The STIHL RM 4 RT Petrol Mulching Lawn Mower designed for large lawns up to 2,500m². Featuring a powerful Kohler engine, durable construction, single-speed wheel drive and an efficient mulching system, it delivers excellent mowing performance while naturally fertilising your lawn.

The STIHL RM 4 RT Petrol Mulching Lawn Mower is a professional-quality mulching mower designed for homeowners and landowners who want an efficient, low-maintenance solution for keeping larger lawns healthy and well maintained.

Suitable for lawns of up to 2,500m², the RM 4 RT features a highly effective mulching system that finely shreds grass clippings and returns them directly to the lawn. This natural mulch acts as an organic fertiliser, helping to promote stronger, greener grass while eliminating the need to collect and dispose of clippings.

Powered by a reliable Kohler petrol engine, the RM 4 RT delivers strong and consistent performance for tackling larger mowing tasks. STIHL’s SmartChoke technology simplifies starting by automatically adjusting the engine for reliable ignition with minimal effort.

The mower’s single-speed self-propelled drive system helps reduce operator fatigue and makes maintaining larger areas significantly easier than using a push mower.

Built for durability, the RM 4 RT features a robust construction with integrated skirt protectors to help safeguard the deck during operation. Double ball-bearing wheels provide smooth movement, excellent traction and improved manoeuvrability across varying lawn conditions.

For added convenience, the mower is equipped with QuickFix quick-release handles, allowing the machine to be folded quickly for compact storage and easier transport. Front and rear carrying handles further improve handling when lifting or moving the mower.

Combining reliability, ease of use and the benefits of mulching technology, the STIHL RM 4 RT is an excellent choice for users seeking a premium mower capable of maintaining large lawns with minimal effort.
