How to Cut High Tree Branches: 5 Pro Climbing & Cutting Tips

Cutting high tree branches isn’t just about wielding a chainsaw; it’s about understanding the tree, respecting gravity, and mitigating risk. I’ve seen firsthand what happens when shortcuts are taken or safety is ignored – the results can be devastating. So, let’s dive into the five pro tips that will help you tackle this challenging task with confidence and competence.

1. Mastering the Art of Tree Climbing: Safety First

Tree climbing isn’t just scrambling up a trunk. It’s a controlled ascent using specialized equipment and techniques. I remember one of my first climbs; I thought my youthful agility would be enough. I quickly learned that proper gear and training are non-negotiable.

• Essential Climbing Gear:

  • Climbing Harness: A comfortable, adjustable harness is your lifeline. Look for one specifically designed for tree climbing with multiple attachment points. Brands like Petzl and Buckingham are reputable.
  • Climbing Rope: A low-stretch rope (typically 11-13mm diameter) is crucial. Ensure it’s rated for the dynamic loads of climbing and has a high tensile strength (at least 5,000 lbs). Yale Cordage and Samson Rope are trusted brands.
  • Flipline/Lanyard: A short, adjustable rope used for positioning and securing yourself while working. Wire-core fliplines offer added protection against accidental chainsaw contact.
  • Ascenders/Descenders: Mechanical devices that allow you to efficiently ascend and descend the rope. Options include rope grabs, mechanical prusiks, and controlled descent devices.
  • Helmet: A climbing-specific helmet that meets ANSI Z89.1 standards. Look for features like adjustable vents and a comfortable suspension system.
  • Eye Protection: Safety glasses or goggles are essential to protect your eyes from sawdust and debris.
  • Gloves: Durable work gloves that provide a good grip and protect your hands.

  • Climbing Techniques:

  • Double Rope Technique (DRT): The most common technique, where the climbing rope is anchored above you, creating a loop that you ascend and descend.
  • Single Rope Technique (SRT): Used for accessing very tall trees, involving a single rope anchored at the top. Requires specialized equipment and training.
  • Prusik Hitch: A friction hitch used for ascending and descending ropes. Requires learning how to tie and use the hitch correctly.
  • Pre-Climb Inspection: Before every climb, meticulously inspect your gear for wear and tear. Check ropes for cuts, abrasions, or UV damage. Ensure carabiners lock properly and harnesses are in good condition.
  • Professional Training: I cannot stress this enough: get professional training. Reputable organizations like the International Society of Arboriculture (ISA) offer climbing courses. A certified arborist certification is a great option.

Takeaway: Tree climbing is a skill that demands respect and thorough preparation. Invest in quality gear, learn proper techniques, and prioritize safety above all else.

2. Chainsaw Selection and Maintenance: Your Cutting Companion

The chainsaw is more than just a tool; it’s an extension of your arm when you’re up in a tree. Using the right chainsaw and keeping it in peak condition is paramount for safety and efficiency. I’ve learned the hard way that a dull chain or a poorly maintained saw can quickly turn a manageable task into a dangerous situation.

• Choosing the Right Chainsaw:

  • Top-Handle Chainsaw: These are specifically designed for tree work. They are lightweight, compact, and offer excellent maneuverability. However, they require specialized training and should only be used by experienced climbers.
  • Rear-Handle Chainsaw: Can be used for some aerial work, but generally better suited for ground-based tasks. If using a rear-handle saw aloft, ensure it’s lightweight and you have a secure lanyard to prevent drops.
  • Electric Chainsaws: Battery-powered chainsaws are becoming increasingly popular due to their reduced noise and emissions. They can be a good option for smaller branches, but ensure sufficient battery life for the task.
  • Chainsaw Size: Match the saw size to the branch diameter. Overpowering the cut can lead to loss of control, while an undersized saw will struggle and potentially bind.

  • Chainsaw Maintenance:

  • Chain Sharpening: A sharp chain is crucial for efficient cutting and safety. Learn to sharpen your chain with a file or use a chain grinder. Dull chains increase the risk of kickback. I personally sharpen my chains after every single job.

  • Chain Tension: Regularly check and adjust chain tension. A loose chain can derail, while an overtight chain can overheat and damage the saw.
  • Bar Maintenance: Clean the bar groove regularly to remove sawdust and debris. Check the bar for wear and burrs, and dress it with a file as needed.
  • Air Filter: Keep the air filter clean to ensure proper engine performance. A clogged air filter can cause the engine to run poorly and overheat.
  • Fuel Mixture: Use the correct fuel mixture as specified by the manufacturer. Old or improperly mixed fuel can damage the engine.
  • Safety Features: Ensure all safety features, such as the chain brake and throttle lock, are functioning correctly. Test them before each use.

  • Chainsaw Safety Gear:

  • Chainsaw Chaps: Essential leg protection. Look for chaps that meet OSHA standards.

  • Hearing Protection: Chainsaws are loud. Use earplugs or earmuffs to protect your hearing.
  • Face Shield: Provides added protection against flying debris.

Takeaway: A well-maintained chainsaw is a safe and efficient tool. Invest time in learning proper maintenance procedures and always wear appropriate safety gear.

3. Branch Assessment and Cutting Strategy: Plan Your Attack

Before you even start the engine, take the time to assess the branch you’re about to cut. Understanding the branch’s weight, angle, and potential fall path is crucial for a safe and controlled cut. I’ve seen too many near misses caused by impulsive cutting without a clear plan.

• Branch Assessment:

  • Size and Weight: Estimate the branch’s weight to determine the appropriate cutting technique and rigging requirements. Large, heavy branches require careful planning and potentially the use of ropes and pulleys.
  • Angle and Lean: Observe the branch’s angle and lean. This will influence its natural fall path.
  • Structural Integrity: Check for signs of decay, cracks, or weak points. These can affect the branch’s behavior during cutting.
  • Obstacles: Identify any obstacles in the branch’s potential fall path, such as power lines, buildings, or other trees.

  • Cutting Techniques:

  • Undercut and Overcut: This is the most common technique for felling trees and cutting branches. Make an undercut about one-third of the way through the branch, followed by an overcut a few inches above the undercut. This prevents the branch from splitting and tearing the bark.
  • Notching: For larger branches, create a notch on the underside of the branch to control the direction of the fall.
  • Bore Cutting: A technique used to remove a section of the branch’s core, reducing its weight and making it easier to control. Requires advanced chainsaw skills.
  • Step Cutting: For very large branches, cut the branch in sections, working your way from the tip towards the trunk.

  • Rigging and Lowering:

  • Ropes and Pulleys: Use ropes and pulleys to lower large branches in a controlled manner. This prevents damage to property and reduces the risk of injury.

  • Friction Devices: Use friction devices, such as a Port-a-Wrap or bollard, to control the speed of the rope as the branch is lowered.
  • Rigging Points: Select strong and secure rigging points on the tree to support the weight of the branch.
  • Communication: If you’re working with a ground crew, establish clear communication signals before starting the cut. Use hand signals or radios to coordinate your actions.

Takeaway: A well-thought-out cutting strategy is essential for safety and efficiency. Take the time to assess the branch, choose the appropriate cutting technique, and use rigging equipment when necessary.

4. Safe Climbing and Cutting Practices: Minimize the Risks

Even with the best equipment and training, tree work is inherently dangerous. Adhering to safe climbing and cutting practices is crucial to minimize the risks. I’ve developed a set of personal rules over the years, based on both formal training and hard-earned experience.

• Three Points of Contact: Always maintain three points of contact with the tree – two hands and one foot, or two feet and one hand. This ensures stability and prevents falls.
• Secure Positioning: Before making a cut, ensure you are securely positioned and anchored to the tree. Use your flipline or lanyard to create a stable work platform.
• Clear Work Zone: Establish a clear work zone on the ground below. Keep bystanders away and ensure there are no obstacles in the potential fall path of the branch.
• Situational Awareness: Be aware of your surroundings at all times. Watch out for overhead hazards, such as power lines or falling debris.
• Fatigue Management: Tree work is physically demanding. Take frequent breaks to avoid fatigue. Fatigue can impair judgment and increase the risk of accidents.
• Weather Conditions: Avoid climbing in adverse weather conditions, such as high winds, rain, or lightning. These conditions can make the work significantly more dangerous.
• Emergency Plan: Have an emergency plan in place in case of an accident. Know how to contact emergency services and have a first-aid kit readily available.
• No Shortcuts: Never take shortcuts or compromise on safety. It’s better to take extra time to do the job right than to risk injury or damage. I always say, “There’s no such thing as a small mistake up in a tree.”

Takeaway: Safe climbing and cutting practices are non-negotiable. Always prioritize safety, maintain situational awareness, and avoid taking shortcuts.

5. Post-Cut Cleanup and Inspection: Leaving No Trace

The job isn’t done when the branch hits the ground. Proper cleanup and inspection are essential for leaving the site safe and aesthetically pleasing. I’ve always believed that a professional arborist leaves a property better than they found it.

• Branch Removal: Remove all cut branches and debris from the work zone. Use a chipper to reduce the volume of branches and make them easier to dispose of.
• Stump Treatment: Treat the cut end of the branch with a pruning sealer to prevent disease and insect infestation.
• Wound Inspection: Inspect the remaining tree for any damage caused during the cutting process. Repair any damaged bark or branches.
• Ground Cleanup: Rake up any sawdust or debris from the ground. Repair any damage to lawns or landscaping.
• Tool Maintenance: Clean and inspect your tools after each use. Sharpen the chainsaw chain, clean the bar, and lubricate moving parts.
• Customer Satisfaction: Walk the property with the customer to ensure they are satisfied with the work. Address any concerns they may have.
• Documentation: Keep a record of the work performed, including the date, location, and type of work. This can be helpful for future reference and insurance purposes.

Takeaway: Post-cut cleanup and inspection are essential for leaving the site safe and aesthetically pleasing. Take pride in your work and ensure the customer is satisfied with the results.

Additional Considerations for Different Tree Species

The specific approach to cutting high tree branches can vary depending on the species of tree you’re working with. Different species have different growth habits, wood densities, and susceptibility to disease.

• Oak Trees: Oak trees are prone to oak wilt, a fungal disease that can be spread by pruning during certain times of the year. Avoid pruning oak trees during the spring and early summer months. If pruning is necessary during this time, use a pruning sealer on the cut ends.
• Pine Trees: Pine trees are susceptible to pine bark beetles, which can infest trees that are stressed or damaged. Avoid pruning pine trees during periods of drought or insect infestation.
• Fruit Trees: Fruit trees require regular pruning to promote fruit production. Prune fruit trees during the dormant season to encourage new growth in the spring.
• Maple Trees: Maple trees are known for their sap flow, which can be messy and attract insects. Avoid pruning maple trees during the late winter and early spring when sap flow is at its peak.
• Palm Trees: Palm trees require specialized pruning techniques. Avoid over-pruning palm trees, as this can weaken the tree and make it more susceptible to disease.

Dealing with Hazardous Trees

Sometimes, cutting high tree branches is necessary to address hazardous trees that pose a risk to people or property. A hazardous tree is one that has structural defects, disease, or other conditions that make it likely to fail.

• Hazard Assessment: Before cutting any branches, conduct a thorough hazard assessment of the tree. Look for signs of decay, cracks, or other structural defects.
• Professional Consultation: If you suspect that a tree is hazardous, consult with a certified arborist. An arborist can assess the tree and recommend the appropriate course of action.
• Removal vs. Pruning: In some cases, pruning may be sufficient to address the hazard. However, in other cases, the tree may need to be removed entirely.
• Specialized Equipment: Removing hazardous trees often requires specialized equipment, such as cranes or aerial lifts.
• Safety Precautions: Take extra safety precautions when working with hazardous trees. These trees are more likely to fail unexpectedly, so it’s important to be vigilant and prepared.

The Importance of Ongoing Education

The field of arboriculture is constantly evolving, with new techniques, technologies, and best practices emerging all the time. It’s important to stay up-to-date on the latest developments by attending workshops, reading industry publications, and participating in professional organizations.
