bowhunter3030,
I've been using my extreme duty H&H toothbar since november on an 84" bucket attached to a Kubota M9000 and I love mine its first job was to help me move 1,000cu yds of hard packed dirt and rocks. I don't know if I'd have torn up the lead edge of my bucket or not but there is some security in knowing that I've added more beef up front rather than just the teeth attached to the bucket like most of the toothbars mount. I know there are a lot of folks using the other ones and only Henro and Aloha for sure have the H&H like mine and everyone swears by theirs and none indicated any lip damage when I was trying to decide which to buy. I have to believe that when you start prying stuff out of the ground a little extra metal up front won't be a disadvantage. I don't forsee ever taking mine off I just use the bottom of the bucket to smooth stuff with although that seems to be one of the selling points for all of the toothbar manufactures it looks to me like they ought to make a bucket for ag tractors with the teeth being integral with just the tips being changeable if you broke or bent one.
