The invention relates to the technical field of tractors, and discloses a hybrid power system and a tractor. The hybrid power system comprises an engine, a generator, a battery, a driving motor, a power output device, a rear axle, a brake, a first gear shifting device and a power transmission module. The power transmission module comprises a planet wheel assembly, a first transmission assembly, a second transmission assembly and a third transmission assembly. The engine output shaft is connected with the power output device, the driving motor is in transmission connection with the sun gear, the sun gear is in transmission connection with the planetary gear, the planetary gear is in transmission connection with the gear ring, and the planetary carrier is connected with the planetary gear. The engine is connected with the generator, the brake is arranged on the gear ring, and the generator is in transmission connection with the gear ring through the first gear shifting device. The planet carrier is connected with the rear axle, and the generator is connected with the battery which is connected with the driving motor. According to the hybrid power system, the system is simplified, and the cost is saved.
