The Cobra RM513SPBI is equipped with the world's first lawn mower engine to combine the power of petrol and the starting reliability of lithium-ion battery technology. The mower is powered by a Briggs & Stratton 675iS Series™ InStart®  engine for effortless starting every time.

This model is self-propelled with a three-speed transmission and equipped with a rear roller to produce a beautiful, traditional striped finish. The 163cc single cylinder, four-stroke OHV (overhead valve) engine offers a quiet, yet powerful and lightweight combination to power through a variety of demanding applications and the changing conditions of the British lawn.

Equipped with a premium steel deck with a generous 51cm (20") cutting width, it features 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 RM513SPBI 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 RM513SPBI three-speed rear roller petrol lawn mower has a self-propelled drive system which takes all the effort out of pushing your lawn mower so you can maintain your lawn and not feel exhausted when the mowing is done.

Excellent mower good quality build and does a lovely job, the only reason I have not given 5 stars is the grass collector - it is not up to the quality of the rest of the machine and the plastic clips tend to come off the steel frame, which is annoying when its full. If you handle it carefully it's OK, but spoiling the ship springs to mind!!!
