Why Choose This Lawnmower:

The STIHL RM4RT Lawnmower combines professional cutting performance with a premium striped finish.

Built to STIHL’s professional standards, it delivers precision, durability and excellent results on every cut.

Ideal for large lawns up to 2500m², the RM4RT self-propelled mulching mower features optimised design, robustness and high quality equipment such as QuickFix, quick release handles for compact storage and transport, skirt protectors and a powerful Kohler engine. Mulching saves time as the grass clippings do not have to disposed of, instead the shredded grass is returned to the lawn acting as a natural fertiliser.

Additional features such as SmartChoke, make the RM4RT easy to start and the double ball-bearing wheels and excellent grip make the mower very comfortable to use, while front and rear carrying handles help with transportation. The RM4RT comes with a 5 year extended domestic warranty (subject to registration and annual servicing).
