1. Mastering the Felling Cut (Especially with Large Diameter Wood)

Felling trees, especially with a large saw like the MS 881, is not something to take lightly. I’ve personally witnessed the consequences of improper felling techniques – from near misses to actual injuries and damage to equipment. The MS 881, with its 60-inch bar, is designed for tackling truly massive trees, but that immense power demands respect and precision.

Understanding the Importance of Proper Felling

Proper felling is crucial for several reasons:

• Safety: The most important aspect. A miscalculated fall can injure yourself or others.
• Efficiency: Felling the tree where you want it saves time and effort in moving the log later.
• Wood Utilization: Minimizing damage to the tree during the fall reduces waste.
• Environmental Impact: Controlled felling minimizes damage to surrounding vegetation.

Key Concepts:

• Lean: The natural angle at which the tree is inclined.
• Weight Distribution: Where the majority of the tree’s mass is concentrated.
• Hinge: A strip of wood left uncut that controls the direction of the fall.
• Holding Wood: The wood directly behind the hinge that helps prevent premature falling.
• Back Cut: The final cut made to fell the tree.

Step-by-Step Felling Guide for Large Trees (MS 881 with 60-inch Bar):

Step 1: Assessment and Planning

• Inspect the Tree: Look for lean, weight distribution, dead limbs, and any signs of rot or disease. Also, note the wind direction.
• Plan the Escape Route: Identify two escape routes at a 45-degree angle away from the intended fall direction. Clear any obstacles in these routes.
• Assess the Surroundings: Check for power lines, roads, buildings, or other hazards.
• Determine the Felling Direction: Choose a direction that aligns with the lean and weight distribution, and avoids hazards. Use wedges if necessary to influence the fall.

Step 2: Personal Protective Equipment (PPE)

• Helmet: ANSI-approved with a face shield.
• Eye Protection: Safety glasses or goggles.
• Hearing Protection: Earplugs or earmuffs.
• Gloves: Heavy-duty work gloves.
• Chainsaw Chaps: Essential for leg protection.
• Steel-Toed Boots: Provide foot protection.

Step 3: The Notch Cut (or Face Cut)

• Purpose: To guide the tree’s fall.
• Type: Open-face notch is generally recommended for larger trees.
• Angle: Aim for a 70-90 degree notch angle. This allows for a wider range of fall directions and helps prevent the tree from kicking back.
• Depth: The notch should be approximately 1/5 to 1/3 of the tree’s diameter.
• Execution:
  • Top Cut: Start with a downward angled cut, aiming towards the center of the tree.
  • Bottom Cut: Make an upward angled cut to meet the top cut, creating the notch. Remove the wedge of wood.

Step 4: The Back Cut

• Purpose: To sever the remaining wood and allow the tree to fall.
• Height: Make the back cut slightly above the apex of the notch cut (usually 1-2 inches).
• Holding Wood: Leave a strip of holding wood (the hinge) to control the fall. The width of the hinge depends on the tree’s diameter but is generally 1-2 inches. This is crucial. Too little hinge, and the tree can fall unpredictably. Too much, and it might not fall at all.
• Execution:
  • Carefully insert the saw: Ensure you have a firm grip and stable footing.
  • Maintain a consistent cutting speed: Avoid forcing the saw. Let the chain do the work.
  • Watch for signs of movement: Be prepared to react quickly if the tree starts to fall unexpectedly.
• Wedges (Essential for Large Trees):
  • Purpose: To prevent the tree from pinching the saw bar and to help direct the fall.
  • Material: Use plastic or aluminum wedges. Avoid steel wedges, as they can damage the chain if accidentally contacted.
  • Placement: Insert wedges into the back cut as you proceed. Drive them in with a sledgehammer to gradually push the tree in the desired direction.

Step 5: The Final Cut and Escape

• Final Cut: Once the wedges are firmly in place, make the final cut through the holding wood.
• Escape: As the tree begins to fall, immediately move away using your pre-planned escape route. Keep your eye on the falling tree.
• Caution: Be aware of “widow makers” – loose branches that can fall after the tree is down.

Case Study: Felling a Large Oak (My Experience)

I once had to fell a massive oak tree that was leaning precariously close to a neighbor’s house. The diameter at chest height was over 5 feet. The stakes were high – a miscalculation could have resulted in significant property damage.

I meticulously planned the felling direction, opting for a slight angle away from the house. Because of the tree’s size and lean, I used two large felling wedges. I constantly monitored the tree’s movement as I drove the wedges, making small adjustments as needed. The MS 881, with its power and long bar, handled the cut with ease. The tree fell precisely as planned, avoiding any damage. The key was patience, careful observation, and the use of appropriate tools and techniques.
