Pedal Power Mulcher


My family team created a pedal powered mulcher for the Innovate or Die contest.

The bicycle cranks are connected to a cutting drum that cuts, grinds, and feeds the material in. In the back is a, free-wheeling, cutting drum provides the opposing cutting edge.

Its purpose: To turn yard waste into mulch for landscaping and reduce the size of organic materials to speed up the process of composting.

The Consumers Guide to Effective Environmental Choices by The Union of Concerned Scientists lists 7 High-Impact Activities to avoid due to their "especially high environmental impact".

Pesticides and Fertilizers
Gasoline-powered yard equipment
Fireplaces and wood stoves
Recreational off-road driving
Hazardous cleaners and paints
Products made from endangered or threatened species
