What is the STIHL RMA 243?
The STIHL RMA 243 is a cordless push-along lawn mower designed for homeowners maintaining small to medium-sized gardens. Part of STIHL’s 2 Series battery range, it uses the AK System, meaning the battery you buy for this mower works across your other STIHL AK tools too.
Available at Cardiff Lawn & Garden as tool only (Part No. WA200111400) or as a kit with the AK 20 battery and AL 101 charger.

Who is this mower for?
The RMA 243 is ideal for homeowners with lawns up to 300 m² who want a quiet, low-maintenance alternative to petrol. If you already own STIHL AK tools such as a cordless strimmer, hedgetrimmer or blower, your existing batteries will work straight away.
Commonly asked: Can I use the STIHL RMA 243 in wet conditions? Yes. It carries an IPX4 rating, which means it is protected against splashwater from all directions and is built for Welsh weather.
4 Ways to Mow
The RMA 243 gives you full flexibility depending on what your lawn needs:
Cut and Collect uses the 52-litre grass catcher box with fill-level indicator for a clean finish. Cut and Drop removes the box and lets clippings fall for natural mulching. Side Discharge uses the built-in flap to direct cuttings to the side. Mulch fits the multi-blade and mulching attachment to return fine clippings directly to the soil.
No additional tools are required to switch between modes.
Why the RMA 243 performs consistently
STIHL’s Constant Power technology means the mower maintains full performance throughout the battery charge, unlike most cordless tools that gradually lose power as the battery drains. The energy-efficient, flow-optimised blade design also means you cover more ground per charge.
The AK 20 battery covers up to 230 m². Step up to the AK 30 or AK 30 S and you get up to 300 m² per charge.
Built to last, easy to store
The housing is made from torsion-resistant sheet steel, giving heavy-duty construction in a domestic mower. The mono-comfort handlebar folds flat for compact storage in a shed or garage and adjusts to your preferred mowing height without any tools.
