Self-propelled snow blowers

Self-propelled design

— snow blowers driven by an engine on wheels and capable of moving independently during operation, without effort from the operator. This provides additional convenience; on the other hand, self-propelled models require more powerful engines than non-self-propelled ones, since some of the power in them is spent on movement. Therefore, this feature is found mainly in heavy models with gasoline engines: it would be difficult to move such units manually, and the necessary power reserve can be easily provided in the engine.
