Planning and Preparation: The Foundation of Safe Felling

Before even thinking about firing up a chainsaw or climbing into a bucket lift, meticulous planning is crucial. This stage is where you significantly reduce the risk of accidents and ensure a controlled felling operation.

1. Site Assessment: Knowing Your Battlefield

• Tree Inspection: The first step is to thoroughly inspect the tree. Look for signs of decay, disease, or damage. Are there any large dead limbs (widow makers) that could pose a hazard? What is the tree’s natural lean?
  • Technical Detail: I use a tree caliper to measure the diameter at breast height (DBH), typically 4.5 feet from the ground. This measurement helps estimate the tree’s weight and determine the appropriate chainsaw size and felling techniques. A DBH of over 30 inches requires careful consideration and potentially specialized equipment.
• Surrounding Environment: Identify potential hazards like power lines, buildings, roads, or other trees. Determine the “drop zone” – the area where the tree is expected to fall. Clear this area of any obstacles and personnel.
  • Personal Experience: I once worked on a project near a residential area where a seemingly straightforward felling became incredibly complex due to the proximity of power lines. We had to consult with the utility company and employ specialized rigging techniques to ensure the tree fell safely away from the lines.
• Weather Conditions: Wind speed and direction are critical factors. High winds can make felling unpredictable and dangerous. Avoid felling in gusty conditions or when wind speeds exceed 20 mph.
  • Data Point: Studies have shown that tree felling accidents increase by as much as 30% during periods of high winds. Always prioritize safety over speed.

2. Equipment Selection and Inspection: Arming Yourself for Success

• Bucket Lift Inspection: Before each use, meticulously inspect the bucket lift. Check the hydraulic hoses for leaks or damage, ensure the controls are functioning properly, and verify that the safety harness and fall arrest system are in good condition.
  • Technical Detail: Refer to the manufacturer’s specifications for the bucket lift’s maximum load capacity. Never exceed this limit, considering the weight of the operator, tools, and any cut sections of the tree.
• Chainsaw Selection and Maintenance: Choose a chainsaw appropriate for the size of the tree. Ensure the chain is sharp and properly tensioned, and that the saw is well-lubricated.
  • Technical Detail: I prefer using a chainsaw with a bar length that is at least two inches longer than the diameter of the tree I’m cutting. This allows for efficient cutting without overextending the saw.
  • Personal Experience: I once tried to fell a large oak with a chainsaw that was too small for the job. The saw got pinched in the cut, and it took me considerable effort to free it. I learned a valuable lesson that day about using the right tool for the job.
• Personal Protective Equipment (PPE): Never compromise on PPE. This includes a hard hat, safety glasses, hearing protection, chainsaw chaps, gloves, and steel-toed boots.
  • Industry Standard: OSHA regulations mandate the use of appropriate PPE for all tree felling operations. Failure to comply can result in fines and, more importantly, serious injuries.

3. Developing a Felling Plan: Charting the Course

• Determine the Felling Direction: Based on the tree’s lean, wind direction, and surrounding obstacles, decide which way you want the tree to fall.
• Plan the Escape Route: Before making any cuts, identify a clear escape route that is at a 45-degree angle away from the anticipated direction of fall.
• Communicate with Your Team: If working with a team, ensure everyone understands the felling plan and their roles. Establish clear communication signals.

Safe Bucket Lift Operation: Reaching New Heights Responsibly

Operating a bucket lift safely requires specialized knowledge and adherence to strict procedures. Never operate a bucket lift without proper training and certification.

1. Pre-Operation Checks: Ensuring Stability and Functionality

• Ground Conditions: Before positioning the bucket lift, ensure the ground is firm and level. Avoid operating on slopes or soft soil.
  • Technical Detail: Use outriggers or stabilizers to provide additional support and prevent tipping. Consult the manufacturer’s specifications for the maximum allowable slope for operation.
• Overhead Obstructions: Be aware of overhead power lines, branches, or other obstructions that could interfere with the bucket lift’s operation. Maintain a safe distance from power lines – typically at least 10 feet.
• Functionality Tests: Before raising the bucket, test all controls to ensure they are functioning smoothly. Check the emergency stop button to verify it is working correctly.

2. During Operation: Maintaining Awareness and Control

• Harness and Fall Arrest System: Always wear a safety harness and lanyard that is properly attached to the bucket. This will prevent you from falling out of the bucket in the event of a sudden movement.
• Smooth Movements: Operate the bucket lift smoothly and avoid sudden jerks or movements that could destabilize the machine.
• Communication: Maintain constant communication with the ground crew. Use hand signals or a two-way radio to coordinate movements.
• Awareness: Be constantly aware of your surroundings and potential hazards. Watch out for falling branches or other debris.

3. Emergency Procedures: Preparing for the Unexpected

• Emergency Stop: Know the location and operation of the emergency stop button.
• Lowering the Bucket: In the event of an emergency, such as a mechanical failure or sudden change in weather, immediately lower the bucket to the ground.
• Evacuation Plan: Have a pre-determined evacuation plan in case the bucket lift becomes disabled.

Felling Techniques from a Bucket Lift: Precision and Control

Felling trees from a bucket lift requires a different approach than felling from the ground. You have greater control over the cutting process, but you also need to be aware of the unique hazards associated with working at height.

1. Making the Cuts: Strategic Precision

• Notch Cut: The notch cut determines the direction of fall. From the bucket, I carefully make a notch cut on the side of the tree facing the desired direction of fall. The notch should be at least one-third of the tree’s diameter.
  • Technical Detail: The angle of the notch cut is crucial. A 45-degree angle is generally recommended, but the exact angle may vary depending on the tree’s lean and other factors.
• Back Cut: The back cut is made on the opposite side of the tree from the notch cut. Leave a hinge of uncut wood between the back cut and the notch cut. This hinge will help control the tree’s fall.
  • Technical Detail: The thickness of the hinge is critical. A hinge that is too thin will break prematurely, causing the tree to fall unpredictably. A hinge that is too thick will prevent the tree from falling at all. I usually aim for a hinge that is about 10% of the tree’s diameter.
  • Personal Experience: I once made a back cut that was too deep, leaving a very thin hinge. As I was making the final cut, the tree suddenly snapped and fell in an unexpected direction. Fortunately, no one was injured, but it was a close call.
• Holding Wood: When working with particularly large or heavy trees, I often leave “holding wood” on either side of the back cut. This helps prevent the tree from splitting or barber chairing as it falls. Barber chairing happens when the tree splits vertically up the trunk during felling, creating a dangerous situation.
• Top-Down Cutting: In some cases, especially with trees that have a significant lean, it may be safer to make cuts from the top down. This involves removing smaller sections of the tree gradually, reducing the overall weight and strain on the trunk.

2. Managing the Fall: Controlled Descent

• Wedges: Use wedges to help direct the fall of the tree. Insert wedges into the back cut to prevent the tree from leaning back against the saw.
• Pulling Ropes: Attach pulling ropes to the tree to help guide its fall. Have a ground crew pull on the ropes to encourage the tree to fall in the desired direction.
• Communication: Maintain constant communication with the ground crew to ensure everyone is aware of the tree’s movement.

3. Addressing Hangups: Staying Safe and Smart

• Avoid Cutting the Hinge: Never cut the hinge of a hung-up tree from the bucket lift. This is extremely dangerous and could cause the tree to fall in an unpredictable direction.
• Use Mechanical Advantage: Use a winch or come-along to pull the tree down. Attach the winch or come-along to a sturdy anchor point and gradually apply tension until the tree falls.
• Call for Help: If you are unable to safely dislodge the hung-up tree, call for professional assistance.

Wood Processing and Firewood Preparation: From Forest to Flame

Once the tree is safely on the ground, the work is far from over. Processing the wood into usable lumber or firewood requires additional steps and considerations.

1. Log Dimensions and Cutting Patterns: Maximizing Yield

• Log Lengths: Cut the tree into logs of appropriate lengths for your intended use. For lumber, standard lengths are typically 8, 10, 12, 14, or 16 feet. For firewood, lengths are typically 16 inches, but may vary depending on the size of your wood stove or fireplace.
  • Technical Detail: When cutting logs for lumber, consider the taper of the tree. Cut shorter logs from the top of the tree to minimize waste.
• Cutting Patterns: Plan your cuts carefully to maximize the yield of usable wood. Avoid cutting through knots or other defects.
  • Visual Example: I like to use a diagram to plan my cuts before I start sawing. This helps me visualize the best way to maximize the yield and minimize waste.

2. Wood Selection Criteria: Knowing Your Wood

• Hardwoods vs. Softwoods: Understand the differences between hardwoods and softwoods. Hardwoods are generally denser and burn longer, making them ideal for firewood. Softwoods are easier to work with and are often used for construction.
  • Data Point: Hardwoods typically have a density of 40 lbs per cubic foot or higher, while softwoods have a density of 30 lbs per cubic foot or lower.
• Species Selection: Different species of wood have different properties. Oak is a popular choice for firewood due to its high density and long burning time. Pine is a softwood that is easy to ignite but burns quickly.
• Decay and Disease: Avoid using wood that is decayed or diseased. This wood will be weak and may not burn well.

3. Firewood Preparation: Seasoning and Storage

• Splitting: Split the logs into smaller pieces to facilitate drying. Use a hydraulic log splitter for efficiency and safety.
  • Technical Detail: Split logs along the grain to make the process easier.
• Seasoning: Allow the firewood to season (dry) for at least six months before burning. This will reduce the moisture content and improve its burning efficiency.
  • Technical Detail: The ideal moisture content for firewood is below 20%. Use a moisture meter to check the moisture content before burning.
  • Data Point: Burning unseasoned firewood can reduce the efficiency of your wood stove or fireplace by as much as 50%.
• Storage: Store the firewood in a well-ventilated area, away from moisture and pests. Cover the top of the stack to protect it from rain and snow.

4. Technical Specifications for Firewood

• Moisture Content: The key to efficient and clean burning firewood is its moisture content.
  • Acceptable Range: Firewood should have a moisture content of 15-20% for optimal burning.
  • Measurement: Use a reliable wood moisture meter to accurately measure the moisture content. Insert the meter probes into freshly split faces of several pieces of wood from different parts of the stack.
  • Drying Times: Drying times vary based on wood species, climate, and stacking methods. Generally, hardwoods require 6-12 months of seasoning, while softwoods may dry in 3-6 months.
• Log Dimensions: Consistent log dimensions ensure efficient stacking and burning.
  • Standard Length: The most common firewood length is 16 inches, but this can vary based on the size of your stove or fireplace. Measure accurately and cut consistently.
  • Diameter: The ideal diameter for firewood pieces is 4-6 inches. Larger pieces may be difficult to ignite and burn unevenly.
• Wood Density and BTU Value: Different wood species have varying densities and heat outputs.
  • High BTU Woods: Oak, maple, and beech are high-density hardwoods with high BTU (British Thermal Unit) values, meaning they produce more heat per unit volume.
  • Low BTU Woods: Pine, fir, and poplar are low-density softwoods with lower BTU values. They burn faster and are better suited for kindling.
• Stacking Methods: Proper stacking promotes air circulation and efficient drying.
  • Loose Stacking: Leave gaps between logs when stacking to allow for airflow.
  • Elevated Stacking: Stack firewood on pallets or racks to keep it off the ground and prevent moisture absorption.
• Storage Location: Choose a storage location that is sheltered from rain and snow but still allows for adequate ventilation.
  • Covering: Cover the top of the woodpile with a tarp or roof to protect it from precipitation.
  • Sun Exposure: Maximize sun exposure to promote drying, but avoid direct sunlight on the entire pile, as it can cause surface checking (cracking).

Safety Codes and Regulations: Adhering to the Law

Tree felling and wood processing are regulated activities. It is essential to be aware of and comply with all applicable safety codes and regulations.

1. OSHA Standards: Protecting Workers

• Personal Protective Equipment (PPE): OSHA regulations mandate the use of appropriate PPE for all tree felling operations.
• Training and Certification: OSHA requires that all tree fellers be properly trained and certified in safe felling techniques.
• Equipment Inspection: OSHA requires that all equipment be inspected regularly to ensure it is in good working order.

2. Environmental Regulations: Protecting the Environment

• Permits: Obtain the necessary permits before felling trees.
• Erosion Control: Implement erosion control measures to prevent soil erosion and water pollution.
• Replanting: Replant trees to replace those that have been felled.

3. Local Ordinances: Respecting the Community

• Noise Restrictions: Be aware of local noise restrictions and avoid operating equipment during restricted hours.
• Burning Regulations: Follow local burning regulations when disposing of slash and debris.
• Property Lines: Respect property lines and avoid felling trees that are on neighboring properties.
