    Have tried twice to get the right size to loosen oil drain bolt but can not find the right size. Does anyone know what size of wrench the oil drain bolt on a briggs 24 hp engine on a Scag zero might be.(had to just drain oil through filter) Let me first say i have a 200 piece tool kit in truck and nothing fits starting to think that it needs to be a wrench but there is not much clearance to use wrench.
    Will be getting model number and contacting briggs tommorrow.

    I've tried standard and metric. After wenching on cars,motorcyles,lawn equipment this is the worst bolt that i have come across, and it is not stripped. Just can't find the size.

    Um..

    Adjustable wrench?

    One of your wrenches has GOT to fit it. Either that or it's partially rounded off.

    Yes, maybe I can use a 3-4 in. in length adjustable wrench. Last resort, just have to dig it up.

    Maybe 5/8's..... At Wal-Mart they sell this socket with a series of metal rods in it that form around a bolt/nut. You may have to use a rubber mallet or cheater on the wrench, but it will come off.

    Maybe it's one of those "b@stard" sizes. Sears catalog, 1/2 drive lists both a 19/32 and a 21/32 socket.

    Please let us know when you find out.
