Cobra MX460S40VX 18" Self-Propelled Cordless Lawnmower (46cm, Red and Silver)

How long does the 40V 4Ah battery last during mowing?

The 4Ah battery typically provides 45-60 minutes of continuous mowing time depending on grass conditions and terrain. Dense or wet grass reduces runtime whilst lighter conditions extend it. The self-propelled feature uses additional power but the 40V system maintains consistent performance throughout the charge cycle. Battery life improves after several charge cycles as the cells condition.

Can this mower handle slopes and uneven terrain effectively?

Yes, the self-propelled drive system provides excellent traction on slopes up to 15 degrees. The 24kg weight provides stability whilst the drive wheels maintain grip on uneven surfaces. The steel deck construction prevents damage from ground contact on bumpy terrain. However, extremely steep slopes may require manual pushing for safety reasons.

What maintenance does this cordless mower require?

Maintenance involves cleaning the deck after use, checking blade sharpness annually and storing the battery at 50% charge during winter. No oil changes, spark plug replacements, or air filter cleaning required like petrol models. The steel deck benefits from occasional rust prevention treatment. Blade replacement every 2-3 years maintains optimal cutting performance.

How does the mulching function work and when should I use it?

The included mulching plug blocks the rear discharge and recirculates clippings under the deck for finer chopping. This returns nutrients to the soil naturally whilst eliminating grass disposal. Use mulching mode when grass is dry and not overly long. Remove the grass bag and install the plug for mulching operation. This works best with regular weekly mowing schedules.

Is the 46cm cutting width suitable for my garden size?

The 46cm width suits gardens from 200-800 square metres effectively. Smaller gardens may find it too wide for tight spaces whilst larger areas might require multiple battery charges. The cutting width balances efficiency with manoeuvrability around flower beds and garden features. Consider your garden's layout and obstacle density when determining suitability.

How long does the battery take to charge fully?

The standard charger requires approximately 90-120 minutes for a complete charge from empty. Charging time varies slightly based on ambient temperature and battery age. The charger includes LED indicators showing charge progress. Partial charges work effectively if you need to resume mowing before full charge completion. Store the charger in dry conditions for longevity.

Can I purchase additional batteries for extended mowing time?

Yes, Cobra 40V 4Ah batteries are available separately and interchange between compatible Cobra tools. Additional batteries allow continuous mowing of larger areas by swapping when one depletes. The battery system works across Cobra's 40V range including strimmers and hedge cutters. Consider a second battery if your garden exceeds 600 square metres.

What happens if the mower encounters thick or wet grass?

The 40V motor maintains torque in challenging conditions but may slow cutting speed through thick growth. Wet grass can clog the discharge chute and reduce collection efficiency. Raise the cutting height and reduce forward speed in difficult conditions. The motor protection system prevents damage by reducing power if overloaded. Clean the deck promptly after cutting wet grass to prevent corrosion.
