The Mountfield SP42 is a reliable and efficient self-propelled petrol lawn mower, perfect for small to medium-sized gardens up to 300m². Equipped with a 123cc STIGA ST120 Autochoke engine, it delivers consistent performance and effortless mowing.
With a 41cm cutting width, the SP42 offers excellent coverage, while the six adjustable cutting heights (22mm-65mm) allow you to achieve the perfect lawn finish. The centralized single-lever height adjustment makes switching between cutting heights quick and easy.
The durable steel chassis ensures long-term reliability, while the self-propelled system at a fixed speed of 3.7 km/h helps reduce fatigue, especially on uneven terrains. The 60-litre hybrid grass collector, with a bag full indicator, efficiently gathers clippings to keep your lawn neat. Additionally, the included mulching plug allows you to recycle grass clippings, returning nutrients to the lawn for a healthier, greener appearance.
Designed with user comfort in mind, the ergonomic handlebar offers a comfortable grip, and its foldable design ensures easy storage. Backed by a 5-year warranty, the Mountfield SP42 is a practical, high-performance solution for home gardeners.
