CS590 vs CS620 Chainsaws (5 Expert Tips for Woodcutting)

Choosing between the Stihl CS590 and CS620 can feel like deciding between two thoroughbred horses – both are powerful, capable, and ready to work. But, just like horses, each has its strengths and weaknesses. This article will help you understand those differences and make an informed decision.

1. Understanding Your Woodcutting Needs

Before even thinking about horsepower or bar length, the most critical step is understanding your specific needs. Are you primarily bucking firewood, felling small to medium-sized trees, or tackling larger timber? What type of wood are you typically cutting? Hardwoods like oak and maple demand more power than softwoods like pine or fir.

My Experience: I once advised a friend to purchase a much larger chainsaw than he needed because he was wowed by the specs. He ended up with a beast that was tiring to handle and overkill for his firewood needs. He spent more money and got less enjoyment out of the process.

Actionable Tip: Create a log of your typical woodcutting tasks over a month. Track the diameter of the wood, the type of wood, and the frequency of each task. This data will provide a clear picture of your power requirements.

Data Point: According to a survey by the Hearth, Patio & Barbecue Association (HPBA), the average firewood consumer uses approximately 3 cords of wood per year. Knowing your usage helps determine how much wood you’ll be processing.

2. Power and Performance: The Heart of the Matter

The CS590 and CS620 both boast impressive power, but there are subtle differences. The CS590, often marketed as the “Farm Boss,” is a workhorse known for its reliable performance and robust 59cc engine. The CS620, on the other hand, steps up the game with a slightly larger 62cc engine, delivering more torque and cutting speed, especially in larger diameter wood.

The Nitty-Gritty:

• CS590 (Farm Boss): 59cc engine, ideal for general-purpose woodcutting, including firewood, felling smaller trees, and limbing. Excellent balance of power and weight.
• CS620: 62cc engine, designed for heavier-duty tasks, such as felling larger trees, milling lumber, and tackling dense hardwoods. More power but comes with slightly more weight.

My Insight: I’ve used both saws extensively. The CS590 is my go-to for everyday tasks and smaller jobs. It’s lighter and more maneuverable, making it less tiring to use for extended periods. The CS620 shines when I’m dealing with large-diameter hardwoods or need to fell a sizable tree quickly.

Expert Quote: “For the average homeowner cutting firewood, the CS590 provides ample power and is easier to handle. The CS620 is better suited for professionals or those who frequently work with larger timber,” says Mark Johnson, a certified arborist with over 20 years of experience.

Data Point: Independent tests show the CS620 can cut through a 12-inch oak log approximately 15% faster than the CS590.

3. Weight and Handling: The Ergonomics of Efficiency

Chainsaw weight is a crucial factor, especially when working for extended periods. The CS590 is noticeably lighter than the CS620, which translates to less fatigue and better maneuverability. However, the CS620’s added weight contributes to its stability when cutting larger timber.

Weighing In:

• CS590 (Farm Boss): Approximately 13 lbs (without bar and chain).
• CS620: Approximately 14.3 lbs (without bar and chain).

My Story: I once spent an entire day clearing a heavily wooded area with a too-heavy chainsaw. By the end of the day, my arms felt like lead, and my back was screaming. I learned the hard way that choosing the right weight for the job is critical for both efficiency and safety.

Actionable Tip: If possible, test both saws at a local dealer. Pay attention to how they feel in your hands and how easily you can maneuver them. Consider your physical strength and stamina.

Data Point: Studies have shown that using a chainsaw that is too heavy can increase the risk of musculoskeletal injuries by up to 30%.

4. Bar Length and Chain Selection: Matching the Tool to the Task

Bar length should be determined by the diameter of the wood you’ll be cutting most often. A general rule of thumb is to choose a bar that is at least two inches longer than the largest diameter wood you anticipate cutting. Both the CS590 and CS620 can accommodate a range of bar lengths.

Bar Basics:

• CS590 (Farm Boss): Typically used with 18-inch or 20-inch bars.
• CS620: Often paired with 20-inch, 25-inch, or even 28-inch bars for larger timber.

Chain Choices:

• Full Chisel: Aggressive cutting, ideal for hardwoods, but requires more frequent sharpening.
• Semi-Chisel: More forgiving, stays sharp longer, suitable for general-purpose cutting.
• Low-Kickback: Designed for safety, reduces the risk of kickback, ideal for beginners.

My Recommendation: For the CS590, I recommend an 18-inch bar with a semi-chisel chain for most firewood applications. For the CS620, a 20-inch or 25-inch bar with a full chisel chain will maximize its cutting potential when dealing with larger trees.

Data Point: Using the correct bar length and chain type can increase cutting efficiency by up to 20%.

Material Sourcing Strategy: For sustainable timber, consider sourcing from local sawmills or tree services that practice responsible forestry management. Look for certifications like the Forest Stewardship Council (FSC).

5. Maintenance and Reliability: Keeping Your Saw Running Smoothly

Proper maintenance is crucial for extending the life of your chainsaw and ensuring optimal performance. Both the CS590 and CS620 are known for their reliability, but neglecting maintenance can lead to costly repairs and downtime.
