Combines 6620 T2 Hydrostatic leak

One possible spot for the leak could be under neath the seat, where the lines go over to the cooler. hope this helps.

If you don't see any external leaks, check the oil level in your transmission. It is not uncommon for the hydro motor seal to leak. This oil will go into the 4 speed tranny. If so, while you are in there, be sure to check the condition of the coupler between the hydro and the tranny, best time to replace it.

Thanks Doc. I have emailed your response to my neighbor.
