Gasoline-powered hedge trimmers are favored by professionals. They're easily the most powerful type of hedge trimmer and are built to withstand hours of use. Although they're usually priced out of range for weekend gardeners, some of the cheaper gas-powered hedge trimmers may be the best choice for homeowners who have large areas to tend frequently.
Among the best-reviewed gas hedge trimmer, the Poulan Pro PP2822 (Est. $170) earns the highest praise from owners. It cuts through shrubbery in half the time that an electric trimmer would, yet it has the portability of a battery-operated model. As one Amazon.com reviewer writes, "a springtime project that normally took several hours with an electric was reduced to 30-45 minutes" with the Poulan Pro PP2822. It features a rotating handle, which allows users to adjust the trimmer so the blade can cut the tops of hedges or get in close to fences or walls. As with most gas-powered hedge trimmer, the Poulan is fairly heavy (15.8 pounds), but it's built to last.
Other top gas models, including the Weed Eater GHT225 (Est. $160) and the Husqvarna 122HD45 (Est. $250) , don't garner the same positive praise that the Poulan Pro does. The Weed Eater in particular earns poor scores for durability. It also struggles with thicker branches and vegetation, and we read some complaints from owners who say it's hard to start. On the plus side, it's lighter than the Poulan (11.6 pounds), making it easier to tote. Unlike the Poulan, the Weed Eater's handle is fixed.
Although considerably more expensive than the other two gas-powered hedge trimmers discussed in this report, experts say the Husqvarna 122HD45 is powerful enough for professionals to use; editors at Popular Mechanics say it's their benchmark for comparing other trimmers. Like the Weed Eater, the Husqvarna's handle cannot rotate. However, there is an insufficient number of reviews to recommend the Husqvarna 122HD45 over the Poulan Pro PP2822, which has a loyal following of reviewers.
