See this is exactly why I don't let my husband do any tree maintenance on our property! It's not worth the risk! Our tree service in Salem, Oregon (Oregon Woodsmen - http://oregonwoodsmen.com/) always utilizes solid and upgraded equipment so they get the job (trimming, pruning, removing, etc) done efficiently. I'd question whether this arborist was using out of date equipment like some contractors/DIY'ers tend to do..?
