:thumbsup:Good for you Guy, for recognising the thread title might have been a bit harsh.
I would not worry too much about the battery or damage. But I realise I don't have a huge concern about the aesthetics of my equipment and vehicles. I keep them maintained but accept the imperfections that come through use. I do think the dealer should have at least offered some kind of assistance to repair the damage to your tray, even if it was just some free paint for you to do it yourself.
I recently punctured my battery and damaged the battery tray. I cleaned it up and replaced it with the same brand (Interstate) after researching online. I see others have said good things about Interstate. If the voltage checks others mentioned turn out OK, perhaps you just got a battery lemon or someone(most likely the dealer) damaged it when they installed it.
Your dealer's uncaring attitude certainly unfortunate. Hopefully he was just having a bad day. My dealer experience is just the opposite. I bent my top link (through improper use) shortly after getting my tractor. I took it to the dealer and he straightened it as I waited(including repairing the threads) for no charge.
This may be a bit off-topic but....it is important to take the little maintenance items such as checking for loose bolts seriously. I find the small bolts holding the pivot pins on my DK35's loader have a tendency to loosen. I lost one(luckily the large pin stayed it) and find one or two slightly loose when checking them. I just tightened a couple last week and will reinstall all of them with blue LocTite.
Kioti's are good tractors and chances are it will give you mostly trouble-free service. Hopefully your dealer will do the same.
Cheers
ADDITION TO ORIGINAL POST:
Adding this after seeing photos on my PC (they did not display on my Android). The damage is much more severe than I originally imagined and can relate to your original concern. Your dealer should have been much more helpful in cleaning it up. The problem is the dealer, not the tractor.
I also see your battery is not an Interstate. Mine came with an Interstate and I think all Kioti's here (at least at my dealer) have that brand. That is what my dealer sells as replacements. Perhaps your dealer put in an old or damaged battery.
