Create a Flawless, Striped Lawn
The Mountfield S461R PD is a superb petrol lawn mower designed for gardeners who desire a precise cut and a traditional striped finish. Its key feature is the full-width, 127mm diameter rear roller, which not only creates beautiful stripes but also provides stability right up to the edge of borders. This model is an excellent choice for homeowners with medium-sized lawns up to 1200 m², offering a perfect blend of power, performance, and user-friendly features.
Powerful and Reliable STIGA Engine
At the core of the S461R PD is a punchy and reliable 166cc STIGA ST 170 OHV Autochoke engine. This modern four-stroke engine produces 2.6kW of power, ensuring it can handle both short and longer grass with ease. The Autochoke system simplifies starting, removing the need for priming or choke adjustments – just pull the recoil cord and the engine is ready to go. Its fixed RPM of 2900 ensures a consistent blade speed for a clean and efficient cut every time.
Effortless Mowing and Superb Collection
Mowing is made simple thanks to the self-propelled drive system. With a fixed forward speed of 4.1 Km/h, the mower does the hard work for you, gliding across the lawn with minimal effort required from the operator. The 46cm (approx. 18″) cutting width is handled by a sharp, durable steel blade, housed within a robust steel chassis for longevity. All clippings are efficiently collected in the large 55-litre hybrid grass bag, which features a ‘bag full’ indicator to let you know when it’s time to empty. Cutting height is easily adjusted via a single centralised lever, offering five positions from 20mm to 70mm to suit the conditions of your lawn.
Designed for Comfort and Convenience
Mountfield has equipped the S461R PD with several features for operator comfort. The ergonomic handlebar has a soft grip and is both adjustable and foldable, making it comfortable to use and compact for storage. A front handle is integrated into the bumper for easier lifting, and a built-in washing link allows for simple cleaning of the underside of the deck after use, helping to maintain performance.

Frequently Asked Questions
What size lawn is the Mountfield S461R PD suitable for?
The Mountfield S461R PD is perfectly suited for medium-sized lawns, with a recommended maximum mowing area of 1200 m². Its 46cm (approx. 18″) cutting width offers a great balance of coverage and manoeuvrability for typical British gardens.
How do I achieve the best striped finish with this mower?
This model features a large, 127mm full-width rear roller designed specifically to create a classic, striped finish. For the best results, mow in straight, parallel lines, slightly overlapping each pass. The weight of the roller gently bends the grass blades, creating the light and dark stripes you see on formal lawns and sports pitches.
What fuel and oil should I use in the STIGA engine?
The STIGA ST 170 engine requires standard unleaded petrol. For engine oil, it is crucial to use a high-quality SAE 30 four-stroke engine oil to ensure optimal performance and engine longevity. Please contact our team if you need to purchase the correct engine oil for this machine.
Is this lawnmower difficult to set up from the box?
The mower arrives from Mountfield mostly assembled. However, buying from an authorised dealer like Sims Garden Machinery removes any uncertainty. For local customers, we offer a free Pre-Delivery Inspection (PDI) where our trained mechanics fully assemble, fuel, oil, and test the mower. We also provide free local delivery and a handover demonstration to ensure you’re confident using it from the start.
