STIHL RMA 448 RV Rear Roller Cordless Lawn Mower – 46cm

The STIHL RMA 448 RV rear roller cordless lawn mower is designed for homeowners who want a perfectly striped finish on medium to large lawns, without the noise and emissions of petrol. As part of STIHL’s premium 4 Series cordless lawn mower range, it combines professional lawn aesthetics with quiet, battery-powered convenience.

The standout feature of the RMA 448 RV is its integrated rear roller, manufactured from durable polymer material. This roller allows you to create clean, traditional lawn stripes while also improving stability and control on flatter lawns.

The mower features a rugged double-layer polymer deck that is lightweight, rust-proof and UV resistant. With a 46cm (18") cutting width and central single-point height adjustment ranging from 15mm to 60mm, the RMA 448 RV delivers precise results across a wide range of lawn conditions.

Powered by STIHL’s AK System, the RMA 448 RV is designed to run on the AK 30 S battery (recommended). Two battery slots are built into the powerhead, allowing you to carry a spare battery and switch over quickly when the first is depleted. With the recommended AK 30 S battery, you can mow up to 340 m² on a single charge (working area may vary depending on grass conditions and cutting height).

The RMA 448 RV offers two mowing modes: cut and collect, or mulch mode. Grass clippings are collected in a generous 52-litre folding grass catcher with a fill-level indicator for efficient, mess-free emptying.

Comfort is enhanced by the mono-comfort handlebar, which provides easy access to the grass box and can be adjusted to suit the user’s height. The handlebar folds down for compact storage and is covered by a 10-year domestic warranty.
