How to buy the best electric lawn mower

What should you be looking out for when investing in an electric lawn mower?

Corded or battery powered?

Electric lawn mowers are available both corded and battery powered. Corded lawn mowers are typically cheaper than battery powered lawn mowers, due to the hindrances of the electric cable; some corded electric lawn mowers may require an extension cable, and you need to make sure that the wire doesn’t get caught up in your prized hydrangea as you make your way round the garden. Due to their convenience, battery powered lawn mowers are more expensive, however, you will need to take into consideration charging time, power and how long the battery lasts in a single use. 

Power

Electric lawn mowers typically have a rotary blade, which makes them the ideal choice for long grass – great if you don’t have the time to be mowing your grass every weekend during the summer. To ensure it doesn’t make a hash out of trimming your grass, you’ll need to consider the power output. The power output for battery powered electric lawn mowers is typically lower than corded lawn mowers. 

Grass box

Aside from that, you may need to take into consideration the capacity of the grass box. Those with larger gardens should, naturally, go for a larger box, however 50L seems to be the generic capacity. If you want to cut out the middleman (the box), our second pick, the Flymo 1200R Lithium-Ion Robotic lawn mower cuts grass into the into minuscule pieces, so it can easily decompose back into the ground.
