Greenworks 2504707UC 40V Cordless Lawnmower (Green/Black/Grey, 41cm)

How long do the batteries last and how long to charge?

Each 2Ah battery cuts approximately 250m² of grass on a single charge, giving you 500m² total coverage with both batteries. Actual runtime depends on grass thickness, height setting and terrain. From completely flat, each battery takes around 40 minutes to fully charge. The charger won't start charging hot batteries - allow 20-30 minutes cooling time after heavy use before charging begins.

Can I use this mower on slopes and uneven ground?

Yes, the large 18cm rear wheels and lightweight design make this mower excellent for slopes and bumpy terrain. The wheel size helps it roll over divots, mole hills and uneven surfaces that smaller wheels struggle with. However, very steep slopes may require extra care due to the mower's light weight. The battery system provides consistent power regardless of angle, unlike petrol mowers that can struggle on inclines.

What's the difference between mulching and collection modes?

Collection mode uses the 50L grass bag to gather clippings for disposal or composting. This works best for longer grass or when you want a completely clean finish. Mulching mode chops grass into tiny pieces that fall back onto the lawn, decomposing quickly to feed the soil. Mulching works best with regular cutting and shorter grass lengths. You can switch between modes without tools.

Is this suitable for thick, fertilised grass?

The mower handles average grass well but can struggle with very thick, lush grass that's been heavily fertilised. The motor relies on high RPM rather than high torque, so dense grass can cause the blade to bog down or stall. For best results with thick grass, use a higher cutting height setting and ensure the blade stays sharp. Some users report better performance by cutting more frequently to prevent grass becoming too thick.

How does the cutting height adjustment work?

A single lever simultaneously raises or lowers all four wheels, adjusting cutting height from 25mm to 80mm across five positions. This is much easier than mowers requiring individual wheel adjustment. The system includes a plastic indicator (though this can break) to show current height setting. All wheels maintain the same height automatically, ensuring even cutting across uneven terrain.

Are the batteries compatible with other tools?

Yes, both batteries work with the entire Greenworks 40V tool range including hedge trimmers, chainsaws, strimmers and leaf blowers. This compatibility saves money and storage space compared to buying separate battery systems for each tool. The batteries feature the same slide-on attachment system across all tools. You can build a complete cordless garden tool collection using the same battery platform.

How easy is it to empty the grass bag?

The 50L grass bag attaches and detaches easily using a simple clip system. When full, lift the bag off and empty it into your compost bin or garden waste. The bag's fabric construction allows airflow for better grass collection and the collapsible design means it folds flat for storage. The large capacity means fewer emptying trips compared to smaller bags on compact mowers.

What maintenance does this mower require?

Maintenance is minimal compared to petrol mowers - no oil changes, spark plugs or air filter cleaning required. Keep the blade sharp for best cutting performance and clean grass buildup from the deck after use. Check the grass bag for tears and ensure battery contacts stay clean. Store batteries in a cool, dry place and charge them every few months if not used regularly. The steel blade may need sharpening or replacement after extended use.
