If your oil carries a C-4 rating,I think it is as close as you are going to get Dexron. C-4, is a heavier oil, less foaming and can handle higher temperatures then Dexron from what I can recall. And maybe, just maybe Simplicity is saying OK to Dexron and Mercon, it can be purchased anywhere, even though they would like you to use their product. Another thing to remember is the hydros in garden tractors do not nearly get the work out as do your combines and skid steers.

      folowing  this from a link at the downloads.  I just rescued an AC 920 with the lambodini diesel. I can' t download  yet .  Where did you find the PDF copy you posted. . I would like to figure out how to adjust the injection pump. 
      I assume it's a bosche, correct

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
