It didn't seem to me that there would be enough leverage introduced by the weight of the water given the length of the hammer arm and its mechanical advantage. Perhaps there's a hidden counterweight that I can't see.

Yes, that's how it works.  I have some photos of it moving, but they are
blurred ;-)  As soon as the bucket on the end fills up, the arm swings up,
then when the water spills out, the now heavier end with the pounder falls
back down into the bucket of rice pounding off the hulls.  It works all day
with no attention except to change the rice when it's finished.  Then they
throw the rice and chaff into the air and let the wind separate them.

I haven't been able to figure out how it's supposed to work.  I'd have
thought the water would fill a container, tip the hammer up, the water
would empty and let the hammer fall back down.  But I can't see that kind
of action happening with this apparatus.

PESO:

Many of the Hmong still use water to power various grinders and pounders.
Here is a rice huller in action:

C&C greatly appreciated.
