How to Choose the Right Petrol Lawn Mower

Before buying a petrol lawn mower, it is worth thinking about the size of your garden, the type of terrain you mow and how much effort you want to put into regular lawn care.

Lawn Size

Small gardens
Lightweight push mowers or compact self-propelled models are usually the easiest to manoeuvre and store.

Medium gardens
A standard self-propelled petrol mower offers a good balance of power, comfort and efficiency for regular mowing.

Large gardens
For larger lawns, it is worth choosing a mower with a wider cutting deck and a more powerful engine to reduce mowing time.

Self-Propelled vs Push Mowers

Self-propelled petrol mowers are a popular choice for UK gardens because they require less effort to use, especially on uneven ground or slopes.

They are ideal if:

• Your garden includes hills or uneven areas
• You want to reduce physical effort
• You regularly mow larger sections of lawn

Cutting Width

A wider cutting width helps cover more ground with each pass, making mowing quicker and more efficient on medium and large gardens.

Smaller cutting widths can still be useful for tighter spaces or more complex garden layouts.
