1243 production began for the 1981 model year with the intro of the 225 hp 8820. Sorry, can't help with the rest. Glad to hear your combo is working well for you, many of the red-rotor fans swear that a conventional machine won't handle 12 rows of corn.
9600, 1243 corn head and final drives
I bought a 1243 corn head this fall and other than buying new lift cylinders, got along good. I am now reading that I am supposed to have the Planetary Final Drives if I use a 12 row head. Even though my combine was setup as a corn machine from the factory, I think I have the standard final drives. I know some people will push equipment to the limits, but I was wondering if I need to be legitimately concerned about final drive damage, or if I will get along fine? Also wondering about not having the high torque hydrostat unit for twelve row heads? My info is coming from 9610 material, but I believe it is accurate to my 1994 9600 as well.
Don't know that it will matter but I only pick about 300 - 500 acres a year which is probably not much.
Also, far back does production on 1243's go back to. I assume the mid 80's or whenever they started making a 40 series corn head?
Thanks for any help.

If yo got along ok I wouldn't be too worried about it.
If you are on fairly flat land the std hydro system will work and if you don't have a huge bin extension and your drive wheels don't have a bunch of offset then the single reduction units will be fine
The option for the planteary finals included the larger cylinders, hydraulic pump and 105cc hydrostatic system.

there was a guy in the tex panhandle when i was there that picked 4000 acres of irrigated corn with a 9600 and a 12 row. he had no problems at all.

At the 12 year mark I lost both final drives on my 9600. It never carried anything heavier than a 25 ft. rigid, never extensions, but did have floater tires. The outside bearings failed.
At some point, JD changed the grease frequency on the outboard bearings on the final drives (IIRC) from 500 hours to 100 hours. So keep your final drives greased.
I would be more worried about the variable speed feeder house drive being able to supply enough power. I wouldn't recommend chopping rolls.
