I have scrapped a few like that myself. I just left it on there, since it was an original part of the machine. Not any different than scrapping a refrigerator and not taking the insulation out or all the plastic, it is all a part of the original equipment. Now I would not load busted concrete in one that it did not come with, but neither do I remove from one that it was originally installed with. Have not had any issue with either of the yards I frequent.
