MOUNTFIELD S421R PD Petrol Lawnmower

Create Perfect Lawn Stripes with Ease

The Mountfield S421R PD is a petrol roller mower designed for creating a beautiful, professional-looking striped lawn. Compact yet powerful, it is ideal for smaller gardens where precision and a polished finish matter. With a focus on both performance and convenience, this mower is perfect for homeowners who want effortless, high-quality results.

Powerful Engine for Smooth Performance

At the heart of the S421R PD is the reliable STIGA ST140 Autochoke petrol engine. This 139cc engine produces an impressive 2.2kW of power at 2900 rpm. The Autochoke technology ensures easy starting, even after periods of storage or during colder weather. This dependable power output allows the 41 cm cutting blade to glide smoothly through grass, making mowing quicker and more efficient.

Effortless Lawn Care with Self-Propulsion

The self-propelled system removes the need for pushing, allowing you to mow comfortably without strain. Operating at a fixed forward speed of 4.1 km/h, the mower moves consistently across both flat lawns and sloped areas. This feature is especially helpful for longer mowing sessions or gardens with uneven terrain, where pushing a mower can be tiring.

Rear Roller for a Professional Striped Finish

The full-width rear roller gives your lawn the classic striped effect admired by professionals. By pressing the grass down after cutting, the roller leaves a clean, defined pattern. It also enhances control when working close to borders, reducing the chance of tipping. For gardeners who value a neat, stylish finish, this roller is a standout feature.

Cutting Precision with Adjustable Heights

The S421R PD offers versatile cutting through a central height adjustment lever. With multiple height settings, you can adapt the cut to suit seasonal conditions or personal preferences. The sharp steel blade ensures every pass is clean and precise. Whether you need a close trim or want to leave the grass slightly longer, adjustments are quick and straightforward.

Efficient Grass Collection with Clear Indicators

Clippings are collected in a large 55-litre hybrid grass bag with a hard top and durable textile sides. This spacious collector minimises interruptions by reducing how often it needs to be emptied. A convenient ‘bag full’ indicator tells you exactly when it’s time to empty, preventing blockages and maintaining smooth operation. The advanced airflow system ensures excellent collection, even when the grass is damp.

Robust Construction Built to Last

The mower’s steel chassis provides exceptional durability, protecting the internal components from wear and tear. The signature Mountfield red finish adds a modern, professional touch to its sturdy design. Despite its strong build, the S421R PD is easy to handle, store, and manoeuvre around garden features or tight spaces.

An Ideal Choice for Small Gardens

For gardens up to 20 metres squared, this mower is a perfect fit. It combines power, precision, and convenience, ensuring exceptional results with minimal effort. With its self-propulsion, sharp cutting performance, and iconic striped finish, the Mountfield S421R PD is a top choice for homeowners who want their lawn to look its absolute best.
