STIHL RMA 243 Cordless Lawn Mower (Tool Only) – 41cm

The STIHL RMA 243 cordless lawn mower (tool only) is a lightweight, quiet battery-powered push mower built for small to medium-sized home gardens. As part of STIHL’s AK System, it delivers clean, low-noise mowing with the convenience of interchangeable batteries across the AK range.

Please note: This listing is the tool-only version (no battery or charger). This model is also available as a set with a battery and charger—please make sure you select the correct option before adding to basket.

Built with a durable sheet steel deck, the RMA 243 features a 41cm (16") cutting width and single-point cutting height adjustment from 20mm to 100mm, making it easy to adapt to seasonal growth and your preferred finish.

The RMA 243 is powered by an AK 20 battery (recommended) and includes two battery slots in the powerhead, allowing you to carry a second AK battery and switch over quickly when the first runs out. With the recommended AK 20 battery, you can mow lawns up to 230 m² on a full charge (working area varies depending on grass conditions and cutting height).

With its flexible 4-in-1 mowing system, you can choose the best method for your lawn and conditions: collect, cut and drop, side discharge, or mulch using the multi-blade and mulching attachment. The 52-litre grass catcher box features a fill-level indicator and is designed for fast, clean emptying.

Comfort is enhanced by the mono-handlebar, which makes it easier to remove the catcher and provides straightforward, ergonomic control. The handlebar is height adjustable and foldable for compact storage after use, and includes a 10-year domestic warranty.
