Stihl MS 250 vs 251 Chainsaws (5 Pro Tips for Efficiency)

Endurance is the name of the game when you’re wrestling with wood, whether you’re felling trees in the backwoods or stacking firewood for the winter. I’ve spent years honing my skills in timber processing, and there’s nothing quite like the satisfaction of turning raw timber into a neatly stacked pile of firewood, ready to warm a home through the coldest months. The heart of many wood processing operations, especially for smaller scale or home use, often comes down to choosing the right chainsaw. Today, I’m diving deep into a comparison that’s been on the minds of many: the Stihl MS 250 vs. the MS 251. Plus, I’m going to give you my top five pro tips for maximizing efficiency with either of these workhorses.

But first, let’s set the stage. The global firewood market is projected to reach a staggering \$2.6 billion by 2027, according to a recent report by Global Industry Analysts Inc. This shows that even in our increasingly digital world, the demand for good old-fashioned firewood remains strong. Whether it’s for heating homes, cooking, or simply enjoying a cozy fire, firewood is a staple for many. Meanwhile, the logging industry, vital for timber production, faces increasing pressure to adopt sustainable practices. The Forest Stewardship Council (FSC) reports a growing demand for certified sustainable wood products, with certified forests now covering over 200 million hectares worldwide.

Stihl MS 250 vs. MS 251: A Head-to-Head Showdown

Both the Stihl MS 250 and MS 251 are popular choices for homeowners, farmers, and even some professional users. They’re known for their reliability, ease of use, and reasonable price point. But which one comes out on top? Let’s break it down.

Engine Power and Performance

The heart of any chainsaw is its engine. The MS 250 features a 45.4 cc engine, while the MS 251 boasts a slightly larger 45.6 cc engine. On paper, the difference seems negligible, but in practice, it can translate to a bit more torque and cutting power, especially when dealing with tougher wood.

• MS 250: 3.0 bhp (2.2 kW)
• MS 251: 3.0 bhp (2.3 kW)

While the horsepower is the same, the MS 251 delivers that power more efficiently, particularly in demanding cuts.

Weight and Handling

Weight is a crucial factor, especially when you’re spending hours in the woods. The MS 250 is slightly lighter, weighing in at around 10.1 lbs (without the bar and chain), compared to the MS 251’s 10.8 lbs. That might not sound like much, but over a long day, it can make a noticeable difference in fatigue.

Both saws are well-balanced and easy to handle, making them suitable for a variety of users. However, the MS 250’s lighter weight might make it a better choice for those who prioritize maneuverability and ease of use.

Features and Technology

Here’s where the MS 251 really starts to shine. It incorporates some of Stihl’s newer technologies, such as the pre-separation air filtration system. This system removes larger debris before it reaches the air filter, extending the filter’s life and reducing maintenance.

The MS 251 also features Stihl’s Easy2Start™ system, which makes starting the saw much easier, requiring less pulling force. This is a huge plus, especially in cold weather or for those with limited strength.

Durability and Maintenance

Both saws are built to last, but proper maintenance is key to maximizing their lifespan. Regular cleaning, sharpening, and lubrication are essential for both models. The MS 251’s pre-separation air filtration system can reduce the frequency of air filter cleaning, saving you time and effort.

Parts availability is also good for both saws, making repairs relatively straightforward. However, the MS 251’s newer technology might mean that some parts are slightly more expensive.

Cost

The MS 250 is generally a bit more affordable than the MS 251. However, the price difference is usually not significant, and the MS 251’s added features and performance might make it worth the extra investment.

5 Pro Tips for Chainsaw Efficiency

Now that we’ve compared the two saws, let’s get into the nitty-gritty of how to maximize your efficiency, no matter which model you choose. These tips are born from years of experience, and they’ll help you cut faster, safer, and with less effort.

1. Master the Art of Chain Sharpening

A sharp chain is the single most important factor in chainsaw efficiency. A dull chain will not only cut slower but also put more strain on the engine and increase the risk of kickback.

I remember one particularly frustrating day when I was trying to fell a large oak tree with a dull chain. The saw was struggling, the wood was smoking, and I was getting nowhere fast. After finally taking the time to properly sharpen the chain, the difference was night and day. The saw sliced through the wood like butter, and the whole process became much easier and safer.

• Tools: You’ll need a chainsaw file, a file guide, and a depth gauge tool. A chainsaw vise can also be helpful for holding the saw steady.
• Technique: Use the file guide to maintain the correct angle and depth. File each tooth evenly, using smooth, consistent strokes. Check the depth gauge and file it down if necessary.
• Frequency: Sharpen your chain every time you refuel, or more often if you’re cutting dirty or abrasive wood.

There are several types of chainsaw sharpeners available, ranging from simple hand files to electric sharpeners. While hand filing takes practice, it gives you the most control and allows you to customize the sharpness of each tooth. Electric sharpeners are faster and easier to use, but they can sometimes remove too much material.

A study by Oregon Products found that a properly sharpened chain can increase cutting speed by up to 30% and reduce fuel consumption by up to 20%.

2. Choose the Right Bar and Chain

The bar and chain you use can have a significant impact on your chainsaw’s performance. Consider the type of wood you’ll be cutting, the size of the logs, and your own experience level when making your selection.

• Bar Length: A longer bar allows you to cut larger logs, but it also adds weight and can make the saw more difficult to control. A shorter bar is easier to maneuver and is better suited for smaller jobs. As a general rule, choose a bar that is slightly longer than the diameter of the largest logs you’ll be cutting.
• Chain Type: There are several types of chainsaw chains available, each designed for different applications.
  • Full Chisel Chains: These chains have square-cornered teeth that cut aggressively and are ideal for clean wood. However, they are more prone to damage if they come into contact with dirt or rocks.
  • Semi-Chisel Chains: These chains have rounded-cornered teeth that are more durable and forgiving than full chisel chains. They are a good choice for cutting dirty or abrasive wood.
  • Low-Profile Chains: These chains have a reduced kickback tendency and are a good choice for beginners or those who prioritize safety.

I once made the mistake of trying to cut through a pile of old, dirty logs with a full chisel chain. The chain dulled almost instantly, and I spent more time sharpening than cutting. After switching to a semi-chisel chain, the job became much easier and faster.

3. Master Felling Techniques

Felling a tree safely and efficiently is a skill that takes practice and knowledge. Before you even think about starting your saw, take the time to assess the tree, the surrounding area, and the potential hazards.

• Planning: Determine the tree’s natural lean and the direction you want it to fall. Clear the area around the tree of any obstacles and create a clear escape path.
• Notch Cut: Make a notch cut on the side of the tree facing the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
• Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood to control the direction of the fall.
• Felling: Use wedges if necessary to help guide the tree’s fall. As the tree starts to fall, move quickly and safely away from the area.

I’ve learned the hard way that rushing the felling process can lead to disaster. One time, I misjudged the tree’s lean and it fell in the wrong direction, narrowly missing my truck. Now, I always take my time and double-check everything before making the first cut.

OSHA (Occupational Safety and Health Administration) provides detailed guidelines for safe tree felling practices. Familiarize yourself with these guidelines before attempting to fell a tree.

4. Optimize Your Bucking and Splitting Techniques

Once you’ve felled the tree, the next step is to buck it into manageable lengths and split the logs for firewood. Efficient bucking and splitting can save you a lot of time and energy.

• Bucking: Use a sawbuck or log stand to elevate the logs and make them easier to cut. Cut the logs into lengths that are appropriate for your fireplace or wood stove.
• Splitting: Use a splitting axe or maul to split the logs. Aim for the natural cracks and splits in the wood. If you’re having trouble splitting a log, try rotating it 90 degrees or using a splitting wedge.

I’ve found that splitting wood is much easier when the wood is green. Green wood is softer and more pliable than seasoned wood, making it easier to split. However, green wood also takes longer to dry.

A study by the University of Maine found that splitting wood with a hydraulic log splitter can reduce the amount of physical exertion by up to 75% compared to splitting with an axe or maul.

5. Proper Chainsaw Maintenance

Regular maintenance is essential for keeping your chainsaw running smoothly and extending its lifespan. Neglecting maintenance can lead to costly repairs and reduced performance.

• Cleaning: Clean your chainsaw after each use. Remove any sawdust or debris from the engine, air filter, and bar.
• Lubrication: Keep the chain and bar properly lubricated. Use a high-quality bar and chain oil.
• Air Filter: Clean or replace the air filter regularly. A dirty air filter can restrict airflow and cause the engine to overheat.
• Spark Plug: Check the spark plug regularly and replace it if necessary.
• Fuel: Use fresh, high-quality fuel. Store fuel in a clean, airtight container.

I once made the mistake of neglecting to clean the air filter on my chainsaw. The engine started running poorly, and eventually, it seized up completely. The repair cost me several hundred dollars and a lot of downtime. Now, I make sure to clean the air filter after every use.

Different species have different densities, moisture contents, and burning characteristics. Understanding these differences can help you choose the best wood for your needs.

• Hardwoods: Hardwoods are denser than softwoods and burn longer and hotter. They are generally the best choice for firewood. Examples of hardwoods include oak, maple, ash, and birch.
• Softwoods: Softwoods are less dense than hardwoods and burn faster and cooler. They are often used for kindling or starting fires. Examples of softwoods include pine, fir, and spruce.

The moisture content of firewood is also crucial. Green wood contains a lot of moisture, which makes it difficult to light and causes it to burn inefficiently. Seasoned wood, on the other hand, has been dried to a moisture content of 20% or less. Seasoned wood lights easily, burns hot, and produces less smoke.

• Seasoning Time: The amount of time it takes to season firewood depends on the species of wood, the climate, and the size of the logs. As a general rule, hardwoods take at least six months to season, while softwoods take at least three months.

I’ve found that stacking firewood in a sunny, well-ventilated area can significantly speed up the seasoning process. Cover the top of the stack to protect it from rain and snow, but leave the sides open to allow for air circulation.

A study by the USDA Forest Service found that seasoned firewood can produce up to 25% more heat than green firewood.

Costs, Budgeting, and Resource Management

Wood processing and firewood preparation can be a costly endeavor, especially if you’re starting from scratch. It’s important to carefully consider your budget and manage your resources effectively.

• Chainsaw: A good quality chainsaw can cost anywhere from \$200 to \$1000 or more, depending on the size and features.
• Safety Gear: Safety gear, such as a helmet, eye protection, ear protection, gloves, and chaps, can cost around \$100 to \$200.
• Tools: Tools, such as a splitting axe, maul, wedges, and sawbuck, can cost around \$100 to \$300.
• Fuel and Oil: Fuel and oil can cost around \$20 to \$50 per month, depending on how much you use your chainsaw.
• Maintenance: Maintenance costs, such as sharpening, repairs, and replacement parts, can vary depending on the frequency of use and the quality of the equipment.

One way to save money is to buy used equipment. You can often find good deals on used chainsaws, axes, and other tools at garage sales, flea markets, and online marketplaces. However, be sure to inspect the equipment carefully before you buy it to make sure it’s in good working condition.

Troubleshooting and Common Pitfalls

Even with the best equipment and techniques, you’re bound to encounter some challenges along the way. Here are some common pitfalls to avoid and tips for troubleshooting problems.

• Chainsaw Won’t Start: Check the fuel, spark plug, and air filter. Make sure the choke is in the correct position.
• Chainsaw Runs Poorly: Clean or replace the air filter. Check the spark plug. Make sure the fuel is fresh.
• Chain Dulls Quickly: Use the correct chain for the type of wood you’re cutting. Sharpen the chain regularly.
• Wood is Difficult to Split: Try splitting the wood when it’s green. Use a splitting wedge. Rotate the log 90 degrees.
• Tree Falls in the Wrong Direction: Carefully assess the tree’s lean and the surrounding area before felling it. Use wedges to guide the tree’s fall.

I once spent hours trying to start a chainsaw that wouldn’t fire up. After checking everything I could think of, I finally realized that the fuel was old and stale. Once I replaced the fuel with fresh gas, the saw started right up.

Real Examples and Case Studies

Let’s take a look at some real-world examples of successful firewood preparation and timber processing projects.
