The RMA 253.3 T is ideal for homeowners with small to medium-sized lawns, typically up to around 325m². Its single-speed self-propelled drive makes it particularly good for gardens with gentle slopes or for users who prefer not to push a mower, reducing fatigue during use.
This is a ‘Tool Only’ model, so the battery and charger are sold separately. It is part of the STIHL AK System. For the best performance and maximum mowing area, the AK 30 S battery is recommended, but it is also fully compatible with the AK 10 and AK 20 batteries if you already own them from other AK tools.
This mower is highly versatile, offering four functions. You can use the standard collection with the 55-litre grass box, rear discharge (cut and drop) by removing the box, side discharge using the integrated flap, or mulching with the included multi-blade to naturally fertilise your lawn.
No, storage is made simple thanks to the innovative mono-handlebar. It can be folded forward quickly and without tools, making the mower significantly more compact for easy storage in a shed or garage, saving valuable space.
