I just bought the GRCS from Shayne and used it on the job today for the first time. All I can say is 'where have you been all my life'. This thing is great. We took down a half dead ash and once I gained a little trust in the unit, I couldn't believe how easy it was to tip tie and winch huge pieces from over the house. Here's a pic of one of the limbs we took when we first started. The brush pieces got bigger as we went and we ended up taking about 20' of the left trunk in one 'pick'. I'm lovin' this thing. Thank you Mr. Good.
