Abstract

A snow thrower is provided and includes: a snow removal system and a power system configured to drive the snow removal system to work. The power system includes a first motor. The snow removal system includes a transmission shaft, an auger assembly in transmission connection with the transmission shaft, and a snow throwing impeller mounted to the transmission shaft. An output shaft of the first motor is connected with the transmission shaft directly, so that when the first motor rotates, power is transmitted to the transmission shaft through the output shaft, so as to drive the auger assembly to rotate.
