Oil & Fuel Oil Drain Plug Size on an L3940

[DannyInIllinois]

Can anyone tell me what wrench size fits the oil drain plug on an L3940? I'm doing my 1st oil change and the largest metric wrench I have is 19mm and that's too small. Thanks.

And a 20mm is slightly too large. I know from personal experience. Must be SAE. Try a crescent wrench. Worked for me.
