Leaf blower

Leaf blowers

A leaf blower, commonly known as a blower, is a device that propels air out of a nozzle to move debris such as leaves and grass cuttings. Leaf blowers are powered by electric or gasoline motors. Gasoline models have traditionally been two-stroke engines, but four-stroke engines were recently introduced to partially address air pollution concerns. Leaf blowers are typically self-contained handheld units, or backpack mounted units with a handheld wand. The latter is more ergonomic for prolonged use. Larger units may rest on wheels and even use a motor for propulsion.[1] These are sometimes called "walk-behind leaf blowers" because they must be pushed by hand to be operated. Some units called blower vacs, can also suck in leaves and small twigs via a vacuum, and shred them into a bag.

Leaf blowers are a source of controversy due to their adverse impacts such as operator injury, including hearing loss, particulates air pollution, noise pollution, and ecological habitat destruction.[2] Over 200 localities have restricted the use of leaf blowers and many major cities, including Washington, DC,[3] are implementing total bans due to the negative effects to operator health, ecological destruction, pollution, and nuisances including noise.[4] October 9, 2021, California passed an air pollution control law AB1346 phasing out small off-road engines, like those found in leaf blowers, set to take effect January 1, 2024.[5] They can also be used to blow away thin materials such as clothes
