All,
I contacted the dealer again after hearing from Mike and others that they experienced the corrosion problem even with the "new" battery that Deere is now installing on hydro CUTs as a solution. Apparently, Deere is now standing firm that the new battery with the individual screw-in caps has resolved the gas problem. Therefore, until I can actually show damage on my new 4310, the dealer is not willing to take back the existing battery and offer me a credit based soley upon information I have received from folks on TBN. Either I wait and see or simply eat the entire cost of purchasing an Optima and use the existing JD battery as a door stop.
