The extra spacers to close in the rear of the grapple or steel plate to seal it off from wayward limbs.
In my experience with mine, I've found that space has allowed relief for some branches to extend through the opening that might otherwise be pushed out when closing the jaws if that space were closed in. On the other side of the coin, sometimes I've had limbs "catch" and hang on when releasing the load. I don't ever remember having to get off to clear them, usually a drop and drag pulls it out. If you do close those spaces in, I can't imagine it being a great benefit, but it would decrease your ability to see what your doing at the business end.
