Featuring powerful performance and a stylish design, the RM514SPC petrol lawn mower is powered by a Cobra DG600 engine with recoil start, is self-propelled with a four-speed transmission and equipped with a rear roller to produce a beautiful, traditional striped finish.

The 173cc engine offers a quiet, yet powerful and lightweight combination for a variety of demanding applications and the changing conditions of the British lawn. The steel deck lawn mower has a generous 51cm (20") width of cut with six cutting heights ranging from 17mm for a superb low finish, up to 75mm for tackling longer grass. The height of cut is adjusted simply by using the single height of cut adjustment lever conveniently positioned next to the rear roller.

A superior feature of this model is the high lift blade which spins to cause suction to effectively lift the grass, cut it cleanly and the airflow then blows the grass clippings back into the large 70 litre grass bag. The grass bag is made of a robust, high quality fabric which enables strong, free airflow resulting in more compact and excellent collection.

The Cobra RM514SPC lawn mower has a full width rear roller which helps to create a striped lawn. As the rear roller supports the lawn mower when the front wheels are in line with the border edge, it allows you to mow right up to the edge of flowerbeds and borders.

The Cobra RM514SPC four-speed rear roller petrol lawn mower, with its powerful engine and generous cutting width, offers superb value for money and is backed by a two year manufacturer's warranty for domestic use. The self-propelled system takes all the effort out of pushing your lawn mower so you can maintain your lawn and not feel exhausted when the grass cutting is complete.

Excellent service from start to finish, especially considering we were in the middle of the virus lockdown period. I ordered my mower on the Weds lunchtime and it was delivered the next day. I had a few questions to ask pre-order re- my short list of mowers and they were all answered very satisfactory. The mower, a very heavy 20” cut petrol model was very well packaged and the delivery guy was happy to carry it through my garage to the back garden. There was very little to assemble and it was ready to use in a relatively short time once I had read the instruction manual(s), filled with petrol, oil and petrol additive (supplied). I did notice a flaw in the mesh of the grass bag and reported it immediately, the response was, again, what you would expect but don’t always get, I was told to go ahead and use the mower and they would send out a new one next day, no need to return the original. I have only used the mower, the RM514SPC 20” once to date, so I can’t really comment on its performance and reliability longterm, but it does seem to be a really well built machine, and I am very pleased with my purchase.

The mower was delivered on time and was easy to put together. I've used it 3 times already and apart from a bit of manoeuvrability issues (going round corners) due to the weight of the roller it does a great job. Starts first time and cuts the lawn quickly (right to the edge) due to the width of the cutter. I'd recommend to anyone.
