For a more efficient use of energy in combine harvesters a decoupling of the power train
between combustion engine and different drives is analyzed. Therefore all power sinks and
the essential load spectra for the layout of the drive system are identified. At the University of
Hohenheim a combine harvester was equipped with a CAN-Bus based measurement device to
determine the mechanical power at the combine chopper in action. Furthermore the effect of
the chopper driving speed and the design of the blades (standard compared to paddle blade)
on the power requirement were investigated and verified by a DLG e.V. straw distribution
measurement device.
