The invention discloses a built-in motor type tractor drive axle which comprises an integrated shell, a drive motor is arranged in the integrated shell, and a main drive shaft is connected into the drive motor in an embedded mode. A first gear and a driving bevel gear are fixedly installed on the main driving shaft, a differential bridge is arranged in the integrated shell, the driving bevel gear is in power connection with the differential bridge, and the two output ends of the differential bridge penetrate through the outer wall of the integrated shell to be arranged on the two sides of the integrated shell in an overhanging mode. A front driving assembly and a rear driving assembly are arranged in an integrated shell, a first gear drives the front driving assembly and the rear driving assembly to rotate, and power output is achieved; a hanging assembly is arranged on the outer side of the integrated shell and used for hanging an operation component; and the motor controller is embedded in the electric drive axle. The drive axle is high in integration level, the motor is arranged in the integrated shell, the drive axle can adapt to the severe working environment, a complex variable transmission structure is omitted, control is easy and convenient, and the drive axle can be applied to different tractors and is good in universality.
