An electronic or gas-powered portable blower. It is primarily intended for the disposal of leaves, grass cuttings and other waste from a lawn into a pile; other applications can involve sweeping driveways or cleaning basements, garages and gutters. Some models have a vacuum mechanism to pull leaves and twigs into a bag; known as blower vacs, they may even include the capacity to ground, turning the leaves into reusable mulch. Most handheld devices have a set plastic nozzle, which can be maneuvered quickly. They are usually, but often the least strong, the lightest and cheapest versions. original site
Gas-powered models are heavier than electric models which range between 7 and 12 pounds. Although their mobility is unrestricted, routine maintenance would be needed. They are fitted with a 2-or4-stroke engine and use an oil / gas combination which is not unlike chainsaws. The motor begins a pull-cord, which is noisy enough to merit ear protection and needs an periodic tune-up.
An electric blower weights normally less than eight pounds. Less intrusive, with an simple start button and no pollution, the power cord is the single limit. An electric blower can be inefficient in a wide environment with several obstacles; it is better adapted for narrower areas where a power supply is within 100 metres. Gas-powered backpack blowers are carried on the back and weigh between 15 and 25 pounds. These are more powerful than portable devices and have the benefit of greater engine strength and a robust compact nozzle. Backpack styles are also preferred by industrial landscapers, by rapidly covering wide fields.
Another sort of blower, just like a lawnmower, is driven on wheels. These gas-powered machines will easily clear a wide region with powerful 4-cycle motors, which can also be tuned to the blowing angle. However, wheeled versions are expensive and cumbersome, and are rarely used in advanced landscaping.
Although leaf blowers are reputed to be loud, that is not the case any more. In the last few years, vendors have introduced changes to the amount of leaf blower noise so that they no longer reflect a noise nuisance.
