Description
The STIHL RM 4 RTP Petrol Mulching Lawn Mower is engineered specifically for professional landscapers, contractors and homeowners who demand outstanding performance from their lawn care equipment. Designed for frequent use on lawns up to 2,500m², this premium mulching mower combines a commercial-grade build with powerful performance and effortless operation, making it the ideal choice for maintaining large green spaces quickly and efficiently.
At the heart of the RM 4 RTP is a powerful 173cc STIHL HD775 OHV SC petrol engine, delivering 2.6kW of reliable power for tackling thick, dense grass with ease. Featuring STIHL’s Easy-Start system, the engine starts quickly whether cold or warm, reducing operator effort while providing dependable performance throughout long working days. Built for professional use, the engine offers impressive durability and smooth operation in demanding conditions.
The wide 53cm cutting deck allows you to cover large areas quickly while maintaining an exceptional finish. Unlike traditional collecting mowers, the RM 4 RTP has been purpose-built for mulching. Its specially designed mulching blade repeatedly cuts grass clippings into fine particles before evenly distributing them back into the lawn. This naturally returns valuable nutrients and moisture to the soil, promoting healthier grass growth while eliminating the need to collect and dispose of clippings.
Built to withstand the demands of professional use, the RM 4 RTP features a robust powder-coated aluminium deck with reinforced axle brackets and axle bolts for exceptional strength and longevity. Additional gearbox and crankshaft protection further improve durability, making this mower an excellent investment for commercial landscapers and users maintaining large properties on a regular basis.
The single-speed front-wheel drive system makes mowing far less physically demanding, especially across large lawns and gentle inclines. Travelling at approximately 4.6km/h, the drive system helps maintain a comfortable working pace while reducing fatigue during extended mowing sessions. Combined with STIHL’s anti-vibration technology and ergonomic super-soft handle, the mower remains comfortable to operate even over long periods.
Central cutting height adjustment allows you to select from five cutting heights between 30mm and 70mm using a single lever. This makes it quick and easy to adapt the mower to changing grass conditions throughout the season while maintaining a consistently professional finish. Smooth-running double ball-bearing wheels with aluminium rims provide excellent traction, directional stability and effortless manoeuvrability across a variety of lawn surfaces.
Practical features have been included throughout the design to improve day-to-day usability. Integrated front and rear carry handles make lifting and transporting the mower easier, while the Quick-Fix quick-release handlebar allows the mower to be folded without tools for compact storage and transport. These thoughtful features make the RM 4 RTP ideal for professionals moving between multiple sites throughout the working day.
Because the RM 4 RTP is designed exclusively for mulching, there is no grass collector to empty. This significantly reduces downtime and allows uninterrupted mowing, making it one of the most efficient ways to maintain regularly cut lawns. By recycling finely shredded grass clippings back into the turf, the mower also helps reduce the need for artificial fertilisers while supporting healthier, greener lawns naturally.
The STIHL RM 4 RTP Petrol Mulching Lawn Mower is the perfect choice for professional landscapers and homeowners looking for a robust, commercial-quality mulching mower. Featuring a powerful 173cc OHV engine, durable 53cm aluminium cutting deck, front-wheel drive and purpose-built mulching technology, the STIHL RM 4 RTP delivers exceptional reliability, outstanding cutting performance and healthier lawns with every mow.
