16" 40V Max+ Cordless Lawnmower

The Cobra MX51S40VX is a flagship cordless lawnmower that brings professional-grade power and self-propelled convenience to the domestic British garden. Engineered specifically for larger lawns that would traditionally require a petrol engine, this machine offers a massive 51cm (20 inch) cutting width. This wide deck allows the operator to maintain substantial areas of turf with significantly fewer turns and passes, saving time and energy. Built around a durable steel chassis, the MX51S40VX provides the weight and stability required for a perfectly level finish, ensuring that even the most expansive gardens look manicured and healthy throughout the spring and summer seasons.

Powering this heavy-duty machine is the advanced Cobra 40V Lithium-Ion system, utilizing two high-capacity 5.0Ah batteries to provide an exceptional runtime. This dual-battery setup ensures that the brushless motor receives a consistent flow of high-voltage energy, allowing it to maintain blade speed even when encountering thick or slightly damp grass. Included with the mower is a dual-port charger, which ensures both batteries are replenished simultaneously, keeping the machine ready for action. By moving to this cordless platform, homeowners enjoy the high torque and performance of a petrol mower without the associated noise, vibration, or the ongoing requirement to store and mix flammable fuels.

Ergonomics and ease of use are at the forefront of the MX51S40VX design, most notably through its self-propelled drive system. Unlike hand-propelled models, this mower features a powered rear-wheel drive that moves the machine forward at a comfortable walking pace, making it an essential choice for gardens with inclines or for users who prefer a less strenuous mowing experience. The handlebars are equipped with a soft-grip padding and are height-adjustable, ensuring that operators of different statures can maintain a natural, upright posture. The centralised height-of-cut adjustment allows for seven distinct settings, providing the flexibility to leave the grass longer during dry spells or shorter for a formal finish.

The versatility of the MX51S40VX is unmatched, featuring a 3-in-1 cutting system that adapts to every seasonal challenge. For standard lawn maintenance, the 60-litre fabric grass bag provides ample space for clippings, featuring a solid lid that prevents dust and debris from blowing back at the operator. For areas of less formal grass or orchards, the side discharge function can be utilised to quickly eject clippings in neat rows. Finally, the mulch plug can be inserted to recycle the grass; it shreds the clippings into fine particulates that fall back into the lawn, returning vital moisture and nutrients to the soil, which is a highly effective way to maintain lawn health during the peak of the growing season.

Safety, storage, and long-term durability are built into every component of this high-specification mower. The steel deck is treated with a protective coating to resist corrosion, while the front grass comb ensures that blades of grass are upright before they meet the rotary blade for a cleaner, more precise cut. For storage, the handle system features quick-release clamps that allow the entire upper assembly to fold down, significantly reducing the space required in a garage or shed. An integrated safety key system prevents accidental activation, ensuring the mower remains dormant until you are ready to work. This Cobra model is a true petrol-alternative, combining immense power with the refined quietness of modern battery technology.
