They don't use pole pruners that often.
What they usually do is use a 28' extension ladder to access the canopy, use their pole saw to advance their climbing line into the tree (as often as needed to reach the desired tie in point) then hang in the center of the area they are pruning, and proceed to use their pole saw to make all of their cuts outside of an arms reach away, then move on to the next area. In the case of multiple climbers in a tree, if I am climbing with one of then I can cover the same amount of ground in the same time, as it takes them to use a pole saw. One half of the tree has nice professional cuts, and the other looks like the homeowner was up their on a ladder hacking away. Some of then might as well not even take a hand saw with them, that’s how much they rely on a pole saw.
Im sorry but we are climber and i do not see the point of a ladder. Can some one please explain why some one would use a ladder if you can climb?
