Abstract
A walk behind self-propelled crawler snowplow includes a snowplow mechanism driven by an engine via a belt drive power transmission mechanism, and an overload protection device associated with the belt drive power transmission mechanism for protecting the engine against overload. The overload protection device comprises a tension sensor for detecting the tension in an endless belt and generating an electric overload signal to disengage an electromagnetic clutch in the belt drive power transmission mechanism when a belt tension greater than a predetermined value is detected.
