When it comes to high-performance chainsaws, two names dominate the professional logging and forestry world—Husqvarna and Stihl. These brands have built a legacy on durability, power, and innovation. Among their top-tier offerings, the Husqvarna 592 XP and the Stihl MS 660 stand out as giants. But which one is better suited for the toughest jobs? In this comparison, we’ll break down their specifications, performance, ergonomics, and overall value to help you decide which chainsaw best meets your needs.
Engine Power and Performance
The Husqvarna 592 XP is a newer model designed to deliver high performance under intense working conditions. It features a powerful 92.7cc engine that produces approximately 7.6 horsepower. With a maximum speed of around 9,600 RPM, the 592 XP is built for cutting large hardwoods with precision and speed. It is ideal for felling, bucking, and other professional forestry tasks.
The Stihl MS 660, on the other hand, is a classic powerhouse that has earned the trust of professional loggers for decades. With a 91.6cc engine and about 7 horsepower, the MS 660 offers slightly less displacement than the 592 XP but is still an incredibly robust machine. Its reliability and proven track record make it a go-to for many.
Winner: Husqvarna 592 XP, for slightly more engine power and advanced engineering.
Weight and Handling
Chainsaws of this size can be heavy, and operator fatigue becomes a serious consideration. The Husqvarna 592 XP weighs approximately 16.3 pounds (without the bar and chain), while the Stihl MS 660 comes in slightly lighter at around 14.6 pounds. The difference might not seem huge, but after a full day of work, those extra pounds can matter.
However, weight is only part of the equation. The 592 XP features Husqvarna’s LowVib® anti-vibration system, which significantly reduces strain on the hands and arms. This contributes to better handling and greater comfort over long periods of use. The MS 660 also has a vibration-reduction system, but it isn’t quite as advanced as Husqvarna’s latest version.
Winner: Tie — The MS 660 is lighter, but the 592 XP offers better vibration control.
Cutting Capacity and Bar Compatibility
Both chainsaws are compatible with long guide bars, which is essential for heavy-duty logging. The Husqvarna 592 XP supports bars from 20″ to 36″, offering flexibility for both smaller and very large cutting jobs. Its cutting speed, paired with the X-Cut® C85 or C83 chains, delivers a fast and clean cut.
The Stihl MS 660 supports guide bars from 20″ to 36″ as well, and with the right chain, it can chew through thick logs effortlessly. It’s worth noting that the MS 660 is widely used in competitive chainsaw events, which speaks to its raw cutting power and user familiarity.
Winner: Draw — Both offer excellent cutting performance and bar flexibility.
Technology and Features
Husqvarna has equipped the 592 XP with a range of modern features, including AutoTune™ 3.0, which automatically adjusts the engine settings for optimal performance based on environmental conditions. This means less time tuning the carburetor and more time cutting. It also includes a highly efficient air filtration system and a digital start system that simplifies the ignition process.
The Stihl MS 660, being an older model, doesn’t include the same level of smart technology. It features a traditional carburetor and mechanical tuning, which some users actually prefer for its simplicity and ease of field repair.
Winner: Husqvarna 592 XP — Advanced technology and better efficiency.
Maintenance and Durability
Durability is where both brands shine. The Stihl MS 660 is known for its rugged build and long service life. It can handle years of abuse in tough forestry environments, and spare parts are widely available. Mechanics and users alike appreciate how easy it is to service.
The Husqvarna 592 XP is designed with similar goals in mind. It features a durable magnesium crankcase, a heavy-duty air filtration system, and tool-less access to air filters and spark plugs. With regular maintenance, it promises an extended lifespan.
Winner: Tie — Both chainsaws are extremely durable with excellent service support.
Fuel Efficiency and Emissions
Modern forestry tools must balance power with environmental responsibility. The Husqvarna 592 XP excels in this area with its X-Torq® engine technology, which significantly reduces fuel consumption and emissions. Users report noticeable savings on fuel, especially during long shifts.
The Stihl MS 660, while powerful, belongs to an earlier generation of chainsaws. It consumes more fuel and emits higher levels of exhaust, though still within acceptable limits for heavy-duty equipment. Stihl has since released more eco-friendly versions, such as the MS 661 C-M.
Winner: Husqvarna 592 XP — Better fuel economy and lower emissions.
Price and Value
Pricing for both saws can vary by region and dealer. The Stihl MS 660 (or its successor, the MS 661 C-M) tends to be slightly more affordable, especially on the secondhand market. Its longstanding reputation and simpler mechanics also make it attractive to budget-conscious buyers.
The Husqvarna 592 XP generally comes with a higher price tag due to its new design, advanced features, and cutting-edge technology. However, for professionals who want the best performance and efficiency, it may be worth the investment.
Winner: Depends on budget — Go for MS 660 if you want savings; choose 592 XP for cutting-edge performance.
Conclusion: Which One Should You Choose?
