The invention relates to the technical field of tractors, in particular to a hybrid power system and a tractor. The hybrid power system comprises an engine, a first motor, a second motor, an energy storage unit, a clutch, a power output device, a rear axle, 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 planet wheel assembly comprises a sun wheel, a planet gear, a planet carrier and a gear ring, the engine output shaft is connected with the power output shaft through the sun wheel, and the first gear shifting device is arranged between the engine output shaft and the sun wheel. The first motor input shaft is connected with the engine output shaft through the first transmission assembly, the second motor input shaft is connected with the gear ring through the second transmission assembly, the rear axle output shaft is connected with the planet carrier output shaft through the third transmission assembly, and the first motor and the second motor are connected with the energy storage unit. According to the hybrid power system, the system is simplified, and the cost is saved.
