Product Information

Full details

The Mountfield SP555V is designed for homeowners with medium to large lawns who require a powerful, efficient, and versatile mowing solution. Featuring a robust Honda GCVx170 engine and a wide 53cm cutting deck, it excels at reducing total mowing time while providing a professional-grade finish. While it offers premium performance and build quality, its heavy-duty construction means it is heavier than entry-level push mowers, which may require more effort to maneuver in tighter garden spaces.

FAQs

Does this mower require assembly?

No, the Mountfield SP555V arrives fully assembled and ready for use.

Can I mulch my grass with this model?

Yes, it includes a dedicated mulching plug that allows you to recycle clippings back onto the lawn.

What size garden is this mower suitable for?

It is specifically engineered for medium to large gardens due to its 53cm cutting width.

Is the speed of the mower adjustable?

Yes, it features a variable speed transmission, allowing you to control the pace of the self-propulsion.

How do I clean the cutting deck?

Use the built-in hose connector port on the deck. Attach your garden hose, turn on the water, and run the mower with the blades engaged to wash away debris.

What type of engine does it use?

It uses a professional-grade Honda GCVx170 Autochoke engine.

Troubleshooting

Engine fails to start

Check that the spark plug lead is securely attached and ensure the fuel tank has fresh, unleaded petrol.

Mower produces a ragged cut

Inspect the Twinclip blades for debris or dullness; ensure the deck is free of packed-in grass that might prevent a clean airflow.

Excessive vibration during use

Check that the blade is properly balanced and tightened. Ensure all engine mounting bolts are secure.

Pros and Cons

Pros

  • High-performance Honda engine ensures reliability
  • Twinclip blade provides an exceptionally neat cut
  • Large cutting width reduces overall mowing time
  • Flexible 3-in-1 functionality supports mulching and collection
  • Adjustable handlebars for ergonomic comfort and storage

Cons

  • Heavier weight compared to smaller plastic-deck models
  • Requires regular petrol engine maintenance
  • May be cumbersome in very small or intricate garden layouts

Setup, Compatibility & Care

The mower arrives fully assembled, allowing you to begin maintenance and operation immediately after adding oil and fresh petrol. To maintain the hybrid steel/aluminium chassis, use the integrated hose connector after each use: attach a standard garden hose, start the engine, and run the blades to clear out residual grass. Regularly check the engine oil level before starting and replace the air filter at the start of every season to ensure the Honda engine operates at peak performance. For winter storage, ensure the fuel tank is drained or treated with a stabilizer and fold the handlebars to save space in your shed or garage.
