Class 1 - Highly resistant to decay when in ground contact.

Sep 01, Using two wedges, side by side, drive one home so that there is a gap between the stem and the top of the other wedge. Place a shim in the gap above the free wedge until it is snug, and then pound in the shim by driving the wedge.

This should either fell the tree or free up the other wedge. Lean and weight distribution which can be adapted with the use of wedges; Terrain and slope that may add complexity; Advanced level competency standards.

Tree diameter greater than 80cm (but not limited to) Substantial lean; Visible damage or defects that require complex felling techniques; Species prone to splitting and adverse reactions during felling. Limb weight and distribution are critical when choosing tree direction. Be observant of fire damaged limbs or unstable limbs. Your spotter can also observe these limbs for any dangers.

Tree Lean: (Fire-weakened trees) Determine how badly the tree has been compromised by fire and how much of the tree still exists. Examine the topography that the tree is growing on; look at the tree trunk lean.

Intermediate tree felling covers trees with single or multiple stems, limited defects, and lean and weight distribution that can be adapted to felling direction. Advanced tree felling applies to larger and more complex trees and includes trees deemed to be more hazardous/5(51). Nov 10, The tree won't hit where the corners of the notch point unless you compensate with a tapered hinge to offset the weight.

If the tree is balanced then the notch will suffice but not where the tree is unbalanced. Chris, you aren't making the hinge weaker but rather making it stronger by leaving more wood on the tension side. the feller, and felling partner. This is for weight distribution, hiking, or helicopter flight time. Not having the proper equipment can create unsafe conditions. Power Head: The power head that a feller should use is determined by the size of tree that the felling team will be working with.

Have a larger power head available for large tree.
