Description
The STIHL RMA 448.3 V Cordless Lawn Mower is designed for homeowners looking for the performance of a petrol mower with the convenience of battery power. Ideal for medium to large gardens, this advanced cordless mower combines powerful cutting performance, variable speed self-propelled drive and versatile mowing functions to deliver professional-quality results with low noise, zero direct emissions and minimal maintenance. As part of the STIHL AK Battery System, it offers excellent compatibility with a wide range of cordless garden tools.
Powered by the STIHL AK Battery System, the RMA 448.3 V provides reliable cordless performance for everyday lawn care. The recommended AK 30 S battery delivers enough runtime to mow areas up to approximately 340m² on a single charge. The mower also features two battery slots, allowing you to carry a spare battery and switch over quickly when the first battery is depleted, helping you complete larger mowing tasks with minimal interruption.
Tool only. Battery and charger sold separately.
The robust 46cm polymer cutting deck offers the ideal balance between productivity and manoeuvrability. Lightweight yet exceptionally durable, the deck is resistant to rust, UV damage and impacts, making it suitable for years of reliable use. Its double-layer construction adds further strength while keeping the overall weight low for easier handling around trees, flower beds and garden features.
One of the standout features of the RMA 448.3 V is STIHL’s Vario wheel drive. The variable speed drive can be adjusted between 2.0km/h and 4.5km/h, allowing you to match the mower’s pace to your own walking speed and the mowing conditions. Whether carefully manoeuvring around borders or covering larger open lawns, the adjustable drive system provides greater comfort, improved control and reduced operator fatigue.
The mower offers four versatile mowing functions to suit different lawn conditions throughout the year. You can collect grass clippings using the supplied grass catcher box, discharge clippings from the rear by removing the collector, use the integrated side discharge chute for longer grass or activate the integrated mulching function to finely chop clippings and return them to the lawn as a natural fertiliser. This flexibility allows you to adapt the mower to changing conditions without the need for additional tools.
The spacious 52-litre grass collection box has been designed to maximise airflow, ensuring efficient collection and fewer emptying stops. A practical fill-level indicator lets you know when the collector is full, while the ergonomic design allows the box to be removed, emptied and refitted quickly and easily. The mono-comfort handlebar provides unrestricted access to the collector, making emptying even more convenient.
Central cutting height adjustment allows you to choose from seven cutting heights between 20mm and 100mm using a single lever. This makes it easy to achieve the perfect finish whether maintaining a closely cut summer lawn or leaving the grass slightly longer during drier periods. The mower also benefits from STIHL’s Power Boost technology, which automatically increases performance when heavier cutting conditions are detected, while Constant Power technology maintains consistent cutting performance as the battery charge decreases. The IPX4 rating provides splash protection, allowing the mower to be used confidently in damp conditions.
Designed with operator comfort in mind, the height-adjustable mono-comfort handlebar provides an ergonomic working position while folding down quickly for compact storage. Smooth-running double ball-bearing wheels improve manoeuvrability and traction across a variety of lawn surfaces, while the lightweight construction makes the mower easy to transport and store between uses.
The STIHL RMA 448.3 V Cordless Lawn Mower is the ideal choice for homeowners looking for a premium battery-powered self-propelled mower that combines performance, versatility and ease of use. Featuring a durable 46cm polymer cutting deck, Vario wheel drive, four mowing functions, a 52-litre grass collector and compatibility with the STIHL AK Battery System, the STIHL RMA 448.3 V delivers efficient, quiet and professional-quality mowing for medium to large gardens.
