.5.1 Special Safety Instructions

•

Depressurize the hydraulic system before doing any work on the hydraulics.
Hydraulic fluids escaping at high pressure can cause serious injuries. Seek medical
help immediately should injuries occur.

•

Work on the hydraulic system, especially on the accumulators, should be done by
specially trained personnel only!

•

Fill accumulators with the specified gas only.

9.5.2 General Information

The tractor supplies the pressure for the round baler
hydraulic system via pressure hoses. Of the various
components, the shut-off tap (1) on the left hydraulic
cylinder deserves special mention. It is designed as a
safety device to prevent the tailgate from shutting
unintentionally.

Position

“a”

The hydraulic cylinder return is blocked.
The tailgate cannot shut. When working
inside the bale chamber when the
tailgate is open, always set the shut-off
tap in position 

“a”

.

Position

“b”

The hydraulic cylinder return is open.
The tailgate can be shut. Always make
certain to return the shut-off tap to
position 

“b”

 after finishing work inside

the bale chamber or on the tailgate so
that the tailgate can shut.
