Best Mountfield Petrol Mowers UK 

By  Enda

Thanks for taking your time to read our information on the best Mountfield petrol lawn mowers, that are currently available on the UK market. Some UK buyers prefer to use the strength, power and flexibility of a petrol mower, rather than having to work with an electric lead, or a cordless mower.

People with larger gardens, professional landscapers and anyone with the love of an engine, will prefer to use a petrol mower.

How To Pick the Best Petrol Mower for Your Needs?

Mountfield make around 24 different models of petrol mower. Now while it is good to have choice, knowing which one to pick can get a bit confusing. Just below we have offered a few tips on how to quickly narrow down that selection.

There are 3 main features that you should really consider when buying a Mountfield petrol mower. Those are the cutting width, a hand propelled vs self-propelled mower and the type of engine and its size.

Size of Garden & Cutting Width

This is always the best place to start. It is very easy to quickly work out the size of your gardens. Simply pace out the approximate length and breadth of your gardens. (usually front, side and rear). A long pace is about a metre long so pace out the length of each garden and then the breadth.

As an example, my own rear garden is about 15 metres long and 7 metres in width. Multiply those 2 numbers together and you get 105 square metres. Then repeat that process for all your gardens and you will get an approximate square metre size.

Understanding the Cutting Width

All lawnmowers have a cutting width, and that can range in size from as low as 30cm (12") up to around 53 cm(21")

So, if you push your mower down one length of your garden, the cutting width is the width of grass your mower will actually cut. A mower with a 39 cm cutting width for example, will cut 39cm of grass, so to cover a metre will take 3 passes of your mower.

The easiest way to remember this is that the wider the cutting width, the less number of passes you will have to do, and the quicker you will get your grass cut.

Hand Propelled vs Self Propelled

Hand propelled mowers are easier to manoeuvre, can be moved at your walking speed and also give you a little bit of exercise. They are always going to be a cheaper option than a self-propelled option.

Self-propelled mowers are a much better option for larger gardens, or gardens with slopes. They use gears to drive the mower forwards and simply take less effort to use. They are slightly more difficult to control, but once you get used to the way they work, they are very simple to use.

It really is a matter of choice and a personal one at that. For a flat medium sized lawn, and as long as you are reasonably fit and healthy, then a hand mower is a good choice. For larger gardens or those with slopes, we would recommend the self-propelled option, though do bear in mind that will be more expensive.

Engine Size

Honestly, if you ask 1,000 people which is the best engine size for a mower, you will get a whole variety of answers. The better question to ask yourself is, "which engine is best for me?"

The things you should really consider is the garden size which we have explained above, the shape of your garden including any slopes, the starting system and the level of maintenance they will require. Our strong advice would be to buy the best engine size that you can afford.

Most of us don't need an engine powerful enough to cut a football pitch or a cricket pitch. Something like a 123 cc engine is powerful enough for most people.

Also remember that all petrol mowers need maintenance with reference to oil levels, oil filters, spark plugs, the drive mechanism on self propelled mowers, and then general maintenance of the blade and making sure the underside of the deck is cleaned.

Hand Propelled Lawn Mowers

The main differences in these mowers is the cutting width, the engine type and what the actual deck is made from. That is what will change the price point. The two most popular hand propelled Mountfield mowers are the HP45 and the HP 185.

Other Features to Consider

Hopefully you have now got a better idea of the many Mountfield mower options available. So far, you may already have noticed that, the main difference is really between the mower being hand propelled or self-propelled and the actual cutting width, and type of engine.

There are however other considerations and features that you may also want to consider, and we have explained those just below.

Decking Construction

The decking on a mower is basically the lower part of the mower where the blades are housed. To keep mowers lighter and also to make them cheaper, plastic is often used. It is a tough plastic and usually it is polypropylene. This is a thermoplastic polymer used in a wide variety of applications such as bottle tops, bottles, pipes etc.

It is mainly used for plastic mouldings as it is tough enough and yet has some movement in it.

Some Mountfield mowers use this material for the decking. However, the slightly better made ones use steel as it is simply tougher and stronger. It does of course make the mower heavier, but adds to the overall quality of the mower.

The Mulching Plug

When people mow their lawns, the grass is typically collected in a grass box or a grass bag attached to the lawnmower. This can then be emptied into a recycling bin, or put onto a compost heap to make compost.

However, many experienced gardeners understand, that sometimes it is better to not collect the grass, and allow the small trimmings to remain on the lawn. These can act as a natural mulch, and help protect your lawn, retain moisture and improve its overall quality.

Good quality mowers have what is called a mulching plug to achieve this. Instead of attaching the grass box, you insert the mulching plug, and this pushes the cuttings downwards into the lawn. Some will do this by pushing them out the front of the mower, and others push the cuttings out of the rear of the mower.

Hopefully the above information will help you out if you are considering a petrol mower from the Mountfield brand. These are good high quality mowers, that work really well and are built to last.


I am someone who enjoys a little gardening. Now I am not someone who spend hours in the garden, but I do like both my front and back gardens to look really nice. Well kept lawns, neatly trimmed hedges, and borders filled with plants, make a huge difference, to how your property looks.
