Greenworks G40LM41K2X (Green, 41cm Cutting Width)

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

Each 40V 2Ah battery cuts approximately 250m² of grass. With two batteries included, you can cut up to 500m² without recharging. This capacity suits most medium-sized suburban gardens. Battery performance depends on grass thickness, cutting height and terrain conditions. Dense or wet grass may reduce the cutting area slightly.

How does the brushless motor benefit performance compared to standard motors?

Brushless motors eliminate carbon brushes that create friction and wear in traditional motors. This design delivers 30% more power whilst operating significantly quieter. The motor requires no maintenance and lasts considerably longer than brush motors. Heat generation reduces substantially, improving efficiency and extending battery life during operation.

Can I use batteries from other Greenworks 40V tools with this mower?

Yes, all Greenworks 40V batteries are interchangeable across the entire tool range. You can use 2Ah or 4Ah batteries depending on your requirements. The 4Ah batteries provide longer runtime but add extra weight. This compatibility reduces costs if you already own Greenworks tools and eliminates the need for multiple battery types in your garden shed.

What cutting heights are available and how do I adjust them?

Seven cutting positions range from 25mm to 80mm, adjusted via a single lever mechanism. Lower settings create formal lawn finishes whilst higher positions suit longer grass and autumn conditions. The adjustment operates smoothly without tools required. Each position clicks securely into place to prevent accidental height changes during mowing.

How does the mulching function work and what are the benefits?

Mulching mode finely chops grass clippings and redistributes them across the lawn surface. The clippings decompose quickly, returning nitrogen and nutrients to the soil. This natural fertilisation reduces the need for chemical lawn feeds. Mulching also eliminates grass disposal requirements and saves time emptying the collection bag during mowing sessions.

What maintenance does this cordless mower require?

The brushless motor requires no maintenance beyond keeping air vents clear of debris. Clean the cutting deck after each use to prevent grass buildup. Sharpen or replace the blade annually for optimal cutting performance. Battery maintenance involves storing at room temperature and charging every few months if not used regularly. The 50L collection bag should be emptied and cleaned periodically.

How long do the batteries take to charge and what is their lifespan?

The included charger fully charges each 2Ah battery in approximately 120 minutes. Lithium batteries typically provide 300-500 charge cycles before capacity diminishes noticeably. With proper care, batteries should last 3-5 years of regular use. The 2-year battery warranty provides additional peace of mind for early failures or manufacturing defects.

Is the bonus leaf blower powerful enough for autumn leaf clearance?

The GD40BV leaf blower generates 280 km/h air speed with 9.63 m³/min volume capacity, suitable for most garden leaf clearance tasks. Six speed settings allow gentle sweeping around delicate plants or maximum power for stubborn debris. The vacuum function with mulching reduces leaf volume to one-tenth original size, making composting and disposal much more manageable.
