When it comes to professional-grade chainsaws, two models often mentioned in the same breath are the Stihl MS 660 and the Husqvarna 390 XP. Both are high-performance machines designed for the toughest logging and forestry tasks. While they may seem similar at first glance, these saws have unique characteristics that can make one more suitable than the other depending on the user’s needs. In this article, we’ll compare the Stihl MS 660 and the Husqvarna 390 XP in detail, focusing on performance, design, features, handling, and overall value.
Engine Power and Performance
The Stihl MS 660 is built for raw power. It is equipped with a 91.6 cc engine that delivers 7.0 horsepower, making it ideal for heavy-duty applications like felling large trees and cutting thick logs. It’s known for its aggressive cutting capability and ability to power through the hardest wood without bogging down.
On the other hand, the Husqvarna 390 XP features a 88 cc engine with 6.5 horsepower. While slightly less powerful on paper, it holds its own impressively in practical use. Thanks to Husqvarna’s X-Torq® engine technology, the 390 XP offers excellent fuel efficiency and reduced exhaust emissions without compromising performance. It also has a reputation for smoother and more controlled power delivery.
Verdict: If raw cutting power is your top priority, the MS 660 may have the edge. But if you’re looking for fuel efficiency with solid performance, the 390 XP is a strong contender.
Design and Build Quality
Stihl is known for robust, durable construction, and the MS 660 is no exception. It has a solid magnesium housing and is built to endure the rigors of professional forestry work. Its design is straightforward and functional, aimed at reliability and strength.
The Husqvarna 390 XP also boasts excellent build quality, but with a slightly different philosophy. It emphasizes ergonomics and ease of use more than sheer ruggedness. The body is slim, and the handle positioning is optimized for operator comfort. This makes a big difference in fatigue levels during long workdays.
Verdict: Both chainsaws are built tough, but if comfort and ease of handling are important to you, the Husqvarna takes the lead.
Weight and Handling
In terms of weight, the MS 660 tips the scale at around 16.3 lbs (7.4 kg) without bar and chain. That makes it a hefty machine, and it can be tiring to use for extended periods, especially for overhead work or limbing.
The Husqvarna 390 XP is slightly lighter, weighing approximately 15.4 lbs (7.0 kg). Combined with better weight distribution and ergonomic handle placement, it feels more balanced during operation. Vibration reduction is also better in the 390 XP thanks to its LowVib® system, which helps reduce operator fatigue.
Verdict: Husqvarna wins this round for having better ergonomics and lower vibration levels, making it easier to handle over time.
Starting System and Maintenance
Both models come with efficient starting systems. The MS 660 uses ElastoStart, which helps reduce the shock from the compression build-up when pulling the starter cord. It’s reliable but still requires a firm pull.
The 390 XP features Smart Start®, a system that reduces resistance in the starter cord, making it significantly easier to start, especially in cold conditions. Many users find it quicker and more convenient to get running than the Stihl.
Maintenance-wise, both saws are designed for professional users and include accessible air filters, chain tensioning systems, and durable components. The Stihl MS 660 features a side-access chain tensioner, while the Husqvarna 390 XP uses a similar setup but also integrates a better air injection system that keeps the filter cleaner for longer.
Verdict: The Husqvarna 390 XP offers a more user-friendly start-up experience and slightly better maintenance features.
Bar Length and Cutting Capabilities
Both saws support long bars for large-scale cutting. The MS 660 is compatible with bars from 20 to 36 inches, making it highly versatile. It’s a go-to saw for large-diameter tree work.
The 390 XP supports bar lengths of 18 to 36 inches, giving it a similar level of flexibility. However, its slightly less powerful engine might not handle the longest bars as effortlessly as the MS 660 in very dense or hardwood conditions.
Verdict: For maximum bar length and large-tree performance, the MS 660 gets a slight edge.
Fuel Efficiency and Emissions
Stihl’s 2-stroke engines are known for power, but not necessarily for fuel economy or emissions control. The MS 660 consumes fuel quickly under heavy load, and although it meets emissions standards, it’s not the cleanest running saw.
In contrast, Husqvarna’s X-Torq® engine is designed with efficiency in mind. It uses less fuel and emits fewer pollutants, making it more environmentally friendly and cheaper to run over time.
Verdict: If you want to save on fuel and reduce your carbon footprint, the Husqvarna 390 XP is the smarter choice.
Durability and Longevity
Professionals trust both of these saws for their durability. The MS 660 has been a long-time favorite in the logging industry, known for taking a beating and continuing to perform reliably. It’s the kind of saw that can last decades with proper care.
The 390 XP also has a strong reputation for longevity. Its air filtration and cleaner burning engine might even extend the life of the internal components. Still, it’s newer in design compared to the MS 660, which has a longer track record in the field.
Verdict: Both are built to last, but the MS 660 has a slightly longer-standing reputation.
Price and Value
In terms of price, the MS 660 typically comes with a higher price tag, especially if purchased new from a dealer. Its reputation and brand recognition contribute to its premium pricing.
The Husqvarna 390 XP is slightly more affordable while offering similar capabilities. For many users, it delivers excellent value, especially when considering the fuel savings and comfort it offers.
Verdict: If budget matters, the Husqvarna 390 XP gives you more bang for your buck.
Final Verdict: Which One Should You Choose?
- Choose the Stihl MS 660 if you need maximum cutting power, regularly work with large hardwood trees, and want a chainsaw with a proven track record of rugged durability.
- Choose the Husqvarna 390 XP if you value comfort, easier handling, better fuel efficiency, and a lower overall cost without sacrificing performance.
Ultimately, both chainsaws are top-tier machines suited for demanding professional work. The better choice depends on your specific priorities—whether that’s brute force or ergonomic efficiency. Either way, you’ll be holding a reliable workhorse capable of tackling the toughest jobs.
