I'm still running the stock battery in my 2320 but I check it often and carefully pressure wash around it when I clean my tractor. It seems to be ok so far with about 8 mos. and 40+ hours on my tractor.

This thread lives - cool.
Coming up on 10 months of having the battery installed and it has done an amazing job for me and the corrosion problem is LONG gone. Still happy with my 51 Optima Yellowtop. It has worked excellent in both the winter and now summer with running the extra lights on the ROP and also running my Femco sprayer setup.

These battery sizes, 22NF are not hard to find but are classified as specialty sized battery for a number of uses such as solar, UPS, wheel chair, golf cart, lawn tractor, etc. Finding one suitable for a diesel engined tractor is much harder as the CCA just isn't there. I've seen them as low as 72cca with 390 common but less than the OEM battery. Some don't even have a cca rating but offer only a reserve capacity. Group 51 sized batteries are no better (slightly smaller than 22nf, although similar to the extent that I think they might be interchangeable).
By far, the best spec'd 22nf AGM gel battery out there that I've seen in a short time searching is this one:
Adventure Power UB12550 (Group 22NF) Battery - Group 30H Batteries
This battery is a marine usage battery but no different than a yellow top battery, I suppose. However, it has 670 CCA and the description says it can be mounted upside down without leaks, resists shock and vibration and no gassing during charging... Sounds like the way to go. For $150.95, it's not cheap but as hard as they are to find, free shipping (heavy), and the upgraded specs suggests that it's probably worth it.
Perhaps someone here might be the guinea pig and try one?

No, it specs as well or better. The 670CCA advertised for this battery compares nicely with original equipment spec of 500CCA. It appears that Exide also offers a 22nf battery (ES22NFX) in their Extreme Cycle Duty line of batteries. The CCA advertised for this battery is 550 CCA.
As far as physical size is concerned, for all practical purposes, I believe the size difference between the group 51 and 22nf is negligible and should be interchangeable.
22NF 9 7/16 (L) 5 1/2 (W) 8 15/16 (H)
51 9 3/8 (L) 5 1/16 (W) 8 13/16 (H)
As you can see, the group 51 battery is just slightly smaller. Perhaps the new tractors are being delivered with 22nf battery? The group 51 battery does not spec higher or better than 22nf. A 51 should drop right in for an original 22nf application. The other way around might need some measuring first. The differences, although slight, could be just enough to not work however frankly I really don't see that happening or being an issue.
The only question mark of whether this, or any other battery will work with your tractor is in the area of mounting accommodations. The original battery has a lip at the bottom to accommodate a clamp/bracket. If this is not present, then an alternate hold down might need to be fabricated but I sincerely believe this to be an area well within the ability of most TBN'ers.
I hope I've addressed your question correctly.
