I love my Power Reverser; I have often wondered about how the learning curve would be with the newer hydro tractors, I understand they have come a long way. I think the biggest problem I would have would be if they are the same as operating a Skid Loader, i.e. the engine speed needs to be high to get the response, and if you get in a bind, you have to ease up on the pedal to get the torque in the machine. I have been used to getting more power from anything with a motor by giving more pedal (or a twist of the throttle) for far too many years to make the change; I have used a zero turn mower for years, and still have to remind myself on hills in heavy cutting to pull back on the handles!
