About the COBRA MX51S40VX Petrol Lawnmower
Powerful Cordless Lawn Care
The Cobra MX51S40VX 20″ Lithium-ion 40V MAX PLUS Cordless Lawnmower combines strength, convenience, and cutting-edge technology. This self-propelled mower is powered by two 40V MAX+ Li-ion batteries, delivering reliable cordless performance without fumes or noise. The brushless motor ensures consistent output, longer run times, and reduced maintenance, making it a smart choice for modern lawn care.
Efficient Cutting and Versatile Operation
With a 51cm (20″) cutting width, this mower is ideal for medium and large lawns. The size balances efficiency and manoeuvrability, letting you cover wide areas while easily steering around garden obstacles. The mower features a 7-stage height adjustment system ranging from 25mm to 75mm, controlled by a single lever. This design allows you to choose between a neat low cut or tackling longer grass with ease.
Comfortable Self-Propelled Design
The self-propelled drive system reduces physical effort, letting the mower handle inclines and large areas with minimal strain. This feature is especially useful for users with uneven lawns or those who want easier mowing sessions. With this support, maintaining your lawn becomes a comfortable task, not a chore.
Three-in-One Grass Management
The Cobra MX51S40VX offers outstanding versatility with its 3-in-1 collection system. You can collect clippings in the large 60L grass bag, use the mulch plug to return nutrients to the lawn, or switch to side discharge for tackling thick or tall growth. This flexibility ensures you always have the right option for your lawn’s condition.
Innovative Grass Combs for Cleaner Results
Designed for precision, the mower includes front-mounted grass combs that lift blades upright before cutting. This innovative feature aligns grass perfectly for trimming, producing an even and professional-looking finish. The combs improve efficiency by guiding grass directly into the cutting path for consistently tidy results.
Comfort and Ergonomic Features
The MX51S40VX is built with user comfort in mind. Its adjustable handles offer three angle positions, ensuring a comfortable posture for users of different heights. The soft-grip handles reduce vibration and hand fatigue, making extended mowing more enjoyable and controlled. For added convenience, the folding handle system allows for easy storage and transport.
Strong Build and Reliable Power
This mower is built with a durable steel deck, ensuring strength and longevity for years of use. Weighing 30.4kg without the battery, it strikes the right balance between stability and manoeuvrability. The intelligent battery system recognises the tool in use and optimises performance for maximum efficiency. With fast charging times and long run times, the 40V MAX+ batteries deliver dependable power across all compatible tools in the range.
