yea i dont understand this original post either, i am no expert, but have found my gas and hand polesaws handy to trim stuff that would take longer to set up to climb out to than it would to pull the pole saw up the line, but its realy just like an extended arm than a substitute for climbing the tree! i cant imagine taking down a 50 ft tree from the ground, the longerst hand polesaws i have seen are about 25ft, and the longest power ones are usualy about 15 so seems a bit limited, and i sure wouldnt use one of them standing on a ladder, altho maybe if tied in also. but my fear would be a branch landing on the ladder and down it goes!
