The invention discloses a tractor hybrid power system with an extended-range fuel cell and a control method. The tractor hybrid power system comprises an internal combustion engine assembly, a generator assembly, an extended-range fuel cell assembly, a power battery, a driving motor assembly, a power coupling device, a traveling device and an operation device assembly, wherein the internal combustion engine assembly and the extended-range fuel cell assembly serve as a hybrid power source to output power to drive the traveling device and an operation device, meanwhile electric energy is generated to charge the power battery, the extended-range fuel cell assembly comprises a fuel cell body, an air pressurization assembly and a methanol reforming assembly, and the methanol reforming assemblyand the air pressurization assembly provide hydrogen and compressed air for the fuel cell body. The control method comprises five driving modes and two power generation modes. The tractor hybrid powersystem with the extended-range fuel cell and the control method have the beneficial effects that the advantages that the fuel filling speed is high, and the endurance mileage is long are achieved; the system energy utilization rate is improved through internal combustion engine tail gas; and the power requirements of various operation working conditions of a tractor can be met through switching of all the modes.
