Efficient and Versatile Mowing for Home Gardens

The STIHL RM 248.3 T is a petrol push-along lawn mower specifically engineered for entry-level users and home gardeners looking to maintain small to medium-sized lawns with ease. As part of STIHL’s 2 Series range, it combines a robust sheet steel deck with a practical 46 cm (approx. 18″) cutting width, making it a reliable choice for areas up to 1200 m². The mower is powered by a STIHL EVC 205 engine, featuring an easy-start system that ensures you can get to work quickly, whether the engine is cold or warm.

Advanced Features for a Superior Cut

This model offers exceptional flexibility with four different mowing methods available without requiring additional tools. You can choose to cut and collect using the 52-litre grass catcher box, cut and drop by simply removing the box, use the integrated side discharge flap, or mulch the clippings with the multi-blade and included mulching attachment. The grass box itself is designed for convenience, with a fill-level indicator to let you know when it’s time to empty and an ergonomic design for easy handling.

Comfort and usability are central to the RM 248.3 T’s design. The innovative comfort mono-handlebar not only provides easy access to the grass box but is also height-adjustable to suit any user and folds down for compact storage. A super-soft grip helps to absorb vibrations, making for a more comfortable mowing experience. The mower also features smooth-running wheels for excellent manoeuvrability and a simple-to-use central cutting height adjustment, offering a wide range of cutting heights from 20 mm to 100 mm.
