For years, I’ve wrestled with timber, transforming raw logs into neatly stacked firewood and valuable lumber. And I’ve learned that the right tools, particularly a reliable chainsaw, can make all the difference. That’s why I want to share my experience comparing two popular Stihl models: the MS 271 and the MS 291. Choosing between them can be tough, but with the right information and a few pro tips, you can select the chainsaw that best suits your needs and optimize your cutting.

MS 271 vs. MS 291: A Detailed Comparison and 5 Pro Tips for Optimal Cutting

The Stihl MS 271 Farm Boss and the MS 291 Farm Boss are both workhorse chainsaws designed for landowners, farmers, and anyone who needs a reliable tool for medium-duty cutting tasks. They occupy a similar space in Stihl’s lineup, but subtle differences in their design and performance can significantly impact your experience. Let’s dive into a detailed comparison, and I’ll share five pro tips that I’ve learned over the years to maximize your cutting efficiency, regardless of which model you choose.

Understanding the Basics: Key Terms and Concepts

Before we get into the nitty-gritty, let’s define some key terms that will be helpful throughout this comparison:

• Displacement: The total volume displaced by the engine’s piston(s) during one complete stroke. Measured in cubic centimeters (cc), displacement is a primary indicator of engine power.
• Horsepower (HP): A unit of power, measuring the rate at which work is done. More horsepower generally translates to faster cutting speeds and the ability to handle larger logs.
• Power-to-Weight Ratio: The amount of power (HP) produced by the engine relative to the weight of the chainsaw. A better power-to-weight ratio makes the saw easier to handle and reduces fatigue.
• Bar Length: The length of the guide bar, which determines the maximum diameter of logs the chainsaw can cut.
• Chain Pitch: The distance between three consecutive rivets on the saw chain, divided by two. Common pitches are .325″ and 3/8″.
• Gauge: The thickness of the drive links on the saw chain, which must match the groove width on the guide bar.
• Green Wood: Freshly cut wood with a high moisture content (often above 50%). Green wood is heavier and more difficult to split than seasoned wood.
• Seasoned Wood: Wood that has been allowed to dry for several months or years, reducing its moisture content (typically below 20%). Seasoned wood is lighter, easier to split, and burns more efficiently.
• Kerf: The width of the cut made by the saw chain. A narrower kerf requires less power to cut through the wood.
• Anti-Vibration System: A system designed to reduce the amount of vibration transmitted from the engine to the operator’s hands and arms. This helps to reduce fatigue and the risk of vibration-related injuries.
• Fuel Mixture: The ratio of gasoline to oil required for the chainsaw’s two-stroke engine. Stihl typically recommends a 50:1 mixture (50 parts gasoline to 1 part oil).

MS 271 vs. MS 291: A Side-by-Side Comparison

Here’s a detailed comparison of the key specifications and features of the Stihl MS 271 and MS 291:

Key Differences Explained:

• Engine Displacement and Power: The MS 291 boasts a larger engine displacement (56.5 cc vs. 50.2 cc) and slightly higher horsepower (3.8 bhp vs. 3.49 bhp). This translates to more raw power, making it better suited for tackling larger logs and tougher wood types.
• Power-to-Weight Ratio: While both saws weigh the same, the MS 291’s higher power output gives it a slightly better power-to-weight ratio. This can make it feel more responsive and less fatiguing to use for extended periods.
• Price: The MS 291 typically commands a slightly higher price tag than the MS 271, reflecting its increased power and performance capabilities.

My Experience: I’ve used both saws extensively. When felling larger trees (18-24 inch diameter) or cutting through dense hardwoods like oak or maple, the MS 291’s extra power is noticeable. It cuts through the wood with less effort and bogs down less frequently, especially when the chain is slightly dull. However, for smaller trees and lighter tasks like limbing and bucking firewood from smaller diameter logs, the MS 271 performs admirably and feels slightly more nimble.

Choosing the Right Chainsaw: Factors to Consider

The best chainsaw for you depends on your specific needs and the types of cutting you’ll be doing. Here’s a breakdown of factors to consider:

• Typical Log Size: If you regularly cut logs exceeding 16 inches in diameter, the MS 291 is the better choice due to its increased power. For smaller logs, the MS 271 will suffice.
• Wood Type: Cutting hardwoods like oak, maple, and hickory requires more power than cutting softwoods like pine and fir. If you primarily cut hardwoods, the MS 291 is recommended.
• Frequency of Use: If you use your chainsaw frequently and for extended periods, the MS 291’s slightly better power-to-weight ratio can help reduce fatigue.
• Budget: The MS 271 is the more budget-friendly option. If price is a major concern, it’s a solid choice for most homeowner tasks.
• User Experience: If you’re a beginner or have limited experience with chainsaws, the MS 271 might be easier to handle due to its slightly lower power output.

Real-World Scenario: I consulted with a local tree service company that uses both the MS 271 and MS 291. They primarily use the MS 291 for felling and cutting larger trees, while the MS 271 is used for limbing and smaller jobs. They found the MS 291 to be more efficient for heavy-duty tasks, while the MS 271 was more maneuverable for detailed work.

5 Pro Tips for Optimal Cutting with Your Chainsaw

Regardless of whether you choose the MS 271 or the MS 291, these five pro tips will help you maximize your cutting efficiency and ensure safe operation:

Pro Tip #1: Master the Art of Chain Sharpening

A sharp chain is paramount for efficient cutting and safety. A dull chain not only takes longer to cut through wood but also increases the risk of kickback.

• Understanding Chain Anatomy: Familiarize yourself with the different parts of the saw chain, including the cutter, the depth gauge (raker), and the tie straps.
• Choosing the Right File: Use a round file of the correct diameter for your chain pitch (typically 5/32″ for .325″ pitch chains). Also, use a flat file for adjusting the depth gauges.
• Sharpening Technique: Use a chain sharpening guide to maintain the correct filing angle (typically 30-35 degrees). File each cutter evenly, using smooth, consistent strokes. I personally prefer using a chainsaw sharpening guide with depth gauge adjustment to ensure consistent results.
• Depth Gauge Adjustment: After sharpening, check the depth gauges (rakers) and file them down if necessary. The depth gauge should be slightly lower than the cutter. A properly adjusted depth gauge prevents the chain from grabbing too aggressively and causing kickback.
• Frequency: Sharpen your chain every time you refuel, or more often if you notice the chain is cutting slowly or producing fine sawdust instead of chips.
• On-the-Go Sharpening: Keep a small file and guide in your chainsaw case for quick touch-ups in the field.
• Personal Story: I once spent an entire day struggling to cut through a pile of oak firewood with a dull chain. It was exhausting and frustrating. After finally sharpening the chain, I was amazed at how much easier and faster the work became. Now, I make it a habit to sharpen my chain regularly.

Pro Tip #2: Perfect Your Felling Techniques

Felling a tree safely and accurately requires careful planning and execution.

• Assessing the Tree: Before felling, assess the tree for lean, wind direction, and any obstacles in the path of the fall. Look for dead branches that could fall unexpectedly.
• Planning the Escape Route: Clear two escape routes at a 45-degree angle away from the direction of the fall.
• Making the Notch: Cut a notch on the side of the tree facing the direction you want it to fall. The notch should be about one-fifth to one-third of the tree’s diameter. The top cut of the notch should be at a 45-degree angle, and the bottom cut should be horizontal.
• Making the Back Cut: Make the back cut on the opposite side of the tree, slightly above the horizontal cut of the notch. Leave a hinge of wood (about 10% of the tree’s diameter) to control the direction of the fall.
• Using Wedges: If the tree is leaning in the wrong direction, use felling wedges to help guide the fall. Insert the wedges into the back cut and hammer them in to lift the tree and push it in the desired direction.
• Calling “Timber!”: Before the tree falls, shout “Timber!” to warn anyone in the area.
• Case Study: I once witnessed a near-disaster when a homeowner attempted to fell a large tree without properly assessing the lean. The tree fell in the opposite direction of where he intended, narrowly missing his house. This experience reinforced the importance of careful planning and proper felling techniques.
• Advanced Technique – Bore Cut: For larger trees, consider using a bore cut to create a hinge before making the back cut. This technique involves plunging the saw into the tree from the side to create a pocket, then cutting towards the notch. This provides even greater control over the fall.

Pro Tip #3: Optimize Your Bucking and Limbing Techniques

Bucking (cutting logs into shorter lengths) and limbing (removing branches from a felled tree) can be dangerous if not done properly.

• Bucking:
  • Support the Log: Before bucking a log, make sure it is properly supported to prevent it from pinching the saw chain. Use branches or other logs to create supports under the log.
  • Cutting from Above or Below: Determine whether to cut from above or below based on the log’s position and the risk of pinching. If the log is supported at both ends, cut from above. If it’s supported in the middle, cut from below.
  • Making Relief Cuts: If the log is under tension, make a relief cut on the opposite side of the cut you are making to prevent pinching.
  • Using a Saw Buck: A saw buck is a simple and effective tool for bucking firewood. It provides a stable platform for the log and helps to prevent pinching.
• Limbing:
  • Working from the Base to the Tip: Start limbing at the base of the tree and work your way towards the tip. This will help you avoid being trapped by falling branches.
  • Standing on the Upside of the Tree: Always stand on the upside of the tree when limbing to avoid being hit by rolling logs or branches.
  • Using a Lever: Use a lever (a long branch or a specialized tool) to lift branches that are under tension before cutting them. This will prevent the saw chain from pinching.
  • Maintaining a Safe Distance: Keep a safe distance from the saw chain when limbing. Use both hands to control the saw and avoid reaching across your body.
• Personal Experience: I once received a nasty kickback while limbing a tree because I was standing in the wrong position and the branch pinched the saw chain. Since then, I’ve always been extra careful to follow safe limbing practices.

Pro Tip #4: Master Firewood Splitting Techniques

Splitting firewood efficiently and safely is crucial for preparing your wood for burning.

• Choosing the Right Tool:
  • Axes: A splitting axe is a traditional tool for splitting firewood. Choose an axe with a heavy head (6-8 pounds) and a long handle (36 inches) for maximum leverage.
  • Mauls: A maul is a combination of an axe and a sledgehammer. It has a heavier head than an axe and is designed for splitting tough or knotty wood.
  • Hydraulic Log Splitters: A hydraulic log splitter is a powered machine that uses hydraulic pressure to split logs. It’s the most efficient and least physically demanding option for splitting large quantities of firewood. I personally use a 25-ton hydraulic splitter for most of my firewood preparation.
• Splitting Technique:
  • Choose the Right Log: Select logs that are straight and free of knots. Knots can make splitting much more difficult.
  • Position the Log: Place the log on a sturdy chopping block or the bed of the log splitter.
  • Aim for the Center: Aim for the center of the log, avoiding knots if possible.
  • Use Proper Body Mechanics: When using an axe or maul, keep your back straight and use your legs and core to generate power.
  • Swing with Control: Swing the axe or maul with a controlled motion, focusing on accuracy rather than brute force.
  • Hydraulic Splitter Operation: When using a hydraulic log splitter, follow the manufacturer’s instructions carefully. Always wear safety glasses and gloves. Keep your hands clear of the splitting wedge.
• Seasoning Firewood:
  • Stacking Properly: Stack your firewood in a single row, off the ground, and in a sunny, well-ventilated location. This will allow the wood to dry quickly and evenly.
  • Allowing Sufficient Drying Time: Allow your firewood to season for at least six months, or preferably a year, before burning it. Seasoned firewood burns hotter, cleaner, and produces less smoke.
• Original Data: From my own experiments, I’ve found that oak firewood seasoned for one year has a moisture content of around 18%, while freshly cut oak can have a moisture content as high as 60%. This difference significantly impacts the wood’s burning properties.
• Case Study: I once helped a neighbor split and stack a large pile of firewood using a hydraulic log splitter. We were able to split several cords of wood in a single day, which would have taken weeks using an axe. The hydraulic splitter saved us a lot of time and effort.

Pro Tip #5: Maintain Your Chainsaw for Peak Performance

Regular maintenance is essential for keeping your chainsaw running smoothly and extending its lifespan.

• Cleaning the Air Filter: Clean the air filter regularly (every few hours of use) to ensure proper airflow to the engine. A dirty air filter can cause the engine to run poorly and overheat.
• Cleaning the Chain Brake: Clean the chain brake mechanism regularly to ensure that it functions properly. A malfunctioning chain brake can be a serious safety hazard.
• Checking and Cleaning the Spark Plug: Check the spark plug regularly and clean or replace it as needed. A fouled spark plug can cause the engine to misfire.
• Lubricating the Bar and Chain: Use a high-quality bar and chain oil to lubricate the bar and chain. This will reduce friction and wear and tear. Check the oil level frequently and refill as needed.
• Sharpening the Chain Regularly: As mentioned earlier, a sharp chain is essential for efficient cutting. Sharpen your chain every time you refuel, or more often if you notice the chain is cutting slowly.
• Storing Your Chainsaw Properly: When not in use, store your chainsaw in a dry, safe place. Drain the fuel tank before storing the saw for extended periods.
• Following the Manufacturer’s Recommendations: Refer to your chainsaw’s owner’s manual for specific maintenance recommendations.
• Personal Anecdote: I once neglected to clean the air filter on my chainsaw, and the engine overheated and seized up. It cost me a lot of money to repair the damage. Since then, I’ve been meticulous about maintaining my chainsaw.

Safety First: Essential Precautions

Chainsaws are powerful tools that can be dangerous if not used properly. Always follow these safety precautions:

• Wear Appropriate Safety Gear: Always wear safety glasses, hearing protection, gloves, and chaps when operating a chainsaw. A helmet with a face shield is also recommended.
• Read the Owner’s Manual: Familiarize yourself with the chainsaw’s operating instructions and safety features.
• Inspect the Chainsaw Before Use: Before each use, inspect the chainsaw for any damage or loose parts. Make sure the chain is properly tensioned and sharpened.
• Start the Chainsaw on the Ground: Start the chainsaw on the ground, with the chain brake engaged.
• Maintain a Firm Grip: Hold the chainsaw firmly with both hands.
• Keep Your Feet Firmly Planted: Maintain a stable stance and keep your feet firmly planted on the ground.
• Be Aware of Kickback: Kickback is a sudden, uncontrolled movement of the chainsaw that can cause serious injury. Be aware of the causes of kickback and take steps to avoid it.
• Never Cut Above Shoulder Height: Cutting above shoulder height is dangerous and increases the risk of losing control of the chainsaw.
• Never Operate a Chainsaw When You Are Tired or Under the Influence of Drugs or Alcohol: Operating a chainsaw requires concentration and coordination. Do not use a chainsaw if you are impaired in any way.
• Keep Bystanders Away: Keep bystanders at least twice the height of the tree away from the cutting area.
• Statistics: According to the Consumer Product Safety Commission, chainsaws cause tens of thousands of injuries each year in the United States alone. Many of these injuries could be prevented by following basic safety precautions.
