Cobra doesn't do things by halves with this superb addition to its range of environmentally-friendly cordless lawn mowers which is sure to be another award winner. 

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 (21") cutting width and the cutting height can be 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.

Proud to be supporting the cordless evolution, Cobra battery-powered mowers are packed with innovative features to help you maintain your lawn with the minimum of effort in the most environmentally-friendly way.  Petrol-matching power without the noise, fuss, mess and fumes of petrol or the restriction of an electric power cord.

A sturdy 51cm (20") steel cutter deck features seven fully adjustable cutting heights which range from 17mm for a low finish, up to 75mm for tackling longer grass. Raising and lowering the deck is achieved by simply using the central height of cut adjustment lever which has been conveniently positioned next to the rear roller so you can set the mower up to suit the mowing conditions.

The mower is equipped with a spacious 70 litre capacity grass bag, perfect for collecting a large volume of grass clippings before the need to empty.

The grass bag has a grass fill indicator which flaps until the bag is full and is made from a robust, high quality fabric which enables a strong, free flow of air making grass collection even more compact and comprehensive.
