STIHL RMA 453 PV cordless lawn mower, 51 cm, without battery and charger

If you want to cut a medium-sized lawn without fuss, this cordless mower keeps you moving. The STIHL RMA 453 PV adds variable self-drive so you set the pace, then lets you choose to collect, mulch or side-discharge depending on the job.

Powered by the STIHL AP System with sequential discharge, it automatically switches to the second battery when the first is empty, helping you cover more ground with fewer stops. A 55 L folding catcher, central 7-step height adjuster and an ergonomic, height-adjustable handlebar round off a practical, all-round setup.

Where it works best

• Medium lawns where you want a clean finish in fewer passes (51 cm cut)
• Mixed weeks of collecting or mulching without tool changes
• Gentle slopes and longer stretches thanks to vario wheel drive
• Damp conditions where IPX4 splash protection adds confidence

Why you’ll like it

• Set your pace: Vario self-drive up to 4.5 km/h
• Flexible cutting: Multiblade, mulch flap and side discharge
• Fewer interruptions: Sequential use of two AP batteries
• Easy handling: 55 L catcher with fill-level indicator

In daily use

The interactive handlebar display keeps you informed about battery status, mode and speed level at a glance. Eco mode automatically adapts the motor speed to save energy, while the optimized blade design reduces power draw. Comfort wheels and a robust polymer deck make it easy to steer and durable without adding weight.

Advice from gardenmachineshop.com

Cut a little higher on the first pass (e.g. 60–70 mm), then drop to your preferred height—this protects the lawn and extends runtime.
