The LawnMaster MX 24V 34cm Cordless Lawnmower is a compact and efficient battery powered mower designed for homeowners who want easy, cable free lawn care. Built for small to medium sized gardens, it offers a great balance of performance, portability, and convenience without the noise or maintenance of petrol machines.
Powered by a 24V lithium-ion battery system, many versions include dual batteries, allowing longer runtime and continuous mowing by swapping or charging one while the other is in use. The mower features a 34 cm cutting width and six adjustable cutting heights (20–70 mm), making it suitable for regular lawn maintenance and different grass conditions.
It also includes useful features like a brushless motor with intelligent power control, which adjusts performance based on grass thickness, and a 32-litre grass collector or mulching option for flexible use.
Overall, the LawnMaster MX 24V 34cm is a lightweight, user-friendly, and versatile cordless mower, ideal for keeping smaller lawns neat with minimal effort.
LawnMaster MX 24V 34cm Mower with 2 Batteries
You get reliable cordless runtime from the twin batteries and a fast charger, combined with a neat striped finish from the rear roller. It’s lightweight and easy to store, but it’s not built to replace a petrol mower for heavy first cuts or very long grass.
Overview
You’re looking at a compact cordless solution designed for small to medium lawns where convenience and low maintenance matter more than brute power. The mower is supplied with two 24V 4.0Ah lithium-ion batteries and a fast charger so you can swap batteries and keep working without long downtime. The design prioritises ease of use, a neat finish and compact storage rather than handling large, overgrown turf.
What’s included in the box
Key features explained
The package is built around a shared MX 24V battery system philosophy. That means the batteries are intended to be used across compatible tools, extending the flexibility of your investment. The mower manages its own power output: when it detects lighter grass it conserves energy, and when heavier loads are encountered it temporarily increases output to maintain cut quality. You’ll see the practical value of that behaviour on mixed lawns where conditions vary across the garden.
Cutting system and finish
The blade and height range give you control over finish and frequency of mowing. On regularly maintained lawns you’ll achieve a clean, striped appearance at the lower heights; on the other hand, if you leave the grass long you’ll find the mower slower and more taxing on the batteries. The manufacturer’s warning that it’s not designed for sustained heavy-duty first cuts is worth heeding.
Battery system, runtime and charging
In practice you can expect to complete typical small/medium gardens using both batteries in sequence. Single-battery jobs are possible for shorter lawns. Note that batteries should be allowed to cool before recharging for optimal charger performance — if you finish a long session, expect a short cool-down window before the fast charge can begin.
Handling, weight and storage
The lightweight build makes manoeuvring around beds and over steps simple. The trade-off is predominantly in the construction materials — it’s engineered for portability more than heavy-duty robustness. Folding requires loosening wingnuts rather than a quick-release latch, which is safe but slower if you fold/unfold very frequently.
Mulching vs collection
You can choose to collect clippings in the supplied 32L Redi-bag or use the mulch plug to finely chop clippings and return nutrients to the lawn. Mulching will reduce the waste you need to remove and is effective on regular, short-mown lawns. Collection is preferable when you want a tidy finish or when the grass is damp or abundant.

Pros and limitations in practice
Final practical tips
By balancing convenience, compact storage and included battery capacity, this model is a strong candidate when you prioritise ease of use and value over heavy-duty cutting performance. If you match the tool to regular maintenance cycles and the scale of your garden, it delivers predictable, tidy results with low fuss.
FAQ
Expect each 24V 4.0Ah battery to cover a modest-sized lawn on its own; for larger small/medium lawns you’ll typically use both in sequence. Real-world runtime varies with grass length, motor load and cutting height — regular short cuts use less power than first-of-season long grass.
Yes — the mower is supplied with two batteries and a fast charger so you can run on one battery and recharge the other, which gives near-continuous operation for multiple lawns, provided you allow batteries to cool before charging.
You can use it on mildly uneven or sloped lawns; the lightweight design helps with manoeuvrability. Steeper slopes or very rough terrain will reduce traction and cutting consistency, and may increase battery drain, so assess conditions before use.
Mulching returns finely chopped clippings to the turf and reduces green waste; it’s best on short, dry grass. Collection gives a tidier surface and is preferable when the grass is wet, plentiful or when you prefer immediate removal.
Routine tasks include cleaning the underside of the deck, checking and sharpening or replacing the blade as needed, and storing batteries in a cool dry place. Regular checks of fasteners and visual inspection of plastic parts will extend life.
Yes — the batteries are part of the MX 24V shared system, which means they can typically be used in other compatible MX 24V garden tools, expanding flexibility and value across the tool range.
