Not sure what version of the bucket I have. Purchased March '2006. But, it's bolt on. I have no problem lifting a heaped bucket of wet clay, or an over flowing buck (way out on the toothbar teeth) load of granite rip-rap (I should have taken photos of that). Break out force is where it could use a little more umph. Gotta finesse it into a pile, especially with a tooth bar. And the loader is not much for digging like a skid steer is. Not sure, but I think the combination of bucket shape and curved loader arms reduces it's effectiveness for this task - front end just rides up off the ground onto the bucket arms. But then, a loader isn't supposed to be used to dig anyway. Still, for this size tractor the new style loader works great. I wonder how much power is lost with the QA configuration?
Rick, from the photos the sides just looked thin. Probably the angle. The bevel also probably makes them look thin. I'd still like a QA. Just hard to justify the expense after the fact.
