RM 4 RT Mulching lawn mower
Robust petrol mulching mower with 1-speed drive
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).

Standard features
-
Easy start engine
Thanks to the SmartChoke technology, the engine starts up reliably and with minimal effort both during cold and warm starting.

Self-propelled
Self-propelled STIHL lawn mowers take the effort out of lawn mowing. The drive mechanism propels the mower without it physically having to be pushed. This makes working easier, especially on large lawns and inclines.

Mulching blade
With the specially shaped mulching blade, the grass is cut in stages and shredded into fine particles in the housing. The fine grass clippings can then fall back onto the turf as a nutritious fertiliser.

Smooth running wheels
The smooth running wheels of the STIHL lawn mowers are extremely robust and hard-wearing. They have been equipped with a traction pattern and directional stability tread pattern for effortless manoeuvring and to help hold perfect line during mowing.
