Ideal push mower for Home Gardens

The RMA 243 from STIHL is a battery-powered push-along lawn mower designed for entry-level users looking to cut small to medium-sized lawns at home. Part of a new range of 2 Series battery-powered lawn mowers, it’s a lightweight and quiet mower that is fitted with innovative key features that make this the ideal choice for home gardeners.

This lawn mower is built with a sheet steel deck, has a 41 cm cutting width and single point height adjustment that is adjustable between 20 – 100 mm. The RMA 243 is part of the AK System range of tools and is powered by an AK 20 battery that is interchangeable with other machines across the range. There are two slots in the powerhead for two AK batteries, so when the first runs out of power you can quickly switch to the second. On a full charge with the recommended AK 20 battery you will be able to mow lawns up to 230 m2.

The RMA 243 has 4 different ways of mowing. No additional tools are required but we do recommend you refer to the owner’s manual before working. You can either:

  • Cut & collect with the grass catcher box fitted
  • Cut & drop by removing the grass catcher box
  • Side discharge with the flap that is integrated into the deck
  • Mulch with the multi-blade and mulching attachment

The comfort mono-handlebar allows easy access to the grass catcher box, making it easier to remove and empty when it’s full – plus, thanks to the fill level indicator on the grass catcher box you’ll know exactly when to empty the box too! The 52-litre grass catcher box is ergonomically designed and easy to fully open for fast emptying. The sturdy mono-handlebar is height adjustable and foldable for compact storage after use.

• Mono handlebar for easy storage and grass box access
• 52l grass catcher box with fill level indicator
• Side discharge and mulch plug included
• Single point height adjustment
