About the MOUNTFIELD SP46 Petrol Lawnmower

Confidently Mow Medium Lawns with Less Effort

The Mountfield SP46 petrol lawnmower is designed to make mowing feel smoother, faster, and far less tiring. With a wide 46 cm cutting deck, it’s ideal for medium-sized gardens and busy households. The self-propelled system removes the need for pushing, letting you steer rather than strain. Whether you’re tackling flat grass or uneven patches, it handles the job with reliable control.

Strong, Reliable Performance with Every Start

This mower is powered by a 139cc STIGA petrol engine, known for dependable, hassle-free performance throughout the season. Autochoke technology means it starts quickly, just pull the cord and begin mowing straight away. Even with long or damp grass, this engine keeps going without faltering. You can expect smooth running, consistent power, and easy maintenance every time.

Precision Cutting to Achieve a Healthier Lawn

The SP46 comes with a durable steel cutting blade designed for a clean and tidy finish across the whole lawn. With six central height settings between 22 mm and 65 mm, adjusting the cut is fast and easy. Whether you want a neat summer trim or a higher winter cut, you’ll always have the right setting available. This flexibility helps protect your lawn’s condition year-round.

Large Grass Collector for Fewer Disruptions

Mow for longer without constant stops thanks to the generous 60-litre textile grass bag. This breathable collector improves airflow for effective gathering and cleaner results. It includes a built-in bag full indicator, so you’ll know exactly when to empty it. This feature saves time and helps prevent mess while keeping your workflow smooth and efficient.

Mulch Your Grass for an Eco-Friendly Finish

The SP46 also includes a mulching plug for those who prefer to naturally feed their lawn. When attached, the plug finely chops clippings and redistributes them across the ground. This process returns moisture and nutrients back into the soil, encouraging lush growth over time. It’s a smart, sustainable option that reduces waste and supports healthy turf.

Lightweight, Compact and Built to Last

With a steel chassis and a weight of just 26 kg, this mower balances strength with easy handling. The robust frame resists bumps and knocks while offering stability on varied terrain. Foldable handles make storage simple, especially in tight garage or shed spaces. Its dark grey design adds a modern, professional look to the overall build.

An Excellent Choice for Everyday Lawn Care

If you’re maintaining a garden up to 40 metres squared, the SP46 fits your needs perfectly. It combines dependable engineering, efficient features, and practical comfort into one trusted machine. The self-propelled drive, STIGA engine, and mulching capability make it a standout solution for stress-free mowing. Choose the Mountfield SP46 for effortless performance and a great-looking lawn every week.
