Hello, I am new to this so I apologize for the lack of knowledge, but that is why I am here!

I have a B7100 HST that has a fluid leak, it appears to maybe be coming from the hydraulic control lever (right side of seat) and it drips down around the right side of the rear diff. This makes it a bit hard to tell if the leak is coming from the hydraulics (control lever) or the trans (rear diff right side seal).

Im looking for some clarification on the following, is the hydraulic system separate from the trans fluid system? I know that the rear diff and trans are the same system and use the same fluid, same fill and drain plugs, does this also apply to the hydraulic system or does the hydraulic system have its own fill, drain plugs and filter?

Thank you for any help!
