Pedal Powered Compost Turner

Using materials and bicycle parts all found in the garbage, we have built a pedal-powered compost turner. Composting is perhaps the best way to reduce household waste. While harnessing the mechanical power of the pedals and cranks, a person is able to turn up to 500 pounds of compost with minimal effort using this pedal powered compost turner.

That's a huge compost bin. You guys must eat well! Love the shot of the gear reduction system. I also like how the frame floats about 4 feet about the ground, kind of like a tall bike. Funny ending too. Nice submission!

this large bin is actually moving to a local community garden to be used by everyone in the neighborhood. Approximately 150 people use the space and contribute to the composting.

You gotta put a windmill on that !

Freakin' BRILLIANT!

Howdy--do you have access to the blueprints? I convinced the non-profit I work for to build one!!! Please shoot me some advice...

Best, Max

Could a soil tromell/screener be made out of a washing machine/dryer's barrel and another circular mesh around it? That would also be useful if pedal powered.

Legs are easier to use than hands.

So cool. And, a very good workout too.

Actually, I can build one, now that I understand gear reduction, torque is inversely proportionate to the reduction. Here it looks like they have a 4 stage gear reduction system. Also, it looks like they have not done any welding, which makes it a bit easier, just need several throw away bikes.

you can adapt it to make a pedal powered washing machine, I want the plans!!!

Having built a pedal powered sewing machine, I can certainly appreciate the engineering and effort that went into this, but is it really necessary? How often would the compost need to be turned and for how long? Seems to me that a simpler hand crank system would serve the purpose.
