With its impressive 53cm cutting width, this mower is perfectly suited for gardeners with medium to larger-sized lawns up to 2500 m² who demand a pristine finish. Powerful Honda Performance At the heart of this machine is a powerful 167cc Honda GCVx170 OHV Autochoke petrol engine, renowned for its reliability and easy starting. This engine drives a heavy-duty, high-torque cone clutch transmission, providing robust power to both the cutting blade and the full-width steel rear roller. The self-propelled drive system features stepless variable speed control, allowing the operator to adjust the forward pace from 3 to 4.9 km/h to match walking speed and grass conditions with ease. Superior Cutting & Collection The SP555R V employs the innovative Mountfield Twinclip blade system, which features four cutting edges. The first edge reduces the initial length of the grass, while the second edge cuts it down to the desired height. This process creates finer clippings, which significantly improves collection efficiency by up to 20%. This means the capacious 80-litre textile grass collector holds more, reducing the frequency of stops to empty. Cutting height is centrally adjusted through eight positions, ranging from 13mm to 65mm, ensuring it can tackle any grass situation with precision. Robust Design & User Comfort Durability is a key feature, with a robust and stylish galvanised steel and aluminium chassis finished in Mountfield Red. User comfort is enhanced by the ergonomic handlebar with a soft grip, which is adjustable by a simple button. The Vibe Control System (VCS) minimises vibrations felt by the user, making mowing more comfortable. For easy cleaning and maintenance, an integrated washing link is situated on the deck. After use, a single click folds the handlebars down to one of three positions for convenient storage in a shed or garage.

Frequently Asked Questions Frequently Asked Questions What size garden is the Mountfield SP555R V suitable for? With its wide 53cm (approx. 21″) cutting deck and powerful Honda engine, the SP555R V is ideal for medium to larger-sized lawns, capable of handling areas up to 2500 m². What is the main advantage of the rear roller on this mower? The full-width, heavy-duty steel rear roller is designed to create the classic, sharp stripes synonymous with a well-kept British lawn. It also provides stability and balance, especially along lawn edges. How does the Mountfield Twinclip blade system work? The Twinclip blade features four cutting edges instead of the usual two. The first edge makes an initial cut, and the second edge cuts the grass again into finer clippings. This improves collection efficiency by up to 20% and leaves a cleaner finish. Is the mowing speed adjustable? Yes, this is a variable speed, self-propelled mower. The forward speed can be adjusted steplessly between 3 and 4.9 Km/h, allowing you to match the mowing pace to the terrain and grass conditions. Does this lawnmower require assembly when purchased from Sims? No. Unlike ‘box-shifters’, every petrol lawn mower from Sims Garden Machinery undergoes a full Pre-Delivery Inspection (PDI) by our trained mechanics. For local customers, we offer free delivery and a full handover to demonstrate the controls and safety features. User Manuals / Downloads View Mountfield Brochure
