Efficient Cordless Mowing for Home Gardeners
The STIHL RMA 248.3 is a battery-powered push lawn mower designed specifically for homeowners seeking an efficient and easy-to-use solution for small to medium-sized lawns. As part of the versatile STIHL AK System, this mower combines quiet, cordless freedom with robust construction. This is a ‘Tool Only’ version, allowing you to use your existing AK system batteries and charger.
Versatile 4-in-1 Mowing System
This lawn mower offers exceptional flexibility with four different mowing options, requiring no additional tools to switch between them. You can choose to cut and collect with the 52-litre grass catcher box, cut and drop by removing the box, use the integrated side discharge flap, or mulch the clippings finely back into the lawn using the multi-blade and mulching attachment. This versatility ensures you can adapt to different lawn conditions and preferences throughout the season.
User-Friendly Design and Durable Construction
Engineered for comfort and longevity, the RMA 248.3 features a sturdy, torsion-resistant sheet steel deck. The innovative mono-comfort handlebar is height-adjustable for ergonomic operation and folds for compact storage. This design also provides unrestricted access to the grass catcher box, which includes a fill-level indicator to let you know precisely when it’s time to empty. Smooth-running wheels provide excellent traction and manoeuvrability, making lawn maintenance a straightforward task.
Advanced STIHL Battery Technology
The RMA 248.3 is equipped with intelligent electronics that ensure constant power output, regardless of the battery’s charge level. The powerhead features two battery slots, so when one battery is depleted, you can quickly switch to the second and continue mowing. Its flow-optimised blades operate with minimal air resistance, maximising the energy from the battery for longer runtimes. The mower’s performance varies based on the AK battery used, making it a flexible part of your garden tool collection.
