My old 180 has started putting hydraulic oil in the rear so I've read to connect the drain outlets of the hydraulic and the rear together.Problem I'm having is finding a fitting that will
match up with the threads of the hole in the rear.Anyone know what I need?

Gary - drill and tap your existing pugs to take common pipe fittings then buy plugs when you split it later to fix it right.

Was hoping I could find something to screw up into the rear hole, the front plug is pipe threads.Doubt I'll ever fix this tractor the transmission has problems and is pretty rough but still runs good and all I do with it is load and unload hay bales,plus being a gasser it starts easy in cold weather.

i had to get a plug from AGCO i think the plug was about $25. take your existing plug out and drill through the plug tap the hole with 1/4' pipe thread and use a close couple fitting in it. puit a 1/4' to 1/2' bushing on the close couple nipple before putting you elbow on. using a smaller elbow restricts the fluid to much. you wont have any pressure in this line just gravity flow to get the fluid to transfer.
