Abstract: A method and arrangement for controlling a function of a work implement utilizing a device including a source of pressurized fluid (1), a circuit of pressurized fluid (2) for driving the work implement, an electronically controlled hydraulic valve (5) being arranged in the circuit of pressurized fluid (2) for controlling the function of the work implement, a control unit (4) for controlling the hydraulic valve (5) based upon a signal from a control member (3) for transmitting a control command to the control unit (4), wherein the control unit (4) is arranged for controlling the hydraulic valve (5) in accordance with a smooth mode function or an abrupt mode function. The opening time for opening the hydraulic valve (5) to a predetermined opening degree is changed when switching from one operating mode function to the other operating mode function.
