Abstract:
A working vehicle comprising:a working implement supported by the working vehicle to be displaceable by a hydraulic actuator; and a controller for generating a control output signal for controlling a position of said working implement in response to a control input signal, with reference to predetermined control characteristics; wherein said control characteristics include at least a first control characteristic having a predetermined time-dependent rate of increase in a quantity of pressure oil supplied to said hydraulic actuator, and a second control characteristic having a higher time-dependent rate of increase than said first control characteristic, said controller refers to said second control characteristic for generating said control output signal, if said control input signal results from a variation in a set signal from a setter for setting a target level of said working implement, and said controller refers to said first control characteristic for generating said control output signal, if said control input signal results from a variation in a detection signal from a displacement detecting sensor for detecting a displacement of said working implement.
