About the MOUNTFIELD SP46 ELITE Petrol Lawnmower
Premium Self-Propelled Mower with Powerful Honda Performance
The Mountfield SP46 Elite is a high-quality self-propelled mower designed for smooth, reliable mowing across medium-sized gardens. Fitted with a robust steel chassis and large rear wheels, this mower is engineered for comfort, control, and lasting performance. It’s powered by a premium Honda GCVx145 Autochoke engine, delivering dependable cutting power with minimal effort required from the user.
Honda Engine Offers Reliable and Easy Starting
At the heart of the SP46 Elite is a 145cc Honda GCVx145 autochoke petrol engine. This engine is renowned for its quiet, fuel-efficient operation and effortless starts. The Autochoke system ensures the mower starts quickly without any manual priming or adjustments. With Honda’s trusted technology under the hood, you get long-lasting performance and reliable power for everyday lawn care.
Self-Propelled Drive Makes Mowing Effortless
This mower features a single-speed self-propelled system that drives the machine forward at a steady pace. It’s especially helpful on sloped or uneven lawns, where pushing can become tiring. Simply squeeze the lever and guide the mower as it powers forward. You maintain control while letting the mower handle the movement.
Wide Cutting Width and Height Adjustment
The SP46 Elite has a 46 cm cutting width, allowing you to cover more ground in less time. A centralised lever provides six cutting heights, ranging from 22 mm to 80 mm. You can easily adjust the cutting level to suit different grass types and seasonal conditions. The precision steel blade delivers a crisp, clean cut with every pass.
Generous Grass Collector with Full Indicator
Clippings are collected in a spacious 60-litre hybrid canvas and hard-top bag. This collector is designed for airflow efficiency and holds more before needing emptying. A built-in ‘bag full’ indicator alerts you when it’s time to stop and empty. This keeps mowing uninterrupted and reduces the risk of overfilling or clogging.
Mulching Option for Natural Lawn Fertilising
Included with the mower is a mulching plug for those who prefer not to collect clippings. Mulching finely chops the grass and redistributes it onto the lawn. This process returns moisture and nutrients to the soil, promoting healthier grass growth. It’s a great way to save time and enhance your lawn’s condition naturally.
Compact Storage and Easy Maintenance
The foldable handlebars make storing the SP46 Elite simple and space-efficient. Its collapsable grass collector also flattens down neatly for easier storage. The steel deck offers durability, while the large rear wheels give added grip on bumpy or uneven lawns.
Perfect Choice for Medium-Sized Gardens
Whether you’re maintaining a front lawn or tending a medium-sized garden, the SP46 Elite offers reliable power and flexibility. Its Honda engine, smart features, and comfortable handling make lawn care quicker, easier, and more enjoyable every time.

Mark Parfitt –
First time I have bought a self propelled petrol mower always used electric hover mowers previously. Excellent starting and the height adjustment so easy with just the one handle.
Handles the sloping ground I need to cut around my static caravan effortlessly, so easy to use, and with the larger cutting diameter cutting is far quicker. Love the large grass collection bag, takes a lot of grass cuttings easy to take of and on.
A well made machine, the larger rear wheels handles the slopes and rough ground very well.
