The utility model belongs to the technical field of
agricultural machinery, and relates to an
agricultural machinery gearbox which comprises an input shaft, a driving transmission mechanism, a steering transmission mechanism and a planetary differential mechanism, a first hydrostatic transmission device and a second hydrostatic transmission device are arranged outside a gearbox body of the gearbox in parallel, and a main input gear is arranged on the input shaft. A first hydrostatic transmission input gear and a second hydrostatic transmission input gear are meshed with the two sides of the main input gear respectively, an input shaft of the first hydrostatic transmission device is in spline connection with the first hydrostatic transmission input gear, and an output shaft of the first hydrostatic transmission device is in spline connection with the driving input gear. An input shaft of the second hydrostatic transmission device is in spline connection with the second hydrostatic transmission input gear, and an output shaft of the second hydrostatic transmission device is in spline connection with the steering input gear. The
agricultural machinery gearbox has the advantages of being compact in structure, reasonable in
layout, fast in output response and the like.
