The invention discloses a hydraulic operating handle for farm machinery. The hydraulic operating handle comprises a handle ball, an operating lever, a transverse shaft, a rotary plate, a dead axle, a support plate, a gear-reversing switch and a neutral switch, wherein the rotary plate is a U-shaped plate composed of a bottom plate and two side plates, the bottom plate of the rotary plate is mounted on the support plate by the dead axle, the transverse shaft vertically penetrates the side plates of the rotary plate, the operating lever is vertically and fixedly connected with the transverse shaft, the gear-reversing switch is connected with the rotary plate and judges the motion direction of the operating lever according to the rotation direction of the rotary plate so as to send gear-reversing signals, advance/retreat is realized, and the neutral switch is fixed on the rotary plate and rotates along with the same so as to stop/operate the machinery. The motion direction of the operating lever is judged by the gear-reversing switch, advance/retreat is realized, and the hydraulic operating handle is simple in structure and convenient to operate. The neutral switch detects whether the operating lever is neutral or not so as to stop/move, and travelling needs are satisfied. The handle ball is provided with several function buttons, and agricultural machinery needs of static hydraulic driving are met.
