The STIHL RMA 248 cordless lawn mower is a substantial 46 cm / 18-inch battery mower designed for small to medium-sized domestic lawns. Its wide steel cutting deck covers open areas efficiently, while cordless operation removes the cable, fuel and starting routine associated with corded and petrol mowers.
The RMA 248 is a hand-propelled push mower and forms part of STIHL’s 36 V AK System. It can collect, cut and drop, side-discharge or mulch the grass, giving you more flexibility than a conventional collection-only mower.
Choose the tool-only RMA 248 if you already own suitable STIHL AK batteries, or select the complete kit with an AK 20 battery and AL 101 charger.

Who is the STIHL RMA 248 best suited to?
The RMA 248 is a good choice for customers who want the convenience of battery power but prefer the solid construction and wider deck of a traditional steel-bodied lawn mower.
It is particularly suitable for:
- Small to medium-sized lawns of up to approximately 220 m² with the recommended AK 20 battery
- Flatter gardens where a push mower is comfortable to use
- Open lawns where a 46 cm deck can reduce the number of passes required
- Customers replacing a corded electric or compact petrol mower
- Existing owners of STIHL AK batteries and chargers
- Users who want collection, mulching and side-discharge options in one machine
Because the RMA 248 weighs approximately 27 kg without its battery and does not have powered wheel drive, the STIHL RMA 248 T self-propelled mower may be preferable for sloping lawns or users who want drive assistance.
Four different ways to mow
The STIHL RMA 248 provides four mowing methods, allowing you to adapt the mower to the grass conditions and how you want to manage the clippings.
- Cut and collect: collect clippings in the 52-litre grass box for a tidy finish.
- Cut and drop: remove the grass box and allow the clippings to fall behind the mower.
- Side discharge: use the integrated side-discharge flap when mowing longer grass or when collection is unnecessary.
- Mulching: use the multi-blade and mulching attachment to finely cut and return the clippings to the lawn.
No additional tools are normally required when changing between the four mowing methods, although you should always follow the operating instructions supplied with the mower.
Battery performance and lawn coverage
The RMA 248 is part of the STIHL AK System. Compatible AK batteries can also be used in a wide selection of STIHL grass trimmers, hedge trimmers, blowers, chainsaws and other domestic garden tools.
| STIHL battery | Manufacturer-estimated area per charge |
|---|---|
| AK 10 | Up to 110 m² |
| AK 20 – recommended | Up to 220 m² |
| AK 30 S | Up to 285 m² |
Actual coverage varies with grass length, moisture, cutting height, terrain, battery condition and mowing technique.
There are two battery slots in the mower. One battery powers the machine while a second charged battery can be carried in the spare slot. When the first battery is depleted, the user manually switches to the second battery; the mower does not change between batteries automatically.
Power Boost and Constant Power
STIHL’s intelligent electronics allow the mower and compatible battery to communicate with each other. Power Boost makes the available battery power accessible when cutting conditions require it, while Constant Power helps maintain consistent cutting performance as the battery charge reduces.
A flow-optimised blade is designed to minimise unnecessary air resistance and use the battery’s available energy efficiently.
Wide 46 cm steel deck
The 46 cm / 18-inch cutting width allows the RMA 248 to cover wider areas efficiently. This makes it particularly useful on open domestic lawns where a narrower mower would require more passes.
The torsion-resistant sheet-steel housing gives the mower a robust, durable construction. Smooth-running wheels help maintain directional stability and make the mower easier to manoeuvre around borders, trees and other garden features.
20–100 mm central cutting-height adjustment
The cutting height can be adjusted centrally between 20 and 100 mm. A single control changes the height across the mower rather than requiring each wheel to be adjusted independently.
Use a higher setting when cutting longer grass, uneven ground or the first growth of the season. The height can then be reduced gradually over later cuts to avoid removing too much grass at once.
52-litre folding grass collection box
The RMA 248 has a 52-litre folding grass box with a fill-level indicator. The airflow is designed to fill the box efficiently, while the folding construction allows the collected grass to be emptied more easily.
The comfort mono-handlebar is mounted on one side of the mower, leaving clearer access when removing and replacing the collection box.
Comfortable handling and compact storage
The comfort mono-handlebar can be adjusted to suit the user’s height without tools. It can also be folded down for storage or transport, helping the mower fit more easily into a shed, garage or vehicle.
An integrated carrying handle helps when repositioning or transporting the mower. Customers should nevertheless be aware that the mower weighs approximately 27 kg before the battery is installed.

Masseys recommendation
The RMA 248 is a strong option for customers who want a wide, durable cordless mower but do not require self-propelled drive. Its 46 cm steel deck makes it efficient on open lawns, while the four mowing methods provide considerably more flexibility than a collection-only mower.
We would recommend considering the RMA 248 T instead if your lawn has notable slopes, the ground is difficult, or you would find pushing a mower weighing more than 27 kg uncomfortable.
