Abstract:
This contribution aims at determining the power loss in hydraulic circuits of the John
Deere S680i combine harvester travel gear. The individual elements of the circuit were measured,
followed by an energy intensity analysis. The analysis includes the calculation of pressure losses
in direct piping, local resistance, as well as pressure losses in the individual elements of the
circuit. Subsequently, power loss was calculated based on pressure losses. In the case of the John
Deere S680i combine harvester, the power loss equals 16.95 kW.
