RM 4 RT Petrol Mulching Lawn Mower
Robust petrol mulching mower with 1-speed drive
Overview
Ideal for large lawns up to 2500m², the RM 4 RT 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 lawn mower 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 RM 4 RT comes with a 5 year extended domestic warranty (subject to registration and annual servicing).
