- Self-propelled with variable speed control for effortless mowing on any terrain.

The Mountfield SP555 V stands as the brand’s flagship 4-wheel, self-propelled petrol lawnmower, engineered for gardeners who demand the ultimate in performance and finish. Packed with top-of-the-range features, this mower is perfectly suited for maintaining larger gardens up to 2500m² with ease and precision.
Powerful Honda Engine & Variable Speed Drive
At the heart of the SP555 V is a superb 167cc Honda GCVx170 Autochoke petrol engine, providing reliable power and effortless starting. The self-propelled, rear-wheel-drive transmission features a speed variator, allowing you to adjust the forward speed from 2.7 to 4.4 Km/h. This versatile control ensures a comfortable pace, whether you’re navigating flat lawns, complex areas, or gentle slopes.
Advanced Twinclip Cutting System
This mower produces a superior cut thanks to its innovative Twinclip blade technology. The special blade features four cutting surfaces instead of the usual two. The first cutting edge reduces the initial length of the grass, with the second edge cutting it down to the desired finished length. This double-cutting action makes tackling grass an effortless task while leaving a finish comparable to a cylinder mower. The cutting height is easily adjusted via a single centralised lever, offering seven positions ranging from 25mm to 77mm to suit any lawn condition.
Durable Construction & User-Friendly Features
The chassis is a robust combination of galvanised steel and aluminium, ensuring strength and longevity. An anti-scalp plate at the front of the deck prevents damage to the turf on uneven ground while improving airflow for optimised collection. For user comfort, the Vibration Control System (VCS) isolates engine vibrations, making for a more enjoyable mowing experience. The ergonomic handlebars are adjustable and foldable for easy storage, and cleaning is simplified with the integrated washing link – just connect a hose to rinse the deck. Clippings can be collected in the large 70-litre textile bag, which includes a ‘bag full’ indicator, or finely shredded and returned to the lawn using the included mulching plug to provide natural fertiliser.

Frequently Asked Questions
Who is the Mountfield SP555 V lawnmower best suited for?
The Mountfield SP555 V is ideal for homeowners with large lawns, up to approximately 2500m² (over half an acre). Its wide 53cm cutting deck, powerful Honda engine, and self-propelled variable speed drive make it perfect for those who want to mow significant areas efficiently and with a premium finish.
What is the main benefit of the Twinclip blade?
The Twinclip blade’s primary benefit is its superior cutting quality. It has four cutting edges instead of two. The first edge makes an initial cut, and the second edge cuts the clippings again, refining the finish and shredding the grass into smaller pieces. This results in a cleaner lawn appearance and more efficient collection or mulching.
Can this mower handle slopes or uneven ground?
Yes, the SP555 V is well-equipped for varied terrain. The self-propelled drive with variable speed control makes it easier to manage slopes, as the mower does the hard work. Additionally, the anti-scalp plate at the front of the cutting deck helps to prevent the blade from digging into the turf on uneven surfaces, ensuring a more consistent cut.
How do I clean the mower deck after use?
Cleaning is made simple with the integrated washing link. After mowing, you can connect a standard garden hose to the port on the deck. Running the mower’s engine while the water is flowing will clean the underside of the deck, removing grass clippings and preventing build-up.
