This machine provides a mulcher and tumbler for use in optimizing the composting process. The drive shaft of the machine is connected to the rear sprocket of a bicycle which provides power from pedaling. The mulcher can be run independently from the tumbler to ensure the most efficient use of power when mulching. This machine can replace gas powered mulchers to curb energy usage, prevent organic waste from filling land fills, and provide very useful compost for landscaping and gardens.
