The STIHL anti-vibration system in chainsaws

An anti-vibration system is a standard part of chainsaws today. But that hasn’t always been true. Back in the old days, the handles were attached directly to the engine of the chainsaw, which meant that users could really feel the vibrations of the machine.
The first one-man saw, the legendary STIHL Contra, revolutionised forestry when it was launched in 1959. The Contra allowed forestry workers to trim trees with a chainsaw instead of an axe for the first time. However, this also meant that chainsaw operators were exposed to higher vibration loads.
