STIHL RMA 243.3 Cordless Lawn Mower (Shell Only) (WA200111400)

Efficient Cordless Mowing for Home Gardens

The STIHL RMA 243 Cordless Lawn Mower provides quiet, straightforward mowing for small and medium-sized domestic lawns. Its 41cm cutting width balances efficient coverage with easy manoeuvrability around typical garden features and narrower areas.

The mower belongs to STIHL’s AK System, providing battery compatibility with other suitable tools across the range. With the recommended AK 20 battery, it can mow lawns measuring up to 230m² per charge.

Four Flexible Mowing Options

The RMA 243 provides four different mowing methods, allowing users to adapt their approach to changing lawn conditions. It supports collection, cut-and-drop mowing, side discharge and mulching without requiring additional tools.

An integrated side-discharge flap provides convenient grass dispersal when collection is unnecessary. The multi-blade and mulching attachment finely process clippings when users prefer returning material directly onto their lawn.

Durable Deck and Adjustable Cutting Height

A robust sheet steel deck provides excellent durability for regular domestic lawn maintenance. Its torsion-resistant construction creates a strong housing designed to provide dependable service throughout repeated mowing seasons.

The central cutting-height adjustment offers settings between 20mm and 100mm, providing flexibility for different lawn conditions. A clear scale displays the selected setting, making accurate height adjustment simple before mowing.

Intelligent and Consistent Battery Performance

STIHL’s CONSTANT POWER technology maintains consistently high performance instead of gradually reducing output as the battery charge decreases. This helps the mower deliver dependable cutting performance throughout the available battery charge.

Compatible equipment also benefits from POWER BOOST, allowing intelligent communication between the machine and suitable battery. The system provides maximum available power when required while temporarily adjusting output during particularly intensive operation.

Two battery slots allow users to carry two AK batteries within the mower during operation. When one battery becomes depleted, users can quickly switch to the second and continue mowing.

Comfortable Handling and Efficient Collection

The height-adjustable mono-comfort handlebar provides an ergonomic working position while improving access to the grass collector. Its single-sided design makes removing the collector easier, while tool-free adjustment accommodates different user heights.

A generous 52-litre folding grass collection box provides excellent capacity while remaining straightforward to empty. Its fill-level indicator shows when emptying is required, helping prevent unnecessary interruptions during mowing.

The flow-optimised blade reduces air resistance, helping the mower use stored battery energy more efficiently. This energy-conscious design supports greater mowing coverage from the available battery capacity.

Practical Design for Everyday Mowing

Durable smooth-running wheels provide traction and directional stability, supporting controlled manoeuvring throughout regular lawn maintenance. A practical carry handle also makes transporting the mower between storage and working areas considerably easier.

The foldable handlebar reduces the mower’s overall storage footprint when work is complete. Its IPX4 splashwater protection also provides protection against splashwater from all directions.

The RMA 243 is available tool only or as a set with battery and charger. Customers should select their preferred configuration carefully before adding the mower to their basket.
