TN70A drain plugs x 2 first plug

[Doc_Bob]

Here (in sequence) are two pictures showing a drain plug on the main gear box and one (the second pic posted) that is a drain plug on the PTO gear box. I assume I need to remove both to drain all of the hydraulic fluid????? Any other plugs?

Any help appreciated.
