The Greenworks GD24X2LM46SPK4X is a high-performance cordless lawn mower built for homeowners who need strong cutting power without the noise and maintenance of petrol machines. Powered by Greenworks’ innovative dual 24V battery system (48V combined), this mower delivers excellent runtime and performance while remaining quiet and emission-free.
Designed for medium to large lawns, it features a 46 cm cutting width and self-propelled drive, making it easier to cover larger areas with less effort. The mower also includes 7 adjustable cutting heights from 25–80 mm, allowing you to tailor the finish to your lawn’s condition.
Its 55-litre grass collection bag reduces emptying stops, while the 3-in-1 cutting system lets you choose between collection, mulching, or side discharge for added versatility. Overall, the GD24X2LM46SPK4X is a premium cordless mower ideal for users wanting petrol-like performance with battery-powered convenience.
Greenworks 48V Self-Propelled 46cm Mower
You get close to petrol performance without the noise, fumes, or frequent servicing — ideal if you value power and convenience. For lawns up to about 480 m² it balances cut width, collection capacity and handling; for much larger sites plan on an extra battery pack.
Overview
You’re looking at a cordless lawn mower that aims to replace petrol models for many homeowners. The Greenworks 48V (2x24V) self‑propelled mower combines a brushless motor, a 46 cm steel deck and a dual‑battery system to deliver high cutting performance with the convenience of battery operation. The machine’s design prioritises cutting power, variable height control and operator comfort, while keeping day‑to‑day maintenance far simpler than combustion alternatives.
Powertrain and batteries how the 48V system works for you
The mower uses two 24V batteries working together to provide the equivalent of a 48V system. This configuration allows high torque for the blade and the self‑propel gearbox while keeping battery packs compatible with Greenworks’ 24V ecosystem. The inclusion of two 4Ah batteries and a twin charger gives you a practical starting runtime and reduces downtime compared with single‑battery kits.
Expectations and practical runtime: typical users report between 30–90 minutes per full charge depending on grass height, ground slope and drive assistance usage. If you have a single contiguous lawn at the upper end of the 480 m² claim, plan on either staggered mowing or an extra battery set to avoid interruptions.
Cutting system and deck what the 46 cm width delivers
The 46 cm cutting width sits in the sweet spot for homeowners with medium‑to‑large lawns: wider than compact battery mowers, but still narrow enough to navigate tighter garden features. The steel deck offers ballast and solidity, which supports a clean, even cut especially when you use the mulching or collection modes.
Key cutting attributes:
Quick reference: recommended cutting heights
| Situation | Recommended height (mm) |
|---|---|
| First cut of the season / tall grass | 60–80 |
| Regular maintenance in growing season | 30–50 |
| Short, tidy finish | 25–35 |
The cutting deck’s three modes give you flexibility: collect the clippings to keep a tidy lawn, mulch to return nutrients to the soil, or side discharge for heavy growth or wet grass where clipping ejection prevents clogging.
Ergonomics, handling and storage practical day to day use
The mower is self‑propelled, which reduces the physical effort required when mowing undulating ground or longer sessions. Rear wheels of about 25 cm help with traction and maneuverability. The handlebar features straightforward controls for blade engagement and propulsion; however, users should expect a learning curve to operate the start sequence safely and consistently.
You will notice the unit’s weight when lifting it out of packaging or into storage: the steel deck contributes to sturdiness but increases mass. The handle folds down to save space and the batteries are removable for charging or storage.
Maintenance, durability and warranty
Compared with petrol machines, maintenance is simpler: there’s no fuel, oil changes, carburettors or spark plugs. The brushless motor reduces wear compared with brushed alternatives and the steel deck resists flexing under load. Regular maintenance tasks you will perform include blade sharpening/replacement, emptying and cleaning the collection bag, and keeping the deck underside free from debris.
Who this mower fits and who should consider alternatives
If your lawn is up to roughly 480 m², you’ll likely find this mower a good match. It’s particularly attractive if you want near‑petrol cutting performance without smoke, frequent servicing or the noise of an internal combustion engine. The included batteries and twin charger mean you’re ready to mow out of the box.
If you have much larger lawns (e.g., >500–600 m² continuous area), steep inclines, or you need stripe‑perfect finish for show lawns, consider a higher‑capacity battery solution, a ride‑on, or a petrol mower with a larger engine. Similarly, if frequent lifting or transport is required, the weight may be a limiting factor for some users.
Practical tips before you buy
Summary
The Greenworks 48V self‑propelled mower is a solid, well‑rounded cordless option that brings high cutting power, flexible deck options and a convenient twin‑battery kit. It replaces many petrol tasks quietly and with less day‑to‑day fuss. You trade some portability (weight) and absolute runtime (unless you add batteries) for cleaner operation and lower maintenance demands, which is a worthwhile exchange for many homeowners.
FAQs
Runtime varies with grass height, slope and whether you use self‑propel. In practical use expect approximately 30–60 minutes per full charge. Lighter trimming sessions on short grass will be at the higher end; heavy first‑of‑season cuts will shorten run time. If you need continuous long sessions, plan a second battery set.
Yes — the twin charger supplied is designed to charge the two 24V 4Ah batteries simultaneously or sequentially. Charging both before mowing reduces downtime and lets you swap batteries mid‑job if required.
Yes. Brushless motors run more efficiently, produce less heat, and need less maintenance than brushed motors. That translates into longer motor life and better power delivery under load — important when tackling thicker or damp grass.
It will handle gentle to moderate slopes well thanks to the self‑propel system and large rear wheels. For steep or very uneven terrain, you should exercise caution — battery mowers can lose traction and are heavier to manoeuvre when lifted.
Yes — sharpen the blade at least once per season for typical domestic use, and more often if you frequently cut long or abrasive grass. A well‑sharpened blade gives cleaner cuts, reduces plant stress and improves battery efficiency.
Battery mowers are significantly quieter than petrol machines. You’ll still hear the blade and motor, especially under load, but noise levels are lower and less intrusive — useful for residential areas with noise restrictions.
Check the collection bag for tears, inspect the deck underside for wrapped debris, confirm battery charge and condition, and wipe down controls. Periodic checks of wheel bearings and the blade mounting are sensible preventive steps.
