The only useful part is the very end, I would expect the engine to rev back up and then quiet down at the higher no load speed if the engine was bogging down. I don't THINK I heard that.

Usually valve handles should be parallel to be open. Perpendicular to valve to be closed.

It would seem to me that if a drive motor was going out, you would really have to fight the machine to keep it from favoring the weak side while it is in travel. If it is doing that than the drive could be bad. It would be interesting to hook up a hydraulic attachment, like a rock rake , street sweeper or something similar with an orbital motor and see if it has the hyd. power to run it.

But how are the pumps setup on this machine? The drives could have a separate dedicated pump.

I was going to say that is just how they behave on grades until I watched the video. That grade doesn't appear very steep.
I cut in the road on my new land last year, at the peak was 14% grade. I definitely was losing speed on that grade. Brought a case dozer out to cut to a more acceptable peak of about 8% at its worst transition. The dozer would track up it fine with zero hesitation. But my c238 still does not love the high grade with a full bucket. But the dozer and skid steer are nowhere near the same function.
Your machine and mine are about the same hours, I've got a little more. But your grade looks less. If I were you, start saving for parts and see what the flow rates are. Granted your machine is for making money, mine is for personal use. But 3000 hrs +, have to be realistic with expectations

You said the hydraulic flow was good. What about the pressure? Also will the machine switch from low to high speed? Assuming both speeds work try low speed at 3/4 to full throttle have the arms down and push into a non movable object such as a large tree. See if both tracks spin. Whats the condition of the rollers and idlers. Lift the machine off the ground and with the tracks sagging are the rollers free, loose or seized?
