Here’s an oldie, but goodie, make your own generator – “The key to this design is that it will require a horizontal shaft motor, which can be found on old drum style lawnmowers, roto-tillers, and lawn edgers. The most common motor size you will find on the used market will be a 3 or 3.5 horse power model. Larger motors are harder to find because most of them are snapped up for building go-carts or mini bikes. “ [via] – Link.

I had seen some similar plans for these homemade generators before, including ones made from modern vertical shaft lawn mower motors. This company actually sells a premade bracket for this purpose. here’s a link for that:

While I was trying to find the plans described above, I stumbled on another set of plans where you use the old lawn mower as a cart for the new generator. i have to say the alternator mounting brackets on this design look a little sketchy, but the basic concept is pretty ingenious. here’s a link to that:
