STIHL RMA 443.3 Cordless Lawnmower (Shell Only)

Powerful Cordless Mowing For Larger Home Lawns

The STIHL RMA 443 Cordless Lawn Mower is designed to provide efficient mowing for medium and large gardens. Combining quiet operation with impressive battery performance, it delivers excellent results with minimal effort. Its lightweight construction and practical features make lawn care more comfortable throughout the season. Suitable for home gardeners, this mower offers dependable cutting performance while removing the inconvenience of petrol engines and power cables.

As part of the STIHL AK System, the mower is compatible with interchangeable batteries used across the range. The RMA 443 is available as either a tool only model or with a battery and charger. Two battery slots allow a spare battery to be carried onboard, reducing interruptions during larger mowing tasks.

Consistent Battery Performance

The mower features STIHL Constant Power technology, which maintains strong cutting performance throughout the entire battery charge. Unlike some cordless machines, performance does not decrease as the battery level falls. Intelligent electronics ensure the mower continues to deliver dependable power from start to finish.

The integrated Power Boost function allows the battery and mower to communicate continuously. The system automatically supplies the maximum available power when required. During lighter workloads, power output is adjusted to help protect battery life. This combination improves performance while helping extend battery runtime. The Eco mode further improves efficiency by adjusting motor speed to match mowing conditions. Lower energy consumption allows longer operating times before recharging becomes necessary.

Flexible Cutting And Excellent Results

The RMA 443 features a 41 cm cutting width, making it ideal for medium and larger home lawns. The mower can cover areas up to approximately 230 m² using the recommended battery. Its efficient design helps reduce mowing time while maintaining excellent cutting performance.

The flow-optimised blade reduces air resistance and improves energy efficiency. This allows the mower to cut larger areas while using less battery power. The mower also provides four mowing options, allowing users to collect clippings, rear discharge, side discharge, or mulch. This flexibility allows the mower to adapt to different grass conditions throughout the year.

The central cutting height adjustment offers several settings between 20 mm and 100 mm. A clear scale allows the selected height to be viewed easily. This makes it simple to achieve the desired finish across varying lawn conditions.

Comfortable Handling And Easy Storage

The mono-comfort handlebar is mounted on one side, allowing easier access to the grass collection box. This design makes removing and emptying the collector much simpler. The handlebar is also height adjustable without tools, allowing users to work comfortably.

Once mowing is complete, the handlebar folds down for compact storage and easier transportation. The practical carry handle helps lift and move the mower when required. Smooth-running wheels provide excellent traction and directional stability, improving manoeuvrability around obstacles and garden features.

Durable Construction And Efficient Collection

The 52-litre grass collection box uses airflow to maximise filling efficiency. The integrated fill-level indicator shows when the collector requires emptying. Side vents direct airflow towards the ground, helping reduce dust and debris around the operator. The mower uses a double-layer polymer deck that is lightweight, rust resistant, and highly durable. The UV-resistant construction helps protect the housing during regular outdoor use. The IPX4 splash protection rating also allows the mower to operate confidently in changing weather conditions.

Combining Constant Power technology, Power Boost performance, four mowing options, and durable construction, the STIHL RMA 443 provides excellent cordless mowing for modern home gardens.
