The STIHL 050AV and 051AV are not vehicles, but rather powerful gasoline-powered chainsaws renowned for their durability and performance. These models, initially released in the late 1970s, were designed for professional forestry work, tackling tough tasks like felling large trees and heavy timber processing.
