The RMA 448 V from STIHL is a battery-powered self-propelled lawn mower designed for users looking to cut medium-sized to large lawns at home. Part of a new range of 4 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 gardeners at home.

  • Cordless lawn mower with a 46 cm cutting width and Vario drive
  • Individual tool without battery and without charger
  • For medium-sized areas of lawn
  • Easy handling thanks to the height-adjustable handlebar
  • Cutting height can be adjusted from 20 mm to 100 mm
  • Fitted with 52-litre grass collection box with fill-level display

This lawn mower is built with a rugged polymer deck that is lightweight, rust proof and double layered for additional stability. It’s UV resistant, has a 46 cm cutting width and single point height adjustment that is adjustable between 20 – 100 mm. The RMA 448 V is part of the AK System range of tools and is powered by an AK 30 S 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 30 S battery you will be able to mow lawns up to 340 m2.

The RMA 448 V 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 by switching it to mulch mode

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.
