Homeowners wanted a chainsaw with a 16-inch bar that was powerful enough to tackle yard maintenance and had many of the desirable features found on larger models.
Those features include Stihl’s patented anti-vibration system.
In addition to the anti-vibration system and the QuickStop chain brake feature, the Stihl 021 model also includes Stihl high-quality automatic chain lubrication feature, lateral chain tensioner, and electronic ignition system.
The 16-inch bar of the Stihl 021 is powered by the chainsaw’s single-cylinder, two-stroke engine with its impregnated cylinder bore.
The maximum engine speed with the bar and chain fully engaged is 11,500 rpm and the engine idles at 2,800 rpm.
