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

The Cobra RM51SP80V cordless Lithium-ion lawn mower allows you to get more done without the need for petrol or electrical cables & is part of a modern range of environmentally-friendly battery operated mowers. The mower is self propelled for easy operation & will easily match its petrol or electric counterparts for power, versatility, and value for money but with none of the fuss, fumes or noise of a petrol engine, none of the electrical cables to hold you back & zero guilt thanks to zero emissions & eco friendly performance!

The Cobra RM51SP80V is powered by two 5.0Ah 40V Lithium-ion batteries that power the 80v brushless motor, 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.

The RM51SP80V cordless lawnmower comes equipped with a self propelled drive system at a speed of 3.2km/h for added comfort and ease of operator use. The self propelled system takes all the effort out of pushing your lawnmower, meaning you can maintain your lawn with ease, even when mowing thick grass or cutting on an incline.

With a cutting width of 51cm/ 20", the Cobra RM51SP80V also has 7 adjustable cutting heights ranging from 17mm 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 rear roller series of petrol lawnmowers from Cobra all come equipped with a full width rear roller to help produce a traditional striped finish. The RM51SP80V also gives you the ability to mow right up to the edge of flowerbeds and borders as the rear roller supports the lawnmower when the front wheels are in line with the border.

In addition to its robust steel deck & rotary cutting blade, the Cobra RM51SP80V mower is equipped with a 60ltr fabric grass bag, ideal for collecting large amounts of grass clippings before the need for emptying. The grass bag is made from a robust, high quality fabric & enables a strong free flow of air meaning that grass collection on this machine is even more compact and comprehensive.

The Cobra RM51SP80V also features a folding handlebar making it easy to put away after use, saving precious space & ensuring safe, compact storage.
