The Chain Saw for All Working Conditions

High-Powered, Heavy-Duty

The Husqvarna Rancher Chain Saw is ideal for landowners and part-time users who require a high-powered, heavy-duty and responsive workmate for all cutting conditions. It combines the best technology and ergonomics with a powerful 3.0 cubic inch, 50.2cc, 3.2 HP X-Torq® engine for lower fuel consumption and reduced emissions levels. Air Injection technology provides a centrifugal air cleaning system that removes larger dust and debris particles before reaching the air filter, resulting in reduced air filter cleanings and improved engine life.

User-Friendly Features

With the Husqvarna Rancher Chain Saw, you'll spend more time being productive and less time struggling with your saw, thanks to its host of ergonomic and usability features. To make getting started easy, the saw has a combined start/stop switch, a fuel pump and Smart Start®. You'll get going with minimum effort every time. When you're at work, you'll notice that the LowVib® system reduces the vibration level in the ergonomic handle, so you'll be able to work longer with less fatigue. The saw also has distinct felling marks for precision cuts and a fuel level window. For safety, this chain saw has an inertia-activated chain brake.
