Mountfield Electress 30 Li Kit (30cm, 20V 4Ah)

How long does the battery last on a single charge?

The included STIGA ePower 20V 4Ah lithium-ion battery gives you up to 20 minutes of run time per charge. That sounds short on paper but most owners report getting through small to medium lawns without issue.

One reviewer mowed a 90 square metre back garden and a 60 square metre front garden and still had three out of four charge bars left. Charging from flat takes around one hour, so you can usually fit in a few short mows in one afternoon.

What size garden is this mower suitable for?

Mountfield designed this for lawns up to 150 square metres. With a 30cm cutting width this isn't the fastest mower for larger plots but it handles smaller gardens well.

A few buyers with lawns around 100-110 square metres found it coped fine in a single charge. If your lawn is bigger than 150 square metres you'll likely need to recharge partway through.

How do I adjust the cutting height?

There are 3 height positions ranging from 30mm to 70mm. You adjust this by flipping the mower on its side and fitting the front wheel axle into one of the notches on the housing.

Several reviewers found this fiddly compared to a lever system. One buyer with arthritic hands struggled with the spring mechanism initially, though noted it may loosen with use. Even on the lowest setting the cut isn't razor short, but it leaves a tidy, even finish.

Is the grass collector easy to empty?

Yes. The 30 litre hybrid grass collector is built to be easy to remove and empty. Some buyers mentioned the box can be a little tricky to clip together during initial assembly, needing the clips and slots lined up carefully.

Once assembled though it stays in place well. Most reviewers found this part of the process took less than 5 minutes once they got the hang of it.

How heavy is this mower and can I store it easily?

It weighs just 8.9kg, making it one of the lighter mowers in its class. This matters because a lighter mower is easier to lift over steps, carry to storage or manoeuvre around obstacles like tree trunks and flower beds.

The handlebar folds down too so you can store it in a smaller space such as a shed corner or garage shelf. Dimensions are 118.1cm deep, 40cm wide and 40.5cm high when assembled.

Does it cope with long or wet grass?

This is where opinions differ. Several reviewers noted the motor can stall in long or damp grass and you may need to restart it a few times. One buyer described needing to cut their overgrown lawn in stages, going over it from different angles after letting the grass dry out.

If you keep on top of regular mowing and avoid cutting straight after rain you shouldn't have problems. This is really built as a summer mower for regular upkeep rather than tackling overgrown or wet lawns.

What's included when I buy the battery kit?

The kit comes complete with the Electress 30 Li Kit Cordless Lawnmower, a 30 litre grass bag, the 20V 4Ah battery and a battery charger. Everything you need is in the box so there's no need to buy a battery separately.

Assembly is straightforward too. Most buyers report putting it together in 15 to 20 minutes without needing extra tools beyond what's supplied.

What warranty does this mower come with?

Mountfield backs this with a 5 year manufacturer's warranty, subject to terms and conditions. Spare parts are guaranteed to be available for 5 years within the EU too, which helps if you ever need a replacement wheel or part down the line.

This is a longer warranty period than many cordless mowers in this price bracket offer, giving reasonable peace of mind for a garden tool that sees regular seasonal use.
