Bush Chainsaw Tips for Pruning: 5 Pro Woodcutting Hacks
1. The Right Saw for the Right Job: Chainsaw Selection and Preparation
Before you even think about firing up your chainsaw, you need to ensure you have the right tool for the job. Using a massive logging saw to prune delicate branches is like using a sledgehammer to crack a nut – overkill and likely to cause more damage than good.
Chainsaw Selection:
- For Smaller Branches (up to 4 inches): I recommend a lightweight, top-handled chainsaw with a 10-12 inch bar. These saws are designed for maneuverability and precision, making them ideal for navigating tight spaces within a tree canopy. A good example is the Stihl MS 150 TC-E, which weighs around 6.4 lbs. (without fuel and bar) and offers excellent control.
- For Medium Branches (4-8 inches): A mid-sized chainsaw with a 14-16 inch bar is a good choice. These saws offer a balance of power and control, allowing you to tackle larger branches without sacrificing maneuverability. I’ve had great success with the Husqvarna 455 Rancher, which offers a good power-to-weight ratio and is known for its reliability.
- For Larger Branches (8 inches and up): A larger chainsaw with an 18-20 inch bar might be necessary. However, I generally advise against using a chainsaw of this size for pruning unless you’re dealing with exceptionally large branches on mature trees. The risk of overcutting and damaging the tree is significantly higher. In such cases, consider using a smaller saw for the majority of the pruning and reserving the larger saw for the final cuts.
Chainsaw Preparation:
- Chain Sharpness: This is absolutely crucial. A dull chain not only makes the job harder but also increases the risk of kickback. I sharpen my chains regularly using a chainsaw sharpening kit, aiming for a consistent angle and depth on each tooth. A sharp chain should pull itself into the wood with minimal pressure.
- Chain Tension: Proper chain tension is essential for safe and efficient cutting. The chain should be snug against the bar but still able to be pulled around by hand. Too loose, and the chain can derail; too tight, and it can overheat and wear out prematurely.
- Bar Lubrication: Ensure the bar oil reservoir is full and that the oiler is functioning properly. Insufficient lubrication can lead to excessive wear on the bar and chain. I prefer using a high-quality bar and chain oil specifically designed for chainsaws.
- Safety Features: Familiarize yourself with the safety features of your chainsaw, including the chain brake, throttle lock, and anti-vibration system. Make sure they are all functioning correctly before you start working.
Personal Experience:
I once made the mistake of using an overly powerful chainsaw with a long bar to prune some apple trees in my orchard. The result was disastrous. I ended up removing far too much wood, leaving the trees looking unbalanced and vulnerable to disease. I quickly learned the importance of using the right tool for the job and now always reach for my smaller, top-handled saw for pruning tasks.
Data and Insights:
Studies have shown that using a properly sharpened chainsaw can reduce cutting time by up to 30% and significantly decrease the risk of kickback. Regular maintenance and proper chain tension can also extend the lifespan of your chainsaw by several years.
2. The Art of the Angle: Understanding Branch Collars and Pruning Cuts
Pruning isn’t just about lopping off branches; it’s about making precise cuts that promote healthy growth and minimize the risk of disease. Understanding the anatomy of a branch and the principles of pruning cuts is essential for achieving optimal results.
Branch Collars:
The branch collar is the swollen area at the base of a branch where it joins the trunk. It contains specialized cells that facilitate wound closure and prevent decay from spreading into the main stem. When pruning, it’s crucial to avoid damaging the branch collar.
Pruning Cuts:
- Branch Removal Cut: This is the most common type of pruning cut, used to remove entire branches. The cut should be made just outside the branch collar, at an angle that mirrors the natural angle of the collar. Avoid flush cuts, which remove the branch collar and can hinder wound closure.
- Reduction Cut: This cut is used to shorten a branch or redirect its growth. The cut should be made back to a lateral branch that is at least one-third the diameter of the branch being removed. This helps to maintain the natural form of the tree and promotes healthy growth.
- Thinning Cut: This cut is used to remove branches at their point of origin, either at the trunk or at a larger branch. This helps to improve air circulation and sunlight penetration within the tree canopy.
The 3-Cut Method for Larger Branches:
When removing larger branches, I always use the 3-cut method to prevent the bark from tearing and damaging the trunk:
- Undercut: Make a cut on the underside of the branch, about 12-18 inches from the trunk, cutting about one-third of the way through.
- Top Cut: Make a cut on the top side of the branch, a few inches further out from the undercut. This cut will cause the branch to break away, preventing it from tearing the bark.
- Final Cut: Make the final cut just outside the branch collar, at the correct angle.
Personal Experience:
I remember once watching a neighbor prune a large oak tree using a single, haphazard cut to remove a massive branch. The weight of the branch caused the bark to tear all the way down the trunk, creating a gaping wound that exposed the tree to disease. It was a painful lesson in the importance of proper pruning techniques.
Data and Insights:
Research has shown that proper pruning cuts can significantly reduce the risk of decay and disease in trees. Trees that are pruned correctly are also more likely to produce healthy growth and abundant fruit. Improper pruning, on the other hand, can weaken trees and make them more susceptible to pests and diseases.
3. Mastering the Bore Cut: A Technique for Controlled Felling and Pruning
The bore cut is an advanced chainsaw technique that involves plunging the tip of the chainsaw bar into the wood to create a pocket or notch. It’s a valuable tool for controlled felling and pruning, allowing you to direct the fall of a tree or limb and prevent it from splitting or tearing.
How to Perform a Bore Cut:
- Positioning: Stand in a stable position with a firm grip on the chainsaw. Ensure there are no obstructions in the path of the bar.
- Starting the Cut: With the chainsaw running at full throttle, carefully plunge the tip of the bar into the wood at a slight angle. Use the bottom of the bar to guide the saw and prevent kickback.
- Creating the Pocket: Once the tip of the bar is fully embedded in the wood, slowly pivot the saw to create a pocket or notch.
- Completing the Cut: Continue pivoting the saw until you have created the desired cut. Be careful not to pinch the bar, which can cause the saw to stall.
Applications of the Bore Cut in Pruning:
- Removing Large Limbs: When removing large limbs, a bore cut can be used to create a hinge that controls the direction of the fall. This is particularly useful when working in confined spaces or near structures.
- Preventing Splitting: By making a bore cut on the underside of a branch before making the final cut, you can prevent the branch from splitting or tearing as it falls.
- Creating Notches: Bore cuts can be used to create precise notches in branches, which can be useful for attaching ropes or rigging equipment.
Safety Precautions:
- Kickback: The bore cut is a high-risk technique that can result in kickback if not performed correctly. Always be aware of the position of the tip of the bar and avoid pinching it.
- Experience: The bore cut should only be attempted by experienced chainsaw users who are familiar with the risks involved.
- Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
Personal Experience:
I once used a bore cut to safely remove a large limb from a tree that was growing dangerously close to a power line. By carefully controlling the direction of the fall, I was able to avoid any contact with the power line and prevent a potentially dangerous situation.
Data and Insights:
The bore cut is a technique that requires practice and precision. However, when performed correctly, it can significantly improve the safety and efficiency of chainsaw work. Studies have shown that experienced chainsaw users who are proficient in the bore cut are less likely to experience accidents or injuries.
4. Limb Walking: Safe and Efficient Movement in the Tree Canopy
“Limb walking” refers to the technique of moving around within the tree canopy to reach and prune branches. While it might seem intuitive, there’s a right way and a very wrong way to do it, and the wrong way can lead to serious injury.
Essential Safety Gear:
- Climbing Harness: A properly fitted climbing harness is the foundation of safe limb walking. Look for one that meets ANSI standards and is designed for tree work.
- Climbing Rope (Lanyard): A strong, dynamic climbing rope (lanyard) is used to secure yourself to the tree. Choose a rope that is specifically designed for climbing and has a high breaking strength.
- Carabiners: Use locking carabiners to connect your harness to the climbing rope. Ensure the carabiners are rated for climbing and are in good condition.
- Helmet: A climbing helmet is essential for protecting your head from falling debris.
- Eye Protection: Safety glasses or a face shield will protect your eyes from sawdust and other debris.
- Gloves: Gloves will provide a better grip and protect your hands from cuts and abrasions.
Technique and Considerations:
- Assess the Tree: Before climbing, carefully assess the tree for any signs of weakness, such as dead branches, cracks, or decay.
- Establish a Secure Anchor Point: Choose a strong, healthy branch to use as an anchor point for your climbing rope. The branch should be at least 6 inches in diameter and free from defects.
- Use a Prusik Hitch or Similar: A Prusik hitch (or other appropriate friction hitch) allows you to move the rope up and down the tree while maintaining a secure connection.
- Maintain 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 will help you maintain your balance and prevent falls.
- Move Slowly and Deliberately: Avoid sudden movements or jerky motions, which can destabilize you.
- Communicate with Ground Crew: If you are working with a ground crew, establish clear communication signals to ensure everyone is aware of your movements.
- Never Overreach: Avoid reaching too far, which can throw you off balance. Reposition yourself as needed to maintain a safe and comfortable working position.
- Lower Branches Carefully: When removing branches, lower them carefully to the ground to avoid injuring anyone below. Use ropes or rigging equipment as needed.
When NOT to Limb Walk:
- Unstable Trees: If the tree is unstable or shows signs of weakness, do not climb it.
- Adverse Weather Conditions: Avoid climbing in wet, windy, or icy conditions.
- Lack of Experience: If you are not experienced in tree climbing, seek professional training.
Personal Experience:
I once witnessed a fellow logger fall from a tree after losing his balance while limb walking. He wasn’t wearing a harness and suffered serious injuries. It was a stark reminder of the importance of safety when working in trees.
Data and Insights:
Falls from trees are a leading cause of injury in the logging industry. Studies have shown that wearing a climbing harness and using proper climbing techniques can significantly reduce the risk of falls. Proper training and experience are also essential for safe limb walking.
5. Brush Piles and Beyond: Efficient Cleanup and Wood Utilization
Pruning generates a significant amount of brush and wood. Efficient cleanup and utilization of this material are essential for maintaining a safe and tidy worksite, and for maximizing the value of the wood.
Cleanup Strategies:
- Dragging: For smaller branches and debris, dragging is a quick and efficient method of cleanup. Use a rope or chain to drag the material to a designated brush pile.
- Chipping: A wood chipper can be used to quickly reduce brush and small branches to mulch. This mulch can then be used for landscaping or composting. I have a PTO driven chipper that handles up to 6″ diameter material. It makes quick work of smaller branches.
- Loading and Hauling: For larger branches and logs, a loader or skid steer can be used to load the material onto a truck or trailer for hauling.
Wood Utilization:
- Firewood: Larger branches and logs can be cut and split into firewood. Seasoned firewood is a valuable resource for heating homes and cooking. Hardwoods like oak, maple, and birch are preferred for firewood due to their high BTU content.
- Lumber: Straight, knot-free logs can be milled into lumber. Lumber can be used for a variety of construction and woodworking projects. I’ve used white pine logs from pruning to build shelving in my shed.
- Craft Wood: Smaller branches and twigs can be used for craft projects, such as wreaths, baskets, and furniture.
- Composting: Smaller branches and twigs can be composted to create nutrient-rich soil amendment.
- Wildlife Habitat: Brush piles can provide valuable habitat for wildlife, such as birds, rabbits, and insects.
Creating Brush Piles:
- Location: Choose a location that is out of the way and does not pose a fire hazard.
- Size: Keep brush piles relatively small to prevent them from becoming breeding grounds for pests.
- Construction: Start with a base of larger branches and logs, and then gradually add smaller branches and debris.
- Burning: If you plan to burn the brush pile, check with your local authorities for any permits or restrictions.
Personal Experience:
I once had a large pile of brush and wood left over from a pruning project. Instead of burning it, I decided to use it to create a wildlife habitat. I piled the brush in a secluded corner of my property and was amazed at how quickly it became home to a variety of animals.
Data and Insights:
Efficient cleanup and wood utilization can significantly reduce the environmental impact of pruning projects. By recycling or reusing the wood, you can minimize waste and conserve valuable resources. Studies have shown that composting wood waste can improve soil health and reduce the need for synthetic fertilizers. These five hacks are the foundation for safe, efficient, and effective chainsaw pruning. Remember, practice makes perfect, and safety should always be your top priority. By mastering these techniques, you’ll be able to transform your pruning skills and create healthier, more beautiful trees. Now, grab your chainsaw, put on your PPE, and get to work! But always remember to think safety first.
