Here is what I found in my instruction book Page 1 and 2 are the capacities and are duplicated. Page 3 is the types. And page 4 is the how to on the transmission and hydraulic oils. Hope this helps Ya'll.
I can kinda picture what you are talking about, But still can't help with problem. I do know that the control knob that is in the middle is to control the speed that the 3 pt hitch lowers. See if the attachment helps.
