When it comes to professional-grade chainsaws, the names Stihl and Husqvarna dominate the conversation. These two manufacturers are legendary in the forestry, landscaping, and logging industries. In this in-depth comparison, we’ll explore three iconic models: the Stihl MS 660, the innovative Stihl 500i, and the dependable Husqvarna 572 XP. Each saw brings something different to the table, and understanding their strengths can help you choose the right one for your heavy-duty cutting tasks.
Stihl MS 660: A Classic Workhorse
The Stihl MS 660 is a legend among loggers. Known for its raw power and simplicity, the MS 660 was designed for felling the biggest trees and cutting through the hardest timber.
Key Features:

- Power Output: Around 7.0 hp
- Weight: Approximately 7.3 kg (without bar and chain)
- Bar Length: Compatible with bars up to 36 inches
- Fuel Capacity: 825 ml
The MS 660 doesn’t feature modern electronic enhancements, but that’s part of its charm. It’s built for those who prefer mechanical reliability over digital components. The saw uses a traditional carburetor system, and though it requires manual tuning, it delivers consistently powerful performance when maintained properly.
This chainsaw is a favorite in remote or rugged environments where simplicity and durability are essential. It’s also appreciated by enthusiasts who restore and preserve older equipment.
Ideal Use:

Stihl 500i: The Game-Changer
Stihl took a bold step into the future with the introduction of the Stihl MS 500i—the world’s first fuel-injected chainsaw. This isn’t just a gimmick; the 500i changes how power is delivered and how responsive a chainsaw can be.

Thanks to its electronic fuel injection system, the 500i starts quickly, even in cold conditions, and adapts to altitude or temperature without manual adjustments. Throttle response is instant, making it feel lighter and more agile in hand despite being close in weight to older models.
Professionals love the 500i for its balance of power and maneuverability. It’s also much easier to maintain than people expect—no carb tuning is required, and diagnostics are simplified through Stihl’s dealer software.
