Simply so, what are felling wedges used for?Wedges can be used in many felling plans to replace the rope and can be used in conjunction with rope to increase results and to support safety. Some wedge thoughts… A wedge can be used to lift a tree’s back lean into the desired position/direction. A wedge can support and stabilize a tree’s weight during a back cut.Similarly, how do you cut a tree with a wedge? First, I cut the notch as normal, with the notch face pointing in the desired direction of tree fall. Then I start the felling cut and stop when there is just enough room in the back cut to insert a wedge without it touching my chain. I position the wedge so that it points in the direction I want the tree to fall. Simply so, what size felling wedge do I need? The larger wedge you use for falling trees the better the lift it has. If your trees are in the 18″ range, a 7 1/2″ wedge should be sufficient, provided you don’t use a tack hammer to drive them, but I’d carry at least 4. It’s better to have them and not need them, than to need them and not have them.How do I make felling wedges?Position the wedge so that it goes in the direction you want the tree to fall. Slice a little more into the tree (without finishing the felling cut) and then halt to drive a second wedge two to six inches away from the first. Hit the second wedge in with your ax until it is taut.
