Abstract
A walking-type snow removal machine comprises a snow removing member provided at a front part of a body frame for pushing snow forward, and crawler belts provided on right and left sides of the body frame. The body frame carries thereon an electric motor and a battery. The electric motor drives right and left drive wheels to drive the crawler belts. The electric motor generates little noise as compared with an engine, and contributes to downsizing of the snow removal machine. The battery supplies electrical power to the electric motor.
