A chainsaw can look perfect under bright shop lights, yet its real character appears beside a cold log pile. The starter cord must pull cleanly, the engine must settle into a steady note, and the chain must keep moving when the bar enters hard wood. That is where one STIHL model has built a broad following among homeowners, farmers, and rural landowners.
The STIHL MS 271 FARM BOSS is the strongest answer to the question, “What is the best-selling STIHL chainsaw?” STIHL includes the 18-inch MS 271 on its current U.S. bestseller page, and the saw sits in the middle of the range where many buyers shop. It is strong enough for regular firewood cutting and storm cleanup without the price or weight of a large forestry saw. STIHL does not publish model-by-model sales totals, so no public unit count proves a permanent number-one model.

1. STIHL MS 271 FARM BOSS: Best-Selling STIHL Chainsaw Overall
The MS 271 FARM BOSS lands in the part of the chainsaw market where power, price, and weight meet. Its 50.2 cc engine produces enough force for firewood rounds, fallen limbs, storm debris, fence-line trees, and medium trunk cutting. The bare powerhead weighs about 12.3 pounds before the bar, chain, fuel, and chain oil are added.
Many buyers choose the 18-inch model. That bar length gives the saw good reach while keeping the front end manageable. The 20-inch version suits wider logs, though the extra bar and chain add nose weight. The longer setup also asks more from the engine when the whole bar sits inside dense hardwood.
The MS 271 is not a lightweight pro saw. Its body feels heavier than the MS 261, even though both sit near the 50 cc mark. The trade is price. The MS 271 gives farm and ranch owners strong gas cutting without the higher cost of STIHL’s pro line.
A pre-separation air filtration system removes heavier dirt before air reaches the main filter. This helps the filter stay cleaner during dry firewood work. A side-access chain tensioner lets the owner adjust chain slack from the sprocket-cover side. The fuel and oil caps open without a separate wrench.
The FARM BOSS name also carries weight with rural buyers. It has been attached to STIHL saws for years, and many owners replace an older FARM BOSS with the newer model they already know. That history gives the MS 271 a familiar place in barns, sheds, and pickup beds.
Choose the MS 271 when you cut several loads of firewood each year, clear storm damage, care for acreage, or fell medium trees. It is more saw than a suburban owner needs for light pruning, but it is a sound middle choice for regular gas-powered work.
Why the MS 271 Sells So Well
The MS 271 does not win by being the lightest, fastest, or most powerful STIHL saw. It sells because it covers the jobs that many chainsaw owners face. Most private buyers do not cut giant timber every day. They need one machine for heating wood, fallen branches, rough property care, and the occasional tree.
Its price also sits below the pro range. Buyers can step above a small homeowner saw without paying for a machine built for daily forestry shifts. That middle position is much like a half-ton pickup. It may not carry the largest load on the road, but it handles ordinary rural work without feeling wasteful.
Dealer access helps too. STIHL sells through authorized local dealers rather than relying only on warehouse shipping. A dealer can assemble the saw, set chain tension, explain the controls, and match the bar and chain to the buyer’s work.
That shop relationship matters later. Chains wear, bars develop rail damage, sprockets need replacement, and fuel systems may need service after long storage. A nearby dealer can keep an older saw working long after the first chain has been filed down.
2. STIHL MS 250: Longtime Homeowner Favorite
The MS 250 is another model on STIHL’s U.S. bestseller page. STIHL calls it a customer favorite, and it has remained in the range for many years. Its 45.4 cc engine and 10.1-pound powerhead give it a lively feel for home firewood and land care.
This saw is lighter than the MS 271 by more than two pounds at the powerhead. That gap becomes easy to feel during limbing, loading, and repeated cuts. The MS 250 moves through branches with less strain, and an 18-inch bar gives it enough reach for common home use.
The MS 250 works well for fireplace logs, downed branches, small trees, and seasonal cleanup. It can cut larger wood when the chain is sharp, but it does not have the same steady pull as the MS 271 in a broad hardwood round.
Cold starting can take practice. The operator must follow the choke steps and move the control after the first engine response. Leaving the saw on full choke for too many pulls can flood it. Once the starting routine becomes familiar, the design feels direct and simple.
Choose the MS 250 when weight matters more than extra engine force. It is a fine match for homeowners who cut moderate amounts of wood and do not need a heavy farm saw.
3. STIHL MS 261 C-M: Best Upgrade for Frequent Cutting
The MS 261 C-M is the model many experienced owners buy after using a farm saw. It has a 50.2 cc engine like the MS 271, yet its powerhead weighs only about 10.8 pounds. It also produces more cutting force.
That difference changes how the saw feels in wood. The MS 261 C-M reaches chain speed quickly, pulls hard through a full cut, and turns easily during branch work. It feels more like a sharp knife than a heavy cleaver.
The M-Tronic system manages fuel delivery as temperature, altitude, fuel quality, and filter condition change. The operator does not need to adjust carburetor screws during normal work. This is useful for crews that move between seasons or work across changing elevations.
An 18-inch bar gives the MS 261 C-M excellent balance. A 20-inch bar suits wider timber. The engine can handle either setup, though the shorter bar gives faster acceleration and less front weight.
The higher price will not make sense for a buyer who cuts twice each year. It becomes easier to justify when the saw runs every weekend or earns money. Lower weight can spare the arms and back over hundreds of cuts.
4. STIHL MS 391: Best for Buyers Who Need More Than a FARM BOSS
The MS 391 steps into the 64 cc class. It suits large properties, thick firewood, farm timber, and trunks that keep a 50 cc saw working near its limit.
A 20-inch bar gives it a strong all-round setup. A 25-inch bar adds reach for broad trees and deep bucking cuts. The larger engine carries the extra chain with more authority than the MS 271.
The MS 391 weighs more, burns more fuel, and takes more effort to move between branches. Those costs make little sense for small logs. They make far more sense when oak rounds regularly measure 18 to 24 inches across.
Buy the MS 391 when large wood is normal rather than rare. A shorter, lighter model will be more pleasant for branch work, but the MS 391 will spend less time struggling inside a wide trunk.
5. STIHL MS 500i: Best Premium STIHL Chainsaw
The MS 500i is not the top seller by unit count, but it is one of STIHL’s best-known premium saws. Its 79.2 cc engine produces 6.8 horsepower, while the powerhead weighs about 14 pounds.
Electronic fuel injection gives it a fast response when the throttle opens. The chain rises to cutting speed quickly, which helps during felling, bore cutting, and repeated bucking. A 25-inch or 28-inch bar gives the saw a strong balance for large tree work.
The MS 500i belongs with forestry crews, tree services, land-clearing teams, and serious woodland owners. Its high price and cutting force are hard to justify for ordinary yard work.
A buyer building a two-saw package could pair an MS 261 C-M with an MS 500i. The smaller machine handles branches and medium wood. The MS 500i takes over when the main trunk calls for a longer bar.
6. STIHL MSA 70 C-B: Best-Selling Style for Battery Buyers
Gas models still hold a strong place in the STIHL range, but battery saws fit many home jobs better. The MSA 70 C-B uses a 12-inch bar and the STIHL AK battery system.
There is no fuel to mix, starter cord to pull, or carburetor to clean. Fit a charged battery, check the bar oil, release the chain brake, and press the trigger. The saw becomes silent as soon as the trigger is released.
The MSA 70 C-B suits pruning waste, small trees, storm branches, campfire-size wood, and light firewood cutting. It is easier to store than a gas model because there is no fuel tank to drain.
Battery run time changes with log width, wood hardness, temperature, chain condition, and battery size. Thick wet hardwood drains a pack faster than narrow dry pine. A second charged battery helps during larger cleanup jobs.
MS 271 vs. MS 250
Choose the MS 271 when you cut larger logs, work more often, or want a 20-inch bar. Its extra engine force suits farm chores and steady firewood production.
Choose the MS 250 when low weight matters most. It is easier to carry and better suited to small trees, branches, and moderate firewood work.
The MS 271 is the better single saw for acreage. The MS 250 is the friendlier home model. A buyer with shoulder trouble or limited upper-body strength may be happier with the lighter saw even when the larger machine cuts faster.
MS 271 vs. MS 261 C-M
The MS 271 costs less and suits regular private work. The MS 261 C-M costs more but weighs less, cuts faster, and is built for higher work volume.
Farm owners who cut a few weekends each season will usually get enough saw from the MS 271. Firewood sellers, woodland crews, and tree workers will gain more from the MS 261 C-M.
Both models work well with an 18-inch bar. The MS 261 C-M feels quicker and lighter. The MS 271 feels steadier and less costly to buy.
Best Bar Length for a Best-Selling STIHL Chainsaw
An 18-inch bar is the best match for the MS 271. It covers common firewood and property work while keeping the saw balanced. The bar can cut a trunk wider than 18 inches by working from both sides, provided the operator has the training to make those cuts safely.
A 20-inch bar gives more reach but adds chain drag and nose weight. It makes sense when wider logs appear often. Buyers who rarely cut wood above 16 inches will gain little from the added length.
For the MS 250, a 16-inch or 18-inch bar is the better choice. For the MS 261 C-M, 18 inches gives quick handling, while 20 inches suits larger timber.
Premium STIHL Chainsaw Package Over $2,000
A high-end STIHL package can pass $2,000 without buying the largest saw in the range. Pair an MS 261 C-M with an MS 500i for a two-machine cutting setup. The smaller saw handles limbing and normal trunks. The larger saw carries long bars through broad timber.
Add spare guide bars, six or more chain loops, round files, a flat file, depth-gauge guides, felling wedges, a cant hook, approved fuel containers, chain oil, and hard carrying cases.
Protective clothing belongs in the same budget. Pack a forestry helmet, face screen, hearing protection, chainsaw chaps, gloves, and cut-resistant boots. Keep a bright first-aid case close to the cutting area.

Where Should You Buy a STIHL Chainsaw?
Buy a new STIHL chainsaw from an authorized STIHL dealer. The dealer can confirm the correct model, assemble the cutting gear, check chain tension, and explain the starting controls.
Be careful with marketplace listings that claim to sell new STIHL powerheads. STIHL warns buyers about unauthorized online sellers and counterfeit machines. A low price is no bargain when the saw has no dealer backing or genuine safety parts.
Amazon is a better place to shop for compatible protective clothing, sharpening gear, wedges, cases, and log-handling equipment. Check bar mount, chain pitch, chain gauge, and drive-link count before ordering replacement cutting parts.
Which Best-Selling STIHL Chainsaw Should You Buy?
The STIHL MS 271 FARM BOSS is the best answer for buyers seeking the best-selling STIHL chainsaw. It appears on STIHL’s current U.S. bestseller page and fits the needs of a broad group of owners. It can cut heating wood, clear storm damage, maintain acreage, and fell medium trees without stepping into pro-saw pricing.
The MS 250 is the better choice for lighter home work. The MS 261 C-M is the stronger upgrade for frequent cutting. The MS 391 suits large logs, while the MS 500i belongs in paid forestry and tree work.
For most rural owners, the MS 271 with an 18-inch bar is the sweet spot. It has enough force to bite into real timber, yet it does not carry the weight or cost of a large logging saw. That broad usefulness is the reason it continues to stand near the front of the STIHL range.
