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.
