Powered by twin 40V Li-ion batteries delivering 80V of cutting power, the Cobra MX51S80V has been expertly designed in the UK to cater specifically for the changing conditions of the British lawn.

Powered by twin Samsung 40V 5Ah lithium-ion batteries and supplied with two fast chargers, the Cobra MX51S80V produces an impressive 80V of power to its brushless motor. A multi-function cordless lawn mower, the MX51S80V lets you choose whether to collect, mulch or side discharge with its 3-in-1 steel cutter deck.

The self-propelled lawn mower features a generous 51cm / 21in cutting width and an adjustable cutting height, adjusted via a single lever from 25mm to 75mm to suit mowing conditions.

In collection mode, grass is deposited into a spacious 60 litre grass bag. A mulch plug allows you to finely chop the grass clippings and recycle them back to the surface of the lawn. Additionally, a side deflector lets you side discharge the grass into neat rows. With the grass bag removed, you can also rear discharge.

Petrol-matching power without the noise, fuss, mess and fumes of petrol or the restriction of an electric power cord.

2 x 5Ah batteries AND 2 x fast chargers included


Lithium-ion Battery Power

The Cobra MX51S80V is powered by 2x Samsung 40V Lithium-ion batteries offering a quiet, yet powerful and lightweight combination. The Cobra 40V Lithium-ion technology means the tool is always ready to use, suffers from no self-discharge and has no memory effect

Multiple Cutting Heights

With a fully adjustable 7 cutting heights ranging from 25mm for a superb low finish, up to 75mm for tackling longer grass, choose the Cobra MX51S80V. All this is achieved by simply using the single height of cut adjustment lever which has been conveniently positioned next to the rear wheels.


Large capacity grass bag for increased collection.

The Cobra MX51S80V cordless lawnmower is equipped with a 60ltr fabric grass bag, ideal for collecting large amounts of grass clippings before the need for emptying. The grass bag on the Cobra MX51S80V is made from a robust, high quality fabric. This fabric enables a strong free flow of air which means that grass collection on this machine is even more compact and comprehensive.

Start mulching

The MX51S80V 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. As the clippings decompose, nutrients and fertilisers are returned to the soil meaning you can cut the grass and fertilise at the same time.
