The invention relates to a wheel edge driving system and an electric tractor, and belongs to the technical field of electric tractors. The wheel-side driving system comprises a motor and a wheel-side speed reducer, the wheel-side speed reducer comprises a clutch, a brake, a first-stage planetary gear mechanism, a second-stage planetary gear mechanism and an output shaft, the output shaft of the motor is connected with a first sun gear input shaft, the first sun gear input shaft is connected with a first sun gear, and the first sun gear is externally meshed with three first planetary gears; three first planet gears are internally meshed with the first inner gear ring respectively, one end of a first planet carrier is connected with the first planet gears, the other end of the first planet carrier is fixedly connected with a second sun gear input shaft, a second planet carrier is fixedly connected with an output shaft, and the output shaft transmits power to wheels; an inner friction plate and a steel sheet of the clutch are respectively matched with the first sun gear input shaft and the first inner gear ring; and an inner friction plate and a steel sheet of the brake are respectively matched with the shell and the first inner gear ring. The clutch and the brake are controlled to be combined and separated so as to carry out gear shifting and speed regulation.
