Mower Type and Power
Mountedfield Electress 38 Li is a cordless battery lawn mower designed around a 20V system, with a 38cm (15") cutting width aimed at keeping smaller lawns tidy without a power lead. It is a push-style mower powered by the included 20V 4Ah batteries, with a charger provided in the kit. As the power source is battery-based, charging time and battery swapping are required during longer sessions. For compact gardens and quick day-to-day mowing, it is suited to routine use, while very large lawns may require extra batteries.
Cutting Width and Deck
Cutting performance starts with this lawn mower's 38cm (15") cutting width. This deck size influences how much area can be covered in each mowing pass and affects how much overlap may be needed when working around garden edges. The 38cm deck also affects line-keeping during trimming, since cutting close to borders requires careful positioning. The mower suits routine trimming and edging; for longer lawns, slower, tighter passes can make the process feel more time-consuming.
Lawn Size and Collection
For lawn work, the Mountfield's 38 cm cutting width affects how much grass can be covered in each pass, which in turn matters for lawn size. On a small lawn, the 38 cm width can help reduce the number of turns needed to mow the area, and the mowing session can be completed without long breaks. On a medium lawn, more passes are required due to the larger area, and how well the clippings are managed depends on how dense the grass is. On a larger lawn, the single 38 cm cutting width means longer mowing sessions, so the collection area and clippings handling should be planned in advance, with more frequent emptying as the grass area increases.
Ease of Use and Storage
Ease of Use and Storage are shaped by the lawn mower being a cordless, 20V battery lawn mower with a 38 cm cutting width. Handling is usually simpler than with petrol models that require fuel and pull-starting, as there is no engine to manage. After use, the mower can be stored in a shed or garage, since keeping battery tools tidy is typically straightforward. Storage depends on battery care, and the included charger needs to be kept accessible and dry.
Who Is This Lawn Mower For?
This cordless lawn mower is mainly suited to people who want an uncomplicated option for regular grass cutting in smaller to medium gardens. It uses a 20V battery system and has a 38cm (15") cutting width, which suits lawns that do not need frequent heavy-duty passes. It also supports a battery-powered start-up, avoiding fuel handling.
Where to Buy in the UK
Finding the Mountfield kit in the UK is fairly straightforward, as it is sold as a standard cordless lawn mower package. Buyers typically locate it through major garden and home-improvement retailers by searching for the exact kit name, including "38cm" and "20V" details. Some listings describe it as a bundle that includes two 20V (4Ah) batteries and a charger, while other listings may not specify the bundle contents. When comparing results, listings are checked to confirm the cutting width is 38cm and whether two batteries are included.

For keeping a lawn tidy with the least hassle, the Mountfield Electress 38 Li (a cordless mower) does the job with a 38cm cutting width. Whether it suits you comes down to your lawn size, terrain and how much effort you want to put in. Check the current Amazon UK price, as mowers are often discounted in season.
What type of mower is the Mountfield?

Petrol mowers are powerful and cordless for big or rough lawns; cordless battery mowers are quiet and low-maintenance for most gardens; corded electric are light and cheap for small lawns; hover mowers glide for edges and slopes; manual push mowers are eco and silent for tiny lawns. Choose the type for your lawn size and terrain.
What is the cutting width of the Mountfield?
The lawn mower has a 38cm cutting width. A wider deck cuts more grass per pass so you finish faster - better for bigger lawns; a narrower deck is lighter and more manoeuvrable around borders and obstacles. Match the width to your lawn size and how tight the spaces are.
How powerful is this lawn mower?
The Mountfield runs on a 20V battery. Higher battery voltage generally means more cutting power and run time; check the battery is included, as some are sold as bare tools.
Is the Mountfield Electress 38 Li easy to store?
Storage depends on the design - many electric and cordless mowers fold or stand upright to save space, while petrol and ride-on mowers need more room. The lawn mower is a typical example for its type; if space is tight, look for a compact-fold or upright-storage model like Flymo's EasiStore range.
