The Husqvarna 50 Special chainsaw was introduced in 1989 by the Swedish manufacturer Husqvarna Vapenfabriks AB, and it quickly became a popular choice among both professional and amateur users.
This chainsaw was designed to handle heavy-duty tasks, featuring a powerful 51ccm (3.1 cu. in.) engine and sturdy construction made of die-cast magnesium and injection-molded polymer. The Husqvarna 50 Special boasted several impressive features, such as an anti-vibration handlebar system, an inertia-activated chain brake, and an automatic oil pump that delivered 7.0 cc of oil per minute at 6,000 RPM.
This chainsaw came with a recommended fuel-oil ratio of 50:1 and could run on regular fuel. The Husqvarna 50 Special was available with guide bars ranging from 15 to 18 inches, and its color scheme was Husqvarna Orange with a black top. Despite its impressive features, the Husqvarna 50 Special was eventually discontinued, leaving behind a legacy of reliability and performance.
