You want to mulch! But you hate the stinky smell of gas, and what you have handy is old and questionable. Maybe electric mulcher? But they are so puny and cannot handle the serious mulching you have in mind. I suspect it requires a gas engine to provide the torque needed for anything more robust than twigs and leaves.

The flywheel pedal mulcher is perfect for those who wish to forgo engines and motors. Load the flywheel frame with bricks and balance with sand added to integral sand cups. Now that it is good and heavy, get that teenager to hop on and spin it up. Put your back into it now, tats-boy!

Once the flywheel is spinning, engage the clutch and mulch, mulch, mulch.

The flywheel pedal mulcher can easily be hooked to a waterwheel for when the tattooed ones are freshening up their tats.

The worrying truth is that this would probably work.

I'd recommend changeable gear ratios to get the flywheel up to speed. The energy stored goes up with the square of the velocity, so faster is gooder, and a ratio that will give speed will be too tall to get things started.

"...engage the clutch?" You mean Tats-Boy has to both pedal AND feed brush into the hopper? You're a taskmaster.

Once he gets the flywheel up to speed Tatsy can jump off the bike and work the hopper side of things. So yes, but one thing at a time.

Good and heavy teenagers willing to spin flywheels are hard to come by these days. Usually they're either good and heavy, or willing to pedal, but not both.
