What Are The Benefits of Petrol Lawn Mowers?

There are three types of power your lawn mower can run on: petrol, corded (electric) and cordless (battery-powered), and all come with their pros and cons.

Petrol lawn mowers are generally much more powerful than their counterparts, which means faster completion times, and because they are mostly self-propelled, they are easy to start and to use. 

Because of their power, petrol lawn mowers are also more suited to cutting medium-to-large gardens, whereas cordless and corded mowers are better for smaller lawns. Petrol mowers aren't constrained by power cords either. 

How to Choose the Best Petrol Lawn Mower

These are some factors to consider when buying the best petrol mower to ensure you get the best value for your money and the most optimal machine for your garden. 

Size of lawn

This should be a primary consideration. Because the cutting widths of mowers will differ, some mowers will be more effective on larger gardens than on smaller gardens, and vice versa. 

Before you buy, make a rough estimation of how many square metres (sqm) of your lawn will need to be maintained: if your garden is between 50-150sqm then this is considered to be small to medium, while more than 150sqm is considered large.

How to start

The easier your mower is to start, the better. Keep a look out for machines that come with electric start or electric key starts, which are more time-efficient, but will cost more.

Self-propelled or push drive?

Self-propelled mowers are easier to work, making them suitable for large lawns and inclined areas. Because they propel themselves forward, you don't need to put as much time and effort into mowing - all you have to do is control the direction.

Push drive mowers don't have the control or ease of use, but they are generally much cheaper and well suited to smaller or medium-sized gardens. 

Collection

The larger your collection bag, the longer you can mow for. Therefore buying a mower with a larger bag (50L and larger is best) will prove valuable when mowing larger gardens. If you want to use your grass cuttings to fertilise your remaining gras then look out for a mower with mulching capability. 

How to Maintain Your Petrol Lawn Mower

Petrol lawn mowers require a certain level of maintenance, primarily through checking and changing the oil. It's best to do this as soon as you begin mowing in the summertime, and once a month throughout the summer. Always use the fuel and oil recommended by the engine manufacturer, and be sure to store your fuel in a sealed fuel can and keep it in a cool, dry, place.

You'll also need to clean your mower every so often to remove any grass or debris from the blades or underneath the mower. A small brush is handy for cleaning tighter spaces. An important note: make sure to completely switch off your lawn mower before cleaning. 

Lastly, it's beneficial to check your spark plugs every so often to ensure they don't become too dirty - every 25 hours is recommended, although an indication they need cleaning is that the lawn mower will be harder to start.
