Export thread

Can someone tell me what head goes on this? And/or how to get this off? I need to clean it out and put a new head on it. (It didn't come in with a head on it)
It looks like one solid piece. I've tried quite a bit of pressure both reverse and standard thread rotation. But it won't budge.
The big one is fit's a 3/4 wrench and the small one fit's a 3/8.

I think I found it. Just not sure what to do with it. I don't have a head in stock that'll fit it. Even with the adapters that come with my heads.

I got it off. just had to put more pressure on it than i was comfortable with.

Do you know the designation of the left hand thread on that, please? I'm looking for a replacement nylok nut, if possible (my strimmer is an SRM250 but the head looks the same).

Sorry, I've forgotten all about this. I don't even remember working on it now.

And I'm not sure what you mean by designation. IIRC,

Designation as in M12 x 1.5 or M10 x 1.25, denoting the thread diameter and pitch. Thanks.
