Greenworks GD40LM46SP Self Propelled Cordless Lawnmower (46cm, With 4Ah Battery)

What size lawn can this mower handle on a single charge?

The lawn coverage depends on the battery capacity used. With a 2Ah battery, you can mow lawns up to 300m², whilst a 4Ah battery extends this to 600m². The optional 6Ah battery can handle up to 750m². Runtime also varies based on grass conditions, cutting height and terrain. Thicker grass and lower cutting heights will reduce the coverage area per charge.

How does the self-propelled system work?

The self-propelled system uses the motor to drive the large 25cm rear wheels automatically. You simply guide the mower's direction whilst the wheels provide forward motion, eliminating the need to push. The system maintains consistent speed across different terrain types, making it particularly useful on slopes or uneven ground where pushing would be more difficult.

Can I use batteries from other Greenworks tools?

Yes, this mower is compatible with all Greenworks 40V batteries including 2Ah, 2.5Ah, 4Ah and 6Ah variants. If you already own other Greenworks 40V tools, you can share batteries between them, reducing costs and storage requirements. The battery features an LED display showing charge status and can be charged at any level without memory effect.

What's the difference between mulching and collection modes?

Mulching mode cuts grass clippings into fine pieces that decompose quickly, returning nutrients to the soil and reducing the need for fertiliser. Collection mode gathers clippings in the 55L bag for a tidy finish, ideal for formal lawns or when grass is particularly long. Side discharge ejects clippings to the side, useful for very long grass or when the bag is full.

How much does the mower weigh and is it easy to store?

The mower weighs 29kg including the battery, making it manageable for most users whilst providing stability during operation. The handlebar folds down for compact storage, reducing the storage footprint significantly. The metal construction ensures durability whilst the weight distribution helps maintain traction on slopes and uneven terrain.

What maintenance does this cordless mower require?

Maintenance is minimal compared to petrol mowers. Regular tasks include cleaning the deck after use, checking blade sharpness annually and ensuring battery contacts remain clean. There's no oil changes, spark plug replacements, or fuel system maintenance required. The brushless motor eliminates the need to replace carbon brushes, further reducing maintenance requirements and costs.

How long does the battery take to charge?

Charging times vary by battery capacity and charger type. A 4Ah battery typically takes 2-4 hours to fully charge with a standard charger, whilst fast chargers can reduce this time significantly. The battery can be charged at any level without memory effect, so you don't need to fully discharge before recharging. The LED display shows charging progress and remaining capacity.

Is this mower suitable for slopes and uneven terrain?

Yes, the self-propelled system and large rear wheels make it well-suited for slopes and uneven terrain. The 25cm rear wheels provide good traction and stability, whilst the self-propelled drive maintains consistent forward motion on inclines. However, always exercise caution on steep slopes and follow the manufacturer's safety guidelines for maximum gradient recommendations.
