My first Kubota I bought the Kubota tooth bar for my tractor. It cost me over $300. They worked really well and I was pleased with them, but then when I traded that tractor in, I bought a tooth bar from vevor for my new tractor and I can't believe now how disappointed in that first tooth bar I am. I guess I wasn't disappointed before, because I had nothing to compare them to. Vevor tooth bar was twice as thick, came with removable/replaceable tooth covers and half the price. Vevor never disappoints.
