Stihl HSA 66

The STIHL HSA 66 Lithium-Ion hedge trimmer features a 36-volt lithium-ion battery and delivers strong, quiet cutting performance. Another tool in the STIHL Battery-Powered Equipment line, the HSA 66 runs on the same universal battery shared by all battery-powered tools. Its energy-efficient design allows for up to 40% longer run times when compared to the previous model. As always, there’s no gradual drop in performance —it runs at full power until the battery is fully depleted. The HSA 66 is also a full pound lighter than the previous model, making it less fatiguing and easier to maneuver for landscaping professionals. Because there is no gasoline, no fuel cost, and no restrictive power cords, the HSA 66 delivers an excellent combination of performance and efficiency. The STIHL HSA 66 also has no engine exhaust emissions and is four times quieter than its gasoline-powered equivalent, making it an excellent alternative in environmentally sensitive areas.

The HSA 66 features optimized blade geometry and diamond-ground blade edges for clean cuts, even through thick and tough shrubbery. The 20” blade length is an efficient working length for most applications and a tip protector helps protect blade tip from damage. The HSA 66 lithium-ion hedge trimmer is a great choice for professionals interested in both controlled sculpting and general hedge trimming tasks.
