Somewhere on the left side obviously. I don't have much in the way of books for this combine because they are so danged expensive. Looks like it is NOT coming from the reservoir. Also looks like...and I am guessing...there are two pumps? There is what appears to be a smallish pump forward of the engine. It shows no leaking. The leaks appear to be from the ???? that is directly at the rear of the engine where the tranny would be if it were a car. Many hoses coming from this and I am assuming this is the hydrostatic drive. I have done a lot of cleaning in the area as the fluid has dripped onto hoses and then run down the hoses and dripped onto other places. Hoping it is just a hose but are there any special places I should look? Otherwise I will just stay the course.
 
I have seen some leaking from the servos that control the direction of travel, I think that is what they do. two round things that stick out of the hydro pump, about 3 in in diameter.
