Is that Y-shaped tree trunk meant to be there? It seems to me like it's just getting in the way of the press operating

I also fail to understand how such press might work, the counterweight seems to be working against the press purpose.

What do you mean? What counter weight even? The big block on the right where the man is, is the actual weight that causes the press to compress the olives.

That’s what I meant, the boulder is already at ground level so is not serving any purpose, the rope could be tied directly to the ground and it will have the same effect regarding the exerted force. It seems thy the guy is the one exerting force by mean of the trunk-pulley thing but it seems that a winch mechanism of some short would be better suited.

No idea, not an expert and maybe I’m not understanding it properly, it just looks counterintuitive to me.

The guy next to the boulder is rotating a log coiled in a rope. That forces the short log closer to the boulder, pulling the large lever down. It's levers on levers on levers. The whole system is quite clever.
