Product Features

Dual 20V Battery System - Two 4Ah lithium-ion batteries provide up to 50 minutes of runtime, enough for lawns up to 640 square metres. The quick-exchange system allows instant battery swapping, whilst each battery doubles as a USB-C power bank for charging devices during garden work. Brushless Induction Motor - The high-efficiency motor delivers 2900 rpm with reduced maintenance requirements and quieter operation compared to petrol alternatives. The brushless design eliminates friction wear points, extending motor life whilst providing consistent cutting power even in thick grass conditions. 3-in-1 Cutting Versatility - Switch between rear discharge for open areas, mulching to return nutrients to soil, or collection mode using the 50-litre hard-top collector. The viewing window lets you monitor fill levels, whilst ventilation slots maintain optimal airflow for efficient grass collection.
Central Height Adjustment - Six cutting positions from 25mm to 75mm accommodate different grass types and seasonal requirements. The single-lever system adjusts all four wheels simultaneously, ensuring level cuts across uneven terrain whilst maintaining consistent grass height throughout your lawn. Lightweight Ergonomic Design - At 19kg, the mower reduces physical strain during extended use. The three-position adjustable handle with soft grip minimises vibration transfer, whilst the folding mechanism enables compact storage in sheds or garages with limited space. Weather-Resistant Construction - Impact-resistant plastic housing withstands outdoor storage and accidental impacts. The weatherproof design protects internal components from moisture, whilst the balanced weight distribution ensures stable operation on slopes up to 15 degrees without compromising cut quality.

FAQs

How long do the batteries last and what area can I cut?

The dual 4Ah batteries provide up to 50 minutes of continuous runtime, sufficient for lawns up to 640 square metres according to manufacturer specifications. Real-world testing shows approximately 60 square metres can be cut in under 8 minutes with 95% battery remaining. Battery life depends on grass thickness, cutting height and terrain conditions.

Can I use these batteries with other Murray tools?

Yes, the 20V batteries are compatible with the entire Murray cordless tool range. Each battery also features a USB-C port that functions as a power bank for charging mobile devices, tablets, or other USB-powered equipment during garden work.

What's the difference between the three cutting modes?

Rear discharge mode expels clippings behind the mower for quick cutting of longer grass. Collection mode fills the 50-litre collector for tidy lawns and easy disposal. Mulching mode finely chops clippings and returns them to the soil as natural fertiliser, eliminating the need for emptying whilst nourishing your lawn.

How do I adjust the cutting height and what heights are available?

The central lever system adjusts all four wheels simultaneously across six positions from 25mm to 75mm. This range covers everything from fine ornamental lawns (25-35mm) to longer utility grass (65-75mm). The single-lever design ensures all wheels remain level for consistent cutting results.

Is the grass collector easy to remove and empty?

The 50-litre hard-top collector features integrated handles for easy lifting and a viewing window to monitor fill levels. However, some users report the attachment clips can be fiddly and may occasionally detach on uneven ground. The collector empties easily but requires proper alignment when reattaching to the mower deck.

How long does it take to charge the batteries?

The included dual charger can recharge both 4Ah batteries simultaneously. Charging time varies based on depletion level, but typically takes 2-3 hours for completely flat batteries. The charger features LED indicators showing charging progress - flashing green during charging and solid green when complete.

What maintenance does this mower require?

The brushless motor requires minimal maintenance compared to petrol alternatives. Regular tasks include cleaning grass buildup from the deck, checking blade sharpness annually and storing batteries at room temperature during winter. The impact-resistant housing can be cleaned with water, but avoid pressure washing the motor housing.

Can this mower handle thick or wet grass?

The 2900 rpm brushless motor provides sufficient power for most grass conditions, including moderately thick growth. However, very wet grass may cause clogging in collection mode and extremely thick grass may reduce battery runtime. For best results, cut when grass is dry and avoid letting growth exceed 6 inches between cuts.
