A higher cutting height is needed when your lawn doesn’t have optimum conditions, for example when there is extreme heat or cold, as a longer leaf allows it to stay healthy.
With a wider cutting width you will have to make less passes when mowing your lawn, reducing the time it takes. This is especially important if you have a large lawn.
With a mulching feature the grass cuttings are further cut into finely chopped grass which is then expelled onto the lawn, fertilising it and making it more drought resistant. This also means you do not have to empty a grass bag/box.
The cutting height ratio indicates the ratio between the minimum and maximum cutting heights, providing more versatility when choosing the optimum cutting length for your lawn.
A lower minimum cutting height is an advantage if you prefer a shorter grass length for your lawn. However, shorter grass requires good weather conditions to stay lush and green, such as warm weather and moderate sunlight.
