The invention discloses a brake resistor integration device and an electric tractor, the brake resistor integration device is used for absorbing redundant energy recovered in the whole vehicle braking process, and the brake resistor integration device comprises a support, at least one brake resistor and a cooling system; the brake resistors and the cooling system are fixed on the bracket; the cooling system comprises at least one radiator and at least one low-pressure fan; the radiator makes contact with the brake resistor and is located in an air blowing area of the low-voltage fan. According to the technical scheme, motor auxiliary braking can be carried out when the whole vehicle is in a full-power state, the safety and the driving mileage of the whole vehicle can be improved, meanwhile, the brake resistor integrated device has good heat dissipation capacity, the heat dissipation requirement of a high-power brake resistor can be met, and the service life of the brake resistor integrated device is prolonged. And therefore, redundant energy can be recycled in the braking process of the new energy commercial vehicle.
