STIHL RM 448 V Petrol Lawn Mower – 46cm Vario Drive

The STIHL RM 448 V petrol lawn mower is a premium self-propelled mower with Vario wheel drive, built for homeowners maintaining medium-sized to large lawns. Part of the advanced 4 Series range from :contentReference[oaicite:1]{index=1}, it combines lightweight durability, powerful performance and flexible speed control for a comfortable mowing experience.

The RM 448 V features a rugged double-layer polymer deck that is lightweight, rust-proof, UV resistant and petrol resistant, delivering long-term durability without unnecessary weight. With a 46cm (18") cutting width, it strikes the perfect balance between efficient coverage and easy manoeuvrability around borders, paths and obstacles.

Power is provided by the STIHL EVC 300 petrol engine, which offers reliable, easy starting in both cold and warm conditions. The standout feature of this model is the Vario wheel drive, allowing you to infinitely adjust the mowing speed via the control lever on the handlebar. This means you can adapt the pace to suit your walking speed, grass length and terrain—ideal for changing conditions across the lawn.

Cutting height adjustment is quick and precise thanks to the central single-point height adjustment, with settings from 20mm to 100mm. A clear scale shows the selected height, making it easy to tailor your cut throughout the growing season.

With its versatile 4-in-1 mowing system, the RM 448 V adapts to all lawn care preferences. You can collect clippings, cut and drop, use the integrated side discharge, or mulch using the supplied multi-blade and mulching attachment. Mulching finely shreds grass clippings and returns them evenly to the turf, helping to fertilise the lawn naturally.

User comfort and convenience are enhanced by the mono-handlebar design, which provides unobstructed access to the 52-litre grass catcher box. The catcher features a fill-level indicator and folding mechanism for fast, clean emptying. The handlebar is height adjustable, foldable for compact storage, and finished with a super-soft ergonomic grip to absorb vibrations during mowing. The mono-handlebar is also backed by a 10-year domestic warranty.
