Mountfield HP185 Review

The Mountfield HP185 petrol lawn mower is powered by a 125cc Briggs & Stratton 300 Series engine and has a 46cm cutting width suitable for medium sized lawns. This petrol mower comes supplied with a 60 L grass collection bag and has 3 cutting options that include Cut and Collect, Mulch and Rear Discharge. The 26 kg mower offers 6 cutting heights from 22mm to 65mm and is operated by a single lever to the rear of the mower.

Mountfield has been in the business for almost 100 years, so when you purchase any of their products, you can feel confident that you are getting something that has been manufactured with experience and to a high standard.

This is perfectly demonstrated in this petrol rotary lawn mower that comes in a striking red colour; if you like your garden equipment to mimic your personality, this is undoubtedly a good choice. But aside from looking the part, this Mountfield HP185 mower has plenty to offer anyone with a medium to large garden.

Primarily, you notice the wide 46cm cutting width and the six cutting heights, which are extremely easy to adjust with the single lever – no more messing about with multiple levers. Furthermore, this mower has a great range of mowing functions so you can cut the lawn in a way that suits you and with a huge grass collection bag, your mowing time won’t be interrupted.

If you’re looking for a self-propelled lawn mower, then this one doesn’t provide that feature; however, there is another version that does have a self-propelled drive, and a good one at that; the Mountfield SP185.

There are a lot of good things to say about this piece of garden equipment, so let’s dive in and take a closer look at this Mountfield HP185 petrol mower.

Mountfield HP185 Engine

If you are looking for a powerful lawn mower then you won’t go far wrong with this. It is fitted with a superb Briggs and Stratton 300 series engine that boasts 125cc of power. Briggs and Stratton have been making engines for a significant period of time, and this leaves you safe in the knowledge that the quality will be nothing short of incredible.

What’s more, this Mountfield HP185 is easy to start; we all know how difficult some petrol mowers can be to get going, but you won’t have any problems with this one.


Owing to the excellent engine, you will get overall brilliant performance out of this mower and thanks to the wide cutting width, it will make light work of most medium to large-sized gardens.

Oh and did I mention that the mulching plug comes supplied with this lawn mower? It is an optional extra with some other brands, if an option at all.

Self-Propelled Drive

This Mountfield HP185 lawn mower is a hand-propelled machine and is denoted by the HP in the model number. However, if you want to benefit from all the features and the power that this piece of equipment boasts, but also want the addition of self-propelled drive, there is another option. The Mountfield SP185 is the same mower, but in addition is provided with what some users would class as all-important self-propelled drive.

Blade And Deck

Mountfield HP185 Deck

This is a rotary petrol lawn mower with a strong steel blade measuring 46cm. Furthermore, the durable steel deck makes this a robust piece of equipment that is guaranteed to stand the test of time; and if it doesn’t, you’re covered by a lengthy two-year warranty (providing peace of mind).

Cutting Diameter

With this Mountfield HP185 petrol mower, you are getting a generous cutting diameter of 46cm. This is perfect for more extensive lawns and will give you far more coverage in each pass. Couple this with some of the other handy features and you have an excellent petrol lawn mower for a decent-sized lawn.


Having a comfortable handle on your lawn mower is essential for a pleasant user experience and to help absorb vibration. Fortunately, Mountfield appears to have covered all bases where this is concerned.

The ergonomically designed handle provides you with easy access to the starting mechanism, which will shut off as soon as it is released. Furthermore, the handle is fitted with a folding mechanism so that storing the lawn mower is a lot more convenient.

Height Adjustment

Mountfield HP185 Height Adjustment

Throughout the year, you are likely to have the need to cut the lawn to different lengths to keep it healthy, and in some cases, this can be challenging since many mowers come with a dual lever height adjustment that is tricky to alter.

In contrast, the Mountfield HP185 features a single lever height adjustment system that allows you to alter the cutting height in seconds. What’s more, there are six heights to choose from ranging between 22mm and 65mm, making this a diverse piece of equipment, suitable for year-round use.

Mowing Features

With this lawn mower you are not only getting power but also versatility. Having the option to cut the grass in a manner that suits you is so important, and with three mowing methods to choose from, you are spoilt for choice.

There is the traditional grass bag collection method which allows you to collect the grass clippings and dispose of them easily, or there is a rear discharge which is great for rougher ground. Finally, there is a mulching plug included in the box, allowing you to return the grass clippings back to the lawn.


As I have mentioned, you are getting a mulching plug included with this Mountfield HP185 model, and this means that as you trim the lawn, the grass cuttings are returned back to it and will act as a free organic fertiliser.

Grass Box

The grass box that comes with this model is extremely generous. With a 60-litre capacity, you certainly won’t be running out of space in there quickly. This is great for those bigger gardens as it will prevent you from having to stop and make a trip to empty the bag as often as you would with a less substantial collection bag.

Safety Features

Thanks to the control, which is located on the handle, you are easily able to start and stop the lawn mower. This means that as soon as this is released, the blade will stop making this a safe piece of equipment to use.


Mountfield HP185 Practicalities

One of the best things about this Mountfield HP185 petrol lawn mower, practically speaking, is its simplicity, engine performance, reliability, low maintenance and its anti-scalping plate. Thanks to the anti-scalping plate, that was not featured on the older model, you won’t inadvertently scalp your lawn particularly on uneven surfaces i.e. where there are humps or bumps in the lawn.

Furthermore, with a two-year warranty, you can feel confident that you won’t be left stranded should anything go wrong. But what is even greater is that along with your purchase, you will get after sales support from none other than ServiceLink, which is an experienced garden machine repair specialist.

This is an exceptionally easy to use piece of equipment so even if this is your first experience in using a petrol mower, you won’t struggle.

It also features four stable wheels meaning that even when you are using the mower on less smooth ground, you won’t notice a drastic change in terrain and will still get a good cut.
