Electrohydraulic header height
control for combine harvesters
EMR
The variety of uses and harvesting
performance of combine harvesters
can be increased with the aid of
electronic and sensor systems in
addition to hydraulic systems.
Complex controls make for greater
safety and relieve the burden on the
machine operator.
System solutions
Functions
U Cutting table guided parallel to
the ground
U Slope compensation of the
cutting table, optionally with
the control unit EMR-D
EMR operating modes
1. Transport mode:
Active damping of cutting table
vibrations while driving
2. Position control:
Cutting table is maintained in the
preselected position
3. Distance control:
Cutting table is maintained at the
preselected cutting height
4. Ground pressure control:
Cutting table is guided over the
ground with constant contact
pressure
Electrohydraulic fan control EHL
Flexibility is one of the main advantages
of hydraulic fan drives.
Electronic control of such systems
yields further advantages, such as:
U Marginal temperature deviations
due to the high control
quality
U Lower fuel consumption
U Lower emission of noise and
exhaust gases
Three different system solutions are
available for different areas of use.
