The invention provides a high-horsepower hybrid power tractor driving system and a control method. The high-horsepower hybrid power tractor driving system comprises an engine, a generator, a battery pack, a main driving motor, a PTO driving motor and a mechanical coupling device. The engine is connected with the generator, the generator outputs electric power and is electrically connected with the battery pack, the main driving motor and the PTO driving motor through the inverter, the generator, the main driving motor and the PTO driving motor are connected with the mechanical coupling device, and the two output ends of the mechanical coupling device are connected with the transmission and the rear power output device respectively. The transmission is connected with a drive axle, and the drive axle is connected to a vehicle half axle and used for driving wheels. The complex working condition requirements of the tractor can be met, good fuel economy and emission performance are guaranteed, and meanwhile the advantages of being high in dynamic property and agricultural machine matching degree are taken into account.
