Greenworks 24V Cordless Lawnmower
Designed for smaller lawns up to 140 m², this Greenworks mower mirrors the convenience of petrol power without the noise, fuss, or fumes. It uses a brushless motor for reliability and longer life, paired with a 24V 2Ah battery. The mower supports two power modes with five cutting heights from 25 mm to 70 mm, and offers a 30 L grass bag for simple collection or mulching to return nutrients to the soil. The tool is compatible with other Greenworks 24V products, simplifying storage and upgrades across the system.
Battery and motor reliability are central to performance with minimal maintenance requirements. The 30 L bag capacity reduces frequent emptying, while the mulch mode helps keep lawns healthy. A single lever adjusts cutting height efficiently for changing seasons or grass conditions. This model is an appealing option for those prioritising quiet operation and straightforward maintenance.
Einhell GE-CM 18/33 Li
The Einhell GE-CM 18/33 Li offers cordless freedom for small to medium lawns (up to about 200 m²). It features a brushless motor for longer operating times and reduced wear, with a 33 cm cutting width to balance manoeuvrability and coverage. The Mower kit includes a 4.0 Ah battery and charger, ensuring quick replenishment between sessions. With five cutting heights ranging from 25 to 65 mm, and a 30 L grass box with fill indicator, it delivers reliable mowing while minimizing maintenance challenges.
High-quality plastics and a robust chassis support consistent performance on uneven ground. The edge-edge proximity helps reduce trimming, and the overall design aims to keep noise levels manageable. If you want dependable cordless mowing without frequent battery swaps, this Einhell kit provides solid value.
WORX WG779E.2 40V Cordless Lawn Mower
The Worx WG779E.2 features a dual-battery 40V system (PowerShare) with two 20V batteries included, enabling extended mowing times for larger plots up to around 230 m². Its cut-to-edge design minimizes trimming along borders, while a single-lever height adjustment (with 34 cm cutting width) simplifies season-to-season changes. The twin batteries provide resilience for longer sessions, and the 30 L grass bag keeps clippings under control. It suits gardeners seeking close-to-edge performance plus flexibility to reuse existing WORX batteries.
Greenworks 40V 41 cm Lawn Mower
The Greenworks 40V system powers medium to larger lawns, capable of handling up to 500 m² per battery cycle. It uses two 40V 2Ah batteries so you can alternate between charging and mowing, delivering sustained power for up to 50 cm cutting width with a 41 cm deck. The mower supports both mulch and bagging with a 50 L bag, enabling flexible lawn care. Five cutting heights range from 25 mm to 80 mm, suitable for seasonal shifts and grass density. This is a scalable option for those invested in a 40V Greenworks ecosystem.
LawnMaster MX 24V 34 cm
The LawnMaster MX 24V 34 cm mower is designed for small lawns up to 150 m². It includes two 24V 4.0 Ah batteries and a 1-hour fast charger as part of the MX 24V Shared Battery System, enabling near-continuous run time when used with two batteries. A 6-position cutting height range (20–70 mm) and a rear roller deliver a striped finish, while folding handles aid storage. The kit includes a spare 32 cm blade, supporting maintenance and extended use for tight spaces along borders and edges.
Buying Guide
Battery mower selection hinges on lawn size, battery capacity and interchangeability, plus feature preferences such as mulch capability and edge cutting. Consider the following:
- Lawn size and cutting width: Larger yards benefit from wider decks (about 40–41 cm) and higher power; smaller lawns can maximise compact models (33–34 cm).
- Battery system and exchangeability: Systems with two batteries or PowerShare compatibility reduce downtime. Check if you can reuse existing batteries across tools.
- Cutting height and mulch options: Five to seven height levels (25–80 mm) accommodate seasonal growth and grass conditions. Mulch mode helps return nutrients to the soil.
- Bag capacity and emptying frequency: Larger bags lower the need for frequent emptying, but heavier bags require more lifting. Consider bagless or mulch-only options if preferred.
- Weight, ergonomics and storage: Foldable handles, light weight, and robust wheels improve manoeuvrability on uneven ground and in tight spaces.
- Maintenance and warranty: Brushless motors reduce wear; look for models with good warranties (often around 2–3 years) for peace of mind.
- Noise and emissions: Battery mowers offer quiet operation and zero emissions, beneficial for urban settings and shared spaces.
When choosing, align the features with your garden layout, storage space, and willingness to invest in spare batteries. For households already using a 40V or 24V Greenworks ecosystem, extending to a second tool can maximise value. Consider edge performance, charging times, and whether you prefer bagging or mulching for lawn health and tidy borders.
