There are times when using brooms and rakes is no longer feasible when cleaning ones backyard, front-yard, garage, pathways, outdoor basketball courts, and other facilities. It is a time-consuming and exhausting task to manually clear up piles of leaves and fine debris out of these places. Buying backpack blowers are therefore the ultimate solution for this problem.
This model belongs to a class of power tools called leaf blowers. All backpack blowers are powered by gasoline-run engines and have frames as well as straps that enable you to carry the machine on your back. The factors that you should remember are the engine displacement which is measured in cubic centimeters (cc for brevity), the air velocity measured in miles per hour (mph), and the maximum or average air volume which is measured in cubic feet per minute (CFM). The greater these capacities are, the more powerful a backpack blower is.
These are the most powerful backpack blowers because most four-stroke engines have large fuel displacement capacities. They also generate less smoke emissions since they run on unleaded gasoline. Noise levels are also significantly reduced compared to their two-stroke counterparts.
A good example of a four-stroke backpack blower is the Makita BBX7600. Its 75.6 cc engine produces a maximum air velocity of 195 mph and has a maximum air volume of 526 CFM. Weighing only 22 pounds, it can be used continuously up to 80 minutes without refueling due to its 64 oz. fuel tank capacity.
Lightweight and versatile, these machines are the most commonly used of all backpack blowers. Their engines are less complex than their four-stroke counterparts, thus they are easy to repair. Cooling and fuel systems are integrated due to the simplicity their structure. These require a gasoline-oil mixture to prevent overheating the engine during operation.
An example of backpack blowers powered by a two-stroke engine is Husqvarna 125BT. Its 25 cc engine delivers a maximum air velocity of 150 mph. It also has a maximum air volume of 490 CFM. Using this machine is comfortable because it weighs only 18 pounds.
