Thanks, Joe. I've looked all over and can't find any parts breakdown for the hydro units themselves. Have found some other repair manuals on ebay for other hydro units. These are made by Eaton. I will explore the sticking valve idea, the cable and the levers it attaches to seem to be quite free.

click link below for diagram.

#26 is the lever on the transmission that lets the mower move. Appears to be on the bottom of the hydro trans. Might have bent it.

#40 is the cable that pulls that lever.

Make sure the E brake is off when trying to roll it. You might need to hold the trans release knob while rolling it. It might not hold itself.

They are two different hydro transmissions. From the diagram, I can only see one release lever but each trans might have a release lever on it.

I appreciate the suggestions and taking the time to hunt for the diagrams etc. What it turns out is, there is a lever on each Hydro unit that releases the hydraulic pressure; they are linked to a common release cable. All of that is undamaged and free. The levers each bear on a sort of rod that goes into the case and apparently press on a valve inside. Those rods don't pop out like they should, and yet, they don't appear to be frozen. So either something inside isn't moving like it should to pop them out, or--maybe--there's not enough oil in the case anymore to develop the hydraulic pressure to move them. It seems to be impossible to add oil, at least, the manual says to take it to a dealer. That may turn out to be all I can do.
