Handheld leaf blowers are the most popular because they are portable, convenient, and inexpensive. Both gasoline and electric powered models are available. If you have a small yard, they are a good choice, but they can be too heavy to use on a large yard. Backpack leaf blowers are always gas-powered. The blower fits in a harness that you wear on your back, attached to a hose. Backpack blowers are good choices for larger yards. Walk-behind leaf blowers are also gas-powered. They are mounted on wheels and are easy to maneuver. Because they are the most expensive choice for leaf blowers, they are best for very large yards.
