The best lawn mower: Electric, manual and petrol

Rediscover the joy of mowing with our expert Buyer’s Guide

Man mowing the grass with a manual petrol lawnmower.

by Piper Huxley |

Regular mowing is essential to having the best-looking lawn around. And keeping it that way. Our advice is to mow at least once a week in spring and summer, and less regularly in autumn and winter. So, Geoff Hodge from Garden Answers has helped us pop together a guide to the best lawn mowers for your garden – to keep your grass in tip-top shape.

What types of lawnmowers are there?

A manual push-along cylinder mower might conjure up images of lazy, hazy British summers, but they’re not a quick or easy option - unless you have a tiny lawn.

Most lawns are best cut with a rotary blade. Most of these are rechargeable mowers and powered by lithium-ion batteries - offering the best solution. Not only are they light, but they are easy to manoeuvre. So, you don’t have the drawback of a trailing cable, and their motors don’t require any maintenance nor produce any emissions.

On battery lawnmowers, Geoff Hodge says: "As we get more used to charging battery-powered cars, battery lawnmowers will become an easy choice. What’s more, their batteries can often be shared among sister products in the same range."

What to look for in a lawnmower?

Deck Material - Strong, robust metal decks add to the overall weight. Non-metal decks, usually made from polypropylene, are lightweight, damage resistant and resilient

Comfort Handles - Soft, comfortable and height-adjustable handles make mowing easier on your back and hands, especially when cutting for a long time.

Carry Handles - Well-spaced carry handles make the machine balanced, lighter and easier to carry.

Blade Height Adjuster - This needs to be easy to adjust and offer a choice of cutting heights. Most lawns should be cut 2.5-4cm (1-1½in) high for much of the year.

Clippings Collection - Grass collectors cut down the time needed to look after the lawn. Larger collectors need emptying less regularly.

Grass Combs - Side grass combs help ensure neat results along edges, fences, and walls.

Rear Roller –This is needed if you want traditional lawn stripes. The heavier the machine and roller, the better the stripes.

Mulching Function - Some mowers cut the grass so finely, that you can leave the clippings where they fall.

The grass height lever is easy to move. The lowest setting is too low, you need a pristine flat lawn, with no lumps. The next one up works ok but leaves some daisies. It is very easy to manoeuvre around the garden, very light but a bit heavier to lift into my shed. I’m very pleased I bought this mower and would recommend it."

Customer Review: "I have been a fan of Honda mowers for many years, my last Honda mower lasted 14 years! My new mower arrived today, a week early, and for which I was very grateful. I quickly unpacked it, checked the oil and filled it with petrol. I then set about putting the grass catcher together. This was a real pain but, eventually, I got there. My other whinge is that there is no handle on the grass catcher making it clumsy to take off and put on. Still, not a major problem. The mower started on the first pull and I was very pleased with the results. My thanks to the supplier for the speed with which my new mower was delivered and I look forward to many happy years of grass cutting."

Cons: Mostly plastic

Customer Review: "I wanted a mower that was easy to start - not temperamental like my petrol mower - easy to maintain and look after. I love everything about this mower, it is extremely well-made and is a very robust construction. My lawn is approx 300sq yds and I reckon I could have cut it twice over even with the self-propelled option engaged. The battery and charger claimed to be the best on the market, my experience would suggest it probably is both, in power 56v and 5ah, and fan cooled charger that charged it in about 40mins from fully discharged.

"It has all the useful features you would require such as an adjustable handle, large grass box, seven cutting heights, variable automatic cutting speed and variable self-propelled speed control. It can also be stored on its end so takes up very little room to store. I cannot express how impressed I am with this mower and haven’t hesitated in giving it five stars. If you are looking for a battery-powered mower that can do the job easily, then look no further; this is the mower for you."

The mower was easy to assemble. It is light and very easy to manoeuvre. My lawn area is about 185 sq m. I have been able to cut it three times on one charge of the battery.

Cutting Width: 33cm

Grass Collector Capacity: 35L

Cutting Heights: Five, 2.5-6.5cm

Pros: Quiet, Lovely Cut

Cons: Too Lightweight

Customer Review: "This is a mower for small gardens: it is not a heavy-duty one for intensive or difficult cutting. But it is excellent at what it is designed for cutting small gardens with minimal effort. It is extremely light & easy to use: it may not be as efficient as a mains or petrol mower, but the ease of use of a cordless mower more than makes up for it. Just don't expect it to be as efficient. The 2.5ah battery only lasts for about 75 sqm: for grass larger than about 50 sqm you really need the 5.0ah battery, especially if the grass is longer than usual. When assembling, be careful: it is easy to assemble the arms the wrong way round."

What’s the difference between a push and a power mower?

Gardens expert Geoff Hodge says: "One recent development in the world of battery-powered lawnmowers is the introduction of self-propelled mowers – previously only available with top-of-the-range petrol models. Self-propulsion makes mowing easier and more manageable because the mower pulls itself along, reducing effort and fatigue.

"Self-propelled lawn mowers are perfect for larger lawns and slopes. You simply walk behind the mower to control its direction. Because power is needed for this, the batteries won’t last as long from a single charge as those used with an equivalent push mower."

What do I need to know about battery lawn mowers?

With battery power, you need to consider: the battery voltage (V) and amp hours (Ah).

Voltage - Higher voltage generally means greater power and performance, but the size and weight of the mower will impact this, too. Mowers with a higher voltage are better equipped to tackle long, wet grass.

Amp Hour - This is analogous to the size of a car’s fuel tank; the larger the amp hours, the longer the battery will last between charges. Higher Ah batteries can tackle larger lawns before becoming flat. For instance, a 2.5Ah battery should cut up to 400sq m (480sq yd) on a single charge. However, more amp hours do not equate to greater power output.

Lithium-ion batteries charge relatively quickly – in as little as 30-40 minutes. Depending on Ah size, they’ll run long enough on one charge to complete mowing. They can be recharged before they’re flat and don’t need to be fully charged before use. Plus, they won’t lose charge in the shed over winter.

Geoff also recommends buying a second battery "if you want to mow a large lawn in one session".

Some mowers come with two, while others offer super-fast chargers. Mowers with the latest sensory technology can sense the load on the motor and operate at the optimum level for each task, boosting power for long/damp grass and extending battery run time during lighter cutting tasks.

What is cutting width?

Broader mowers tend to offer greater cutting width. A larger mower, with wider cutting width, reduces the number of passes needed to mow the lawn but may be heavier to carry and more awkward to manoeuvre.

As a guide:

Small lawn (up to 250sq m/300sq yd): 30-35cm (12-14in) cut width.

Medium lawn (250-580sq m/300-700sq yd): 35-43cm (14-17in) cut width.

Large lawn (more than 580sq m/700sq yd): 43-55cm (17-22in) cut width.
