THE UK'S NO. 1 GARDEN MACHINERY WEBSITE
The Cobra MX3840VX is a sophisticated cordless rotary lawnmower specifically engineered to meet the demands of the modern British garden. Designed for homeowners with small to medium-sized lawns, this machine eliminates the hazards of trailing cables and the maintenance heavy requirements of petrol engines. With a 38cm (15 inch) cutting width, it provides a generous pass that makes quick work of domestic plots while remaining exceptionally manoeuvrable around flower beds, garden furniture, and tight corners. By choosing a cordless system, you are investing in a cleaner, quieter gardening experience that does not sacrifice the robust performance required to maintain a pristine, healthy lawn throughout the growing season.
At the heart of this machine is the advanced Cobra 40V Lithium-Ion battery system, a high-performance power plant that delivers consistent, fade-free energy. The MX3840VX is equipped with 1 x 4Ah battery and a standard charger, ensuring you have the capacity to finish the job without interruption. Unlike older battery technologies, these Samsung-powered cells are designed for longevity and rapid charging, providing the brushless motor with the high torque needed to tackle thicker grass or damp conditions. The integration of a battery power indicator allows the operator to monitor energy levels at a glance, ensuring you are never caught off guard mid-mow, making it a reliable alternative to traditional fossil-fuel machinery.
User comfort is a primary focus of the Cobra design philosophy, and the MX3840VX excels in its ergonomic execution. The mower features a lightweight polymer deck that is both durable and easy to push, significantly reducing the physical strain on the operator compared to heavy steel-decked alternatives. The soft-grip handles are designed to dampen vibrations, allowing for longer working periods without discomfort or fatigue. Furthermore, the inclusion of a central height-of-cut adjustment lever means you can transform the look of your lawn with a single, effortless movement, shifting through five stages to suit the seasonal requirements of your turf without having to adjust each wheel individually.
This mower offers remarkable versatility through its 2-in-1 cutting system, providing professional-grade results regardless of your preferred lawn care method. For those who desire a tidy, debris-free finish, the 40-litre grass collector uses a premium fabric and hard-top hybrid design to optimise airflow and maximise collection efficiency. Alternatively, for gardeners looking to improve the biological health of their soil, the included mulch plug can be inserted. This function finely shreds the grass clippings and recirculates them into the lawn base, where they decompose rapidly and act as a natural, nitrogen-rich fertiliser, reducing the need for chemical treatments and keeping your garden lush and green.
Storage and safety have been integrated seamlessly into the MX3840VX’s build. Once the gardening task is complete, the quick-release folding handles allow the mower to be collapsed into a compact footprint, making it ideal for those with limited space in their garden buildings. Safety is paramount; the machine requires a safety key to operate, preventing accidental startups by children or unauthorised users. The robust front comb helps to guide the grass into the blades for a cleaner cut, while the integrated carry handle makes transporting the unit over steps or into a vehicle simple and secure. Every aspect of this Cobra mower is built to provide a premium, hassle-free experience for the discerning UK gardener.
The COBRA 40V MAX PLUS batteries are a step ahead of the competition in terms of technology and innovation. Our intelligent technology is carefully embedded into the battery pack design, resulting in a longer lasting and more efficient battery. The 40V Max+ batteries offer several advantages: one battery fits all 40V Max+ tools, they deliver high-performance power, run longer, and recharge faster. run longer, and recharge faster.
The Cobra M3840VX lawnmower features a robust 15" cutting deck, making it an excellent choice for small to medium-sized lawns. This cutting deck size allows for efficient and precise mowing, ensuring a clean, even cut with each pass. The 15" width strikes a perfect balance between manoeuvrability and coverage.
The Cobra MX3840VX lawnmower is built with a lightweight yet durable polymer deck, weighing just 12.7kg (without battery). This clever construction significantly reduces the overall weight of the mower, making it easier to handle and manoeuvre around the garden. In addition to its lightweight benefits, the tough polymer material offers excellent durability and resistance to corrosion, ensuring the mower stands up well to regular use.
The ergonomic operator controls on the Cobra MX3840VX are thoughtfully designed with both user comfort and safety in mind. Positioned intuitively for ease of use, these controls offer precise handling and complete control while mowing. Whether you're working around flower beds, tight spaces, or tackling uneven ground, the well-balanced layout helps minimise fatigue and ensures a comfortable, secure grip from start to finish. re-cutting the clippings.
