The invention relates to a hydraulic system (100) for a work machine. The system comprising: a main hydraulic machine (102) connected to an output shaft (104) of an engine (106) of the work machine for providing power to working hydraulics (110) of the work machine; a main pressure line (108) connecting the main hydraulic machine to the working hydraulics; a support hydraulic machine (112) connected to the output shaft; a hydraulic accumulator (114); a discharge valve (116) connected between the accumulator and an input side (118) of the support hydraulic machine; a charge valve (120) connected between an output side (122) of the support hydraulic machine and the hydraulic accumulator to selectively allow a flow from the support hydraulic machine to the hydraulic accumulator; a flow support valve (124) connected between the output side of the support hydraulic machine and the main pressure line to selectively allow a flow from the support hydraulic machine to the main pressure line; and a hydraulic tank (126) connected to the input side of the support hydraulic machine.
