I was worried about not having a QA type bucket, but as I lay in bed last night thinking about this, I thought... I CAN MAKE A QA FOR IT. I will make a QA this summer when I get a set of used forks for it.
Yes, I know.. the 3130 HAS QA's, and more lift capacity... But the 3400 is already an upgrade to me over the JD 790 that I had my mind made up on in almost all ways. So in a way, just by going to a Kubota, I am already going with a bigger machine. (oh, and saving about $1000.00 too!)
