ABSTRACT:
A pair of counter-wound spring-like members are placed in a gutter above an opening communicating with a downspout. A cord joined to the spring-like members extends through said downspout and out of an opening in the downspout. The cord is pulled and released to contract and expand the spring-like members to grind and/or crush debris collected in the gutter.
