Answer
The down under thing is cool.When you change the fluid in the final drive.Big plug in shaft side of final drive by back wheel.It goes in there.On the bottom of the same side right under the fill plug is drain look around you'll see it take it out measure the oil into a measuring cup.Put that much oil back in the big hole and a little more.Need more help later get on line.
