The skeleton rock bucket is beefy but flawed. The front teeth curve upwards on the bottom, and the mounts extend well below the cutter bar. When trying to remove debris from a hard surface (rockfall from a slope above a long driveway) the bucket "rides up" and collects no material unless I can dig into loose debris that is fairly deep. The cutter bar never engages the hard surface. Tilting the bucket forward LIFTS the cutter on the teeth, while the teeth do not dig in because they're shaped like the prow of a boat. Bummer. Customer support told me to file a warranty claim and ended the conversation when I asked how to perform this basic task. I'm left trying to find a fabricator to cut off or grind down the mounts. Also, the quick attach openings are too far apart, jamming the pins on my TYM T25 tractor. When I asked for the spec on those openings, to find out if my bucket is defective, I received no reply. My Titan box blade, which came with the tractor, is great!
