I have one of those brush grubbers and overall it works pretty well -- I just wish they showed a better size perspective on some of the websites or listed the weight. The one I ordered is crazy-heavy and the spring is tough to open and it's physical size is bigger than what I would have expected relative to the jaw width. Its definitely a high-quality heavy duty tool, but it wears your arms out after a day of using it to pull stumps. Originally, the plan was for my 12 year old to hook it to the stumps/roots and I'd pull them out without leaving the seat, but it was too stiff for him to open after the first few saplings... and he plays defensive end on his football team.
