EQUIPMENT OPTIONS: Blown away
Powered blowers have become a standard piece of equipment for anyone in the business of maintaining landscapes. As a matter of fact, most landscape contractors will tell you that blowers are indispensable. Without them, cleaning up even a small yard would take an unacceptable amount of time — time that could be spent getting to another job before the end of the day.
Choosing a blower
With so many makes, models and types of blowers available, it's important to choose the one best suited for how you plan to use it. Backpack blowers are often more powerful than hand-helds, and are better-suited for commercial use in a variety of ways. They have larger fuel tanks and air filters that allow you to use them longer without cleaning or refueling them. Before selecting a blower, consider your useage: Will you use the blower for long periods of time without shutting it off, or will you start and stop it several times during the course of one job? Also think about how powerful you really need it to be: Will you be using it to sweep piles of wet leaves, or will you be using it to just clear sidewalks and driveways of grass clippings? Generally, backpack blowers are geared toward landscape contractors, offering more power and larger fuel tanks for longer use.
One of the most important things to consider before purchasing a blower is how quiet you need it to be. Many cities have ordinances that impose noise restrictions and stipulate maximum-acceptable decibel levels, so it is important to check with city hall before you select a blower.
Americans' No. 1 neighborhood complaint — above crime, traffic and poor public service — is noise. Every day, more than 138 million Americans experience noise levels that the U.S. Environmental Protection Agency (EPA) rates as “annoying and disruptive.” Among city-dwelling Americans, 87 percent are exposed to noise so loud that it has the potential to degrade hearing capacity over time.
The Occupational Safety and Health Administration (OSHA) considers noise above 85 decibels dangerous. To put this in perspective, 78 decibels is louder than most alarm clocks, and every 10-decibel increase represents a doubling of the loudness.
Blower manufacturers are aware that noise level is one of the most important factors customers consider when purchasing a blower, and most seem to be heeding the call for quietness. According to tests conducted by Consumer Reports, “…most gas-powered leaf blowers are indeed quieter than they used to be.”
Even if your city currently has no restrictions on noise, it is a good idea to look for blowers that have decibel ratings in the 60s or 70s. These are levels that satisfy many communities' standards, should your city decide to impose noise-related ordinances in the future.
Backpack blowers generally have engine displacements of 30 to 60-plus cc. These engines can generate air velocities of 160 to 250 mph, with air volume of 400 to 640 cfm. Some of the more powerful models — those with blowing power of 190 mph or more — can easily clear heavier debris, such as piles of wet leaves, and even move bricks. However, if you're just looking to clear light debris from hard surfaces, such as patios and sidewalks, power is not as important. You'll want to choose a blower with a smaller engine (about 40 cc) that is capable of blowing air at 160 to 180 mph.
Backpack blowers are some of the easiest equipment to handle and operate. Most of them are relatively lightweight, weighing in at around 20 pounds. Look for models that offer adjustable throttle controls that lock into position for easy starting. Also look for a padded harness that will reduce vibration. Harness design and comfort will vary, so be sure to try on the blower and make sure it's comfortable to you before you buy it.
What a difference a few years can make. No matter what kind of chore you have to do, manufacturers are making sure you can do it faster and more comfortably than ever before.
