Stihl Farm Boss Bar Size Guide: 5 Expert Tips for Safe Use

The Stihl Farm Boss is a workhorse, a reliable friend for tackling a wide array of wood-cutting tasks. But to truly unlock its potential and ensure your safety, you need the right bar size. It’s not a one-size-fits-all situation.

Understanding the Stihl Farm Boss

Before we get into the nitty-gritty of bar sizes, let’s quickly recap what makes the Stihl Farm Boss such a popular saw. It’s known for its power, durability, and ease of use. The Farm Boss typically comes with a 20-inch bar, making it versatile enough for felling small to medium-sized trees, limbing, and bucking firewood. However, that doesn’t mean a 20-inch bar is always the best choice.

Tip #1: Matching Bar Size to the Job

This is where many folks go wrong. They assume the bar that came with the saw is the only bar they can use, or they simply grab the longest bar they can find, thinking it will make them more efficient. Nope!

Smaller Jobs (Limbing, Small Firewood): For limbing branches or cutting small-diameter firewood (less than 10 inches), a shorter bar (16-18 inches) is ideal. It offers better control, maneuverability, and reduces the risk of kickback. I’ve used a 16″ bar on my Farm Boss for years when cleaning up storm damage – it’s like wielding a surgical instrument compared to a longer bar. You get more precise cuts, and you’re less likely to strain yourself.
Medium Jobs (Felling Small Trees, Medium Firewood): The standard 20-inch bar is a great all-around choice. It provides enough reach for felling small trees (up to 16 inches in diameter) and bucking medium-sized firewood. This is the sweet spot for versatility.
Larger Jobs (Felling Medium Trees, Large Firewood): If you’re consistently felling medium-sized trees (up to 24 inches) or dealing with large-diameter firewood, you might consider a longer bar (25 inches). However, be aware that a longer bar requires more power and can increase the risk of kickback if you’re not careful. I once tried using a 28″ bar on my Farm Boss to fell some larger oaks. While it technically worked, the saw was working hard, and my cuts weren’t as clean. I quickly realized that the saw was being pushed beyond its limits.

Data Point: According to a study by the Oregon State University Extension Service, using the correct bar length for the wood diameter can increase cutting efficiency by up to 20% and reduce operator fatigue by 15%.

Tip #2: Understanding Bar Terminology and Specifications

Let’s get familiar with some key terms:

Gauge: The width of the drive link that fits into the bar groove. The Farm Boss typically uses a .063″ gauge. Always match the gauge of the chain to the gauge of the bar.
Pitch: The distance between any three consecutive rivets on the chain, divided by two. The Farm Boss commonly uses a 3/8″ pitch chain. Again, always match the pitch of the chain to the pitch of the bar’s sprocket nose.
Drive Links: The number of links on the chain that fit into the bar groove. This is crucial for ensuring the chain is the correct length for the bar. You’ll find this number listed on the bar or in the chainsaw’s manual.

Actionable Tip: Before buying a new bar or chain, always check your Stihl Farm Boss’s manual. It will provide the correct gauge, pitch, and drive link count for your saw model.

Tip #3: Inspecting Your Bar Regularly

A damaged or worn bar can be a serious safety hazard. Regular inspection is key.

Check for Wear: Look for wear on the rails (the edges of the bar groove). If the rails are uneven or worn down, the chain won’t run smoothly, and you’ll experience more vibration and potential kickback.
Check for Damage: Inspect the bar for cracks, bends, or other damage. A damaged bar can break during use, causing serious injury.
Check for Burrs: Remove any burrs (small metal shavings) from the bar rails using a flat file. Burrs can damage the chain and increase friction.
Clean the Bar Groove: Use a bar groove cleaner (a small, hooked tool) to remove sawdust and debris from the bar groove. A clogged groove can prevent the chain from oiling properly, leading to premature wear.

Personal Story: I once ignored a small crack in my bar, thinking it was just a cosmetic issue. Big mistake! The crack eventually widened, and the bar broke while I was felling a small tree. Luckily, I wasn’t hurt, but it was a close call and a valuable lesson learned.

Tip #4: Proper Chain Maintenance is Key

Your bar and chain work together as a system. If your chain is dull or improperly sharpened, it will put extra stress on the bar, leading to premature wear and increased risk of kickback.

Sharpen Regularly: Sharpen your chain every time you refuel, or more often if you’re cutting dirty or abrasive wood. A sharp chain cuts smoothly and efficiently, reducing strain on the bar and engine.
Maintain Proper Depth Gauges: The depth gauges (the small tabs in front of each cutting tooth) control how much wood the chain takes with each pass. If the depth gauges are too high, the chain won’t cut effectively. If they’re too low, the chain will grab and cause kickback. Use a depth gauge tool to maintain the correct height.
Use the Right Chain Type: There are different types of chains for different applications. For example, low-kickback chains are designed to reduce the risk of kickback, while full-chisel chains are designed for faster cutting in clean wood. Choose the chain type that best suits your needs and experience level.

Expert Quote: “A sharp chain is a safe chain.” – Stihl Training Manual

Data Point: Studies have shown that using a properly sharpened chain can reduce cutting time by up to 30% and fuel consumption by 10%.

Tip #5: Mastering Safe Chainsaw Techniques

Even with the right bar size and a well-maintained chain, you can still get hurt if you don’t use proper chainsaw techniques.

Wear Proper Safety Gear: Always wear a helmet with a face shield, hearing protection, chainsaw chaps, gloves, and steel-toed boots.
Use a Firm Grip: Grip the chainsaw firmly with both hands. Keep your thumbs wrapped around the handles.
Maintain a Stable Stance: Stand with your feet shoulder-width apart and keep your weight balanced.
Be Aware of Kickback: Kickback occurs when the upper tip of the bar contacts a solid object or is pinched. It can cause the chainsaw to jump back towards you with tremendous force. Be aware of the kickback zone and avoid cutting with the upper tip of the bar.
Use the Correct Cutting Techniques: Learn and practice proper felling, limbing, and bucking techniques. There are many resources available online and in print.
Never Cut Above Shoulder Height: Cutting above shoulder height is dangerous and can lead to loss of control.
Take Breaks: Chainsawing is physically demanding. Take frequent breaks to avoid fatigue.

Case Study: A local logger I know, let’s call him Dave, got complacent after years of experience. He stopped wearing his chaps regularly, thinking he was too skilled to need them. One day, while limbing a tree, the chainsaw kicked back and struck his leg. Luckily, he only suffered a minor cut, but it was a wake-up call. He now wears his chaps religiously and encourages others to do the same. This highlights that experience doesn’t make you immune to accidents; it’s about consistent adherence to safety protocols.

Workflow Optimization for Wood Processing

Beyond just the bar size, let’s talk about optimizing your entire wood processing workflow for increased efficiency and reduced strain.

Log Handling Efficiency

Log Decking: Create a designated log decking area close to your work area. This minimizes the distance you need to carry logs.
Log Lifters/Cant Hooks: Invest in log lifters or cant hooks to make moving and positioning logs easier. These tools can save your back and prevent injuries.
Skidding Cones: When dragging logs out of the woods, use a skidding cone to protect the ends of the logs and prevent them from getting snagged on obstacles.
Mechanical Assistance: For larger operations, consider using a tractor or skid steer with a log grapple to move logs.

Data Point: Using a log lifter can reduce the amount of effort required to move a log by up to 50%.

Material Sourcing Strategies: Selecting Sustainable Timber

Harvesting Permits: Ensure you have the necessary permits and permissions before harvesting timber from any land.
Selective Harvesting: Practice selective harvesting, which involves removing only mature or diseased trees while leaving younger trees to grow. This helps maintain the health and biodiversity of the forest.
Sustainable Forestry Practices: Follow sustainable forestry practices, such as replanting trees after harvesting and minimizing soil erosion.
Local Sourcing: Source timber locally whenever possible. This reduces transportation costs and supports local economies.

Actionable Tip: Contact your local forestry service for information on sustainable harvesting practices and available resources.

Tool Usage Efficiency: Chainsaw Maintenance Routines

Daily Maintenance: At the end of each day, clean your chainsaw thoroughly, check the chain tension, and sharpen the chain if necessary.
Weekly Maintenance: Once a week, inspect the bar for wear and damage, clean the bar groove, and lubricate the sprocket nose.
Monthly Maintenance: Once a month, check the air filter and spark plug, and replace them if necessary.
Professional Servicing: Have your chainsaw professionally serviced at least once a year.

Personal Experience: I used to neglect my chainsaw maintenance, thinking it was a waste of time. But I quickly learned that a little bit of maintenance goes a long way. Since I started following a regular maintenance schedule, my chainsaw runs smoother, cuts faster, and lasts longer.

Project Planning and Execution in Wood Processing

Let’s delve into the strategic aspects of project planning and execution, drawing from my experience in wood processing and firewood preparation.

Planning Harvest Schedules

Seasonality: Consider the seasonality of your harvesting operations. Wood harvested in the winter typically has a lower moisture content, which can shorten drying times.
Weather Conditions: Monitor weather conditions and avoid harvesting during periods of heavy rain or snow.
Logistics: Plan your harvesting operations carefully to minimize transportation costs and environmental impact.

Data Point: Wood harvested in the winter can dry up to 25% faster than wood harvested in the summer.

Selecting Drying Methods

Air Drying: Air drying is the most common and cost-effective method for drying firewood. Stack the wood in a well-ventilated area and allow it to dry for 6-12 months.
Kiln Drying: Kiln drying is a faster but more expensive method. It involves drying the wood in a controlled environment using heat and air circulation.
Solar Drying: Solar drying is a more environmentally friendly alternative to kiln drying. It involves using the sun’s energy to heat and dry the wood.

Actionable Tip: When air drying firewood, stack the wood in rows with plenty of space between the rows to allow for good air circulation.

Measuring Log Dimensions Accurately

Diameter: Use a diameter tape to measure the diameter of the log at both ends.
Length: Use a measuring tape to measure the length of the log.
Volume: Calculate the volume of the log using a log scale.

Personal Anecdote: I once underestimated the volume of a load of logs and ended up running short of firewood in the middle of winter. Now, I always double-check my measurements to avoid similar situations.

Preparing Logs for Splitting

Bucking: Cut the logs into manageable lengths for splitting.
Debarking: Remove the bark from the logs. This can help speed up the drying process and prevent insect infestations.
Splitting: Split the logs into smaller pieces using a splitting axe or a log splitter.

Data Point: Using a log splitter can increase splitting efficiency by up to 500% compared to using a splitting axe.

Addressing Common Challenges in Wood Processing

Let’s tackle some common hurdles and their solutions.

Controlling Moisture Levels in Firewood

Moisture Meter: Use a moisture meter to check the moisture content of your firewood. The ideal moisture content for firewood is between 15% and 20%.
Proper Drying: Ensure that your firewood is properly dried before burning it. Burning wet firewood can produce creosote, which can build up in your chimney and create a fire hazard.
Storage: Store your firewood in a dry, well-ventilated area.

Expert Quote: “Burning dry firewood is essential for safety and efficiency.” – National Fire Protection Association

Dealing with Difficult Wood Types

Hardwoods: Hardwoods, such as oak and maple, are more difficult to split than softwoods, such as pine and fir. Use a log splitter or a heavy-duty splitting axe.
Knots: Knots can make wood difficult to split. Avoid splitting logs with large knots if possible.
Twisted Grain: Twisted grain can also make wood difficult to split. Use a hydraulic log splitter for these types of logs.

Personal Tip: For particularly stubborn logs, try using a splitting wedge and a sledgehammer.

Current Trends and Best Practices in Firewood Production

Seasoned Firewood: There’s a growing demand for seasoned firewood, which is firewood that has been properly dried and is ready to burn.
Bundled Firewood: Bundled firewood is becoming increasingly popular, especially for camping and outdoor activities.
Eco-Friendly Firewood: There’s a growing interest in eco-friendly firewood, such as firewood that has been harvested sustainably and dried using solar energy.

Actionable Tip: Consider offering seasoned or bundled firewood to your customers to increase your sales.
