If you’re choosing between a Greenworks 40V chainsaw and a gas saw, consider the Greenworks for lighter, occasional jobs and convenient battery operation; consider gas for sustained or demanding cutting, but compare the exact models because performance varies. One Greenworks 40V review reports slower cutting than a gas saw, while Greenworks says its battery-powered saws cut quicker than a 40cc gas equivalent, so those broad comparisons don’t settle how two specific saws will perform. [1][2] For more detail, see . How to Maintain a Greenworks 40V Chainsaw.
For example, if you mostly trim branches or cut a few pieces of firewood now and then, a battery saw may suit your routine. If you expect long cutting sessions or demanding work, compare gas models as well—but don’t assume every gas saw outperforms every battery saw. The sources offer conflicting general comparisons, and the Greenworks statement covers battery-powered chainsaws rather than establishing a result for every 40V model. [1][2]
Before choosing, compare the specific saws’ bar sizes, batteries, and the work you plan to do. A bar that suits occasional branch trimming may not be the right fit for larger logs, and battery operation may be convenient for one work pattern but less suitable for another; check the specifications and consider how long and where you’ll be cutting. The sources do not provide enough detail to name a universally better saw or to make a model-by-model performance comparison. [1][2]
Key takeaways
Consider the Greenworks 40V for lighter, intermittent work and battery convenience.
Consider gas for sustained or demanding cutting, while checking the specific model.
Compare bar size, battery, and intended work—not power source alone.
How do the Greenworks 40V and gas saws compare?
For light, occasional cutting, a Greenworks 40V chainsaw may suit you; for heavier or sustained work, compare the exact gas and battery models rather than assuming one type always cuts faster. The available observations are mixed: one review describes the 40V saw as slower and less powerful than a gas saw, while another reports a slight speed edge for a Greenworks saw in its test.[2][3] You may also find this useful: .

Criterion | Greenworks 40V chainsaw | Gas chainsaw |
|---|---|---|
Power source | Runs on a rechargeable battery; check which battery the specific model requires and whether one is included. | Runs on gasoline; confirm the model’s fuel requirements in its manual. |
Recharging or refueling | Plan around charging and having a charged battery available. The supplied sources do not give a dependable run-time comparison, so do not assume one charge will cover a particular job. | Plan to refuel as needed. The supplied sources do not provide a fuel-use or refueling comparison. |
Likely workload fit | Consider it for occasional jobs such as trimming branches or cutting a modest stack of firewood, provided the model’s capacity suits the wood and task. Reviews disagree on cutting performance, so treat workload fit as model- and task-dependent.[2][3] | Consider it when you are comparing options for more demanding work, but do not assume every gas saw will outperform every battery saw. One Greenworks source claims its battery saws deliver more torque and faster cutting than a 40cc gas equivalent; independent review observations differ.[1][2][3] |
Performance evidence | One reviewer reported slower cutting and less power than a gas saw; another found a Greenworks saw cut slightly faster in a test.[2][3] | The supplied reviews do not establish a universal gas-saw performance advantage.[2][3] |
Model and kit check | Confirm the exact model specifications, bar and chain details, and whether the battery and charger are included. | Confirm the exact model specifications and what comes with the saw. |
In practice, choose by the work you expect to do and the exact saws you are comparing, not by power source alone. For example, if you mainly trim branches around the yard, a 40V model may be worth considering; if you expect repeated, demanding cuts, compare its documented capacity and test results with a specific gas model. The cited material does not provide run times, charging durations, fuel costs, or enough consistent testing to promise a winner for every workload.
How much cutting power do you need?
Choose a Greenworks 40V chainsaw for the work you actually expect it to do, rather than assuming it will always cut faster—or slower—than a gas saw. The available accounts give different results, and they do not establish performance for every Greenworks 40V model or cutting condition.
Greenworks says its battery-powered chainsaws deliver 20% more torque and quicker, more efficient cutting than a 40cc gas chainsaw equivalent.[1] Treat that as the manufacturer’s claim, not a guarantee for every cut. Your results can depend on the particular saw, the wood, and the condition of the chain; the sources here do not compare every model or cutting setup.
Reviews also point in different directions. One test reported that a Greenworks G-MAX saw cut slightly faster than the gas saw it was compared with, though the reviewer suggested that the difference may have had another explanation.[3] Another Greenworks 40V review described the saw as less powerful and slower-cutting than a gas saw.[2] Those accounts concern particular reviews and tests, not a universal result.
For example, if you mainly cut smaller branches or make occasional cuts around your property, consider whether the 40V saw’s tested performance fits that workload. If you regularly tackle larger or tougher wood, do not choose based on Greenworks’ percentage claim alone: look for a comparison involving the specific model and cutting task you have in mind. The evidence provided does not give a reliable wood-size limit or a single cutting-speed result that applies to all users.
A practical takeaway is to compare like with like: the exact saw models, similar wood, and similar chain condition. Read the test setup as well as the conclusion, and treat a small speed difference as specific to that test. If you cannot find a close comparison, base your choice on the jobs you expect to do and avoid assuming that either battery or gas will win every cut.
When does battery convenience matter most?
Battery convenience matters most when your cutting is occasional and you value avoiding some of the hassles noted in a review of the Greenworks 40V saw, rather than working through a long session of repeated cuts. [2] If you’re trimming a few fallen branches after a storm or cutting a small pile of limbs for yard cleanup, consider how often you’ll use the saw and how much cutting you expect to do at one time. For extended work, compare that plan with the review’s notes about slower cutting than a gas saw and the saw’s auto-off behavior. [2]
Match the battery setup to your work
Before buying, check the exact battery capacity, whether a battery is included, your charging setup, and whether you can get a spare. Those details help you plan for the job, but the available source does not provide consistent runtime figures for comparing the Greenworks 40V saw with a gas saw. [2] So don’t count on a specific number of cuts or hours per charge; instead, think through the pieces you need to cut and whether you can pause to recharge or swap batteries.
For example, if you expect to make a few cuts and then put the saw away, a battery workflow may fit better than preparing for a long cutting session. If you regularly have a large stack of logs to process, consider the review’s report that the Greenworks saw cuts more slowly than a gas saw. [2] That is a practical limitation to weigh, not a promise about how quickly either saw will handle your particular wood.
Try the controls you’ll use
Convenience also depends on whether the saw is comfortable to start and manage with your usual work gloves. The review says the Greenworks saw can be hard to turn on with gloves on. [2] If you can, handle the saw before buying and check whether you can reach and operate its controls while wearing the gloves you plan to use.
Use the same checklist for either option: how often you cut, how long each session lasts, whether you can charge between tasks, and whether a spare battery is available. The review flags battery availability as a concern, so verify that you can obtain the battery setup you need before relying on it for a job. [2] Choose based on your actual workload and setup, and treat runtime as something to confirm for the specific battery and conditions rather than assume.
When is a gas saw the more practical choice?
A gas saw is more practical when you expect long stretches of cutting and would rather refuel than pause to recharge, but compare the exact models before deciding. The available comparisons do not support a blanket claim that every gas saw outperforms every battery saw: one source says Greenworks battery saws cut more efficiently than a 40cc gas equivalent, while another review reports a Greenworks 40V saw cutting slightly faster than the saw it tested.[1][3]
When refueling fits your work
Think about the job, not just the power source. If you are cutting for an extended stretch and have fuel available, a gas model may fit your workflow better than stopping to wait for a battery to charge. If your cutting comes in short sessions, that advantage may matter less; the right choice depends on how the specific saws perform and how you plan to use them.
For example, if you expect to cut a steady pile of logs in one session, compare the gas model’s stated runtime and refueling process with the battery model’s runtime and charging needs. The sources here do not provide those specifications for a particular gas saw, so check the manuals and product details for the models you are considering rather than assuming that gas automatically means more cutting capacity.
Compare like with like
Use the same kind of task when comparing saws: similar wood, similar cuts, and the same chain condition where possible. One review describes a Greenworks 40V saw as cutting slightly faster than the saw in its test, while a separate comparison makes a claim about Greenworks battery saws and a 40cc gas equivalent.[1][3] Those results point in different directions, so they are not a sound basis for declaring one power type the winner across the board.
Check which exact Greenworks 40V model and gas model you mean, then look for comparable test conditions and specifications. A review of one saw does not establish how every gas model will perform against every battery model.
Include upkeep and handling
Before choosing, read the manuals for both models and account for their stated upkeep and handling requirements. The available sources do not describe those requirements in enough detail to compare them, so do not assume a specific maintenance routine or handling difference without checking the manuals.
Also consider how the saw feels to operate with the gloves you plan to wear. A review of one Greenworks 40V model lists difficulty turning it on with gloves among its drawbacks, but that observation applies to that review, not to every Greenworks saw or every gas saw.[2] Try the controls if you can, and use the manual’s operating guidance to make the final call.
What should you choose for your usual jobs?
For occasional yard cleanup, choose between battery convenience and the exact battery-and-charger package; for frequent or demanding cuts, compare the specific saws rather than relying on “battery” or “gas” labels. The right choice depends on the jobs you actually do, such as trimming fallen branches after a storm or making repeated cuts through larger material.
Occasional cleanup
If you expect to make a few cuts and put the saw away, check what comes with the particular Greenworks 40V model you’re considering. Confirm whether its listing includes a battery and charger, and make sure the package fits your needs; the section’s sources do not establish what is included with every model.
Also consider how the saw feels when you hold it and reach for its controls. A review of a Greenworks 40V saw reported that it was hard to turn on while wearing gloves [2]. If you usually work with gloves, try the controls before buying if you can, or look closely at how you would operate them with your gloves on.
Frequent or demanding cuts
For regular cutting or tougher jobs, look for comparisons that test the exact models you might buy. In one comparison, the Greenworks G-MAX saw and the other saw began cutting at the same time, and the Greenworks cut the test material slightly faster [3]. That result is specific to the saws and material in that review, so it should not be treated as proof that every Greenworks 40V chainsaw will cut faster than every gas chainsaw.
A separate Greenworks 40V review described the saw as less powerful and slower-cutting than a gas saw [2]. Read these findings together: test conditions and model details matter, and a broad power-source label cannot tell you how a particular saw will perform. When you compare options, look for results involving the same kind of cutting you expect to do, rather than choosing on battery or gas alone.
A practical way to decide
Write down your usual tasks: occasional branch cleanup, repeated firewood cuts, or another specific job. Then compare the exact models’ available test results and package details, and check the controls with gloves if possible. If your work is mostly occasional cleanup, prioritize a package and controls that suit you; if you cut often or face demanding material, give tested performance for those exact models more weight.
Make the choice based on your workload
Choose the saw that fits the cuts you actually make and how you work: a Greenworks 40V may suit you if its exact model specifications and battery setup match your needs, while a gas saw may be the better fit for your workload and preferences.
Don’t decide from the power source alone. A Greenworks review describes a 40V model as less powerful and slower-cutting than a gas saw, while another comparison reports a Greenworks saw cutting slightly faster in its test; those differing results are a reason to compare the specific models and conditions, not to assume one type always wins. [2][3]
Check the match before you buy
Start with the cuts you expect to make. If you mainly plan occasional trimming or cutting manageable pieces, check whether the Greenworks model’s stated capabilities and included battery package suit that work. If you expect repeated, sustained cutting, compare the particular gas saw’s specifications and operating requirements with the way you plan to use it; the available sources do not establish that every gas saw will outperform every 40V model.
Then verify what comes in the package. Confirm the exact saw model, whether a battery is included, and the manufacturer’s instructions for operation and care. These details can change what you need to purchase and how the saw fits your routine, so don’t rely on a general “40V” label or a review of a different configuration.
The takeaway is simple: choose by model, workload, and operating preference, not by battery versus gas as a blanket rule. Before you buy, compare the exact product specifications and package contents, then read the manufacturer’s instructions to make sure the saw suits your planned cuts.
