1966 1276 fluid leak

[Dconner 4]

My 66 1276 I recently purchased has a leak somewhere around the rear end. Looks like maybe somewhere around where it meets the frame at the front of it. Any ideas of where to look or what I could possibly search for first

Give it a good bath and get all the grease and crud off first off. Then park it over a piece of cardboard and see where it drips. It's much easier to pinpoint leaks if everthing is clean. Try and trace the drip out to where it my be coming from. Its possble a bolt that holds the frame to the transmission but unlikely. More than likely is around  a input shaft seal or the like. Change the oil in it, if you have a new to you tractor who knows when that was done last and if it's even the proper type. I've had a couple of leaks quit once I got the proper type fluid in it but than is kind of a long shot.

Was thinking bath also. It looks like it's up by the frame so I wondered that myself. I will do that and post as soon as I can with more thanks
