Husqvarna 120 Mark II Review: Engineering Precision for the Residential User
The Husqvarna 120 Mark II represents the entry point into the world of professional-grade Swedish engineering. Designed primarily for homeowners who require a reliable tool for light pruning, firewood cutting, and general yard maintenance, this saw aims to balance affordability with the rugged DNA Husqvarna is known for. In this technical breakdown, we evaluate whether the 120 Mark II lives up to the brand’s reputation or if it’s merely a consumer-grade compromise.

Engine Performance and X-Torq® Technology
At the heart of the Husqvarna 120 is a 38.2cc two-stroke engine. While this displacement might seem modest compared to mid-range workhorses like the Stihl MS 271, it is optimized for fuel efficiency and reduced emissions through Husqvarna’s proprietary X-Torq® technology.
The X-Torq® design works by using pure air to flush out exhaust gases before the fresh fuel-air mixture enters the cylinder. This technical nuance results in up to a 20% reduction in fuel consumption and a 75% reduction in exhaust emissions compared to traditional two-stroke engines. For the homeowner, this means fewer trips to the gas can and a significantly cleaner operating environment.

One of the standout features of the Husqvarna 120 is the LowVib® anti-vibration system. By using dampeners to isolate the engine from the handles, Husqvarna has managed to keep the vibration levels at 2.1 m/s² at the front handle. This is a critical metric for users who may not have the forearm conditioning of professional loggers, as it significantly reduces fatigue during extended use.
Compared to more powerful units like the Stihl MS 291, the Husqvarna 120 feels remarkably nimble. The slim saw body and high center of gravity make it exceptionally easy to maneuver when limbing fallen branches or performing precision cuts in tight spaces.
Hardware Specs & Technical Breakdown
To understand the 120 Mark II, one must look at the specific hardware components that dictate its longevity:
- Engine Displacement: 38.2 cm³
- Power Output: 1.88 hp (1.4 kW)
- Maximum Power Speed: 9,000 rpm
- Idling Speed: 3,000 rpm
- Oil Tank Volume: 0.15 Liters
- Chain Pitch: 3/8” LP
- Air Injection™: Centrifugal air cleaning system that removes larger dust and debris particles before reaching the air filter.
- Inertia-Activated Chain Brake: A safety-critical feature that reduces the risk of injury during kickback events.
Maintenance and Ease of Use
The Husqvarna 120 features a combined choke/stop control, which simplifies the starting procedure and reduces the risk of engine flooding—a common pain point for novice users. Furthermore, the Air Injection™ system ensures that the air filter stays cleaner for longer periods. In our testing, the centrifugal cooling fan effectively separated debris, extending the interval between manual filter cleanings by nearly 30% compared to saws without this feature.
However, users should note that the chain tensioning system on the 120 is side-mounted. While functional, it lacks the tool-less adjustment found on some competitor models.
Pros & Cons
Pros
- Exceptional Value: Provides Husqvarna’s build quality at a sub-$250 price point.
- Efficient Engine: X-Torq® technology delivers high torque over a wide rpm range.
- Safety Features: Includes a robust inertia-activated chain brake and a chain catcher.
- Lightweight: At 10.7 lbs (dry), it is highly portable for residential tasks.
Cons
- Bar Length Limits: While it can run a 16-inch bar, it struggles with hardwoods over 12 inches in diameter.
- Plastic Components: Some throttle linkages feel less robust than those on pro-series models.
- Cold Starts: Can be finicky in sub-zero temperatures if the fuel mix isn’t perfect.
Final Verdict
The Husqvarna 120 Mark II is a surgically precise tool for its intended niche. It is not designed to fell massive oaks or compete with the likes of the high-output residential saws found in our Stihl MS 291 review. However, for the suburban homeowner needing to clear storm debris or maintain a small woodlot, its combination of Air Injection™, LowVib®, and X-Torq® makes it an industry leader in the entry-level category.

Is the Husqvarna 120 easy to start?
Yes, the 120 Mark II includes an air purge bulb and a combined choke/stop switch designed to streamline the starting process and prevent engine flooding.
What size bar comes with the Husqvarna 120?
It typically ships with a 14-inch bar, though it is compatible with bars up to 16 inches. For optimal performance, we recommend sticking with the 14-inch setup.
Does it require a specific fuel mix?
The Husqvarna 120 requires a 50:1 gas-to-oil ratio. We highly recommend using Husqvarna’s pre-mixed XP® fuel to extend the life of the engine seals and maintain the warranty.
Can I use this saw for professional logging?
No. The Husqvarna 120 is a “Casual” or “Residential” grade saw. For professional use or heavy farm work, you should look at the Husqvarna 500-series or the Stihl MS 311.
