I'd scrutinize the clutch pedal(s): or whatever they're called when you have an HST! They are likely to have a switch/sensor that controls whether the range selector and diff lock (and more) are allowed to be operated. I don't think that fluid issue are going to keep one from being able to move the levers, I think it more likely that fluid-related issues would be that the tractor wouldn't move.
