This battery-powered hedge trimmer combines great power and long run times. 

Product Description

The HSA 56 hedge trimmer delivers exceptional performance and value. It is portable and lightweight at only 8.1 lbs. (including AK 10 battery), while also packing a performance punch. It features a high cutting speed of 2,800 strokes per minute, slicing through overgrown hedges with minimal vibration. Trim the length of three football fields on a single charge – that’s up to 1,000 feet. And when you’re done, just hang it on the wall from its onboard hanging slot. It’s a great STIHL AK Series hedge trimmer for suburban yard care.

HSA 56 is rated 4.7 out of 5 by 57.
Rated 5 out of 5 by from Absolutely Love It! I run a professional landscape maintenance company. We run all Stihl equipment from the big blowers to trimmers to chainsaws to the biggest Kombi system they make. We also run the largest gas powered hedge trimmer and while it’s a beast, it’s just too big for a lot of the smaller everyday trim jobs. So I decided to give this one a try. Grabbed it and a spare AK20 battery. It’s now become my personal main hedge trimmer. I’ve done everything from Blackberry vines to 100 ft long Thujia hedges with it. The weight is easy on the shoulders...which is important at 54 years old...and it rarely has issues cutting through even larger stuff. I’m happy enough that I’ll be picking up the matching blower and plan to give the trimmer a go (so long as I can put a Speed Feed Head on it!)

Rated 1 out of 5 by from Trimmer continues to lockup between use Not sure if there is a design issue but in spite of application of Stihl hedge trimmer blade cleaner/resin remover before & after each use, blades still lock up. Normally have to loosen all screws and can eventually get unit functioning again. In the latest episode, even screw loosening did not help. Normal residential use of 3-4 times per year. Cannot recommend this model (HSA 56) while this locking up is an issue. Never had similar issue with corded electric trimmer of different brand.

Rated 5 out of 5 by from Cuts things easily It eats anything. I have had other hedge trimmers, but this one will cut anything up to an inch thick effortlessly.

Rated 5 out of 5 by from Well done! Another great product on the ak series lineup. I purchased them all, and this is another work of art. Very powerful, light, and well made. I’m very impressed with the stihl battery powered product line. Buy an extra battery so you always have one charged.

Rated 5 out of 5 by from A good trimmer The battery charges quickly and lasts a reasonable length of time. The trimmer is light and handles well. It had no problems cutting through some hedges that I've had to use a hand pruners on before. Throughout one round of trimming all the hedges and shrubs on my property, it's hard to come up with any negatives.
