Can you back drag, or back rake effectively with a dual hydraulic grapple?

As the title says. How effective are grapples with 2 hydraulic tops,---- at back dragging?

I would think too much debris would get by the top teeth, but thought I would ask.

I haven't needed to back drag with the two lids. I pick up the stuff you mentioned going forward with mine.

I have used the front crossbar to back drag dirt into holes left from trees that I pulled.
