Understanding the 20-Inch Chainsaw Advantage

A 20-inch chainsaw strikes a sweet spot for many wood processing tasks. It’s powerful enough to handle medium-sized trees and logs, yet still maneuverable enough for limbing and smaller jobs. Before diving into my top picks, let’s explore why this size is so popular.

The Versatility Factor

I’ve found that a 20-inch bar length offers a good balance between cutting capacity and weight. It allows you to fell trees with a diameter up to about 36 inches (remember, you can cut from both sides), which covers a significant portion of the trees you’ll encounter in most residential or hobby logging situations.

Beyond felling, a 20-inch chainsaw is excellent for bucking logs into firewood lengths, removing limbs, and even some milling applications. It’s a true all-rounder.

Power to Weight Ratio

When choosing a chainsaw, power is crucial, but so is weight. A heavier saw will fatigue you faster, reducing your efficiency and increasing the risk of accidents. 20-inch chainsaws typically offer a good power-to-weight ratio, allowing you to work for extended periods without excessive strain.

Considering Alternatives

Of course, a 20-inch chainsaw isn’t always the perfect choice. For very small tasks, like pruning small branches, a smaller saw might be more appropriate. Conversely, for felling large trees consistently, a larger, more powerful saw with a longer bar might be necessary. Consider the types of wood processing you’ll be doing most often when making your decision.

Key Features to Consider When Choosing a 20-Inch Chainsaw

Before I reveal my top picks, let’s discuss the key features I consider when evaluating a chainsaw. These factors will help you understand my choices and make your own informed decision.

Engine Power and Type

The engine is the heart of any chainsaw. You’ll typically find two types: two-stroke gasoline engines and battery-powered electric motors.

Two-Stroke Gasoline Engines: These are the traditional choice for chainsaws, offering high power and long run times. They require a mix of gasoline and oil and can be a bit noisy and require more maintenance. Look for engines with at least 50cc displacement for adequate power in a 20-inch chainsaw.
Battery-Powered Electric Motors: These are becoming increasingly popular due to their quiet operation, ease of use, and lack of emissions. Battery technology has improved significantly, allowing for decent run times and power comparable to some gasoline models. Consider the battery voltage and amp-hour (Ah) rating, as these determine the power and run time.

I’ve used both types extensively. While I appreciate the convenience of electric chainsaws for smaller jobs, I still prefer the raw power and extended run time of a gasoline-powered saw for demanding tasks like felling larger trees.

Bar and Chain Quality

The bar and chain are critical for cutting performance. Look for bars made from high-quality steel with a durable sprocket tip. The chain should be sharp and well-maintained for efficient cutting.

Chain Type: Different chain types are designed for different purposes. Full chisel chains are aggressive and fast-cutting but require more sharpening skill. Semi-chisel chains are more forgiving and stay sharp longer, making them a good choice for general use.
Chain Pitch and Gauge: These measurements determine the chain’s size and compatibility with the bar and sprocket. Ensure the chain pitch and gauge match the specifications of your chainsaw.

I always recommend investing in high-quality chains and sharpening them regularly. A sharp chain makes a world of difference in cutting speed, efficiency, and safety.

Ergonomics and Handling

A chainsaw should be comfortable to hold and easy to maneuver. Consider the following:

Weight: As mentioned earlier, weight is a crucial factor. Choose a saw that you can comfortably handle for extended periods.
Handle Design: Look for a chainsaw with ergonomic handles that provide a secure and comfortable grip.
Vibration Reduction: Chainsaws can generate significant vibration, which can lead to fatigue and even long-term health problems. Look for models with effective vibration reduction systems.

I’ve learned the hard way that ergonomics matter. I once used a poorly designed chainsaw for an entire day, and my hands were numb for days afterward.

Safety Features

Safety should always be your top priority when using a chainsaw. Look for the following safety features:

Chain Brake: This is a critical safety feature that stops the chain immediately in case of kickback.
Throttle Lockout: This prevents accidental throttle engagement.
Chain Catcher: This catches the chain if it breaks or comes off the bar.
Hand Guards: These protect your hands from debris and the chain.

Never operate a chainsaw without proper safety gear, including a helmet, eye protection, hearing protection, gloves, and chaps.

Maintenance and Reliability

A chainsaw is a machine that requires regular maintenance to keep it running smoothly. Consider the following:

Ease of Maintenance: Look for a chainsaw that is easy to clean, lubricate, and sharpen.
Availability of Parts: Ensure that replacement parts are readily available for your chosen model.
Warranty: A good warranty can provide peace of mind and protect you from unexpected repairs.

I always keep a spare chain, spark plug, and air filter on hand to minimize downtime during wood processing projects.

Wood Anatomy and Properties: A Deeper Dive

Understanding the anatomy and properties of wood is crucial for efficient and safe wood processing. Different wood species have different characteristics that affect how they cut, split, and burn.

Hardwood vs. Softwood

The terms “hardwood” and “softwood” refer to the type of tree the wood comes from, not necessarily its actual hardness. Hardwoods are typically deciduous trees with broad leaves, while softwoods are typically coniferous trees with needles.

Hardwoods: Generally denser and harder than softwoods. They burn longer and produce more heat, making them ideal for firewood. Examples include oak, maple, and ash.
Softwoods: Generally less dense and easier to cut than hardwoods. They are often used for construction and paper production. Examples include pine, fir, and spruce.

I’ve found that hardwoods require more power to cut and split than softwoods, but the extra effort is worth it for the superior firewood they produce.

Wood Grain and Density

The grain of wood refers to the arrangement of wood fibers. Straight-grained wood is easier to split than wood with knots or irregular grain. Density is a measure of how much mass is contained in a given volume of wood. Denser wood is generally stronger and more durable.

Moisture Content

Moisture content is the amount of water in wood, expressed as a percentage of the wood’s dry weight. Freshly cut (“green”) wood can have a moisture content of 50% or more. Seasoned firewood should have a moisture content of 20% or less.

Why Season Firewood? Burning green wood is inefficient and produces a lot of smoke and creosote, which can be a fire hazard in your chimney. Seasoning firewood allows the moisture to evaporate, resulting in cleaner, more efficient burning.
Seasoning Time: The amount of time it takes to season firewood depends on the wood species, climate, and stacking method. Generally, hardwoods require at least six months to a year of seasoning, while softwoods may season in as little as three months.

I always use a moisture meter to check the moisture content of my firewood before burning it. It’s a simple and effective way to ensure that I’m burning dry, seasoned wood.

Logging Tool Selection and Maintenance Best Practices

A chainsaw is just one tool in the wood processor’s arsenal. Other essential tools include axes, splitting mauls, wedges, and peaveys.

Axes and Splitting Mauls

Axes are used for felling small trees, limbing, and splitting small pieces of wood. Splitting mauls are heavier and designed specifically for splitting logs.

Axe Types: Felling axes have a long, thin blade for cutting across the grain of wood. Splitting axes have a shorter, wider blade for splitting wood along the grain.
Splitting Maul Weight: Choose a splitting maul weight that you can comfortably swing for extended periods. A heavier maul will split wood more easily, but it will also be more tiring to use.

I prefer using a splitting maul for most of my firewood splitting. It’s more efficient and safer than using an axe for larger logs.

Wedges and Peaveys

Wedges are used to split particularly tough or knotty logs. They are driven into the wood with a sledgehammer. Peaveys are used to roll and position logs.

Wedge Types: Steel wedges are durable and effective for splitting most types of wood. Aluminum wedges are lighter and less likely to spark, making them a good choice for working in areas with dry vegetation.
Peavey Size: Choose a peavey size that is appropriate for the size of logs you will be handling.

I always keep a few wedges on hand for those stubborn logs that refuse to split with a maul.

Tool Maintenance

Proper tool maintenance is essential for safety and efficiency. Keep your tools clean, sharp, and well-lubricated.

Sharpening: Sharpen your axes and mauls regularly with a file or sharpening stone.
Cleaning: Clean your tools after each use to remove dirt and debris.
Lubrication: Lubricate moving parts to prevent rust and corrosion.

I make it a habit to sharpen my tools at the end of each workday. It only takes a few minutes, and it makes a big difference in performance.

Firewood Seasoning Techniques and Safety Considerations

Seasoning firewood properly is crucial for safe and efficient burning. Here are some tips for seasoning firewood:

Stacking Methods

The way you stack your firewood can significantly affect the seasoning process.

Elevated Stacks: Stack your firewood on pallets or skids to keep it off the ground and allow for better air circulation.
Loose Stacks: Leave space between the logs in your stacks to allow for air to circulate freely.
Covered Stacks: Cover the top of your stacks with a tarp or roofing material to protect the wood from rain and snow.

I prefer to stack my firewood in long rows with spaces between the logs. I also cover the top of the stacks with old roofing tin to keep the rain out.

Location

Choose a location for your firewood stacks that is sunny and well-ventilated. Avoid stacking firewood near your house or other structures, as it can attract insects and rodents.

Safety Considerations

Wear Gloves: Wear gloves when handling firewood to protect your hands from splinters and dirt.
Lift Properly: Lift firewood with your legs, not your back, to avoid injury.
Watch for Insects and Animals: Be aware of insects and animals that may be living in your firewood.

I once got a nasty splinter from handling firewood without gloves. Now I always wear gloves and am careful to lift properly.

Project Planning and Execution: A Case Study

Let’s walk through a case study to illustrate how to plan and execute a wood processing project using a 20-inch chainsaw.

Project Goal

The goal of this project is to fell a dead oak tree, buck it into firewood lengths, split the wood, and season it for burning next winter.

Step 1: Assessment

I start by assessing the tree and the surrounding area. I check for any hazards, such as power lines, buildings, or other trees that could be damaged during felling. I also determine the best direction to fell the tree.

Step 2: Preparation

Next, I gather my tools and safety gear. This includes my 20-inch chainsaw, axe, splitting maul, wedges, peavey, helmet, eye protection, hearing protection, gloves, and chaps. I also make sure my chainsaw is properly fueled and oiled.

Step 3: Felling

I carefully fell the tree, using proper felling techniques to ensure it lands in the desired location.

Step 4: Bucking

Once the tree is on the ground, I buck it into firewood lengths using my chainsaw. I typically cut the logs into 16-inch lengths, which are ideal for my wood stove.

Step 5: Splitting

After bucking the logs, I split them using my splitting maul and wedges. I split the logs into pieces that are small enough to fit easily into my wood stove.

Step 6: Stacking

Finally, I stack the split firewood in a sunny and well-ventilated location. I elevate the stacks on pallets and cover the top with roofing tin.

Step 7: Seasoning

I allow the firewood to season for at least six months before burning it. I use a moisture meter to check the moisture content before burning.

Unique Insights and Data-Backed Content

Here are some unique insights and data-backed content related to wood processing:

Wood Moisture Content Dynamics

The rate at which wood dries depends on several factors, including the wood species, the size of the wood, the climate, and the stacking method.

Data Point: A study by the University of Wisconsin found that oak firewood seasoned in a covered stack lost an average of 2% moisture content per month.
Insight: Covering your firewood stacks can significantly reduce the seasoning time.

Timber Quality and Tool Mechanics

The quality of timber can affect the performance of your tools.

Data Point: Knots in wood can increase the force required to split it by up to 50%.
Insight: When splitting knotty wood, use wedges and a sledgehammer to avoid damaging your splitting maul.

Firewood Seasoning Techniques and Fuel Value Ratings
