When shopping batteries it might pay to measure the actual tray width, depth and height available, then look at all the group options on a BCI chart. Most trays and universal hardware will work just fine with slightly larger or smaller batteries, unless you go nuts. For most tractors you are probably not using special clamps that clamp a ridge at the bottom of the battery case like many cars. For a 9N, you might have one of those fancy covers with a lid over the battery. When special hardware has to match up, group numbers are more important. When approximate size and terminal locations are the only issues, many other batteries will work just fine and some may be more popular/cheaper. In most cases, for tractors, I'm just looking for the same or a slightly smaller size, with plus and minus terminals in the right place. Reversed terminals can be more of a problem than it might seem. There are enough options with the right terminals to just avoid any problems reversed terminals may cause.
