L3400HST oil drain plug size.

[swampvol]

Needing to change the oil in the old '3400 tomorrow and need to know the drain plug size so I can pick up a couple of gaskets. The tractor is at my property 30 miles away, and while I think I have some spare crush washers there, I don't want to take the chance.

Thanks guys.

Edit: It's a 2006 btw.

Ive never replaced the washers on my 2005 L3400 HST and never had a trace of oil.

That should be easy look up at your dealer.
