The Cobra MX4140VX is a premium cordless rotary lawnmower specifically tailored for the medium-sized British garden. This machine offers the perfect solution for homeowners moving away from maintenance-heavy petrol engines or restrictive electric cables. With a 41cm (16") cutting width, it provides the ideal balance between coverage and agility, navigating intricate garden features and narrow paths with ease.
Built with a high-quality steel deck, the MX4140VX offers a weighted stability that ensures a clean, level cut across the entirety of your lawn, providing a level of durability often missing in plastic alternatives.
At the heart of the MX4140VX is the sophisticated Cobra 40V Lithium-ion system. This model is supplied with two 2.0Ah batteries and a dual-port fast charger as standard, allowing you to charge both units simultaneously.
The brushless motor technology automatically adjusts power delivery based on grass resistance—providing extra torque for thick, overgrown patches and conserving energy on lighter growth. This intelligent management makes it a highly efficient and environmentally friendly alternative to traditional machinery.
Ergonomics are central to the design, ensuring gardening sessions remain fatigue-free.
Vibration Reduction: Soft-grip handlebars significantly reduce the transmission of vibrations to the hands and arms.
Balanced Manoeuvrability: The hand-propelled drive gives the operator total control over the pace, while the balanced weight distribution makes it easy to steer across undulating ground.
Centralised Adjustment: A single-point lever allows you to select from seven different cutting heights (25mm to 75mm) with one simple movement.
This mower offers multiple ways to manage grass clippings depending on your desired finish:
Collection: The 50-litre hybrid grass bag utilises a fabric and plastic design to maximise airflow, ensuring the bag fills to capacity even in damp conditions.
Mulching: An included mulch plug finely shreds clippings and returns them to the lawn surface. These particles act as a natural fertiliser, returning vital nutrients and moisture to the soil.
40V Cordless Technology: High-torque brushless performance with zero emissions.
Dual 2.0Ah Batteries: Supplied with two Samsung Lithium-ion batteries for consistent, fade-free power.
Dual-Port Fast Charger: Conveniently charges both batteries at once to reduce downtime.
41cm Steel Chassis: Robust deck construction for steady tracking and long-term durability.
7-Stage Height Adjustment: Single centralised lever ranging from 25mm to 75mm.
50-Litre Hybrid Bag: Large capacity with a hard top and a "grass-full" indicator.
Quick-Release Folding Handles: Allows for compact storage in sheds or garages.
Safety Key System: Acts as an immobiliser to prevent accidental starts, ideal for family environments.



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.
