You already have a walk behind lawn mower, don't you? Rig a V belt
pulley on the engine shaft and a piece of angle iron to mount a junk
yard alternator, one or two 12 Volt batteries and an Inverter.You can
have 12 Volt D C power and 115 Volts A C power.Some walk behind lawn
mowers have a 6.5 horsepower engine.I have one, actually I have two walk
behind lawn mowers.That damn ethanol gas screwed one of them up, I will
fix it someday.Winter time is a good time to check the pawn shops for a
good used walk behind lawn mower.
