Plug in the mower and push it up and down the garden. If that was all there was too mowing the lawn we would all have gardens that looked like the middle of Lords Cricket Ground. But, most of us have scrappy patches of earth with grass that looks a long way from beautiful. That is because mowing is part art and part science, but mostly effort.
If you want stripes you need a lawnmower with a roller at the back. Hover mowers simply do not cut the lawn in the same way and will never deliver stripes.
Having said that, hover mowers are very easy to use. Because they are so easy to use you are likely to pull them out of the shed more regularly and actually end up with a better looking lawn than someone using a traditional rotary mower.
If you have a larger lawn then you might want something with a bit more poke, but be warned that the popular Even petrol driven rotary mowers are also a bad choice if you want that cricket pitch or bowling green look. That said, if you just want a nice looking lawn then they are great. If you have a really big lawn then consider a stand on mower which are a lot less effort than a push along.
Which ever type of mower you have, the regularity of cutting the grass is actually the most important thing. Approximately twice a week during the growing season is the consensus view.
Once the temperature dips below 9 degrees centigrade the grass stops going and shuts down most of its metabolic processes. This means no mowing needed, but also means you should avoid walking on it during the winter. If you do walk on the grass at this time you may find that the damage you do takes a very long time to repair itself.
