Just did a cover repair on the 861. Very similar to what you have.
Can you get the draft rod out without removing the rock shaft? The answer is yes, but it will be easier with everything disconnected and removed (cylinder, control linkage) I had a worn cam pin on mine, so needed to get it all out.manyway. To get it put you need to twist it and have the rocker in a certain position.
You might try taking the bolt off one end and seeing if you can slide the arm off and push the rockshaft and remaining arm out the other side. I was surprised when I was able to get mine out with a little light tapping from a 5 lb hammer. You don't want to get crazy and beat on it or press it out as you can crack the cover. Then you are up s$&? Creek. That would solve your problem and it is easy to do.
Check to see if your cam pin is worn. Good time to R&R that.
I recommend the cover gasket from CNH, as well as the piston o ring and backup ring. They are higher quality than Tisco. Get a cover overhaul kit (probably Tisco...ok) also, the you get all the o rings.
It is an easy job. Now that you have it off.
I would also make some guide pins out of grade 2 bolts (cut heads off) as it makes lining up the gasket way easy whe replacing the cover.
Clean the gasket surface on both the cover and housing and USE NO GOOP/GLUE/SEALER, etc... When replacing the cover. Just the gasket. That is where the guide pins hold the gasket in place and let you slip the cover down. I guess you can use sealer if you want to swear a lot next time... ;)

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
