Your Buying Guide

Well-maintained grass adds to the appeal of a lawn. But these days there are so many lawnmowers available that it can be exceptionally hard to find something that suits your needs. Our quick guide offers you useful tips that will hopefully make the process of choosing a lawnmower less stressful and time-consuming.

Size and Weight

Choosing the right size and weight ensures that your body is not strained during mowing. These days, you can purchase a lawnmower which, besides giving you excellent performance, is also lightweight and smaller than the older models.

Push or Self-Propelled

A push lawnmover needs your physical strength to move forward. A self-propelled mower has the ability to move forward on its own, making it a good choice if you have slopes in your garden. Which one is best for you?

Engine Type

Generally speaking, all petrol lawn mowers come with either a 2 stroke, 3 strokes or a 4 stroke engine. It is not always necessary to go for a 4-stroke petrol lawn mower if a 2-stroke engine will still get the job done.


Q: How can I best maintain my petrol lawnmower to keep it functioning effectively for a long while?

A: Maintaining the petrol lawn mower is an excellent way to keep it functioning for a long while. However, the demands of maintenance vary from one petrol lawn mower to another. Timely maintenance which will mean you are cleaning both the interior and exterior parts can be beneficial.

Q: Are there safety precautions to adhere to when making use of a petrol lawnmower?

A: Yes, the petrol lawn mower is a grass cutting machine just like every other that requires safety precautions when using and storing it. These safety precautions include among others that you put on all protective clothing you need and keep children away from the machine.
