Although my first 4400 was a POS /forums/images/graemlins/mad.gif, my current 4400 has been a gem /forums/images/graemlins/laugh.gif and its warranty expired three months ago. I service the battery every couple of months (replace anticorrosion discs twice a year, clean terminals, remove any corrosion, add distilled water if necessary, etc.) but noticed after the inactivity during the winter that I had a tennis ball-sized ball of white corrosion fuzz on top of the positive terminal/connector that also leaked down onto the area beneath the battery as well as getting into the transmission cooler. It also ate through the positive cable next to the connector. Instead of asking the dealer to come and get the tractor for this issue, I powerwashed the whole area and serviced the battery, used much baking soda to neutralize the acid, powerwashed again and painted some of the corroded areas and installed a generic auto battery cable connector. Two months later and out of tractor warranty, the terminal was corroded again. I replaced the battery and stopped by the service dept. to question them about JD (possibly) helping with the transmission cooler since the corrosion damage occured while under warranty even though it was not reported and I was concerned about potential future trans. cooler leakage and was told that there is a "Fix as Fails" issue here and that JD will supply all parts and labor to repair this issue, including new battery, positive cable, transmission cooler and what else I do not remember. This is even though my warranty had expired. My goal in providing this info is to advise anyone whose JD tractors fall under this Fix as Fails issue have until December to get it fixed according to the service manager. Although I felt that with the baking soda packed into the transmission cooler to neutralize the corrosion and then powerwashing it, it would be OK, the service manager indicated that eventually the trans. cooler will still fail and that is expensive. Owners of 4300's, 4400's and which other models I do not know, should check their battery terminals periodically and get the issue resolved if there is one, before the deadline. If this helps one person, it was worth wasting space on the tractorbynet hard drive. Michael S.
