Stihl FSA 45 Cordless Grass Trimmer
The Stihl FSA 45 is a lightweight cordless grass trimmer designed for small gardens and routine trimming jobs around the home. With an integrated battery and compact design, it's a convenient option for keeping lawn edges, borders and hard-to-reach areas neat without the noise, maintenance or starting hassle of a petrol machine.
Weighing just 2.3kg, the FSA 45 is easy to handle and comfortable to use for longer periods. The adjustable shaft and loop handle can be altered without tools, while the mowing head angle can be adjusted for edging work along paths, driveways and flower beds. The spacer bracket also helps protect plants, trees and garden features when trimming close to delicate areas.
The FSA 45 comes fitted with the Stihl PolyCut cutting system and allows quick switching between polymer blades and mowing line depending on the task. An integrated battery with charge level indicator keeps everything self-contained, making it an ideal choice for homeowners looking for a simple, grab-and-go garden tool.
For small gardens, the Stihl FSA45 is an excellent choice. It is lightweight and is probably a contender for the easiest to use strimmer on the market. If you need something with a longer runtime than 20 minutes though, we recommend looking to EGO strimmers for a high quality machine that will last longer and is more suited to tougher jobs.
