Why Choose This Lawnmower.

The Cobra MX3840VX is a lightweight, hand-propelled cordless lawnmower powered by the advanced 40V MAX+ Li-ion battery system. With a 38cm cutting width and 5 adjustable heights from 25mm to 75mm, it’s perfect for small to medium-sized lawns. Weighing only 12.7kg, it’s easy to handle and features a tough polymer deck for durability. Front & Side combs help deliver a cleaner cut, while the included mulch plug offers an eco-friendly way to feed your lawn. A 40ltr grass bag means fewer stops to empty clippings. (Not compatible with standard Cobra 40v batteries). 

DESIGNED WITH YOUR GARDEN IN MIND

LIGHTWEIGHT DESIGN
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.
ERGONOMIC CONTROLS
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. 
25-75mm CUT HEIGHTS
5 cutting heights, ranging from 25mm to 75mm — perfect for achieving everything from a clean, close cut to managing thicker, overgrown grass. Height adjustment is quick and effortless thanks to the centrally positioned single height-of-cut lever, allowing you to switch between settings with ease and precision.
