HSA 45

HSA 45
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.

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.

Rated 5 out of 5 by from Light Weight ( Great ) I have a lot of bushes to trim. My HSA 45 will trim them in half the time my gas powered Stihl would. This is the greatest battery powered tool I have ever purchased. Well worth the cost!

Rated 5 out of 5 by from This product is lightweight and easy to use I just purchased the HSA 45 hedge trimmer and was very pleased with the first time I used it last week. Has great safety controls and I trimmed all my hedges in less time than with my electric trimmer.

Rated 4 out of 5 by from Nice little trimmer....not too dependable I got this hedge trimmer for Mother's Day 2018 to primarily be used for trimming vines (mostly honeysuckle) on about 500' of chain link fence. In my experience a fully charged battery lasts about 30 minutes with constant use. It is lightweight and easy to operate. So far, so good. The issue I had was, even after spraying the blades with Stihl resin remover/lube as instructed by the salesman, if the trimmer was idle for a few weeks the motor would not engage the blades. It seemed to be stuck. I returned the trimmer to the dealer and was given a replacement. The next time this happened I left it at the dealership for two weeks to see if they could fix the problem. They could not, and I was given another replacement. I did not use the trimmer during the winter months and when I tried to use it just last week I again had the same issue.

Rated 5 out of 5 by from A Good Piece of Equipment This is just what the doctor ordered for our yard work. It made quick work of trimming the bushes and shrubs and is easy to start and use. Those are the two qualities that make all the difference in the world for me.
