Best Heavy-Duty Chainsaws for Cutting Down Trees

The best chainsaws for cutting down trees at home are the Husqvarna 455 Rancher for most 12 to 18 inch trees, the Echo CS-590 Timber Wolf when you want maximum cutting speed and bar-length flexibility, and the Husqvarna 460 Rancher with a 24-inch bar for trunks above roughly 20 inches. If your trees are under 12 inches across, the Husqvarna 450 Rancher or Stihl MS 271 is the more sensible, lighter choice.

Felling is the most dangerous job you can do with a saw, so this guide spends as much time on bar length, protective gear and cutting technique as on engine size. Picking a saw by bar length alone is the most common mistake: a 20-inch bar on an underpowered 40cc engine bogs down in hardwood, while a 60cc saw with a 24-inch bar is more than a homeowner needs for a handful of pines. The sections below match engine displacement, bar length and trunk diameter, then rank eight current gas models.

Quick picks by tree diameter

• Trees up to 12 inches: Husqvarna 450 Rancher or Stihl MS 271 with an 18 or 20-inch bar.
• Trees 12 to 18 inches: Husqvarna 455 Rancher, Stihl MS 291 or Echo CS-590 with a 20-inch bar.
• Trees 18 to 24 inches: Husqvarna 460 Rancher (24-inch bar) or Echo CS-590 fitted with a 24-inch bar.
• Trees above 24 inches: hire a certified arborist. A homeowner saw is the wrong tool for this size, and the consequences of a mistake rise sharply.

How we chose

This guide is based on manufacturer specifications, published professional and consumer roundups, and the cutting requirements that arborist and forestry training programs describe for felling. We did not run our own cutting trials, and we do not claim personal use of any saw. A saw made the list if it met these criteria:

• Engine size of about 45cc or more. Below that, 18 to 20-inch bars cut slowly in hardwood and encourage forcing the saw, which raises kickback and pinch risk.
• Bar length of 18 inches or more as shipped or available. Felling needs a bar that exceeds the trunk diameter or lets you cut from both sides.
• An inertia-activated chain brake and an anti-vibration system. These are baseline safety and fatigue features on any saw you plan to run for an hour of felling and bucking.
• Weight that a non-professional can hold in a cut. The powerhead weight matters because tired arms lose control of a saw.
• Current availability in 2026 and a reachable service network. A saw you cannot get serviced or sharpen parts for becomes a poor long-term buy.

Weights below vary by source because some publish the powerhead alone and others the complete saw with bar and chain. Treat them as ranges and compare the same basis when you shop.

Match bar length to tree diameter: a worked example

A saw cuts a trunk in one pass only when the usable bar length is longer than the trunk. Usable length is shorter than the printed bar length because the first couple of inches sit inside the saw body and bar mount. A practical rule is usable length equals bar length minus about 2 inches.

1. Measure the trunk. Wrap a tape around the trunk at chest height and divide the circumference by 3.14. A 50-inch circumference gives a diameter of about 16 inches.
2. Add a working margin. You want the bar to clear the far side by a couple of inches so the tip is not buried in the last bit of wood, which is where kickback risk climbs. 16 inches plus 2 inches of margin is 18 inches of usable length.
3. Convert to a printed bar length. 18 inches usable plus 2 inches inside the saw body is a 20-inch bar. A 20-inch bar is the right answer for a 16-inch tree.
4. Check engine power. A 20-inch bar wants about 50cc as a minimum and 55cc or more for dense hardwood such as oak or hickory. The 455 Rancher, MS 291 and CS-590 meet that; the Prorun PCS218 does not.
5. Plan for the bigger tree. If the largest tree on your list is 22 inches, working from both sides with a 20-inch bar is possible but technical and slow. A 24-inch bar on a 60cc saw is the better tool and cheaper than a mistake.

The same logic gives a short fit matrix: 14-inch tree needs an 18-inch bar, 16-inch tree needs 20, 20-inch tree needs 24, and anything bigger is a professional job.

Best chainsaws for cutting down trees

1. Husqvarna 455 Rancher: best all-round felling saw

Specs: 55.5cc · about 3.5 hp · 20-inch bar · 13.2 lb powerhead · X-Torq engine · inertia chain brake · side-access chain tensioning

The 455 Rancher sits in the sweet spot for properties with mixed trees: enough displacement to pull a 20-inch bar through hardwood, light enough to hold through a dozen bucking cuts. It carries Husqvarna’s X-Torq low-emission engine, which is designed to deliver the torque of a bigger engine with reduced fuel use, and it has Smart Start and side chain tensioning that make routine adjustments quick.

Best for: homeowners with oak, maple, or pine in the 12 to 18 inch range.

Skip if: your largest trees exceed 20 inches; step up to the 460 Rancher.

Pros: strong power for its weight, widely serviced, reliable starting. Cons: costs more than the 450 Rancher for a modest bump in power; bar-length options are narrower than on the Echo.

2. Echo CS-590 Timber Wolf: fastest cutting and flexible bar options

Specs: 59.8cc · about 4 hp · 18, 20 or 24-inch bar compatible · about 16 lb complete · professional-grade engine · inertia chain brake

The Timber Wolf has the largest engine in its price class and takes a range of bar lengths, so one powerhead can serve small and large trees. Third-party reviewer comparisons report it among the quickest gas saws through a standard log, a benefit when you are trying to finish a felling cut cleanly and step away. It is heavier than the Rancher 450 or 455, and the added weight is noticeable on long bucking sessions.

Best for: owners who want one saw for firewood and felling, with the option of going to a 24-inch bar later.

Skip if: you only cut small branches and limbs; the weight is wasted.

Pros: high power, bar flexibility, strong value for the engine size. Cons: heavy, louder than smaller saws, requires the usual two-stroke fuel and maintenance discipline.

3. Husqvarna 460 Rancher: best for big trunks

Specs: 60.3cc · 24-inch bar · about 16.5 lb · centrifugal air pre-filtration · LowVib vibration reduction · inertia chain brake

This is the saw for trees from roughly 18 to 24 inches. The 24-inch bar means you can often finish a felling cut in a single pass, and the air pre-filtration system keeps sawdust out of the filter, which matters when you are making deep cuts. The LowVib system reduces handle vibration, which is useful on long days. The extra length also means more leverage on your arms, so wear the full gear listed below and do not use this saw above chest height.

Best for: large hardwoods and storm-damaged trunks on a rural property.

Skip if: you mostly cut under 14 inches; a smaller saw is easier and safer.

Pros: long bar, strong engine, effective filtration. Cons: heavy and long, more costly than the 450 and 455.

4. Husqvarna 450 Rancher: best lighter saw for small to medium trees

Specs: 50.2cc · 20-inch bar · about 13.5 lb · ergonomic handle · automatic chain oiler · spring-assisted starter

The 450 Rancher is the usual recommendation for homeowners whose trees stay under about 14 inches. It starts easily, balances well, and the weight stays manageable. With the 20-inch bar you can fell a 14-inch tree comfortably, but if you routinely work denser wood at the upper end of that range, the extra power of the 455 is worth the step up.

Best for: suburban lots, storm cleanup, firewood on a modest scale.

Skip if: you face dense hardwood above 16 inches.

Pros: easy starting, lighter weight, approachable entry into pro-grade design. Cons: loses speed in large diameter hardwood.

5. Stihl MS 271 Farm Boss: best for easy maintenance and dealer support

Specs: about 50cc · 3.5 bhp · 12.4 lb powerhead · 18 or 20-inch bar · .325-inch chain pitch · inertia chain brake · anti-vibration system

The MS 271 is the Stihl equivalent of the 450 Rancher and is sold through dealers who also offer sharpening and servicing. That support network is the main reason to choose it: a saw you can bring in for a tune-up each season lasts longer than one you run until it fails. Power is similar to the 450 Rancher, so match it to the same tree sizes.

Best for: buyers who want a local dealer relationship and a lighter powerhead.

Skip if: you want a mass-market retail price; dealer saws cost more.

Pros: low powerhead weight, dealer service, durable. Cons: dealer-only purchase in most cases, and similar capability to cheaper Husqvarna options.

6. Stihl MS 291: best Stihl step-up for 14 to 18 inch trees

Specs: about 56cc · about 3.8 bhp · 18 or 20-inch bar · similar powerhead weight to the MS 271 · inertia chain brake · anti-vibration system

The MS 291 adds displacement and power to the MS 271 platform at about the same weight. For hardwood in the 14 to 18 inch range it is a noticeably more confident cutter than the MS 271. Pair it with a 20-inch bar for felling and a sharp chain, and keep a spare chain in the truck.

Best for: Stihl buyers who cut larger hardwood.

Skip if: you only cut small trees; save weight and money with the MS 271.

Pros: power without extra weight, dealer service. Cons: similar to the 455 Rancher in capability but typically dearer.

7. Poulan Pro PR5020: best entry-level 20-inch saw

Specs: 50cc · 20-inch bar · about 15.4 lb · inertia chain brake · hard-sided storage case

The PR5020 is an entry-level way to get a 50cc engine and a 20-inch bar for occasional felling of small to medium trees. It weighs more than the Husqvarna and Stihl saws of the same displacement and does not carry the same long-term parts and service reputation, which is why it sits below them. For a few trees a year, that trade-off is reasonable.

Best for: occasional use on trees under 14 inches.

Skip if: you plan weekly use or cut dense hardwood.

Pros: low entry cost, included case. Cons: heavier, less refined vibration control.

8. Prorun PCS218: budget 18-inch option for light felling

Specs: 45cc · 18-inch bar · about 15 lb · inertia chain brake · onboard scrench storage

The PCS218 is the smallest saw on this list. It can fell small trees up to about 12 inches and clear storm limbs, but 45cc is at the low end for an 18-inch bar in hardwood. Treat it as a light-duty saw and let the chain do the work with a sharp edge rather than forcing it.

Best for: small yard trees and storm cleanup on a tight budget.

Skip if: you have hardwood trunks above 12 inches.

Pros: lowest entry cost, 18-inch bar. Cons: underpowered for large trees, heavier than its displacement suggests.

Safety gear you need before the first cut

Treat the gear below as non-negotiable. It is separate from the saw and often costs less than the saw, but it prevents the most severe injuries.

• Helmet system: a forestry helmet with a face screen and hearing protection, rated for chainsaw use. Falling dead limbs, called widowmakers, are a leading cause of felling injuries.
• Chainsaw chaps or pants: look for protective layers that clog the chain on contact. Check the label for the relevant standard.
• Boots: steel-toe chainsaw boots with cut-resistant material and good ankle support.
• Gloves: snug gloves with cut-resistant protection on the back of the left hand.
• Wedges and a felling axe or mallet: plastic wedges stop the bar from pinching and help direct the fall.
• First-aid kit with a tourniquet: keep it in reach, and never work alone.

Felling logic in six steps

1. Assess the tree. Look for dead limbs, rot, a heavy lean, power lines, structures and neighbors. If any tree can strike a line or building, stop and hire a professional.
2. Clear a drop zone. The danger zone is about two times the tree height. Keep people and pets out.
3. Plan two escape paths. Clear brush and trip hazards along paths angled roughly 45 degrees back from the planned fall line, and clear them before you cut.
4. Cut the notch. Make a notch on the fall side, about one fifth to one third of the trunk diameter deep, with a cut angle around 70 to 80 degrees, so the tree has a direction to fall.
5. Make the back cut. Cut from the opposite side, slightly above the base of the notch, and leave an uncut hinge of wood about one tenth of the diameter. The hinge guides the fall. Insert a wedge as soon as the bar is deep enough.
6. Retreat. As soon as the tree starts to move, shut off or set the saw down with the brake on and walk away along an escape path. Do not watch from the base.

If the tree sits on its stump, hangs up in another tree, or pinches the bar, stop. Do not cut a hung tree free; call a professional. Never cut above shoulder height.

Gas chainsaw maintenance that keeps felling safe

• Use fresh fuel mixed to the ratio in the manual, and use a premixed or stabilized fuel if the saw sits for weeks.
• Keep the chain sharp. A dull chain produces fine dust instead of chips, pulls toward the cut, and invites kickback.
• Check chain tension on a cold saw and recheck after the first cuts.
• Keep the bar oil reservoir full, and never run the saw dry.
• Check the chain brake at the start of each session by engaging it and revving briefly.

Frequently asked questions

What size chainsaw do I need to cut down a tree?

Choose a bar at least four inches longer than the trunk diameter. A 16-inch tree needs a 20-inch bar. Power matters too: 50cc handles small trees, 55 to 60cc handles large hardwood.

The reason for the four-inch rule is that the first few inches of bar sit inside the saw body, and you want margin beyond the far side of the trunk to avoid burying the tip.

Is a 20-inch bar too big for a homeowner?

No, a 20-inch bar is the most common homeowner felling length. It suits trees up to about 16 inches when paired with a 50 to 60cc engine. Use shorter bars for limbing and light work.

The key is matching the bar to the engine. A 20-inch bar on a 40cc saw is underpowered, but on a 55cc saw it is well balanced.

Is gas or battery better for cutting down trees?

Gas is still the better choice for sustained felling of trunks above 12 inches, because it delivers runtime and torque without battery limits. Battery saws suit small trees, limbing and quieter yards.

High-voltage battery saws are improving, but for a long afternoon of felling and bucking, a gas saw with a spare chain remains the more flexible tool.

What safety gear is mandatory for felling?

At minimum you need a chainsaw helmet with face screen and hearing protection, chainsaw chaps, cut-resistant gloves and steel-toe chainsaw boots. Carry a first-aid kit and never fell alone.

The helmet is the item people skip most often, yet falling limbs are among the most common causes of serious felling injuries.

How deep should the notch be?

The notch should reach roughly one fifth to one third of the trunk diameter. It is cut on the side the tree should fall, at an angle of about 70 to 80 degrees.

A notch that is too shallow gives the tree too little direction, and one that is too deep weakens the trunk before you make the back cut.

When should I hire a professional instead?

Hire a certified arborist if the tree is near power lines or buildings, is larger than about 24 inches in diameter, shows rot, or leans toward a hazard. Do the same for any hung tree.

The cost of a professional is small compared with the cost of damage or injury when a felling plan has no safe drop zone.

What is kickback, and how do I reduce it?

Kickback is a sudden upward or backward motion of the bar when the upper tip contacts wood. Reduce it with a sharp chain, firm grip, the chain brake, and by never cutting with the tip.

Low-kickback chains and a guard on the bar nose reduce the risk but do not remove it, so technique and protective gear remain essential.

How often should I sharpen the chain?

Sharpen whenever the saw produces fine dust instead of chips, pulls to one side, or needs force to cut. In practice, touch up the chain at each refuel and replace it when the teeth are worn short.

Dirt and hitting the ground dull a chain within minutes, so stop and sharpen rather than pushing through.
