HSA 66 STIHL Lithium-Ion Hedge Trimmer. 

Product Description

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. And 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. And 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 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.


Run time may vary based on battery type, charge level and capacity, model, operating style and conditions. Batteries and chargers can be purchased separately or as a combined set with tool.

Reviews

HSA 66 is rated 4.9 out of 5 by 27.
Rated 5 out of 5 by from Just what I was looking for I was looking for a battery power hedge trimmer and found the perfect one that runs for a long time and I can change the battery. I was really impressed with the way it cuts small branches and trims so nice. So much better then my old hedge trimmer. I also like that I don’t need to have an electric cord where ever I go with this trimmer. I did get the upgrade battery and the upgrade charger with it and that really charges fast too. Well designed and so glad I bought this one.

Rated 5 out of 5 by from Stihl quality through out. Fast battery charging, about forty-five minute's or so from completely dead battery. Runs about a hour fully charged. Cuts through some pretty thick plant material without missing a beat. Very light weight and agile to use. Would recommend this trimmer.

Rated 5 out of 5 by from Just what I was looking for Great trimmer, it is light and delivers a great deal of power. Works on and on, has a very long run time. I do a lot of trimming on every thing from a weeping Mulberry tree to Pyracantha, and I have yet to run out of charge. On this small farm we have 8 Stihl tools and the dependability just can’t be beat.

Rated 5 out of 5 by from HSA 66 Great trimmer! I bought it to use around a pool, so I would not have an extension cord around the water. I purchased the AP300 battery, and AL300 charger as well. We used it for around 3 hours and still had 75% of the battery life remaining.

Rated 5 out of 5 by from Stihl products are great Just purchased this trimmer a few weeks ago. It does the job great, but the two best things about it are the convenience of a long lasting battery and the weight differential compared to my string trimmer hedge trimmer attachment. I can now reserve that beast for the azeleas that have gotten out of control. The inertia of getting the gas can and heavy trimmer or stretching out all the xtension chords are gone. Don’t see any cut extension chords in my future.

Rated 5 out of 5 by from Great trimmer to have for everyday use. I bought this to trim the edges of my trails on my property. I have been impressed with this unit as it just keeps going I have only charged it once this summer and maintain over 5 miles of trail edges.This cuts through a lot as well without slowing down.

Rated 5 out of 5 by from Replacing a 15 yr old cheap hedge trimmer Finally replaced a 15 yr old hedge trimmer. Had 4 pickup loads of overgrown bushes, this trimmer got the job done on 1 battery charge. Could go through sticks 3/4 inched circumference, very easy to use, women friendly!
