Choosing a cordless lawn mower
There are numerous models on the market to choose from but the most important specification you need to know about is cutting deck width. This is basically the width of the blade and it determines the size of the lawn the mower is best suited to.
If your urban lawn is of average city size (about 40 meters² and up), then go for a 33-36cm deck, and if it’s of the medium-sized suburban variety (in excess of 100 meters²) then opt for a larger model with a deck of around 40cm and upwards.
That said, some urban lawns are nearer to patio size so the smaller the cutting deck the better. In this regard, a titchy mower with a cutting deck width of just 30cm will likely suffice.
Some buyers of lawnmowers are easily taken in by the voltage power of the battery but we’ve found that most small lawn mowers perform admirably well even when armed with lower voltage batteries.
It’s only when lawn size gets to around 300meters² that you need to start considering some of the higher-end cordless models that come with huge 60v and 80v batteries.
These models usually have cutting decks in excess of 50cm in width and some of the flashiest models from the likes of Greenworks and Ego even feature self propulsion for effortless mowing.
