A welcome addition to the Cobra 40V li-ion range is the new RM4140V lawn mower. What is so special and totally unique about this model is that it is equipped with a full width rear roller. For the first time, you can achieve a traditional striped finish on your lawn with a battery-powered lawn mower. The roller also gives you the ability to mow right up to the edge of flowerbeds and borders.

The quality metal deck with a cutting width of 41cm (16") features seven fully adjustable cutting heights ranging from 25mm for a superb low finish, up to 75mm for tackling longer grass. Grass clippings are collected into a generous 50 litre fabric grass bag.

The Cobra RM4140V is hand-propelled and powered by a 4Ah 40V Samsung lithium-ion battery. The mower will run for up to 30 minutes (in ideal cutting conditions) on a single 90 minute charge.

The Samsung 40 volt lithium-ion battery offers a quiet yet powerful and lightweight combination, is an environmentally-friendly alternative to a petrol-powered lawn mower and gives you the freedom to mow without the restraints of an electric power cable. A built-in battery power indicator allows easy monitoring of battery life.

Works OK, assembly instructions are not very clear. Not sure the roller is very effective at making stripes (which was why I bought this model) but grass isn't growing much at the moment

I'm pleased with the Cobra RM4140V Cordless Lawn Mower. It cuts the grass well. It create stripes. It is a bit lighter than a petrol equivalent. It is quieter than a petrol mower, which I was surprised by as the quoted dB didn't seem low. I find charging the battery a lot more straight forward than buying and filling up with petrol. I also feel more at ease about stopping and starting repeatedly than I did with a petrol mower as it is so easy pressing a button rather than pulling a cord. Of course it doesn't produce the fumes of a petrol mower. It is not as maneuverable around objects as I would like but I suspect that's a trade off you except, to have the longer blade size allowing you to get the big areas done quickly and turning at the end of straight lines is easy enough. I am happy with it and would recommend it for a medium size lawn

This is a great mower! My last mower (petrol) lasted 25 years and this Cobra machine is a perfect (green) replacement. It's well made and works fine! Importantly, it has a roller and can cut very low to very high and this covers all my needs. Very well packaged and prompt delivery from the Green Reaper!

Wanted a cordless rear roller inexpensive mower to supplement a robotic mower for doing edging and occasional trimming grass if too long. Cobra RM 4140V fits this requirement. Promptly delivered and adequately packaged. The Green Reaper was very helpful.
