Mountfield SP555R V Petrol Lawn Mower

Mountfield SP555R V petrol roller lawn mower

The Mountfield SP555R V is a premium self-propelled petrol roller lawn mower for medium-to-large formal lawns where productive mowing, strong grass collection and a traditional striped finish are priorities.

Its wide 53cm cutter deck reduces the number of passes required across larger areas, while the full-width steel rear roller bends the grass in alternating directions to create defined light and dark stripes.

A 167cc Honda GCVx170 OHV Autochoke engine powers both the cutting blade and variable-speed roller drive. The operator can adjust the forward speed to suit the mowing conditions, lawn layout and preferred walking pace.

Is the Mountfield SP555R V right for you?

Choose the SP555R V if:

• You have a medium-to-large, regularly maintained lawn
• Your mowing area is up to approximately 2,500m²
• You want a strong, traditional striped finish
• You need a wide cutting deck to reduce mowing time
• You want variable forward speed rather than a single fixed pace
• You primarily collect the grass rather than mulch or discharge it
• You value a Honda petrol engine and dealer workshop support
• You have sufficient storage and suitable access for a 53cm, 47kg mower

Consider another mower if:

• You have narrow gates, tight passages or many confined areas
• Your lawn is small enough that a 53cm mower would be unnecessarily bulky
• You need a lightweight machine that is regularly lifted into a vehicle
• You want to mulch or rear discharge the grass
• You do not require a rear roller or striped finish
• You require a mower specifically designed for regular commercial contracting

Why Masseys recommends the Mountfield SP555R V

Masseys recommends the SP555R V to customers with a substantial formal lawn who want to combine a wide cutting deck with the striped finish produced by a full-width rear roller.

The 53cm deck is particularly useful on larger, open areas because it covers more ground with each pass. The variable-speed drive also lets the operator slow down around trees, beds and tighter sections before increasing the pace on longer, unobstructed runs.

The SP555R V is a stronger recommendation than a conventional four-wheel mower when stripes are an important part of the required finish. Its full-width steel roller creates a more defined result than wheel marks alone and also supports the mower when cutting along lawn edges.

It is not the most versatile choice for customers who regularly switch between collection and mulching. In that situation, Masseys would normally recommend comparing it with the Mountfield SP555V, which uses the same 53cm format but offers collection, mulching and rear discharge instead of a full-width rear roller.

Full-width steel rear roller for lawn stripes

The mower’s full-width steel rear roller bends the grass as the machine travels across the lawn. When adjacent passes are completed in opposite directions, light reflects differently from the grass blades and creates alternating light and dark stripes.

The visibility of the stripes will depend on the grass type, cutting height, mowing direction and how regularly the lawn is maintained. Longer, healthy grass generally produces a more visible pattern than very short or sparse turf.

The rear roller also supports the mower when one side of the deck is positioned close to a lawn edge. Care should still be taken around drops, retaining walls and soft or damaged edges.

Mountfield Twinclip cutting system

The SP555R V uses Mountfield’s Twinclip blade system. The blade has four cutting surfaces and progressively reduces the grass into finer clippings before directing them into the collector.

Finer clippings can be packed more efficiently into the grass bag, helping the mower make effective use of its large 80-litre capacity. This reduces the number of stops required when mowing a larger lawn.

Collection performance will still depend on grass length, moisture, cutting height, forward speed and the condition of the collector fabric. Damp or overgrown grass may require a higher initial cutting setting and a slower mowing pace.

Honda GCVx170 petrol engine

The current SP555R V is powered by a 167cc Honda GCVx170 OHV four-stroke petrol engine with Autochoke.

The Autochoke system manages the starting mixture automatically, removing the need for a separate manual choke control. The engine is started using a conventional recoil cord.

Mountfield rates the engine output at approximately 3.3kW at 2,900rpm. Its fuel tank holds approximately 0.95 litres, and its engine-oil capacity is approximately 0.4 litres.

Fresh fuel, the correct oil and regular servicing are essential. Always follow the supplied operator and engine manuals for starting, refuelling, maintenance, transport and storage.

Variable-speed self-propelled drive

The mower drives itself through the rear roller while the operator controls its direction. The variable-speed system provides a forward range of approximately 3–4.9km/h.

A slower setting gives greater control around obstacles, corners and borders and can improve collection when the grass is longer or heavier.

A faster setting can reduce mowing time across open, regularly maintained sections. Unlike a fixed-speed mower, the SP555R V does not require the operator to maintain the same walking pace throughout the entire lawn.

53cm galvanised-steel cutter deck

The 53cm / 21in cutter deck is designed for productive mowing on medium-to-large lawns. Its width reduces the number of passes required compared with a smaller 41cm or 46cm machine.

The deck is made from galvanised steel and includes an integrated washing link. A garden hose can be connected after mowing to help clear grass residue from the underside of the deck.

Follow the cleaning procedure in the operator manual. Never work underneath the mower while the engine is running, and disconnect the spark-plug lead before carrying out maintenance where instructed.

Eight cutting heights from 13–65mm

A centralised adjustment system changes the cutting height through eight positions from approximately 13mm to 65mm.

Lower settings are intended for level, regularly maintained formal lawns in appropriate conditions. Higher settings are useful at the beginning of the season, during dry weather or when the grass has been allowed to grow longer.

Avoid removing an excessive proportion of the grass blade in one pass. If the lawn is long, begin with a higher setting and reduce the height gradually over later mowing sessions.

80-litre textile grass collector

The large 80-litre textile collector reduces the frequency of emptying stops and complements the mower’s wide cutting deck.

Keep the collector fabric clean and unobstructed. Dried grass and dust can restrict airflow and reduce collection performance.

The SP555R V is designed primarily for grass collection. It does not provide the mulching and rear-discharge modes available on the four-wheel Mountfield SP555V.

Adjustable handle and storage

The ergonomic soft-grip handlebar can be adjusted to suit different operators. Mountfield’s one-motion adjustment also allows the handle to fold for storage.

The mower remains a substantial machine at approximately 47kg and 560mm wide. Check access widths, storage space and transport arrangements before purchasing.

Mountfield lists the approximate operating dimensions as 1,680mm long, 560mm wide and 1,100mm high.
