Overview
A 20 inch gas chainsaw powered by a 50.2cc, 3.2 HP X-Torq engine, built for bar lengths between 13 and 20 inches. It includes Smart Start for easier pull-starts, an inertia-activated chain brake, and a centrifugal air cleaning system ahead of the air filter.
This sits above the battery mini-saws in this category by design: a 50.2cc gas engine and a 20 inch bar are built for firewood cutting and larger tree work, not small-branch pruning. X-Torq is Husqvarna's engine technology aimed at lower fuel consumption and emissions without sacrificing power, and the air injection system is meant to extend intervals between air filter cleanings by filtering out larger debris first. No reviews accompany this listing, so real-world starting ease and vibration levels are manufacturer claims rather than confirmed results.

- 50.2cc, 3.2 HP X-Torq engine
- Smart Start pull-start system
- Inertia-activated chain brake
Who it's for
Suits anyone doing firewood cutting, yard cleanup or tree pruning that requires more power and bar length than a battery mini-chainsaw offers. Overkill for occasional light pruning of small branches, where a smaller electric saw would be lighter and simpler.
Strengths and trade-offs
Drawn from this product's published specifications.
- 50.2cc, 3.2 HP engine suited to firewood and larger limbs
- Smart Start reduces pull-start effort
- Inertia-activated chain brake for kickback protection
- Centrifugal air cleaning extends air filter life
- No reviews yet to confirm starting ease or vibration levels in practice
- Gas engine requires fuel mixing and more maintenance than a battery saw
- Heavier than needed for light pruning
Performance notes
The X-Torq engine design is aimed at pulling more work from the same fuel while running cleaner than a standard 2-cycle engine, and Smart Start reduces the pull force needed to get it running. The centrifugal air cleaning system filters larger dust and debris out before it reaches the air filter, which should stretch the interval between filter cleanings. The inertia-activated chain brake is a kickback safety feature that engages from the bar's own momentum rather than requiring the operator to react in time.
