The RMA 453 PV from STIHL is a battery-powered lawn mower with variable speed drive, designed for users looking to cut large lawns. This 4 Series battery-powered lawn mower is quiet and packs plenty of power – making it the ideal choice for gardeners.

  • Cordless lawn mower with 51 cm cutting width and Vario wheel drive
  • Individual tool without battery and without charger
  • For medium-sized areas of lawn
  • Sequential battery discharge with automatic switchover feature
  • Cutting height can be adjusted from 20 mm to 100 mm
  • Fitted with 55-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 51 cm cutting width and single point height adjustment that is adjustable between 20 – 100 mm. The RMA 453 PV is part of the AP System range of tools and is powered by an AP 300 S battery that is interchangeable with other machines across the range. This lawn mower is fitted with sequential battery discharge, which means the lawn mower has an automatic switchover feature – so when one battery runs out of power, it will automatically switch over to the next one. On a full charge with the recommended AP 300 S battery you will be able to mow lawns up to 450 m2, which becomes 900 m2 when the lawn mower is used with two AP 300 S batteries.

The RMA 453 PV 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 RMA 453 PV has a built-in electronic interface on the mono-handlebar which shows useful information such as the battery charge, the ability to switch between mowing modes and adjust the motor speed levels. 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 55-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.
