Pedal Power Mulcher

[selsigpoeth]

This could be useful to break up small twigs as you show but also to break up old food eg. carrots potatoes for composting. But would require a better stand, hopper, larger capacity and gearing. Would definitely buy one then.

[egnurevets]

Seems like a great first step! I'd love to see larger capacity (bigger blades and hole), chain drive with derailleur for variable speed/torque, and a flywheel to supplement cutting force. Maybe also a hopper and a higher drop, to increase capacity. Then you'd have a seriously marketable product. Wish I could do it: but I'm a writer, not an engineer.

great idea!!!! more gas for me.

[Lucas166537]

In honor of this video, I put a gasoline engine on my execise bike.

[phdharok]

what did you use as the blade? I definitely want to build one of these

[NOLIMIT69NOLIMIT2000]

Yep I feel the need to go out and fire up the gas one. This video made me feel a bit femonon.

[iy9g86]

It is elegantly simple and I just happen to be looking for such a device. No bio-mass leaves my property; it all goes back to the soil. I am not keen on small engine powered products in general.

So I would like to build one.

I was wondering what you used as the cutting blades, something off the shelf??

[HDFoxra]

lol um, only problem i see here is that you can't really do any real yard work with this.. i mean, ok i can put one or two little tiny branches into a small hole and get a tiny pile of scraps... and on a larger scale, all your "efficiency" goes away because you'd have to convert your pedaling through gear boxes so you can actually turn the larger blades to chop bigger things, thus lowering the actual speed of the blades, and thus its effectiveness diminishes.

[hootergirlsrhot]

you should sell that, i would buy it

[thomasuras]

nothing like getting smacked in the nutz of face with a stick wile your mulching

[1crazyfocker]

great work

[Chipotleaway]

wow that is pointless who is actually going to sit there and feed one little stick at a time WTF!!!

[battlehappy]

I know right? Why would you want to do any exercise when you could sit on your ass and criticize anonymous strangers?

[jigglesnap]

This isn't going to have any effect on the environment whatsoever.

[terve41]

That thing is direct-drive and geared too low to really chop up the big stuff...you need to incorporate the deraillier and bike chain too! Then you'd have a range of gears, and variable chopping power to service that guy in Riverside.

[mandojb]

Can you make one that cuts smaller?

[jmmgarza]

Good luck. Come on over to my house (Riverside, CA) and use that puny contraption. You better have something that cuts 4 inch and larger branches and a lot of them. Lance Armstrong would quickly tire after using your pedal powered mulcher.

[Carlstens]

jmmgarza,

Look around you... the economy is about to collapse!!! Use that 4 inch stuff to burn & heat your home! Shred the smaller stuff to run a wood gas generator (Just google it). Grow your own food, learn how to store it. make your own electricity, collect rain water. Look... Your going to have to know this stuff, or die soon. 5 stars, and favorited!!!

[MissQuilly]

You really need to patent this! I love it! I would buy one if you would sell it! Or if you could sell the instructions on how to make one! Helping the environment, good for my garden, good for burning calories....I want one!!!! Please!

[nicecollarproduction]

This is great. Thank you very much for this. I don't like that the people are saying, do this do that, you should make it bigger. I admire that you started this. I'm going to make one myself. Thank you!

[TogieTung]

Its more efficient if someone design a rowing machine version where the user pull a steel cable turning a big flywheel/ cutter disc & shred that garden waste to bits..& you can have a full body workout to boot...

[CydeSwype]

where'd you find the drum cutter? i want to build one of these but having a hard time sourcing the parts.

[SteveOSpielberg]

peddeling gives you a Hernia !!!!!!!!

[hiramcook]

Have you ever seen mulch? This output looks more like broken twigs.

[pizzap66]

watch your fingers!!!

[warrengraham]

Use a flywheel as htzland said, and dslunsfor1's problem about how big it can do, will be partially answered. Also, please make these plans public, I know where the great benefit of this will come. Rural biogas maceration for increased yields of domestic natural gas fuel.

[hitzland]

Great idea.

I would add a large fly wheel to increase the crunch power, improve on the feeder shoot and over all cleaning accessibility of the design.

Than test it on sunflower, kale and tomato stalks etc. in other words the nasty stuff. I run a small family garden and would buy a working pedal chipper in an instant.

[dslunsford1]

Looks cool! I'd like to see one of these in a slightly bigger form, since i just compost them if they're as small as the ones you're using. At what diameter do the branches start to make the chipper seize up?
