Rob-D, my new battery is in fact sealed or at least it appears to be. Thankfully it's not the same design as the original version. I had to wait about 30 minutes or so at the dealer as they did not have any prepared. I think they ship them dry and then the dealers have to prepare them so at least I got a fresh one.
I'm glad to hear your machine came with the new design. I'm sure Deere has recognized the issue and since corrected it which is nice to see.
BTW - Congratulations on your new machine. I seen your previous post and of course the pictures and it looks great. I really like the hoe and the thumb. Sometimes I regret not getting the hoe with mine. I was pretty much over that until I seen yours with the hoe on it. Have fun with the new machine.
Thanks!
