Mountfield SP46 Self-Propelled Petrol Lawn Mower

The SP46 is a fantastic self-propelled, petrol-driven mower possessing all the features you need in a no-nonsense, hardworking, durable mower. The 46cm cutting width makes light work of medium-sized lawns and with six different cutting heights to choose from, means all grass lengths can be tackled.

  • Self-propelled - No need to push
  • 46cm/18" cutting width - Ideal for small / medium lawns
  • Reliable ST140 139cc 4 stroke engine
  • 60 litre grass bag with bag full indicator
  • Includes mulch plug

Main Features:

The Mountfield SP46 46cm self propelled lawn mower is a great little mower aimed at small to medium sized lawns. Being self propelled it powers itself meaning you don’t need to push and it takes the hard work out of gardening for you. Thanks to the quality components together with the robust steel chassis that has been powder coated in the traditional “Mountfield red” this SP46 really has been built for longevity.

The 46cm cutting width is generous and will ensure you get your grass mown in no time at all. The 6 pre-set cutting heights range from 22-65mm and offer plenty of versatility whatever the length of your grass. Easy to change the heights with a single lever you will soon have your grass neat and tidy.

The Stiga ST140 OHV auto choke 4 stroke 139cc engine is powerful, reliable and low on maintenance. Easy to start up with the standard recoil rope system you can be assured of reliable starts even in damp weather.

This versatile Mountfield SP46 46cm self propelled lawn mower offers you the choice between collecting, mulching or discharging. If you choose to collect then the sturdy canvas grass collector has a 60 litre capacity and features a clever bag full indicator and a hard top to minimise dust flying up as you mow your lawn. Very useful in dry and dusty conditions.

If the grass is longer and you decide you’d rather it wasn’t left to rot on your compost heap you can choose to discharge it, either from the back or side. It will wilt naturally on your lawn, however if you think it is at risk of being trodden into your house by pets or children then you might prefer to collect it.

If the conditions are right for mulching you will be pleased to know the efficient system finely cuts the grass clippings and returns them to your lawn where they will act as a natural and rich fertiliser. Mountfield suggests if you don’t have to collect the grass and empty the grass collector this could save you up to 30% of your time - this is a very attractive idea, we think so anyway! The mulching plug is included as standard.

This Mountfield SP46 features operator presence control which means the engine only runs when you are holding onto the handles. Let go and the engine simply cuts out and of course the blades will stop. This means the machine cannot be left to idle - this saves on petrol but also cuts the risk of accidents. We believe this is a great safety feature, as the machine cannot be accidentally started which is great if you have children in the vicinity. The handles also fold flat for storage, perfect if space is at a premium or you need to load it into the back of your car.

A generous 2 year warranty ensures your peace of mind.

The Mountfield Story 

Mountfield began manufacturing rotary lawnmowers at a premises in Maidenhead in 1962. The modern mowers today bear little resemblance but do still represent the same quality and value for money that the original mowers were built to.

Our lawnmowers have become part of family life for many of our customers, who have used our mowers for generations. They love our trademark reliability, performance and friendly customer service.



Your lawn is an extension of your home and the way you use it reflects the way you live. It could be a place for a bite to eat, relaxing with friends or family, your own mini Wembley or even your office space. Whatever your lifestyle, and however you use your lawn, you can rely on Mountfield lawn mower to create the lawn for you!


Mountfield have been one of the UK's best selling lawn mower brands since the 1960s. They’ve built a reputation for quality and reliability through their wide range of products. Mountfield first began manufacturing rotary lawn mowers in 1962 at their premises in Maidenhead, Berkshire. Despite the fact that today’s machines have very little resemblance to their ancestors, Mountfield garden machinery has always been made with high quality and good value for money in mind.

Mountfield aim to make gardening as pleasurable an experience as possible, and manufacture their products accordingly. Over the years they have continually developed their products to ensure they are both meeting and out-performing consumer expectations. Today they don’t just specialise in manufacturing of lawn mowers. They have a whole range of products to ensure that many gardening needs are met efficiently, from ride on mowers, to multi-tools and garden shredders.

Mountfield's lawn mower range is extensive. With hand pushed models, self propelled models, petrol, electric and cordless, there is something for just about everyone.

They produce 2 types of ride on mower; Lawn riders which are small enough to fit through a garden gate and a perfect choice for small to medium sized lawns and garden tractors for larger lawns. Mountfield’s hand-held range of garden machinery includes grass trimmers and brush cutters, hedge trimmers, leaf blowers, and chainsaws. They are all designed to be lightweight and easy to use. They are suitable for both domestic and professional users.

Mountfield have recently released their Freedom 48 range of cordless garden machinery. Once you have purchased a battery and a charger, you can use them for any of the product in the range as they all use the same battery.
