A hedge trimmer with a built-in battery, combining excellent cutting performance and affordable price.

Product Description

Part of the AI Series, the HSA 45 hedge trimmer delivers high cutting speeds and a compact, ergonomic design. It is lightweight for enhanced portability and features an integrated battery – so no separate battery or charger to manage. On a single charge, the HSA 45 can trim a hedge 20" wide and a length longer than a football field (360 feet). And with its high cutting speeds of 2,500 strokes per minute, it will take care of your small, urban yard in no time. It’s a great battery-powered hedge trimmer for smaller property care.

Usage claim tested and verified by an independent third-party test laboratory. Run time may vary based on battery type, charge level and capacity, model, operating style and conditions.

HSA 45 is rated 4.6 out of 5 by 38.
Rated 5 out of 5 by from Great tool for small jobs. It works well for small shrubs, flower beds and tall grass. Battery life is about 30 minutes. Good product.

Rated 1 out of 5 by from Not charging Purchesd yesterday plugged it in to charge it over night will not charge at all. Going to have to return it before ever using it. Makes you wonder about quality control. Have a still chainsaw several years old still works great, but wondering if I made right choice. Told my wife stihl makes a good product not so sure now. She was going to use it Monday but not this one.

Rated 5 out of 5 by from worked better than expected Like all my Stihl products, this one is excellent. I got it for my wife since she likes to trim hedges to suit her (she doesn't like my trimming). I focused on light weight, no engine to start, and no extension cord to accidently cut (as she has done). I was worried about it being too slow and not tough enough. My fears were unfounded. This integral battery model works great for her, and I like it too.

Rated 5 out of 5 by from Excellent product I've been using your HSA 45 for more than a year. We have a 1 acre yard with LOTS of cutting jobs. Excellent piece of equipment! Light weight, maneuverable, cuts well, very easy to use. Battery life is great, lasting through majority of trimming chores. I would highly recommend this product to anyone. 5 stars.

Rated 3 out of 5 by from Hard to maintain. I have only used this product 2 or 3 times. Blades sticking together after every use. I have used the Stihl cleaner/lubricant generously and it seems to make it worse. I didn’t use the cleaner after the last use and the blades didn’t lock up. I’ll try not using the lubricant and see what happens. You should not have to remove the blade screws and clean it after every use.I work for Beard Equipment in Mobile AL,who is a Stihl dealer.Thank you.

Rated 5 out of 5 by from Lightweight and Powerful I bought the hedge trimmer because it was so light. I didn't expect it to perform as well as it does. I recommend this trimmer for routine homeowner landscaping.

Rated 5 out of 5 by from Very Happy with purchase I have been buying Stihl products for 25 years and have never been disappointed. My recent purchase of a new set of hedge trimmers did not disappoint. I know when I purchase a product from Stihl I am getting a high quality product. I will be purchasing a pressure washer before the end of the week. Really cannot say enough about my experience with Stihl.
