Flymo Mighti-Mo Li 300 Review

Flymo Mighti-Mo 300 Li Cordless Battery Lawn mower, 40 V

The Flymo Mighti-Mo 300 L Cordless Battery lawn mower is one of the best selling cordless lawn mowers in the UK, but is it all what it’s cracked up to be?

The 300 is indeed packed with features found in more higher end cordless mowers and certainly has the ability to cut a lawn up to 250 meter square (roughly the size of a tennis court) , but it needs to be compared to it’s nearest rival, the WORX WG779E, to judge how good this mower really is.

To compare Flymo Mighti-Mo 300 to other cordless mowers in higher or lower price range would distort the results, these two mowers are probably the most affordable and best performing 40v cordless mowers on the market today.

Below I’ll be detailing all the features and functions of the Flymo Mighti-Mo 300, both good and not so good and then comparing to the WORX WG779E so you understand exactly what you’re getting for your money.

Power System

Like many cordless lawn mowers, the Flymo Mighti-Mo 300 is powered by a Lithium-ion battery (40V) and electrical motor which it will charge in around 2 hours. The battery is removed from the mower for charging and storage.Mighti Mo 300 Li Battery

There is a downside however.

For each time this battery needs to be charged, it could take up to 2 hours to fully recharge and will only produce a mowing time of around 25 minutes. In comparison the WORX WG779E.2 takes a shorter 1.5 hours to charge and will last longer with the ability to cut a lawn up to 350 m². This is surprising as the Flymo Mighti-Mo 300 weighs 3 kg less that the WG779E.2. Worx introduced the two 20v batteries in 2018 to enable compatibility with their other cordless power tools of witch there are 40 in the range. The two Worx batteries can be charged at the same time and the Worx WG779E.2 comes with an eco mode for lighter cuts, reducing the power and extending the cutting time.

This ratio isn’t great and is an aspect which its competition actually betters it. But in saying that the mowing/charging time doesn’t directly affect you, after all the lawn will still be getting mowed!

Also the power system is completely electric so it produces zero emissions and works extremely quietly. Which is quieter? well there’s not much between them but would say the WORX is slightly quieter due to the “Mute technology” that WORX claim makes there mower barely audible from 10m.

The great thing about these mowers is that you can set out to work at any time you want without it annoying you, your family or your neighbours, and with zero emissions look after the environment as well.

Blades

The Flymo Mighti-Mo 300 is equipped with one FLY069 30cm Wheeled metal mower blade that gives them two very effective benefits…FLY069 30cm Wheeled Mower Blade

  1. Metal blade generally wear less quickly than plastic blades which results in you needing to replace the lawnmower blades more often than a lawnmower that uses a metal blade.
  2. Metal blades are generally sharper and provide a cleaner cut to the grass blade, resulting in a neater, tidier and superior finish to your lawn and garden. The metal blades on the 300 can be sharpened when needed unlike plastic blades.

This again does not necessarily put it ahead of competitors but it’s good that Flymo have taken advantage of what is clearly the most effective cutting system in the market.

Height Adjustment

In order to combat the changing season and to continually improve the look of your lawn, you can adjust the height at which the Flymo Mighti-Mo 300 cuts at. This is done very easily using the large lever located on top/side of the mower.

Flymo Mighti-Mo 300 Height

It lets you choose to cut from anywhere between 25mm to 65mm with 5 separate cutting lengths. Just make sure you don’t set it at the shortest setting from the when the lawn has significant growth, instead start at a much higher setting and gradually work your way down. This gives the areas of small grass to catch up with the long, resulting in a more even garden.

As well as being able to sharpen the blades, it is also possible to purchase a replacement blade. Replacing the blade is relatively easy for anyone with basic DIY skills and tools.

Cutting Diameter and Height

The cutting diameter of the mower may seem a little on the small size with only a 30cm mowing capability. Now, compared to it’s counterparts with widths of up to 43cm, this might be a potential disadvantage; however, it could also be beneficial if it’s to be used in a smaller areas and lawns with narrow strips.

When you need a mower that’s light in weigh and going to get in the smaller areas of your lawn, this may well be the best option. Yes it will take longer to mow the entire area, but if it fits, and hey there’s no rush then the Flymo Mighti-Mo Li 300 could be the cordless  mower of choice.


Grass box capacityFlymo Mighti-Mo 300 Box

As with all smaller cordless lawn mowers the grass box is not going to hold as much it’s larger counterparts, however 30 litres is a comparable for a mower of this size. 30 Litres allows longer periods of use without needing to empty grass clipping as often.

The grass box on the Flymo Mighti-Mo Li 300 is very easy to remove and the grass clipping empty from the box with no obstructions.


Practicalities

The light weight, small size and fold away handles make this mower excellent for smaller lawns or lawns with smaller strips of grass.

Mighti Mo 300 Li HandleThis really will make lawn care much easier and really makes the entire experience much less dependent on you struggling with a heavy over sized mower.

As with all cordless lawn mowers, not being tethered by the cord not only make it easier to mow the lawn, but safer, quieter and more environmentally friendly.

Does this make it more practical the it’s closest  competition? well, yes I think it does for people with smaller lawns and limited space for storage. There is also a very handy and well positioned central handle that makes carrying the almost 10 kg  mower to the garage or shed very easy.


Safety Features

What I really like about the Flymo Mighti-Mo Li 300 is the addition of a removable safety key that disables the lawnmower to help prevent accidental starting. This is a nice feature not found on similar cordless mowers that give peace of mind around children.


Mulching

As with most cordless lawn mowers in this class and at this price range, there is no mulching facility with this Flymo.


What’s Included in the box?

  • The mower itself
  • 1 x Lithium-ion battery (40V)
  • 1 x 30 Lt grass box

Downsides

  1. This mower does take a long time to charge, some competitors can charge much quicker and still produce the same working time. But this doesn’t affect you too much so you needn’t worry about this.
  2. There is no battery gauge to show the charge level.
  3. There is no grass box level indicator as with some of the other models such as the WORX WG776E.

Now the above may sound trivial and are common to most cordless mowers but should be taken into consideration anyway. They are part of the package and it’s better being aware of them before a purchase than after.

FLY069 30cm Wheeled Mower FoldedConclusion

Overall this is a very good mower, I actually rate it higher than the Spear & Jackson 37cm Cordless Rotary Lawnmower due to it’s light weight, portability and good build quality.

The extra features like the removable safety key is a nice touch but one that you most probably never use, besides you want features that will help achieve a lovely looking lawn with least amount of work and effort.

The Flymo Mighti-Mo Li 300 is very proficient at cutting varying lengths and thickness for such a small and compact cordless mower. It’s worth mentioning that by cutting more regularly and avoiding very long or wet grass this should avoid not putting too much strain on the battery. Remember to always keep the battery charged and in a dry place over winter.

With this mower you’re getting features normally found in high priced mowers, so this is a very reasonable price at under £200.

But do I think it’s better than its closest competitors?

Yes I do!

At this price range (less than £200) this really gives great value for money and you would be very hard pressed to find a cordless mower that performs this well, and has such a good build quality for this price. To get the best out of this mower you will need to cut your lawn more regularly and not let the grass grow too high or dense as it will struggle to cut it, this is however common with all cordless mowers at this price point and specification.

Overall I think this is a fantastic mower and I encourage everyone with a garden under 250 m² to purchase one. In fact I think it’s the best mower at this level you can get right now!


Should You Buy This Model?

Well there are a few factors to consider first, whether or not you purchase this model really depends on your garden and situation.

To give you some guidance on which type of customer would suit this model best, below I’ve got a list of the categories they would fall under:

  • Their garden is about 250 m² in size
  • Like the convenience of having no power cord or have limited or no access to a power source in the garden
  • Their garden is split up into different areas, with smaller strips of lawn
  • They don’t mind cutting the lawn regularly and not allow the lawn to grow too high
  • Storage is limited
  • Do not want to spend £250 plus on a mower

Of course this is open to interpretation so if you don’t fall under every single one then don’t worry I’m sure you’ll still love this product. It has loads of great features that I’m sure you make use of even if you’re not its perfect customer.
