The Stihl FSA 45 grass trimmer/brush cutter is perfect for trimming lawn edges in smaller gardens. It is lightweight, quiet and simple to use, with a built-in Lithium-Ion battery that you plug in and charge like you would charge a phone.

The LED charge level indicator on the side of the tool shows you how much battery life is left at the touch of a button. The loop handle helps you to guide the trimmer exactly where you need it and is easily adjusted without the need for tools. The shaft is also extendable, whilst the mowing head can be turned on its side, which is particularly useful for vertical edge trimming.

The FSA 45 comes with plastic Polycut blades, which are really quick and easy to replace, without having to use any tools. They are extremely efficient and give a precise finish to the lawn. Pre-cut mowing line can also be fitted to the head but it is not included with the FSA 45 and will need to be purchased separately.

Run Times

  • Run time: Up to 20 minutes
  • Charging time: 100% in 210 minutes, 80% in 145 minutes

Please note this hedge trimmer has an integral battery, it is NOT part of the one battery fits all system (NOT compatible with the Stihl AP, AK batteries or AL chargers).

Telescopic shaft
With 8 adjustable positions along a length of 170 mm, the FSA can be optimised to match the user’s size, ensuring ergonomic working and a less tiring job – and without the need for a separate tool.

Vertical edge trimming
The mowing head can pivot through 90° for precise lawn edge trimming.

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.

Storing spare blades
The PolyCut blades can be easily replaced if worn. Up to five spare blades can be conveniently stored on the tool.

Spacer bracket
The FSA 45 has a spacer bracket for precise and efficient trimming around plants and other objects. It can be folded out or down as required.

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

  1. Andy Bird (verified owner)

    Great little strimmer. Charged from new relatively quickly. Easy to store, nice and light which my wifes likes. Easy to set up. It would have been a 5 star, but the safety key which you need to plug in the machine to use it is very small. Easy to loose and you only get one with the kit. Yes you can keep in plugged in, but then what’s the point in having it?

  2. David Barlow (verified owner)

    easy to set up and use. it only comes with the blades which i didnt realise at the time, would prefer line which i have since ordered.

  3. Andy Essex (verified owner)

    Great strimmer, very light and powerful and good quality as you would expect from Stihl, battery life around 15-20 minutes but reasonably quick charging time.

  6. Ron Moss (verified owner)

    Nice item, own and have used many Stilhl products and not disappointed with this either. Lightweight and very easy to use currently using blades which for the amount of grass that we need to strim appears to work ok. Quite quick to charge and holds for about 20 minutes before needing a recharge.
    Competitve price from Radmore & Tucker, kept informed throughout the process, ordered on a Wednesday and delivered the same Friday would thoroughly recommend.

  7. Mark Bryce (verified owner)

    Excellent piece of kit! More than enough power to go round my large front and small back garden, without a recharge.
    Blades work well, they don’t need changing every time, and don’t fall off.
    Delighted with purchase, it’s well built, and hoping it will last for many years.

  10. Julie C (verified owner)

    Delighted with this strimmer and the excellent service from Radmore and Tucker. Very easy to put together. I ordered extra blades but was a nice surprise to find there were some hooked on to the storage underneath. Plus the eye goggles were a great addition. I soaked the blades as recommended and they have done a great job. Still charge left as well. It’s great to have a strimmer that uses blades.

  11. Colin Gale (verified owner)

    Not the first item I’ve bought from Radmore & Tucker, I keep coming back, they’re a company you can trust for service, value and reliability. The Stihl cordless trimmer is exactly what I expected, performs really well, R&Ts description assisted my decision to buy this model… Thanks for great level of service from ordering to delivery… A company you can trust.

    As with others I’m very pleased with the strimmer although I’ve only used it once so far. Hopefully it will be durable and last a long time!

  13. Trish Cecile-Pritchard (verified owner)

    What a great lightweight strimmer, wish I’d ordered one sooner!
    Easy to put together and use.
    20 minutes battery use enough to do my edging around lawns and beds.
    The blades work well and unlike cord strimmers don’t leave broken bits for the dog to find to chew on….
