Then I had enough, reminded me of my great Fiskars ax and the mighty lopper, which we have already ordered and finally the Fiskars Ergonomic. Fifteen minutes later roots were undermined, I was able to use my whole body weight.
In addition, you shoveled by the angled handle also playing a wheelbarrow full. Never again another spade !!!
Addendum about a year later:
After-completed construction and tons of mud, many stones, trenches, roots, antifreeze, gravel etc. the spade is still waiting serious opponents. Only the plastic coating on the shaft has a little relieved. As before, my purpose weapon (currently invest in lawn / excavation to shovel).
