I am having trouble finding a significant benefit of that kind of grapple. It seems like more of a gimmick rather than of real benefit. Usually, my grapple on hay, silage ect won't even close enough to activate the "push away" feature. Why would I want my grapple to push my tractor back? Seems like a good way to bend/break my grapple. I could see the push back tines just pushing into the material being moved rather than pushing back the tractor.
