The STIHL FSA 50 is an exceptionally quiet, battery-powered grass trimmer designed specifically for domestic mowing and lawn edging. As part of the STIHL AK System, it offers the convenience of cordless operation without the need for ear protection, making it ideal for use in noise-sensitive residential areas.
Its well-balanced, lightweight design makes it accessible for operators of all abilities. The trimmer features a telescopic shaft and an adjustable loop handle—both of which can be repositioned without tools—to ensure a comfortable working posture regardless of the user's height.
90° Rotating Head: The mowing head can be rotated 90 degrees, instantly converting the tool into a precision lawn edger.
Multi-Angle Adjustment: The head can be set at three different angles to facilitate trimming in awkward spaces, such as under garden benches or along slopes.
AutoCut C 3-2 Mowing Head: This "bump-feed" head can be refilled with line without using tools. Simply tap the head on the ground during use to automatically extend the mowing line.
Spacer Bracket: A metal guard protects trees, flowerbeds, and fragile objects from the cutting line. It can be folded up when not required for open-area mowing.
Variable Speed Trigger: Allows the operator to control the RPM of the mowing head, helping to conserve battery life during lighter trimming tasks.
Neutral Locking Position: A two-stage battery slot allows the battery to be secured in the tool for transport without engaging the electrical contacts, preventing accidental starts.
AK System Compatibility: Recommended for use with the AK 10 battery, providing a perfectly balanced feel and up to 25 minutes of runtime.
Voltage: 36V (STIHL AK System)
Cutting Diameter: 280 mm
Cutting Tool: AutoCut C 3-2 (nylon line)
Total Length: 116 cm (min) / 147 cm (max)
Weight: 2.3 kg (excluding battery)
Vibration Level: 2.0 m/s² (left/right)
Sound Pressure Level: 76 dB(A)
Tool-Free Adjustments: Quickly customize the handle and shaft length to suit your height.
Quiet Technology: Operates at low decibels, removing the need for bulky ear defenders.
Ease of Use: Simple "plug and play" battery operation with a clear LED charge indicator on the battery.
Compact Storage: The adjustable shaft allows the tool to be shortened for easy storage in small sheds or garages.
Precise Control: The variable speed trigger puts the operator in total command of the cutting power.
Q: IS THIS GRASS TRIMMER SUITABLE FOR TRIMMING THROUGH WEEDS OR SCRUB?
A: No, the AutoCut mowing head on the FSA 50 is only suitable for trimming grass, along lawn edges or in small areas of lawn. If you need to cut thicker, woody material, a brushcutter with a grass cutting blade or brush knife may be more suitable. You can find out more information about the different cutting attachments we have available on the STIHL Blog. Please visit your nearest STIHL dealer, who will be able to give you expert advice and talk you through our full range of brushcutters and cutting tools.
Q: WHAT TYPE OF CUTTING ATTACHMENT DOES THIS USE?
A: The FSA 50 uses an AutoCut C3-2 mowing head, which you can buy replacement line for. It can also be used with the PolyCut 3-2 too (sold separately).
Q: HOW LONG DOES THE BATTERY LAST?
A: The AK 10 battery will last up to 25 minutes or mow up to 500m of lawn edges, depending on the type of grass that is being cut and how the tool is being used.
Q: HOW LONG DOES IT TAKE TO CHARGE?
A: To fully charge the battery it takes 80 minutes, or to charge it up to 80%, it takes 55 minutes.
Q: WHAT SIZE GARDEN WILL IT MAINTAIN?
A: The FSA 50 is the ideal grass trimmer for medium to large gardens.
Q: WHAT BATTERY DOES IT USE?
A: The tool is powered by an interchangeable 36V Lithium-Ion battery.
Q: ARE THE BATTERIES INTERCHANGEABLE?
A: Yes, all of the tools in the AK Cordless System use the same style of battery. There are three different batteries in the range, which all have different capacities. For the FSA 50, we recommend the smaller capacity AK 10 battery as it is lighter and means the tool is perfectly balanced, but you can use the AK 20 and AK 30 battery in this tool.
