Sporting exceptional performance and style, the Cobra MX4140V cordless lithium-ion lawn mower allows you to get more mowing done without the need for petrol or the hassle of an electric cable. The Cobra MX4140V is hand-propelled, has a quality 41cm steel deck and is powered by a 4Ah 40V Samsung lithium-ion battery.

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

The Samsung 40 volt lithium-ion battery offers a quiet yet powerful and lightweight combination. Equipped with a battery power indicator, by simply pressing the power button, LED lights will give a visual display of how much power is left in the lithium-ion battery. The battery takes 80% charge in 45 minutes. Grass clippings are collected into a generous 50 litre fabric grass bag. The MX4140V also comes with a mulch plug to enable you to mulch your grass clippings back into the lawn, for a greener way to cut your lawn.

The lawnmower is still quite new, but overall I am very impressed. Compared to a petrol motor or traditional electric lawnmower, it is so easy to use. Build quality is solid and feels extremely well engineered. It is still light enough to be very easy to manoeuvre in tight corners. The one-lever mowing height adjustment is good, as is the battery charge monitor on the handle. The motor is powerful and cuts longer grass well, and it is smooth to operate (little vibration compare to petrol motor) and quiet. One of the biggest advantages I have found is that it is very quick to get ready to mow aND put away compared to the older motor types. The only part of the package I thought was not so good was the instruction manual. The photographs are blurry, the diagrams are poorly drawn and both sets of images are difficult to see the detail needed. In addition, some of the written instructions can be a little ambiguous. However, once assembled, I am very impressed. The only other question is how reliable it is over time.
