ABSTRACT:
A combined mechanical and electrical control for the traction drive and collector-impeller drive of a snowblower is provided which operates to disconnect the traction drive when the operator loosens his grip on a traction drive control lever to an extreme drive-disengage position to which it is constantly biased. Further, the control operates to stop the engine in the event that the operator loosens his grip on the level when the collector-impeller drive is engaged. However, the control is arranged such that the operator may manually hold the traction drive control lever in an intermediate drive-disengage position, while leaving the collector-impeller drive engaged without the engine stopping.
