MOUNTFIELD S421R PD Petrol Lawnmower

Achieve Beautiful Lawn Stripes with Ease

The Mountfield S421R PD is a compact yet powerful petrol roller mower designed to create the perfect striped lawn. Ideal for smaller gardens, this mower combines high performance with user-friendly features. Whether you’re enhancing your lawn’s appearance or maintaining it regularly, this mower offers a professional finish with minimal effort.

Powerful STIGA Engine for Reliable Performance

At the core of the S421R PD is a dependable STIGA ST140 Autochoke petrol engine. This 139cc engine produces up to 2.2kW of power at 2900 rpm. The Autochoke system ensures easy starting, even after storage or during colder weather. Its strong output helps drive the 41 cm cutting blade effortlessly through longer grass.

Self-Propelled for Comfortable Lawn Care

The mower is equipped with a self-propelled drive system, offering a fixed forward speed of 4.1 km/h. This feature removes the strain of pushing, letting you guide the mower smoothly across the lawn. It’s especially helpful on slopes or uneven ground, where consistent movement improves mowing results.

Rear Roller for a Classic Striped Finish

The S421R PD features a full-width rear roller, perfect for producing traditional lawn stripes. As the roller presses down the grass, it creates a neat, attractive pattern. It also enhances control when trimming edges by preventing tipping. This is ideal for gardeners wanting a clean, professional look.

Precision Cutting and Height Adjustment

A centralised lever allows quick height changes with minimal effort. You can choose from several cutting heights to suit the season or grass type. The sharp steel blade ensures each pass delivers a clean, even cut across the entire lawn. Whether maintaining a neat finish or handling slightly overgrown patches, it adapts easily.

Efficient Grass Collection and Clear Indicators

The mower comes with a 55-litre hybrid grass collector featuring a hard top and durable textile sides. This generous capacity reduces how often you need to stop and empty clippings. A built-in indicator clearly shows when the bag is full, preventing overflows or clogging. The airflow system improves collection efficiency, even in damp conditions.

Built to Last with Sturdy Design

A robust steel chassis protects internal components and extends the mower’s life, even with regular use. The signature Mountfield red finish adds a sleek, professional appearance to this hard-working tool. Despite its solid build, the mower remains easy to handle, store, and manoeuvre around flower beds or garden features.

Perfect for Small to Medium Gardens

If your garden measures up to 20 metres squared, the S421R PD is an ideal match. It delivers excellent results in compact spaces without sacrificing power or control. With its smooth operation, sharp cutting blade, and iconic striped finish, it’s a brilliant choice for homeowners who take pride in their lawn.
