The invention discloses a hybrid power transmission device for a high-horsepower tractor. The hybrid power transmission device comprises a torsion vibration reduction input module; the axial clutch device is connected with the torsion damping input module and used for controlling the power flow of the torsion damping input module; the power shunting module is connected with an EM1 motor and is connected with the axial clutch device; and an EM2 motor is connected to the gear module, and the gear module is connected with the axial clutch device and the power dividing module and used for controlling the power flow direction of the power dividing module and the EM2 motor. The hybrid power technology is adopted to replace hydraulic mechanical stepless speed change, meanwhile, gears are simplified, the technical problem of an existing high-horsepower tractor transmission device is avoided, the hybrid power technology E-CVT scheme is adopted, power interruption is avoided in an operation mode, the rotating speed of an engine is adjusted to the optimal working point through a planet row, and the transmission efficiency of the high-horsepower tractor is improved. The electric vehicle has the functions of pure electric driving, engine starting and stopping, braking energy recycling, engine direct driving, low-speed cruising in-situ charging and the like, and the endurance mileage anxiety is avoided.
