Mastering the Art of Felling with a 70cc Chainsaw
Felling a tree is a serious undertaking that requires careful planning, proper technique, and a healthy dose of respect for the power of nature. Here’s my step-by-step guide to felling trees safely and effectively with a 70cc chainsaw.
Step 1: Planning and Preparation
- Assess the Tree: Examine the tree for lean, wind direction, dead limbs, and any other potential hazards.
- Identify Escape Routes: Plan two escape routes at 45-degree angles away from the direction of the fall. Clear any obstacles from these routes.
- Clear the Work Area: Remove any brush, rocks, or other debris from around the base of the tree.
- Gather Your Tools: Ensure you have your chainsaw, wedges, felling axe, measuring tape, and safety gear.
Step 2: Making the Notch Cut
- Determine the Direction of Fall: The notch cut determines the direction in which the tree will fall.
- Cut the Upper Notch: Make a downward-angled cut into the tree, aiming for about one-third of the tree’s diameter.
- Cut the Lower Notch: Make an upward-angled cut to meet the upper notch, creating a wedge-shaped opening. Remove the wedge.
Step 3: Making the Back Cut
- Position Yourself: Stand to the side of the tree, opposite the notch.
- Start the Back Cut: Make a horizontal cut into the tree, slightly above the base of the notch. Leave a hinge of wood about 10% of the tree’s diameter. This hinge will help control the fall of the tree.
- Insert Wedges: As the back cut progresses, insert wedges into the cut to prevent the tree from pinching the saw and to help guide the fall.
- Final Cut: If necessary, make a final cut through the hinge to fell the tree. Be prepared to move quickly along your escape route as the tree falls.
Step 4: Post-Felling Procedures
- Assess the Situation: Once the tree has fallen, take a moment to assess the situation. Check for any hazards, such as spring poles or hung-up limbs.
- De-limb the Tree: Carefully remove the branches from the tree, starting from the base and working your way up.
- Buck the Tree: Cut the tree into manageable lengths for transport or processing.
Case Study: I once worked on a project where we needed to fell several large oak trees in a dense forest. The trees were leaning heavily in one direction, making the felling process particularly challenging. By carefully planning our cuts, using wedges effectively, and communicating clearly as a team, we were able to fell the trees safely and efficiently. The 70cc Stihl chainsaw proved invaluable in this project, providing the power and reliability we needed to tackle the tough oak wood.
Optimizing Firewood Preparation with Stihl’s 70cc Powerhouse
Firewood preparation can be a labor-intensive process, but with the right tools and techniques, it can be made much easier and more efficient. Here’s my guide to preparing firewood with a 70cc Stihl chainsaw.
Step 1: Bucking the Logs
- Choose a Safe Work Area: Select a level, stable area free from obstacles.
- Support the Logs: Use sawbucks or other supports to raise the logs off the ground. This will make cutting easier and safer.
- Cut the Logs to Length: Determine the desired length of your firewood and cut the logs accordingly. A common length is 16 inches, but you may need to adjust this based on the size of your wood stove or fireplace.
- Use Proper Technique: Maintain a firm grip on the chainsaw and use a smooth, controlled cutting motion. Avoid forcing the saw.
Step 2: Splitting the Wood
- Choose a Splitting Method: There are several ways to split wood, including using a splitting axe, maul, or hydraulic log splitter.
- Splitting Axe or Maul: Place the log on a chopping block and swing the axe or maul with a controlled motion. Aim for the center of the log or any visible cracks.
- Hydraulic Log Splitter: Place the log on the splitter and activate the hydraulic ram to split the wood. This is a much faster and easier method for splitting large volumes of wood.
Step 3: Stacking the Firewood
- Choose a Sunny, Windy Location: This will help the firewood dry more quickly.
- Elevate the Stack: Place the firewood on pallets or other supports to keep it off the ground.
- Stack the Wood Loosely: Allow for good air circulation between the logs.
- Cover the Top of the Stack: This will protect the wood from rain and snow.
Wood Species and Firewood Quality
The type of wood you use for firewood can significantly impact its heating value and burning characteristics. Here’s a breakdown of some common wood species and their suitability for firewood:
- Hardwoods: Generally produce more heat and burn longer than softwoods.
- Oak: Excellent heat output, long burn time, but can be difficult to split.
- Maple: Good heat output, easy to split, but can produce more smoke than oak.
- Ash: Good heat output, easy to split, and burns cleanly.
- Beech: Excellent heat output, long burn time, but can be difficult to dry.
- Softwoods: Burn quickly and produce less heat than hardwoods.
- Pine: Easy to ignite, burns quickly, but produces a lot of smoke and creosote.
- Fir: Similar to pine, but burns slightly cleaner.
- Spruce: Burns quickly and produces a lot of sparks.
Data Point: Seasoned oak firewood can have a heating value of up to 28 million BTU per cord, while seasoned pine firewood may only have a heating value of around 18 million BTU per cord.
Seasoning Firewood: The Key to Efficient Burning
Seasoning firewood is the process of drying the wood to reduce its moisture content. Green wood (freshly cut wood) can have a moisture content of 50% or more, while seasoned firewood should have a moisture content of 20% or less. Seasoning firewood improves its heating value, reduces smoke production, and makes it easier to ignite.
- Drying Time: The time it takes to season firewood depends on the wood species, climate, and stacking method. Generally, hardwoods require at least 6-12 months of seasoning, while softwoods may only require 3-6 months.
- Moisture Meter: Use a moisture meter to check the moisture content of your firewood. This will help you determine when it is properly seasoned.
- Optimal Moisture Content: Aim for a moisture content of 15-20% for best burning performance.
