We have a Bobcat root grapple bucket, that has the "open tine" design. It is a fantastic attachment and probably used more than anything else we have for the Bobcat. We use it for stacking brush and limbs, stacking tree trunks and root balls, loading debris, and lately, I have sorted out, stacked, and loaded 20 semi trailer loads of broken concrete from an old dumpsite we are cleaning up. It is built tough and can take a beating.

I own one just like the grapple at the bottom of this page of this link http://www.midsotamfg.com/pages/Grapples/
It works perfect for loading firewood and logging.
