Husqvarna 61 vs. Stihl MS 261 (Bench Test)

The Husqvarna 61 has more displacement, at 61.5 cm³, but the MS 261 is rated slightly higher at 3.0 kW versus about 2.9 kW. Those figures do not prove which cuts faster. The right choice depends on the saw’s condition, matched bar and chain, and your work. A fair bench test must measure both; I won’t invent cut times.

If you have several tabs open, these two saws can look easier to compare than they are. One has a larger engine; the other has a slightly higher stated power rating. But these are not interchangeable saws, and the Husqvarna 61’s age and condition can matter as much as its original specifications.

I compare them by separating published data from measured results. Since no controlled cut-time or fuel-use data is available here, this is a specification-based comparison and a practical test plan, not a report of a completed head-to-head bench test. That distinction helps you judge what the numbers can—and cannot—tell you.

Specification Comparison: Husqvarna 61 vs. Stihl MS 261

This section compares the engines and fitment details that can be stated without assuming every saw is in the same condition. Displacement describes engine size; rated power describes output under the maker’s stated test conditions. Neither number alone predicts your cutting speed.

The MS 261’s stated power is marginally higher despite its smaller displacement. That does not establish a cutting winner. A sharp, correctly matched chain, sound engine, and suitable bar all affect the result. A worn or poorly tuned Husqvarna 61 may perform far below its original capability; the same is true of a neglected MS 261.

The 61 is often paired with 3/8-in pitch and .058-in gauge chain, but “often” is not a fitment guarantee. MS 261 combinations vary by market and bar. Pitch, gauge, and drive-link count must match the bar and drive sprocket. Check the bar stamp and chain markings, then verify the required link count before buying or fitting a chain.

What a Fair Bench Test Can Establish

A bench test is a controlled comparison of the same task under matched conditions. To compare these saws fairly, the test must hold wood, chain sharpness, bar setup, and measurement method steady. Without those controls, a faster cut may reflect a sharper chain or healthier saw, not a better model.

I would record cut time, engine speed, and fuel use only if each can be measured with suitable tools. Use sound wood of the same species, diameter, and moisture condition. Make repeated cuts with both saws, alternating the order to reduce the effect of changing wood or operator fatigue. Note the bar and chain installed on each saw.

Before cutting, check that both engines idle correctly, the clutch disengages at idle, and the oil system delivers lubricant with the bar and chain fitted. Use a tachometer to compare idle and maximum engine speed with the exact manual for each saw. Model generation and market can change the specified limits, so a generic maximum-speed figure is not a safe substitute.

A useful test log includes:

• Saw identification and condition, including any known service history
• Bar length, chain pitch, gauge, drive-link count, and sprocket pitch
• Wood species, diameter, and condition
• Chain sharpness and depth-gauge setting
• Cut time, measured engine speed, and fuel use if measured
• Operator effort and any signs of bogging, poor oiling, or unstable idle

I do not have measured cut times or fuel figures for this comparison, so I cannot say that one saw cut a specific log faster. A repeatable test could answer that question for the exact two saws being considered.

Equipment Setup and Safety Preparation

Safe preparation means confirming that the saw, cutting gear, and operator are ready before testing. A bench comparison is not a reason to bypass guards or safety checks. Both saws need sound controls, matched cutting parts, fresh fuel, and a stable work area before the engine is started.

Inspect the chain brake, throttle interlock, stop switch, chain catcher, handles, bar, chain tension, and oiling system. Wear a helmet, eye and face protection, hearing protection, suitable leg protection, gloves, and protective footwear. Follow applicable ANSI Z133 work practices. Where OSHA logging rules apply, keep the required two-tree-length danger zone, except where the rule permits an exception.

Use fresh gasoline mixed 50:1 with the correct air-cooled two-stroke oil unless the manual for that specific saw directs otherwise. Never use straight gasoline. Fill the bar-oil reservoir with proper bar-and-chain oil; fuel mix and bar oil serve different purposes.

Start each saw using its manual’s cold- or warm-start procedure. Check idle and clutch disengagement before cutting. Compare tachometer readings only with limits in the serial-number-matched manual. Do not tune to a generic wide-open-throttle number or by ear. If the saw cannot be secured for a stationary check without defeating a safety device, do not perform that check in that setup.

Field Cutting and Workload Match

Field use tests how a saw handles a real job, but it only gives a fair comparison when the work is similar. The 61’s larger displacement may appeal for heavier cutting, while the MS 261’s stated power is slightly higher. Neither fact alone tells you which feels better or works faster in your wood.

For comparable cuts, use sound wood of the same species and similar diameter and moisture condition. Keep chain sharpness consistent, maintain a stable stance, use both hands, and keep the bar nose clear. Do not force a dull chain through wood. Record cut time and engine speed, and note whether either saw bogs or needs more operator pressure.

These example setups show how to think about the choice without pretending they are measured case studies:

• Occasional property cleanup: If your work is limited and the Husqvarna 61 is an existing, serviceable saw, inspect its condition and exact fitment before replacing it. A familiar older saw may still meet the task, but age alone cannot confirm reliability.
• Regular mixed cutting: Compare the specific MS 261 and 61 available to you, not just model names. A well-maintained saw with the right chain can be a better buy than a worn example with more displacement.
• Longer or demanding cuts: Match the bar length to the work and each manufacturer’s approved setup. A longer bar does not make a saw more capable by itself; it adds load, and the engine, chain, and wood all affect performance.

Rotational kickback can occur when the upper quadrant of the bar nose contacts wood or another object, driving the bar rapidly up and back. Keep the nose clear, avoid tip-first cuts, maintain a firm two-handed grip, and use a functioning chain brake. The brake does not replace safe technique. Never cut above shoulder height or operate one-handed.

Maintenance, Sharpening, and Tuning

Maintenance affects both performance and the value of a used saw. A clean filter, sharp chain, correct tension, sound fuel system, and working oil delivery help the engine and cutting system do their jobs. Check these items before judging either model by speed or effort.

Set chain depth gauges to the chain maker’s specification. About 0.025 in (0.65 mm) is common, but it is not universal. The wrong setting can change cutting behavior and increase risk. Confirm the chain type and its instructions rather than applying one number to every chain.

After fitting the bar and chain, verify oil delivery. Flow depends on model and adjustment, so there is no universal bench-test rate for these saws. If lubrication appears poor, stop and inspect the oil level, ports, bar groove, and system according to the manual. Do not continue cutting with a dry chain.

After work, stop the engine, allow it to cool, and clean the air filter, clutch-cover area, bar groove, and oil ports. Check chain tension and look for damage before transport or storage. A poor idle, clutch drag, or out-of-range tachometer reading calls for model-specific diagnosis, not an improvised adjustment.

Storage and Seasonal Care

Good storage helps preserve a saw between jobs, but the correct steps depend on the manual and fuel system. Clean the saw, inspect the cutting gear, and follow the maker’s fuel-storage instructions. Keep the chain covered during transport or storage, and do not store a saw with unresolved safety or oiling faults.

Before putting either saw away, remove debris from the bar and cover area, check for damage, and address loose or worn parts. Follow the manual for fuel handling, including whether to drain fuel or use a specified storage method. Do not assume the same procedure applies to every generation or market version.

When bringing a saw back into use, inspect the chain, brake, controls, and oiling again. Start it according to the manual and confirm that the chain stays still at idle. If the saw runs poorly or leaks, diagnose the cause before relying on it for a demanding job.

Which Saw Should You Choose?

Choose by the actual saw’s condition and workload, not the displacement figure alone. The 61 offers more displacement; the MS 261 has a slightly higher stated power rating. Since those ratings do not settle cutting performance, a trustworthy decision should include fitment, service condition, and—if possible—a controlled cut comparison.

For a used Husqvarna 61, confirm that it is serviceable and that its bar, chain, and sprocket match. For an MS 261, identify the exact bar and chain configuration because pitch and gauge can vary. In either case, use the manual tied to that saw’s serial number for speed limits and service instructions.

If you can test both, keep the setup and wood conditions comparable and record the results. If you cannot, buy based on the verified condition of the individual saw, correct parts availability for its configuration, and the work you need it to do. That is a sounder basis than treating a small rated-power difference as a promise of faster cutting.

Frequently Asked Questions

These answers cover the key buying and test questions: power, fitment, fuel, and safe comparison. Exact specifications can vary by generation and market, so use the manual and markings for the saw in front of you rather than relying on a generic model description.

Which saw has more displacement?
The Husqvarna 61 has 61.5 cm³ displacement; the MS 261 has 50.2 cm³.

Which saw has the higher stated power?
The MS 261 is rated at 3.0 kW (4.0 hp), compared with about 2.9 kW (3.9 hp) for the Husqvarna 61.

Which one cuts faster?
Available specifications alone do not establish that. A controlled test needs comparable wood, sharp chains, matched setup, and measured results.

Can I use the same chain on both saws?
Not necessarily. Pitch, gauge, drive-link count, bar, and sprocket must match. Check the bar stamp, chain markings, and manual.

What chain setup is common on a Husqvarna 61?
A common configuration is 3/8-in pitch and .058-in gauge, but verify the parts fitted to the individual saw.

Does the MS 261 use only .325-in chain?
No. MS 261 configurations vary by market and bar, including .325-in or 3/8-in pitch and different gauges. Verify the exact setup.

What fuel mix should I use?
Use fresh gasoline mixed 50:1 with the correct air-cooled two-stroke oil unless the specific saw’s manual gives a different instruction. Never use straight gasoline.

What engine speed should I set?
Use the idle and maximum-speed limits in the serial-number-matched manual and check with a tachometer. Do not rely on a generic setting or tune by ear.
