Hand propelled, 40v 4.0Ah Li-ion MAX+ battery, 38cm polymer deck, 5 height options, 40L bag

Every Cobra lawnmower has been expertly designed in the U.K to cater specifically for the changing conditions of the British lawn.

The Cobra MX3840VX cordless Lithium-ion lawn mower allows you to get more done without the need for petrol or electrical cables. The MX3840VX is hand propelled, has a quality plastic deck and 5 cutting heights, in addtion to the Vortex airflow collection system & 40L collection bag.

The Cobra MX3840VX is powered by a Cobra 40V MAX+ Lithium-ion battery offering a quiet, yet powerful and lightweight combination. The Cobra 40V MAX+ batteries are a step ahead of the competition in terms of technology & innovation. Intelligent technology is carefully embedded into the battery pack design, resulting in a longer lasting & more efficient battery. The 40V MAX+ batteries offer several advantages: one battery fits all 40V MAX+ tools, they deliver high-performance power, run longer, & recharge faster.

With a cutting width of 38cm / 15", the Cobra MX3840VX lawn mower also has 5 adjustable cutting heights ranging from 25mm for a superb low finish, up to 75mm for tackling longer grass. All this is achieved by simply using the single height of cut adjustment lever. Depending on the height of your grass, you can easily and efficiently adjust the cutting height to suit.

The ergonomic operator controls on the Cobra MX3840VX are designed with user comfort and safety as a priority. Intuitively positioned and easy to operate, these controls provide precise handling and full command while mowing. Whether you're navigating tight corners or managing uneven terrain, the thoughtfully balanced layout helps reduce fatigue and ensures a firm, secure grip throughout the job.

In addition to its lightweight, yet durable polymer deck & rotary cutting blade, a standout feature of the Cobra MX3840VX mower is its new deck design with a volute-shaped VorteX airflow system. This boosts grass collection by powerfully lifting & packing clippings into the bag, even in damp or dense conditions, while preventing clogging and ensuring a clean, even cut. Edge & front grass combs ensure a neat finish, while the included mulch plug offers eco-friendly cutting options. Mulching lawnmowers recycle the grass by finely cutting and re-cutting the clippings. As the clippings decompose, nutrients and fertilisers are returned to the soil meaning you can cut the grass and fertilise at the same time.

The Cobra MX3840VX features infinate handle angle adjustments, allowing for personalised comfort for operators of all heights. It also has has the added benefit of folding handles making storage in your garage or shed even easier. Folding handles produce a much smaller footprint of the mower enabling you to store it in areas with restricted space.
