a three-stage technical illustration of a controlled tree-felling process, likely designed for educational or instructional purposes. It uses a composite layout to show the progression from the initial cut to the final fall.
VISUAL BREAKDOWN OF THE STAGES
The image is divided into three numbered sections, each representing a critical step in directional felling:
1. THE FACE CUT (NOTCH)
On the left, the tree is shown with a "V" shaped notch (also known as a face cut) removed from the trunk.
• Purpose: This cut determines the direction in which the tree will fall.
• Detail: An arrow points into the notch, highlighting where the wood has been removed to create a "hinge" point.
2. THE BACK CUT AND WEDGING
On the right, the illustration adds safety and control measures.
• The Back Cut: A horizontal cut is made on the opposite side of the notch.
• Felling Wedge: A wooden or plastic wedge is inserted into the back cut (indicated by an arrow). This prevents the tree from leaning backward and pinching the saw, while also helping to "push" the tree toward the notch.
• Safety Chains: Chains are wrapped around the trunk above and below the cuts, connected by a vertical tensioner. This is a safety technique used to prevent "barber chairing"—a dangerous situation where the tree splits vertically and kicks back toward the operator.
3. THE FINAL FALL
At the bottom, the sequence concludes with the tree successfully felled.
• The Result: The main trunk has separated from the stump and is resting on the ground.
• Hinge Visibility: You can see the clean break at the stump where the notch and back cut met, leaving the "hinge" of wood that guided the fall.
• Chain Position: The safety chains remain attached to the base, illustrating that they stayed in place throughout the tension of the fall.
TECHNICAL OBSERVATIONS
• Environment: The setting is a dense, sun-dappled forest with soft-focus background trees, emphasizing the specific subject in the foreground.
• Clarity: The use of numbered stages and directional arrows makes this a "how-to" style graphic, focusing on the physics and safety of logging.
• Safety Note: Tree felling is extremely hazardous and should only be performed by trained professionals using appropriate personal protective equipment (PPE).
