    Default Oil drain plug size?

    Can someone tell me what size threads the motor oil drain plugs are on L3x30 tractors?

    I want to pick up a couple of seal washers prior to the next oil change. I am probably going to switch from what looks like copper washers to ones with rubber o-rings built in. Currently there is a slow drip from one of them and retorquing didn't stop it.

    FYI I looked up the parts on several websites and none of them gave the thread sizes.

    Good information to know, I haven't had any leaks with mine, but now I know what to do if I do.

    By any chance would the M12X1.25 be the same size for a B3200?
