One of the biggest mistakes you can make when buying a new lawnmower is to buy one because it has the most power and the biggest motor. If you have a small lawn and buy a lawnmower with a large motor, it is likely that you will never get to use the lawnmower to its full potential.
Instead of using the power as a guide as to which lawnmower to purchase, look at the size of the collection box. This will often indicate the size of the garden they are built for. A bigger grass box often means that it is suitable for a bigger garden. If your lawn would never fill the grass box, then it’s probably not the correct lawnmower for you.
