Push mowers are the cheapest option and are ideal for flat gardens under half an acre. However, the ease of using a self propelled lawn mower is highly desirable as they push themselves with power usually being sent to the rear wheels.

The Engine

Petrol powered engines that are used in lawnmowers have improved massively over the years. Improvements include a reduction in fuel consumption, lower levels of noise and less emissions.

The majority of petrol engines will have a displacement between 100 cc and 200 cc. The larger engines will usually output additional power, which will allow you to effortlessly cut grass.

Cutting Width and Height

Grass Collection

Although not essential, most lawn mowers will come with a grass collection container. This is either constructed of a lightweight mesh material or a plastic container. Depending on the size of your garden, you will want to choose the appropriately sized grass collector.

If you prefer to not collect the cut grass, some lawn mowers have the functionality known as mulching. In short, the lawn mower cuts the grass even further into even smaller pieces, which is then outputted back onto the grass. This has the added benefit of keeping the grass green and healthy but also avoiding the task of emptying the grass collector.

Starting System

Some petrol engines have integrated an electric start button to get the the engine up and running. However, not every lawn mower will have this feature and they may use a recoil start system, which may not be suitable for some people.
