An electric lawn mower is designed to be lightweight and easy to move around your garden. It offers enough power to manicure smaller yards, ensuring the grass is cut evenly. It is also cheaper and easier to maintain compared to a petrol model.
A petrol lawn mower is designed to be a workhorse suitable for both small and large gardens. It can handle cutting thicker grass and navigating through steeper terrains, making it suitable for heavy-duty garden tasks. However, it's more expensive and quite high maintenance.
