Does anyone know what size nut the
middle hydraulic pump drain plug is.
The other two are 3/4 but using a
cresent wrench on the big middle one
but I can not get the nut loose. So
if I could find the right size I can
buy the right wrench for it. I looked
at my operation and maintenance manual
but still can't find nothing?

Do you have someone that can help you? If not you can use a block of wood and a jack to hold the wrench (preferably a pipe wrench in this case) up on the nut, then either whacking the wrench with a hammer or adding a pipe extension to the handle it will break loose. Remember that it is CCW looking at it from the bottom to loosen.

The big one is 1-1/16" I think. Thought the other two were 9/16" square...
