The RMA 239 C is the ideal lawn mower for small to medium-sized lawns.

It is quiet and manoeuvrable so you can navigate your flower beds, patios and garden furniture with ease, and the central cutting-height adjustment makes it simple to cut your grass to the length you want. Our unique mono-handle design is sturdy but has many benefits - it can be easily adjusted to suit your height, it folds over for easy storage in one simple movement and, best of all, it gives you easy access to the grass catcher box when you need to empty it.

The flow-optimised blades maximise the battery life on your RMA 239 C and it is so easy to use too - just pop in the battery, switch it on and get mowing!

  • Area covered using recommended AK 20 battery: 250m²


Height-adjustable, mono-handle design

The unique design of the mono-comfort handlebar on the RMA 239 C means that the handle can be simply adjusted to suit your height or folded over completely with one press of the lever. It also gives you clear access to the grass catcher box - there's no need to pass it between the handles, just lift it straight off in one movement.

Carrying handles

A carrying handle has been built into the body of the mower to make it easy for you to transport it.

Innovative grass catcher box

The grass catcher box is made of a sturdy plastic, and is easy to empty through the clam-shell opening - simply hold the box over the bin or compost heap using the handles on both sides and pull it open. The box also has vents on all sides that face downward so you won't get covered in dirt and dust when mowing.

Flow-optimised blades

All STIHL lawn mowers have a flow-optimised blade to lift and neatly cut the grass, without using unnecessary battery power.

Central cutting height adjustment

It's easy to adjust the cutting height of the mower in one quick movement with the spring loaded lever. There are five different heights to choose from between 20 and 70mm.

Polymer housing

The housings of the STIHL battery-powered lawn mowers are made of a high-quality polymer material. This extremely lightweight polymer housing combines high resistance and robustness against forces, heat and UV radiation.

Easy-running wheels

The hard-wearing wheels on the RMA 239 C have traction and tread patterns that are designed to make it easy for you to move the mower around your flower beds, trees and other obstacles in the garden.

Clever design for maximum airflow

The airflow produced by the blades channels the clippings directly into the grass catcher box to make sure it fills right to the top. The grass level indicator on the top of the box then drops down so you know exactly when to empty it.


QWhat size garden will it maintain?

With an AK 20 battery, the RMA 239 C lawn mower will cut approximately 250m² of lawn.

QHow long does it take to charge?

To fully charge an AK 20 battery with an AL 101 charger, it takes 180 minutes, but you can charge it up to 80% in 135 minutes.

QWhat battery does it use?

The mower is powered by an interchangeable 36V Lithium-Ion battery.

QAre the batteries interchangeable?

Yes, all of the tools in the AK Cordless System use the same style of battery. There are three different batteries in the range, which all have different capacities. For the RMA 239 C, we recommend the AK 20 battery, but you can also use the higher capacity AK 30 battery in this tool. We don't recommend using the AK 10 as the RMA 239 C won't run for as long with this smaller battery and you will need to charge it more often.

QWhat should I wear when using this mower?

We recommend that you wear sturdy boots or shoes and snug-fitting clothes.

QHow big is the grass catcher box?

The RMA 239 C has a 40 litre grass catcher box.

QWhat is the cutting width of the RMA 239 C?

It has a cutting width of 37cm.


#1Cleaning your RMA 239 C

#2Storing your RMA 239 C

Store your RMA 239 C in a clean and dry area away from children at all times.

#3Looking after your battery

#4Check for wildlife

Don’t forget to check your work area for wildlife before starting to use your tool. In particular, you should check for nesting birds before trimming hedges, as well as checking for other small animals such as hedgehogs before trimming long grass.
