What’s Included? 

  • Stihl HSA 45 Cordless Hedge Trimmer Complete with Integrated Battery and Charger

Compact and ergonomic
The integrated battery cells mean that the tool is optimally balanced. The HSA is easy to handle. Its streamlined design creates plenty of room for manoeuvre.

Soft handle
Thanks to the two-hand control device and soft handle with lever lock function and lever, the user always has the cordless hedge trimmer safely under control.

Tip protector with hanging eye
The tip protector protects the tip of the cutter bar against damage when working close to walls and the ground. The hedge trimmer tip protector is fitted with an integrated hanging eye for wall mounting.

Charge level indicator
The remaining working or charging time can be viewed at any time by pressing the button. Four LEDs light up, or flash green or red, to indicate the charging state or problems.

Activation key
The tool can only be used with the activation key. If the key is removed, the tool switches off to guard against unintentional activation. The tool can be safely stored and transported.

Charger cable
The STIHL HSA 45 draws its power from an integrated 18V lithium-ion battery. The battery is easily charged using the charger cable.

Quiet technology
The STIHL cordless tools are so quiet you don’t even need to wear ear protection.

Pruning system
The single-sided precision-ground and double-sided cutting blades produce a very clean cut when trimming hedges. The 33° cutting angle delivers excellent cutting performance. The blade teeth geometry allows cutting of twigs up to 8 mm thick.

    Great item and customer service was fantastic. All round excellent purchase!

  2. Mr John du Heaume (verified owner)

    Excellent cordless hedge trimmer, light and easy to use, cuts cleanly, already have a Stihl petrol hedge trimmer for major work but it’s quite heavy, this is perfect for odd bits, no hassle of dragging electric flex around. Would buy again. Cheers John.

  3. Adrian Bond (verified owner)

    Very pleased with the product it’s easy to use and ideal for small to medium hedging jobs. The item was well priced and was delivered quickly so could not ask for more. I would certainly use Radmore & Tucker again.

    What a fantastic Hedge Trimmer this machine exceeds all my expectations. so light, quiet, and cuts like a dream.
    Radmore & Tucker, What a very well organised company even in this difficult time their service was first class
    Very quick delivery a week sooner than quoted a purchase from this company would be a very wise choice.

  8. John Percy (verified owner)

    Very helpful customer services at R&T.

    Stihl HSA45 quick to charge up, much lighter to handle than my petrol hedge trimmers, did a really good job on sixty yards of hornbeam hedge with plenty of charge left.

  9. Katrina (verified owner)

    Really perfect for me as it’s lightweight and goes through all my big privet hedge and more….since I’ve had a shoulder operation it’s just really nice to be able to cut the hedge again. Excellent company and service

  10. Keith Brown (verified owner)

    An excellent light weight hedge trimmer which is more than adequate for its purpose. As ever the service from Radmore and Tucker was also excellent.

  11. Steven Care

    Brilliant bit of kit, light weight to use.
    Tried it today and at first thought it wouldn’t cope. Surprisingly up to the job. Have had the petrol versions before, so now want to see is upto the same tasks.
    Easy to charge.

  15. Bart Borchardt (verified owner)

    Outstanding service from R&T and this is a fantastic bit of kit. Lightweight (you’ll be grateful!), good battery life and v easy to use. I would recommend this & the excellent R& T 100%. No need to shop around!

  16. ANDREW OXLEY (verified owner)

    Wow a Stihl product for a great price and free delivery!
    Feels good, quality as you would expect, great to use, I stopped using petrol items due to weight and love the freedom of cordless and the light weight. I was concerned about the various safety features as sometimes they can be very fiddly but on this machine they fall straight to hand so no naughty bodges required lol.

  17. John Higgie (verified owner)

    Very useful hedge trimmer, light weight an advantage, we use the petrol hedge cutter much less since we got this Stihl trimmer.

  18. Pam Bradshaw (verified owner)

    Tried out this hedge trimmer on one of my upright yew trees…. it was so easy and light to handle. Made a neat job. Very pleased with the result. Particularly like the safety end cap. Already had a Stihl strimmer, of the same specification, and this was the reason I chose this hedge cutter. Highly recommended.

  19. Paul Byrne (verified owner)

    Radmore & Tucker held back delivery at my request and were very efficient. Hedge trimmer very light and has produced excellent result.

  20. Jeremy H (verified owner)

    Excellent service as always. Haven’t tried the product yet as a Christmas present. I expect not to be disappointed with the quality and performance of my Stihl hedgecutter

  21. Sarah Hemsley (verified owner)

    Perfect and light. Long lasting battery time. Gives a nice straight cut. Very quick delivery.
    Many thanks, Sarah.

  22. Ethel (verified owner)

    Tried for first time today very light and easy to use . Very impressed

  23. john stevenson (verified owner)

    Lightweight product ideal for shaping ornamental shrubs eg. Box ( Buxus Sempervirens) or small compact Privet hedges. After using petrol you may find quietness needs getting used to.

  24. Edward (verified owner)

    Very good value for money lightweight cordless hedge trimmer. It lasts a reasonable time (c 45 min) and cuts light growth cleanly. It’s particularly suited to small or awkward jobs where its lightness and manoeuvrability are helpful. But it does run slower and is less powerful than my long handled petrol trimmer, which I still need for the stronger vertical growth on the top of the hedges.

  25. kevin garner (verified owner)

    Great product.
    Lightweight and made easy work of our privet.
    Easy to order on line and the delivery was prompt.
