Choosing the Right 20 in Chainsaw: Key Factors to Consider
Bar Length and Intended Workload
A 20 inch bar increases reach and lets you cut larger-diameter trunks and longer sections in a single pass. That capability matters if you routinely fell medium to large trees or need to process storm-downed timber quickly.
Longer bars also increase torque demand on the engine or motor and make the saw heavier to handle. If you mostly prune small branches, a 20 inch bar is overkill; for cutting thick rounds and crosscutting big limbs a 20 inch bar provides real efficiency gains, but expect more weight and a learning curve for safe handling.
Engine or Motor Performance
For gas chainsaws look at displacement, torque characteristics, and how the saw holds chain speed under load. For battery models consider peak motor torque and sustained output as well as how power drops off as the battery discharges.
High sustained RPM and consistent torque reduce the tendency to stall in dense wood and shorten cut times. However, greater power often means higher fuel consumption or faster battery drain, so balance peak performance with run time needs for your typical jobs.
Weight and Ergonomics
Weight affects fatigue and control. A 20 inch chainsaw will be heavier than shorter-bar models, so handle balance, grip shape, and anti-vibration systems become more important. Proper balance makes long cuts and overhead or awkward-angle work safer and less tiring.
Ergonomics also dictate how manageable the saw is during limbing and bucking. Features like a comfortable rear handle, wraparound front handle, and well-placed controls reduce the risk of slips or accidental throttle inputs during demanding jobs.
Chain Tensioning and Maintenance Access
Frequent maintenance is part of owning a longer-bar saw because larger cuts dull chains faster. Easy, tool-free chain tensioning and simple bar removal speed up on-site maintenance and reduce downtime.
Accessible air filters, straightforward spark plug access for gas models, or easily replaceable battery packs for cordless saws keep the saw working through a long day. Consider how straightforward replacement chains, bars, and guide sprockets are to source in your area.
Safety Systems and User Controls
A 20 inch chainsaw delivers more momentum during a kickback event, so robust safety features are essential. Look for an effective chain brake, low-kickback chain options, and good throttle interlock controls that prevent accidental acceleration.
Anti-vibration mounts help reduce hand fatigue, which in turn lowers the chance of mishandling. Clear, reachable kill switches and an intuitive choke or start system also reduce fumbling during hot starts or in emergency stops.
Serviceability and Parts Availability
A heavy-use 20 inch chainsaw will eventually need replacement chains, bars, sprockets, or professional servicing. Ease of finding compatible replacement parts and filters locally or from common suppliers affects long-term ownership costs and downtime.
Consider how simple it is to obtain replacement chains with the correct pitch and gauge, whether bars are standardized, and whether common repair parts are documented. Readily available parts and straightforward service procedures keep a saw in service through years of heavy cutting.
When a 20 Inch Bar Is the Right Choice
A 20 inch chainsaw fits gardeners and landowners who regularly cut trunks, large limbs, or need to clear storm damage quickly. It reduces the number of passes required on big logs and helps you complete crosscuts and limbing with fewer repositionings.
If your property has many specimen trees, thick hedgerow trunks, or you split rounds for firewood, the reach and bite of a 20 inch bar are practical advantages. For occasional small pruning tasks the extra weight and maintenance make shorter bars a better match.
- Best for felling medium to large trees and crosscutting big logs
- Saves time on long cuts but increases saw weight and torque needs
- Requires more attention to safety and maintenance
Gas Vs Battery Considerations for 20 Inch Saws
Gas-powered 20 inch chainsaws typically deliver the highest continuous power and longer runtime between refuels, which is useful on long days or remote properties. They require regular fuel management, spark plug and carburetor care, and more frequent initial maintenance.
Cordless battery 20 inch units are easier to start and maintain and produce less vibration and noise, but runtime and sustained torque depend on battery capacity and motor efficiency. If you choose cordless, factor in spare battery packs and charging strategy.
- Gas: strong continuous power, higher maintenance
- Battery: cleaner operation, limited continuous runtime
- Match power source to job duration and remote access needs
Routine Maintenance That Keeps a 20 Inch Saw Reliable
Regular chain sharpening, checking tension, and inspecting the bar rails extend cutting performance and reduce stress on the drive sprocket. Clean or replace air filters and inspect the clutch drum and sprocket for wear to avoid sudden failures during heavy use.
Lubrication is critical on longer bars. Ensure the oil pump functions and use the correct bar oil grade. For battery saws, monitor battery health and storage procedures to preserve runtime.
- Sharpen chain frequently when cutting abrasive or dirty wood
- Check bar rails for burrs and clean oil ports
- Follow recommended battery storage and charging cycles
Handling Techniques for Safer Long-Bar Cuts
Use a firm two-handed grip with both thumbs wrapped where possible and stand to the side of the cutting path. When crosscutting, let the saw reach full chain speed before engaging the wood and avoid forcing the bar through the cut.
Plan cuts to reduce bind and use wedges if needed to prevent pinching. For felling, follow standard notch-and-back-cut procedures and watch for hidden tension in limbs that can spring once cut. Take frequent rest breaks to maintain control and reduce fatigue.
- Maintain full chain speed before starting the cut
- Use wedges or back cuts to avoid binding
- Position feet and body out of the line of fall
Transporting and Storing a 20 Inch Chainsaw
Secure the saw with a bar cover and make sure the chain is depressed or immobilized before transport. For gas models drain or secure fuel in accordance with local guidelines when storing for long periods.
Store the saw in a dry, ventilated place and periodically treat the bar with a light coat of oil to prevent rust. Remove batteries for long-term storage and keep them partially charged according to manufacturer guidance.
- Use a rigid bar cover during transport
- Store in a dry place away from direct moisture
- Remove battery packs for extended storage
How We Chose the Best 20 in Chainsaw
We focused on attributes that directly affect real-world use of a 20 inch chainsaw on yards, homesteads, and small woodland properties. Selection began with models designed for heavy-duty cutting and long bars; any lightweight or strictly ornamental saws were excluded because they do not meet the workload implied by a 20 inch bar. We prioritized mechanical durability, measured as bar-and-chain longevity, sprocket and clutch robustness, and chassis materials that withstand sustained cuts. Cutting performance was assessed via engine or motor torque, chain speed under load, and how well a saw slices through large-diameter softwood and hardwood. Maintenance and serviceability were also key: easy chain tensioning, accessible air filters, and straightforward spark plug or battery access were required. Safety features such as effective chain brakes, anti-vibration systems, and reliable throttle locks influenced selection. Fuel efficiency or battery run time and the availability of replacement parts completed the editorial filters. We excluded any saws lacking clear specifications for bar compatibility or with limited parts support.
FAQ
Is a 20 inch chainsaw too big for home yard work?
It depends on the tasks you do. A 20 inch bar is ideal for large trunks and frequent heavy cutting, but it adds weight and requires more maintenance. For light pruning and small trees, shorter bars are easier to handle.
How often should I sharpen a chain on a 20 inch bar?
Sharpening frequency depends on wood type and abrasiveness, but expect to touch up the chain after every few hours of hard cutting. Inspect cutting performance and sharpen whenever the saw pulls or burns the wood.
Can battery-powered 20 inch chainsaws match gas models for felling?
Battery 20 inch saws can handle many felling tasks, especially with high-capacity packs, but sustained heavy cuts on dense hardwood are still an advantage for high-displacement gas engines. Battery systems excel in cleaner, quieter operation.
What safety gear is essential when using a 20 inch chainsaw?
