For the guy who wants to know the size of an acre; 1 chain[ 22 yards] x 10 chains  yards or any shape which gives 4840 square yards. Not yards square!!

Since that tractor was made before they used CCA ratings could it be possible that no such official rating exists?
How about you use what ever size battery that will fit? If I recall correctly it takes two on each side of the tractor and they are rather long, tall and skinny - so much so that no normal battery would ever replace them physically. I'm thinking electrically just about any pickup battery would be a good CCA equivalent. Provided you are paying attention to the 12/24 volt issue on those dual battery JD setups like the 4020 had. If you have two six volt batteries and they work as one 12 volt then you can't use 12 volt batteries for your pickup, in other words.
In the real world the actual difference between a 500 CCA battery and an 800 CCA battery would be hard to tell until the temp got down around 20 below zero. THEN you might get your money's worth, and you might not. In my opinion and with my budget I won't go with a high capacity battery - they just cost too much more. I also don't live in Alaska, so I don't have to worry about it often enough to be cost effective. I get my warm fuzzy feelings from somewhere else...
If you are having troubles starting with normal rated batteries, you won't escape the same problems with higher capacity batteries. The troubles just cost more.
