STIHL RM 453 T Petrol Lawn Mower – 51cm Self-Propelled

The STIHL RM 453 T petrol lawn mower is a robust single-speed, self-propelled mower built for challenging, medium-sized to large gardens. Part of the advanced 4 Series from :contentReference[oaicite:1]{index=1}, it combines a wide cutting width with lightweight durability and versatile mowing options for confident lawn care at home.

The RM 453 T features a rugged double-layer polymer deck that is lightweight, rust-proof, UV resistant and petrol resistant. This high-resistance housing delivers long service life without unnecessary weight. With a generous 51cm (21") cutting width, you can cover larger areas quickly while maintaining excellent manoeuvrability.

Power comes from the dependable STIHL EVC 300 petrol engine, designed with an easy-start system for reliable starting in both cold and warm conditions. The single-speed wheel drive reduces effort on slopes and uneven ground, helping you progress faster with less fatigue. On a full tank, the RM 453 T can mow lawns of up to 1200 m².

Adapting to changing grass conditions is simple thanks to the central single-point cutting height adjustment, offering settings from 20mm to 100mm. A clear scale shows the selected height, so you can fine-tune your cut throughout the season.

The RM 453 T includes a flexible 4-in-1 mowing system, allowing you to collect grass, cut and drop, use the integrated side discharge, or mulch using the supplied multi-blade and mulching attachment. Mulching finely shreds clippings and redistributes them evenly into the turf, helping to fertilise your lawn naturally.

Comfort and convenience are enhanced by the mono-handlebar design, which provides easy access to the 55-litre grass catcher box. The catcher features a fill-level indicator and folding design for quick, 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.
