  • Construction machines usually have a main drive, which is for example a diesel engine on. Such main drives drive one or more main functions of the construction machine. Such main functions are in particular driving movements.
  • one or more auxiliary drive units are often present on construction machines, are driven by the aggregates, such as hydraulic pumps. These units are often optionally connected to construction equipment or are considered as an independent functional unit and are therefore referred to as cultivation units for this reason.
