In 1927, Emil Lerp, the founder of Dolmar, developed the world’s first gasoline-powered chainsaw and mass-produced them.World War II interrupted the supply of German chain saws to North America, so new manufacturers sprang up including Industrial Engineering Ltd (IEL) in 1947, the forerunner of Pioneer Saws. Husqvarna chainsaw 3d shirt Ltd and part of Outboard Marine Corporation, the oldest manufacturer of chainsaws in North America. McCulloch in North America started to produce chainsaws in 1948. The early models were heavy, two-person devices with long bars. Often chainsaws were so heavy that they had wheels like dragsaws. Other outfits used driven lines from a wheeled power unit to drive the cutting bar.
After World War II, improvements in aluminum and engine design lightened chainsaws to the point where one person could carry them. In some areas the skidder (chainsaw) crews have been replaced by the feller buncher and harvester.
