    Hi. I have a ferris w/b with a "yellow pull-up" type clutch. I thought it was called an electric pto, and it started the blades with magnets or something like that. (don't laugh, i'm stupid)

    Now, last fall I bought an older scag w/b in need of a new engine. It's got a manual clutch. Now I'm pretty damn sure that, because of that, I don't need an engine with a charging system, so I went ahead and ordered one without. But I'm confused, because, as far as I know, my ferris doesn't have a charging system, but I was pretty sure that it does have an electric clutch!

    So what the hell is a charging system, and how does it that all work with different kinds of clutches?

    Its using a magneta to provide electricity. All engines will have it, they supply the electricty for the coils to make a spark for the spark plugs

    grass cuttin fool is correct, you need it to supply electricity to the spark plug. even my trimmers have it and they have a centrafugal clutch.

    TClawn, grass cuttin fool, and seymour grass are need 'juice' on all the engines, and it's standard-built in.
    fixer67...nice illustration

    A recoil start w/o electric PTO wouldn't need a 'charging system'.

    To run powered accessories like, electric start, and especially an electric clutch (PTO).....more 'juice' is needed, and that's where a additional charging system is needed which may optional on some engine models.
