Unless you really want to make alcohol find out what voltage the mower runs on and get a small 2nd battery. Then you can get some extra cable and a switch mount the 2nd battery run the cables to the switch then back to the original power connection. You now have a reserve battery that is there when you need it just by flipping a switch.

Any thoughts on using the grass clippings in a gasifier verses a distillery? I've seen cars that run off of a gasifier, now that was charcoal or wood (biomass) But would grass be enough fuel to gasify and run a Mower motor? Better yet could a gasifier be minimized enough to fit on a mower?

I think this is a matter of convenience and hitching, if the first lawnmower was from EGO, then the likelihood that you will use this brand is even higher, given that in fact, all these brands are not so different, everyone has Both successful and unsuccessful models.

Get a pet rabbit, feed it that grass, and use a biodigester to process its excrements into biogas and fertilizer. Maybe you could take a look at those "gas bag" systems that were used there in Europe and in China with coal gas as an alternate fuel when gasoline had been rationed during WW2.

Back up and consider the ecology of ground cover. What gases are given off by decaying plants? How best to use the heat of decomposition? My yard is small enough that an electric mower that mulches is satisfactory. Consider running a bio-diesel commercial mower if you have a large area. I am looking at what plants in an expanded garden might be better.

would it be possible to make ethanol from grass?

when i bought my house it came with a nice electric lawnmower, wich unfortunately since we increased the size of our lawn, is no longer big enough.
You could, the question is whether you should. That hinges on how big the lawn actually is (acres? hectares?) and why the electric mower is no longer big enough.



I'm hoping it just needs a longer extension cord. No? deck width? Battery capacity?

It is not a new idea; traditionally, the seeds of grass like barley are malted and used to make beer. In that sense, my pusher mower has run on fermented grass more or less successfully; only the grass used to power the mower did not come from my own lawn but the fridge.

I admire the idea, but it cannot be worth the cost or effort. It would be so much easier to just buy fuel or an extension cord.
In my case, if I were fed my own grass I might well refuse to push my pusher mower over the lawn.

But that's me. Not everybody would turn down a batch of fresh grass.
Here's another approach to the problem.

Feed your mower grass directly - it mows by getting fed.
Free fertilizer to boot.
