Petrol lawn Mower Buying Guide

Your choice of lawnmower will, of course, depend on your particular needs. Here are a few things to consider when choosing the best petrol lawnmower for your garden.

Manual push or self-propelled

A self-propelled lawnmower uses the engine power to power the forward motion rather than you having to push it. This is great if you have a large area to mow or have uneven lawns or slopes. They also make light work of long grass, tussocky grass and damp grass. This type of mower will require a larger engine and with be more expensive, though. It may also make the mower heavier and larger to store.

A push mower will be adequate if you have a flat even lawn and rarely have to cut long overgrown areas. The blades are powered by the petrol engine but the mower is hand pushed rather than being propelled by the engine. These mowers are usually smaller and lighter and offer great manoeuvrability in small to medium gardens, especially when using them around flower beds and features.

Petrol lawnmower maintenance

A petrol lawnmower will last you may years, however, it may occasionally require repairs. Check that the brand you choose has spare parts available. Your lawnmower will also need regular servicing to keep it working well for years. You can do this yourself or have someone do it for you. Many lawnmowers offer a 3-year guarantee, so this is worth looking out for.

Features to look out for:

The size and quality of the engine is key to a good mower. Choose a reliable brand and make sure it is powerful enough for the job at hand. Remember self-propelled machines will require more power.

Size of mower

The size of the cutting deck affects how much grass gets cut at a time. A smaller deck will be suitable for smaller gardens, especially if there are features to mow around. For large gardens, a larger deck will get the job done more quickly.

Starting options

Some mowers have an electric key start for a reliable start every time. These machines have a rechargeable battery to provide the starting mechanism, so you will have to remember to charge this. Most also have a standard pull start as well in case you don’t have the battery charged.

Other machines have an automatic choke for reliable starting. Some models are started by priming and pulling, this means pressing a priming bulb slowly three times to deliver fuel to the carburettor and then pulling the starting cord.

Size of clipping bag

Stopping to empty the clipping bag can be a nuisance. If you plan on collecting clippings, then choose a mower with a larger bag to cut down the time spent emptying.

Variety of cutting settings

Mowers have a variety of cutting heights usually measured in millimetres. These vary a little and some machines cut lower than others, so check this if you want a bowling green finish to your lawn. Most are adjustable with a simple lever but some are more complicated to use.

Cleaning and mulching abilities

Additional features include mulching accessories and cleaning accessories. A mulching accessory will shred the clippings into tiny pieces before discharging them onto your lawn. This helps to fertilise your lawn and maintain moisture. This is an especially good feature if you often cut long grass that would go sodden and brown if left on the lawn. A hose attachment makes light work of cleaning your mower which is essential if you are going to get many years of use out of your machine.


I have recently purchased a petrol lawnmower. How do I use and maintain it to make sure it gives me many years of use?

There are several steps to using and maintaining your lawnmower. The following are highly recommended maintenance tasks that will keep your mower running and cutting well for years. You can undertake routine servicing such as filter and oil changes yourself or take your machine into a dealer. Booking your service at the end of the season is a good idea as dealers can be very busy in spring.


Always use the fuel recommended by the manufacturer and ensure it is fresh. Unleaded petrol goes stale after three months and this may make your mower more difficult to start.

Check the oil level before every use and top up if necessary.

Cleaning and checking the mower

Check all bolts and screws regularly to make sure they are not loose or missing. Check the wheels to make sure they are not loose or wobbly.

Clean the underside of the mower after each use as grass left on the metal parts can cause acids which may damage them. When cleaning and checking the machine deck always lift it up from the front. Turning the mower on its side can allow fuel to flow into the air filter which will cause difficulty in starting and excessive smoking.

Clean the cutting blades of your machine regularly and have them sharpened or replace them as necessary.

Clean the grass bag or box because if this becomes clogged it may block air flow or cause poor collection.

If your mower is self-propelled check the drive belt regularly. Take off the belt cover, remove grass and debris and check that the drive belt is in good order and properly adjusted.

Routine servicing

Check the air filter and spark plugs and clean or replace if necessary.

Change the oil.

Winter storage

At the end of the mowing season drain the fuel from the tank or run the engine to burn off any remaining fuel.

Always store the mower on a level surface. Do no lean it against a wall or hang it from a hook as this may cause oil to seep to unwanted parts of the engine.
