It’s not enough to move wet leaves off new grass, or maple helicopter seeds out of established grass. You know how I know? Because I’ve got one of the top-spec gas blowers and it often takes 4 or more passes to move these items. And I’ve tried 4 different electric ones, none of which came close to working on those two tasks.

Once they work equivalently, I’ll be happy to give up the maintenance and hassle of small gas engines.

If you're ok with a cord, I'll build you one. Otherwise, I can also build you one with a backpack mounted battery. It will be pretty expensive, though.

The corded ones are an utter joke. (12A at 120V is only 2 horsepower before considering losses.) That’s the one I have occasionally dusting the floor on a warehouse type building now. My gas blower is ~6HP and it’s one model down from the largest I think. I won't have an L6-30 handy for you to use as the supply for a corded model...

A backpack battery model would be preferable anyway; I’m already wearing a 79.9 cm^2 engine, fuel tank, and blower on my back now. No one’s going to carry this as a handheld; all the large ones are already wearable for convenience.

Sure, that sounds doable. How long does the runtime need to be?

[sokoloff]

For me, an hour of runtime would do (once the battery was 4 years old).

For it to be a commercial success, I think you’d have to be able to run 5 hours in a day (but not all at once and battery swapping/charging on the truck from 12V would be okay).
