HSA 56
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.

Rated 5 out of 5 by from This is a great product; has served me well the HSA hedge trimmer is well built, dependable and has ample power for projects around the house. We use it for trimming hedges, flowers and clipping grass areas in places to narrow for the lawn mower.

Rated 5 out of 5 by from HSA 56 portable hedge trim without dragging electric cords. Best feature is the run time. We can usually complete trimming all bushes on our 1 acre yard before recharging. Recharge is fast also. It is also powerful and easily cuts 1/4” or bigger bush branches, and trims large garden grass specimens without choking. For me it is light enough to use and make our bushes look great whether square or round trim design.Maintenance consists of cleaning and lubricating the cutter bar before each use.Stihl quality for sure. I also own a Stihl chain saw and small plant trimmers.

Rated 3 out of 5 by from Failed after first season Last summer I bought the HSA 56 and used it several times over that summer. I was impressed with the power, runtime, and ease of use. I oiled the blades, removed the battery and hung it up in the garage until this summer. When I went to use it this summer the blades would not move, there was just a “click”. The great thing about Stihl products is the dealer network. I took it to where it was purchased and had it repaired free of charge. The good thing is Stihl backs its products, the bad thing it failed in less than one year. I recommend this product with reservations.

Rated 5 out of 5 by from Awesome tool Power to spare. I trimmed every bush in the yard and just used on bar of the battery life.

Rated 5 out of 5 by from Excellent Medium Duty Trimmer This is a great trimmer for medium duty jobs. It is very light, runs long and well on the AK 30 battery and is made with the usual quality that Stihl brings to all of their products. I highly recommend it for medium size yards and medium trimming tasks.
