The Cobra MX4140VX is a premium cordless rotary lawnmower that represents the pinnacle of modern gardening technology, specifically tailored for the medium-sized British garden. This machine offers the perfect solution for homeowners who want to move away from the maintenance-heavy world of petrol engines or the restrictive nature of electric cables. With a 41cm (16 inch) cutting width, it provides the ideal balance between coverage and agility, allowing you to cover larger areas of turf quickly while still maintaining the ability to navigate around intricate garden features, narrow paths, and flower borders with ease. The steel deck construction provides a weighted stability that ensures a clean, level cut across the entirety of your lawn.
At the heart of the MX4140VX is the sophisticated Cobra 40V Lithium-Ion battery system, which delivers consistent, fade-free power throughout the entire mowing cycle. This model is supplied with two 2.0Ah batteries and a dual-port charger as standard, meaning you can charge both power units simultaneously to reduce downtime. The brushless motor technology is engineered to optimise battery life by automatically adjusting the power delivery based on the resistance of the grass, providing extra torque when you encounter thick, overgrown patches and conserving energy on shorter, lighter growth. This intelligent energy management makes it a highly efficient and environmentally friendly alternative to traditional fossil-fuelled machinery.
Ergonomics and operator comfort are central to the design of this mower, ensuring that even extended gardening sessions remain pleasurable and fatigue-free. The MX4140VX features an ergonomically designed handlebar system with a soft-grip finish that significantly reduces the transmission of vibrations to the hands and arms. The controls are intuitively placed for easy access, and the overall weight distribution of the machine is balanced to allow for effortless manoeuvring across undulating ground. Furthermore, the inclusion of a single-point, centralised height adjustment lever eliminates the need to adjust each wheel individually, allowing you to select from seven different cutting heights with one simple movement to suit the seasonal condition of your grass.
This mower is remarkably versatile, offering the user multiple ways to manage their grass clippings depending on the desired finish and the health of the soil. For a pristine, formal look, the high-performance 50-litre grass collector utilizes a hybrid design of fabric and plastic to maximise airflow, ensuring the bag is filled to capacity even in damp conditions. If you prefer a more ecological approach, the included mulch plug can be utilised to finely shred clippings and return them to the lawn surface. These tiny particles decompose rapidly, acting as a natural fertiliser that returns vital nutrients and moisture to the soil, promoting a lush, vibrant green lawn without the need for additional chemical treatments.
When the job is done, the Cobra MX4140VX continues to impress with its practical storage and safety features designed for the modern household. The handle system features quick-release levers that allow the bars to fold completely over the body of the mower, making it easy to store in a compact space within your shed or garage. For safety, the machine is equipped with a safety key that must be inserted before the motor can start, providing peace of mind for families with children. The durable steel deck is easy to clean, and the integrated front carry handle makes it simple to lift the machine over steps or into a vehicle. This mower is a comprehensive tool built to provide professional results with the convenience of cordless freedom.



Built directly into the battery pack, this smart system allows the battery to recognize the specific Cobra tool it’s being used with, automatically optimizing output for peak efficiency. The 40V Max+ batteries offer several advantages: one battery fits all 40V Max+ tools, they deliver high-performance power, run longer, and recharge faster.


The Cobra MX4140VX lawnmower features a sturdy 41cm (16") cutting deck, making it an ideal choice for maintaining small to medium-sized lawns with ease. Its compact deck strikes the perfect balance between manoeuvrability and coverage, allowing you to navigate around garden features and tight spaces effortlessly. The 16-inch width delivers a clean, precise cut with every pass, helping you achieve a neat, well-kept lawn with minimal effort.


The new Cobra MX4140VX is equipped with innovative grass combs at the front, designed to lift and guide the grass into the cutting blades for a cleaner, more efficient cut, helping you achieve a beautifully even and well-groomed lawn with ease.


The Cobra MX4140VX features ergonomically designed operator controls that prioritise comfort and ease of use. Thoughtfully positioned for intuitive operation, these controls offer precise handling and full control of the mower, even in tricky areas such as narrow spaces, around garden borders, or across uneven ground. Its well-balanced design helps minimise fatigue and provides a secure, comfortable grip throughout your mowing.


The MX4140VX cordless lawnmower from Cobra comes equipped with a mulch plug to enable you to mulch your grass clippings back into the lawn. Mulching lawnmowers recycle the grass by finely cutting and re-cutting the clippings.


For those seeking precision and flexibility in lawn care, the Cobra MX4140VX is an excellent choice. It features a fully adjustable cutting system with multiple height settings, allowing you to easily tailor the cut to suit your lawn’s needs — from a close trim at 25mm to handling longer grass up to 75mm. Adjusting between these settings is quick and effortless, thanks to the mower’s convenient single height-of-cut lever.
