The roar of a chainsaw cutting through hardwood, the satisfying spray of sawdust, and the weight of a powerful tool in your hands"”there's something primal about wielding a 20-inch chainsaw that makes you feel like you can conquer any tree, any storm damage, any backyard wilderness.
Whether you're clearing fallen timber after a storm, managing a wooded property, or cutting next winter's firewood supply, the right 20-inch chainsaw transforms hours of backbreaking labor into efficient, purposeful work that gets the job done.
Why Choose a 20-Inch Chainsaw?
A 20-inch chainsaw represents the sweet spot for serious property owners and semi-professional users. While smaller 14-16 inch models handle light pruning and limbing tasks, and massive 24-inch professional saws tackle commercial logging operations, the 20-inch chainsaw delivers versatile cutting power for real-world property management.
With a 20-inch bar, you can fell trees up to 36-38 inches in diameter (by cutting from both sides), buck large logs efficiently, and still maintain enough maneuverability for detailed work. These saws typically feature engines ranging from 50cc to 60cc for gas models, or equivalent power in modern battery-powered versions, providing the muscle needed for sustained cutting without the excessive weight of larger professional models.

Safety Features That Matter
Modern chainsaws incorporate multiple safety systems:
Inertia Chain Brake: Automatically stops the chain during kickback events. Look for models with both manual and inertia activation.
Anti-Vibration Systems: Reduce operator fatigue and improve control. Premium models feature spring-mounted handles that isolate vibration.
Throttle Lockout: Prevents accidental acceleration. Two-step activation ensures intentional operation.
Chain Catcher: Prevents broken chains from whipping back toward the operator.
Kickback Protection: Low-kickback chains and reduced kickback bars minimize rotational forces.
Maintenance for Peak Performance
Daily Care Routine
- Clean the air filter - A clogged filter reduces power and increases fuel consumption
- Check chain tension - Proper tension prevents premature wear and improves cutting efficiency
- Inspect the chain brake - Test function before each use
- Fill bar oil reservoir - Automatic oilers only work with adequate oil supply
- Examine chain sharpness - Sharp chains cut faster with less effort
Weekly Maintenance Tasks
- Remove and clean the spark plug
- Flip the guide bar to ensure even wear
- Clean the bar groove and oil holes
- Inspect the sprocket for wear
- Check all nuts and bolts for tightness
Seasonal Service Points
Spring: Replace air filter, spark plug, and fuel filter. Inspect starter rope condition.
Summer: Monitor bar oil consumption in hot weather. Clean cooling fins more frequently.
Fall: Prepare for heavy use with fresh fuel mix and backup chains.
Winter: Use winter-grade bar oil. Store with fresh fuel or run dry for extended storage.
Professional Operating Techniques
Proper Stance and Grip
Maintain a stable, balanced stance with feet shoulder-width apart. Keep your left thumb wrapped under the front handle"”this "thumb wrap" position helps maintain control during kickback. Lock your left elbow to prevent the saw from rotating toward your body.
Cutting Methods
Felling Cuts: Use the open-face notch technique for better directional control. Cut the notch to 70-80% of trunk diameter.
Bucking: Support logs to prevent binding. Cut 1/3 from bottom, then complete from top to prevent pinching.
Limbing: Work from base to top, keeping the guide bar on opposite side of trunk from your body.
Kickback Prevention
- Never cut with the upper nose quadrant of the bar
- Maintain sharp chains"”dull chains increase kickback risk
- Stand to the side, not directly behind the saw
- Keep both hands firmly on handles at all times
- Don't cut above shoulder height
Buying Considerations
Budget Ranges
Entry Level ($300-500): Basic features, suitable for occasional use. Examples include Poulan Pro and smaller Husqvarna models.
Mid-Range ($500-800): Professional features with homeowner pricing. Echo, Husqvarna Rancher series, and Stihl Farm Boss models.
Premium ($800+): Professional-grade construction and performance. Stihl MS 362, Husqvarna 562XP, and high-end battery models.
Where to Buy
Authorized Dealers: Best for warranty support and professional setup. Access to OEM parts and factory-trained service.
Online Retailers: Competitive pricing but limited support. Verify authorized dealer status for warranty coverage.
Big Box Stores: Convenient but often carry consumer-grade models only. Limited expertise and service options.
Environmental Considerations
Emissions Standards
Modern chainsaws must meet strict EPA and CARB emissions standards. Look for models with:
- Stratified scavenging technology
- Catalytic mufflers
- X-Torq or similar low-emission engines
Noise Levels
Gas models: 100-115 dB - Hearing protection mandatory Battery models: 85-95 dB - Significantly quieter operation
Sustainable Practices
- Use biodegradable bar oil when possible
- Properly dispose of used oil and filters
- Consider battery models for reduced environmental impact
- Maintain equipment for maximum efficiency and longevity
Expert Tips for Maximum Performance
- Break-in Period: New chains stretch significantly. Re-tension frequently during first few uses.
- Fuel Quality: Use fresh fuel with quality 2-stroke oil. Ethanol-free fuel prevents carburetor issues.
- Winter Operation: Pre-warm the saw indoors. Use winter-grade bar oil to maintain flow.
- Chain Selection: Match chain aggressiveness to wood type. Semi-chisel for dirty wood, full chisel for clean cuts.
- Storage Prep: Run saw dry or use fuel stabilizer. Store in dry location with bar cover installed.
Common Mistakes to Avoid
- Over-tightening chains causes premature bar and sprocket wear
- Using motor oil instead of bar oil leads to inadequate lubrication
- Forcing dull chains increases wear, fuel consumption, and accident risk
- Improper fuel mixture causes engine damage and poor performance
- Neglecting air filter maintenance reduces power and engine life
