Before each use of your mower you should check the oil level, this can be done with the lawnmowers dipstick. You also need to make sure you are using the right type of oil for your mower. If you find any discolouration, debris or the oil has turned a black colour then its better to completely drain the oil and replace it with a fresh one.

Keep it clean

Petrol Lawnmower FAQS

[amazon fields="B01MSUFU3U" value="thumb" image_size="large" image="6"]

Whats the difference between hand-propelled and self-propelled lawnmowers?

Self-propelled lawnmowers use power from the engine to power their movement, which are the best option for mowing large gardens and uneven lawns. Hand-propelled lawnmowers are often much cheaper but require you to push them and do most of the work, however this can be a good option if your garden is on the smaller side or has a lot of curves and flowerbeds, as hand-propelled means you will have greater control over your lawnmowers movement.

Whats the difference between mulching and rear discharge?

Mulching refers to a plug that you can insert on to your mower, this plug will chop the lawn clippings into extremely fine clippings, which will in turn then be blown down into your gardens soil acting as a great fertiliser. This saves you the pain of emptying your collector all the time and can speed up your mowing time. Mulching actually gives a lot of extra nutrients to your lawn and can stop you from having to buy extra fertiliser which tends to be not as natural!

Rear discharge refers to the same drop out of your clippings but doesn't chop up the clippings into fine pieces like the mulching blade does, which may mean you would need to this yourself.

What fuel do I use?

You should always use the recommended fuel for you specific lawnmower, most commonly unleaded petrol is used to power lawnmowers, however, you shouldn't use old fuel.

[amazon fields="B07C1YCXV7" value="thumb" image_size="large" image="6"]

How do I get those stripes on my lawn?

To have stripes on your lawn you need to use a lawnmower with a roller, the best lawnmower with a roller can be found here.

Whats better a two stroke engine or four stroke engine?

Four stroke engine's are the most popular engine in mowers that are currently on the market. Both engines perform similarly however the two stroke engine has a power rotation twice as much as the four stroke engine and requires a mix of oil and gasoline to power the lawnmower. Two stroke engines also tend be lighter and have twice the power of 4 stroke engines.

However 4 stroke engines tend to be a lot easier to use and start, and are overall a hardier option when it comes to mowing your lawn, 2 stroke engines tend to be less economical and release a lot of fumes too.

Electric or petrol?

The ultimate question is which one. Both type of lawnmowers have their advantages, with classic petrol mower proving a good option for hardier lawns and long term use, and electric mowers proving the better option for the environment by releasing no fuels and being much quieter meaning you can mow anytime of the day.

For a larger garden, petrol lawnmowers are a much more suitable option due to their extra power and often larger size. Electric lawnmowers tend to come a lot smaller which in turn means their cutting deck will be small too, meaning you would have to spend a longer time mowing your larger garden than you would with a petrol mower.

[amazon fields="B07N7VT3WT" value="thumb" image_size="large" image="1"]

Another factor to consider would be maintenance, both of the lawnmower types would require basic maintenance such as the sharpening of their blades. Petrol lawnmowers however need a little more attention such as; replacing spark plugs, checking oil levels, cleaning air filters and buying oil.

Overall, petrol lawnmowers are a winner if you have a more rural country garden that is on the larger side and needs a bit more power to get the job done. However if you have smaller home garden and aren't too fussed about its power, then the electric lawnmower would be a better option due to it being beneficial to the environment and also requiring much less maintenance.

What is OPC and why is it important?

Operator presence control is a must have safety feauture on a mower. It is a sensor in the handle of your mower, so if you let go suddenly or unexpectedly the lawnmower will automatically stop. This important so as your mower can prevent any accidents if you lose control of your lawnmower.

[amazon fields="B07N7VT3WT" value="thumb" image_size="large" image="2"]

What should I be checking before starting my mower for the first time?

Every time your start your mower you should be checking your oil and fuel levels, you should also check your spark plug when using your lawnmower for the first time, make sure it is not wet or has any debris. Depending on your lawnmower you should also press the fuel button a couple of times when starting your mower for the first time, this will pump any sitting petrol into the engine making start up much easier.
