Whether you’re felling trees, chopping firewood or clearing large patches of land, Husqvarna has a gas chainsaw to complete the job quickly and easily. Our range incorporates models to suit every need, from essential chainsaws for smaller tasks, to market-leading professional models tailored to the most demanding of jobs.

Our gas chainsaw range is designed with versatility in mind. With advanced technological features that help you make light of any challenge, each gas saw can be utilised for a broad spectrum of jobs from casual home and garden use to professional arborist and forestry work. With Husqvarna gas chainsaws, no job is too big or too small.

Our chainsaws are known for their power, but this doesn’t mean you need compromise on efficiency. Robust X-Torq® engines mean every model, from our small gas chainsaws right up to the larger, professional saws in the Husqvarna range, delivers supreme performance and exceptionally low fuel consumption. This means Husqvarna gas saws run for even longer on a single tank of fuel.

The days when gas chainsaws produced excessive noise, emissions and vibrations are gone; Husqvarna champions accessibility and ease of use. LowVib® technology makes handle vibrations as low-impact as possible, while SmartStart® means you can start and stop your chainsaw without the risk of flooding the engine. Alongside other extras such as heated handles, the Husqvarna range helps you work comfortably, whatever the weather.
