Abstract
An implement has an internal combustion engine and a hydraulic system that can be driven by the internal combustion engine for bringing about a working movement. Furthermore, an energy accumulator is provided for the storage of energy in an accumulation phase in which the output delivered by the internal combustion engine is greater than the output currently required by the hydraulic system, and for the delivery of energy in a discharge phase in which the output delivered by the internal combustion engine is smaller than the output currently required by the hydraulic system. The energy accumulator thus serves for balancing output peaks and valleys such that the internal combustion engine may always be operated within an optimum range of rotational speeds.
