Flymo is one of the top selling lawn mower manufacturers in the UK, best known for inventing the innovative hover lawn mower that remains popular today. However, the company are known for manufacturing all kinds of mowers, including cordless rotary mowers such as the Flymo Might-Mo 300 Li.
Ideal for your average size UK lawn (around 250m2), the Might-Mo 300 Li also offers the convenience of cordless operation, being powered by a robust 40V lithium-ion battery. With a good runtime, varied cutting heights, and a lighter weight, this mower is a good option for most buyers seeking reliable cordless operation for a reasonable price.

Battery and Motor
The Might-Mo 300 Li is equipped with a large 40V 2Ah battery to power its electric motor. This provides a decent runtime of around 25 minutes or so, with slight variations depending on conditions.
This runtime makes the Might-Mo 300 Li suitable for most average UK lawns, which is around 250m2, although it works perfectly fine on lawns smaller than this too. Anything larger may require a second battery to finish mowing.
Charging takes longer than some other cordless mowers, with the 2 hour charge time being on the higher side, although given the lower price point this does make some sense.
A good option to avoid issues with the battery running out too soon is to buy a secondary battery, ensuring one is always charged and ready to use so you don’t need to wait several hours to charge – this also doubles runtime so is a good idea if your lawn is on the larger side.
As this mower is cheaper than a lot of others, the cost of adding a second battery should not hurt your wallet too much!
Fitted with a 30cm steel cutting blade, the cutting width of the mower is suitable for most medium size lawns, while being a good choice for smaller lawns, mowing a sizeable portion of the lawn with each pass.
If using on smaller lawns you can expect even faster mowing times, and due to the compact design of the mower it is easy to turn it around on narrower lawns.
The blade is high quality, as with every Flymo mower, producing a clean cut across the grass to leave a nice finish while encouraging healthy regrowth and avoiding scalping. It is removable too, so you can sharpen the blade should it start to dull, although this is unlikely for several years at least.
There are 5 cutting heights available with the Might-Mo 300 Li, ranging from 25mm to 65mm, which are adjusted using the central lever on the deck. This is the perfect selection of cutting heights, offering low and hight settings that allow you to get the right cut depending on the length and condition of the lawn.
For instance, 25mm is close to the ground so great for achieving a close cut. This is good for summer mowing when you are mowing twice a week and want to remove small amounts more frequently.
On the other hand the higher settings are good for when you want to leave grass a bit longer, such as after the first cut of the season or the grass length is longer than usual and you don’t want to remove too much.
In any case, these settings are suitable for any gardener, whether you mow frequently to get the perfect lawn or mow less often.
As mentioned, the Might-Mo 300 Li is lightweight, weighing just 9.94kg. This makes is one of the lightest cordless mowers available, so manoeuvring around the lawn is almost effortless. Not only is this great for sloped lawns, but also for any gardener that requires something lightweight and easy to operate.
The large wheels also make it easy to operate around the garden, being large enough to offer the right amount of stability without feeling too heavy or cumbersome. These wheels can make it through longer grass easily enough without getting stuck.
A dual handle design means you can power the mower with one or two hands, although the handle itself cannot be adjusted to different heights and angles. Adjusting the cutting blade is quick and easy too as there is a central lever on the left side of the mower deck – just move it o the desired setting and the blade height adjusts accordingly.
Of course, as a cordless mower there is no power cable restricting your movement, allowing for flexible operation throughout the garden. This is especially useful in gardens where lawns are further away from your property or awkwardly shaped.
Grass Box and Storage
While there is not much included beyond the basic features, the Might-Mo 300 Li does come with a sizeable 30L grass box to gather clippings. This is a large capacity that should provide enough space for clippings on average size UK lawns without needing to empty it until you are finished, saving you time.
The Might-Mo 300 Li is naturally compact but the handles also folded down, converting the mower into an even smaller size, allowing for easier storage in sheds and garages.
There is no mulching or rear roller features included, although for such a good price point it is hard to feel the product is lacking too much.
