The RMA 443 C is a powerful and manoeuvrable cordless lawn mower, which is ideal for larger areas of lawn.

It has an eco mode that can be switched on so that the speed of the lawn mower automatically adapts to the mowing conditions to preserve the battery life where possible.

The RMA 443 C is so simple to use and, with the innovative mono-comfort handlebar, it is also easy to access and empty the grass catcher box. The sturdy polymer housing is robust but is also lightweight making it easy to move and transport the mower - this is made even easier by the built-in carrying handles.

As with all STIHL lawn mowers, the blades have been designed to create the perfect airflow, which lifts the grass, cuts it neatly and pushes it into the grass catcher box with minimal resistance, so it also makes the most of the battery life. 

The RMA 443 C is part of our AP System range of tools and uses AP interchangeable batteries - it is not compatible with the AK batteries in the AK System.

  • Area covered with recommended AP 200 battery: Up to 360m²

QWhat size garden will it maintain?

A: With the recommended AP 200 battery, the RMA 443 C lawn mower will cut approximately 360m² of lawn.

QHow long does it take to charge?

A: To fully charge an AP 200 battery with an AL 101 charger, it takes 200 minutes, but you can charge it up to 80% in 150 minutes.

QWhat battery does it use?

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

QAre the batteries interchangeable?

A: Yes, they are interchangeable with other tools in the AP System range that use the AP batteries. They are not interchangeable with the AK System tools.

QWhat should I wear when using this mower?

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

QHow big is the grass catcher box?

A: The RMA 443 C has a 55 litre grass catcher box.

QWill the blade need sharpening?

A: Keeping the blade sharp will give you a precise finish on your lawn. If you notice that the tips of the grass look torn after mowing and the cut isn't as neat, the blade may need sharpening. Our approved STIHL dealers can do this for you - find your nearest dealer

A: The RMA 443 C has a cutting width of 41cm.

QHow do I know when the grass box is full?

A: The grass catcher box has a handy grass level indicator on the top - when the white indicator drops down, the box is full and should be emptied.

QCan I use this lawn mower on wet grass?

A: Yes, you can - STIHL lawn mowers are designed to deliver a great cut even when it's been raining, thanks to the airflow generated by the blade, the shape of the deck and the vents in the grass catcher box.


#1Cleaning your RMA 443 C

When you have finished using the mower, remove the battery and clean using a damp cloth or soft brush. Always wear gloves and tie back long wear when cleaning or maintaining your mower.

#2Storing your RMA 443 C

Store your RMA 443 C in a clean and dry area away from children at all times. Don't forget you can fold the handle over and put the grass box on top so it takes up less space.

#3Looking after your battery

Don't use a damp or wet battery in your RMA 443 C and avoid using them in extreme temperatures (very hot or very cold). Find out more about looking after your battery on our blog.

#4Using a mulching kit

You can also buy a mulching kit for your RMA 443 C. This means that instead of collecting the grass clippings in the catcher box, you use the mulching kit to cut the clippings finely and drop them back on to the lawn as a natural fertiliser. Find out more about mulching on the STIHL Blog.

#5Leaves on the lawn

Did you know you can use your RMA 443 C to collect and shred leaves on your lawn? Switching off the eco mode means that the blade speed does not drop and so the mower can lift leaves with ease.

#6Check 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.
