[QUOTE="Earthwerks Unlimited, post: 10916, member: 1300"] Ken I have to differ with you on the QA design not withstanding upward pressure. I have a 20' boom attachment on my New Holland LS185.b that I can pick up (tilting back off the rear bumper) the entire machine off the ground with no problems. In fact the Owners Manual says do not bull doze forward with the bucket fully dumped but it's okay to backdrag, which puts a lot of pressure on it. I do agree that if the GA attachment's holes are substandardly out of shape, in the wrong position even slightly, or the steel used at that point is not up to par, then yes--you will lose it. Also, if the QA mounting plate's locking pins are not up to par and don't or can't keep the proper down pressure, then yes you'll lose it. But those issues don't fall abck to a faulty design IMO. With my background in product liablility (automotive), IMHO, not one skid steer would be in use if there were even a small chance that a customer could lose a bucket or attachment by applying downforce. Now, some quick attach excavator buckets are a different story---many workers (in trenches for example) have been killed by a QA bucket falling off as they were not properly installed. Subsequent systems have a backup lock of some sort [/QUOTE]
