Stihl MS 170 Bar Guide: Choosing the Best 18” Option (5 Pro Tips)

The Stihl MS 170 is a lightweight and versatile chainsaw, ideal for tasks like pruning, limbing, and cutting small trees. However, maximizing its potential requires selecting the right bar length. While the MS 170 typically comes with a shorter bar, an 18-inch bar can offer extended reach and cutting capacity. But is it the right choice for you? Let’s delve into the specifics.

Tip #1: Understanding the Trade-offs of an 18-Inch Bar

Before diving into the benefits, it’s essential to understand the trade-offs involved when equipping your Stihl MS 170 with an 18-inch bar.

Power vs. Length: The MS 170 is a relatively low-powered chainsaw. Increasing the bar length to 18 inches demands more from the engine. This can lead to:

• Slower Cutting Speed: The engine may struggle to maintain optimal chain speed, especially when cutting through dense hardwoods.
• Increased Wear and Tear: The added strain can shorten the lifespan of the engine and other components.
• Reduced Maneuverability: The longer bar makes the chainsaw less nimble, particularly in tight spaces.

Personal Experience: I recall trying to fell a moderately sized oak tree with a similar low-powered chainsaw equipped with an oversized bar. The saw bogged down frequently, and the job took significantly longer than expected. It was a clear demonstration that matching bar length to engine power is crucial.

Cost Factors: An 18-inch bar itself will cost more than shorter options. A decent Stihl 18-inch bar can range from $40 to $70, depending on the model and retailer. You might also need to factor in the cost of a new chain, as the existing chain might not be long enough. A new chain for an 18-inch bar can cost between $20 and $40.

Data Point: According to a survey conducted by the Outdoor Power Equipment Institute (OPEI), 65% of chainsaw users reported experiencing performance issues due to using an incorrectly sized bar. This highlights the importance of careful consideration.

Tip #2: Evaluating Your Cutting Needs

The most crucial factor in choosing the right bar length is understanding the type of cutting you’ll be doing.

Ideal Scenarios for an 18-Inch Bar:

• Felling Small Trees (Up to 14 Inches in Diameter): The 18-inch bar provides sufficient reach to fell trees with a trunk diameter of up to 14 inches, allowing for a clean cut without excessive maneuvering.
• Cutting Larger Firewood Rounds: If you regularly process larger diameter firewood rounds, the extra length can save you time and effort.
• Limbing Branches at a Distance: The extended reach can be beneficial for limbing branches that are difficult to access.

Scenarios Where a Shorter Bar Might Be Better:

• Pruning Small Branches: For pruning tasks, a shorter bar (14 or 16 inches) offers better control and maneuverability.
• Light-Duty Tasks: If you primarily use the chainsaw for light-duty tasks like cutting small pieces of wood or clearing brush, a shorter bar is more efficient.
• Working in Confined Spaces: A shorter bar is easier to handle in tight spaces, such as within dense shrubbery or around obstacles.

Cost Comparison: Using the wrong bar length can lead to inefficiencies. For example, if you’re using an 18-inch bar for tasks that could be easily handled with a 14-inch bar, you’re essentially wasting energy and increasing the wear and tear on your chainsaw. Over a year, this could translate to higher fuel consumption (an extra gallon or two of fuel, costing $10-$20) and potentially premature repairs (costing $50-$100).

Statistical Insight: A study by the Forest Resources Association found that using the appropriate bar length for the task at hand can increase cutting efficiency by up to 20%.

Tip #3: Considering Wood Type and Density

The type of wood you’ll be cutting significantly impacts the performance of the Stihl MS 170 with an 18-inch bar.

Hardwoods vs. Softwoods:

• Hardwoods (Oak, Maple, Hickory): Hardwoods are denser and require more power to cut through. The MS 170 may struggle to maintain optimal chain speed with an 18-inch bar when cutting hardwoods, especially if the wood is seasoned (dried).
• Softwoods (Pine, Fir, Spruce): Softwoods are less dense and easier to cut. The MS 170 can handle an 18-inch bar more effectively when cutting softwoods.

Moisture Content:

• Green Wood: Green wood (freshly cut) has a higher moisture content, making it easier to cut than seasoned wood.
• Seasoned Wood: Seasoned wood is drier and harder, requiring more power to cut.

Personal Anecdote: I once attempted to cut through a seasoned oak log with my MS 170 and an 18-inch bar. The chainsaw bogged down repeatedly, and I had to constantly adjust my cutting technique. It was a frustrating experience that highlighted the importance of matching the bar length to the wood type and moisture content.

Cost Implications: Struggling to cut through dense wood with an undersized chainsaw can lead to increased fuel consumption and wear on the chain. You might find yourself needing to sharpen the chain more frequently (costing $10-$15 per sharpening) or replacing it sooner than expected (costing $20-$40).

Data Analysis: According to data from the U.S. Forest Service, the average density of oak wood is around 45 pounds per cubic foot, while the average density of pine wood is around 30 pounds per cubic foot. This difference in density directly impacts the cutting performance of a chainsaw.

Tip #4: Optimizing Chain Selection and Maintenance

The right chain can make a significant difference in the performance of your Stihl MS 170, especially when using an 18-inch bar.

Chain Types:

• Low-Profile Chains: These chains are designed for safety and are less aggressive. They are suitable for beginners and light-duty tasks.
• Full-Chisel Chains: These chains are more aggressive and cut faster. However, they require more skill to use safely and are more prone to kickback.
• Semi-Chisel Chains: These chains offer a balance between cutting speed and safety. They are a good option for general-purpose use.

Chain Maintenance:

• Sharpening: Regularly sharpen your chain to maintain optimal cutting performance. A dull chain puts more strain on the engine and can lead to kickback. I typically sharpen my chains after every two to three tanks of fuel.
• Lubrication: Ensure the chain is properly lubricated to reduce friction and wear. Use a high-quality bar and chain oil. I prefer using a vegetable-based oil, as it’s more environmentally friendly.
• Tensioning: Maintain proper chain tension to prevent the chain from derailing or binding.

Cost Savings: Proper chain maintenance can significantly extend the life of your chain and reduce the need for frequent replacements. Sharpening your own chain with a file and guide can save you money compared to taking it to a professional. A decent chainsaw file and guide can cost around $20-$30.

Industry Standard: Most chainsaw manufacturers recommend sharpening the chain after every two to three hours of use.

Tip #5: Mastering Cutting Techniques

Even with the right bar and chain, proper cutting techniques are essential for maximizing the performance of your Stihl MS 170 and ensuring your safety.

Safe Cutting Practices:

• Wear Appropriate Safety Gear: Always wear safety glasses, hearing protection, gloves, and chaps when operating a chainsaw.
• Maintain a Stable Stance: Keep your feet firmly planted and maintain a balanced stance.
• Use Proper Grip: Grip the chainsaw firmly with both hands.
• Be Aware of Kickback: Understand the causes of kickback and take precautions to avoid it.

Cutting Techniques for an 18-Inch Bar:

• Felling: When felling trees, use the bore cut technique to control the direction of the fall.
• Limbing: When limbing, work from the base of the tree towards the top, cutting on the underside of the branches to avoid pinching the bar.
• Bucking: When bucking logs, use a sawhorse to support the log and avoid cutting into the ground.

Experience Sharing: I once witnessed a fellow woodcutter who neglected to wear safety glasses while limbing a tree. A small piece of wood flew into his eye, causing a painful injury. This incident reinforced the importance of always wearing appropriate safety gear.

Cost Efficiency: Mastering proper cutting techniques can save you time and effort, and reduce the risk of accidents. Accidents can lead to costly medical bills and damage to your equipment. Investing in a chainsaw safety course (typically costing $50-$100) can be a worthwhile investment.

Actionable Takeaways and Next Steps:

• Evaluate Your Needs: Determine the type of cutting you’ll be doing most often.
• Consider Wood Type: Factor in the type of wood you’ll be cutting and its moisture content.
• Choose the Right Chain: Select a chain that is appropriate for your skill level and the type of cutting you’ll be doing.
