I believe it is a live PTO. Only issue is I never really ran it like one. I always tried to start the PTO then get the JD into motion.

LouNy your reply really got me to thinking about just how the PTO clutch works in this old Deere. So much that I purchased the technical manual online.
After hauling 28 round bales through the Texas rain. I finally got a chance to look at the book.
For a few days now I have been looking at the parts list online and notice a "PTO Clutch" section which seemed to be internal to the transmission. Being the novice that I am I prayed that my tractor didn't work this way.
After reading the book I have come to the conclusion that yes the JD 1120 is an Independent PTO with an internal transmission power shaft clutch. I now believe I have to split the middle section of the tractor as well to replace the 6 to 8 pairs of disks and plates inside the PTO clutch. I have uploaded some material for you guys.
Yay more fun... I'm thinking should i change thread title.

A manual can be a good help for sure.
Does your manual give any directions for splitting and rejoining the splits.
Most independent PTO's that I worked on didn't require a split unless the drive hub had failed.
Good luck with your repairs

I believe that I have to remove the clutch or Bell housing from the transmission. The clutch should be just behind and below the on/off lever located between the two gear shifts.

Well today I got to put in some more time into the JD 1120. The clutch housing separation from the transmission went off without a hitch. Except for the mess of course, thank you family Dollar kitty litter.

I was able to split and remove the PTO clutch disks and pressure plates all 8 of them. Of course I posted some photos and am always happy to get any input you can provide.

Assuming you have the tractor manual, make sure you follow step by step when you put it back together!
I see so many things that need to go back together in the proper order.
No fun having to go back in.
