Mountfield SP555V Petrol Lawn Mower

The Mountfield SP555V petrol lawn mower is a premium 53cm self-propelled mower designed for large lawns of up to 2,500m². It combines a powerful Honda GCVx170 Autochoke engine, variable-speed drive and Mountfield’s Twinclip cutting system to help you cover more ground while maintaining a clean, well-collected finish.

This is a strong choice for gardeners who want the cutting capacity of a large petrol mower but also want to control the mower’s forward speed. The SP555V can collect, mulch or rear-discharge grass and includes a generous 70-litre collector, seven cutting-height settings and an integrated deck-washing connection.

Why Masseys recommends the Mountfield SP555V

Masseys recommends the SP555V for customers with a large lawn who want a premium four-wheel petrol mower without moving up to a ride-on machine. Its 53cm cutting width covers open areas efficiently, while the variable-speed transmission lets you slow down near trees, borders and obstacles or increase the pace on longer straight sections.

The Twinclip blade and large collector make it particularly useful when grass collection and finish quality are priorities. The Honda engine, vibration-control system and adjustable soft-grip handle also make it better suited to longer mowing sessions than a basic fixed-speed petrol mower.

At 45kg, this is a substantial machine. Customers who need to lift a mower regularly, have a much smaller lawn or want minimal engine maintenance may prefer a lighter model or one of our cordless and electric lawn mowers. Customers wanting defined lawn stripes should compare it with the Mountfield SP555RV rear-roller mower.

Key features and benefits

Honda GCVx170 Autochoke engine

The 167cc Honda GCVx170 OHV engine delivers 3.3kW of power at 2,900rpm. Autochoke simplifies starting by automatically managing the choke setting, while the engine provides the torque required for longer grass and larger mowing areas.

Variable-speed self-propelled drive

The rear-wheel-drive transmission provides a forward speed range of approximately 2.7 to 4.4km/h. This allows you to adjust the mower to your walking pace and the conditions instead of being restricted to a single fixed speed.

53cm cutting width for large lawns

The wide 53cm cutting deck reduces the number of passes required across a large garden. Mountfield recommends the SP555V for mowing areas of up to 2,500m², making it a practical option for substantial domestic lawns.

Twinclip cutting technology

Mountfield’s Twinclip blade has four cutting surfaces. Grass is cut progressively into finer clippings, helping improve collection performance and produce a cleaner finish than a conventional two-edge rotary blade.

Collect, mulch or rear-discharge

The SP555V provides three grass-management options:

• Collecting for a tidy finish using the 70-litre textile collector.
• Mulching to finely cut and return clippings to the lawn using the supplied mulching plug.
• Rear discharge for longer grass or areas where collection is not required.

Seven centrally adjusted cutting heights

A single central lever adjusts the cutting height through seven positions from 25mm to 77mm. This allows you to choose a shorter finish in favourable summer conditions or raise the deck for longer, damp or uneven grass.

Large 70-litre grass collector

The high-capacity collector reduces the number of stops required when mowing a large lawn. Its textile construction supports airflow, while the full indicator helps you identify when the collector needs emptying.

Durable chassis and anti-scalp protection

The mower combines galvanised steel and aluminium chassis components for strength, rigidity and corrosion resistance. A front anti-scalp plate helps protect uneven areas of the lawn and supports airflow beneath the deck.

Comfortable controls and easier cleaning

The SP555V includes an adjustable soft-grip handle, Mountfield’s Vibration Control System and wheels running on ball bearings. The built-in washing link allows a garden hose to be connected to the deck for easier cleaning after use.

Is the Mountfield SP555V right for your garden?

The SP555V is particularly suitable when:

• Your lawn is large, open or fast growing.
• You want a wide 53cm cut to reduce mowing time.

Frequently asked questions

What size lawn is the Mountfield SP555V suitable for?

Mountfield recommends the SP555V for mowing areas of up to 2,500m². Its 53cm cutting width, self-propelled drive and 70-litre collector make it particularly well suited to large domestic lawns.

Does the Mountfield SP555V drive itself?

Yes. It has rear-wheel self-propelled drive and a variable-speed transmission. You guide the mower and select a suitable forward speed rather than having to push its full weight.

What is Mountfield Twinclip technology?

The Twinclip blade has four cutting surfaces. It progressively cuts grass into finer pieces, supporting efficient collection, mulching and a clean finish.

Can the SP555V mulch grass?

Yes. A mulching plug is supplied. When fitted, the mower finely cuts the clippings and redistributes them across the lawn instead of collecting them.

Can it cut long or damp grass?

The Honda engine, raised cutting-height settings and rear-discharge option make the mower capable of handling more demanding growth. For the best finish and collection performance, avoid cutting extremely wet grass and remove no more than roughly one-third of the grass height in a single pass.

Does the SP555V create lawn stripes?

The SP555V is a four-wheel rotary mower and does not have a full-width rear roller. For more pronounced stripes, compare it with the Mountfield SP555RV petrol roller mower.

Is the mower difficult to manoeuvre?

The variable-speed drive reduces pushing effort, but the mower weighs 45kg and has a wide 53cm deck. It is best suited to larger lawns rather than small gardens with many narrow spaces or tight turns.

Can Masseys assemble and service the mower?

Yes. Optional Ready to Mow assembly is available, and Masseys provides ongoing lawn mower servicing and repairs through its garden machinery workshop.
