Oil & Fuel Trans drain plug locations- L4330HST

[Old Corps]

I've looked under my Kubota for the 4 trans drain locations, following the diagram in the Op Manual. Diagram shows two bolt-head plugs, I only see the one towards the rear. There's the clutch housing drain bolt with the pin, but that's all I see. Are the other drains internal hex plugs? I don't want to start unscrewing plugs willy-nilly. I'm missing something in my comprehension, I guess. Any clues would be helpful - thanks.

Mine are 2 19mm I think under the transmission and hydro case in the center and one at each rear axle.
