The expertly designed Cobra RM46B petrol lawn mower is equipped with the Briggs & Stratton 500 Series engine, which provides the best in-class performance for this category of engine and is suitable for gardens up to 600 square metres. This hand propelled lawn mower has a robust, high quality steel deck and features an 18" rear roller, which is perfect for creating that traditional striped finish right up to flowerbeds and borders.

The RM46B features 6 cutting heights which range from 15mm for an excellent low finish up to 75mm, which is perfect for tackling longer grass. The cutting height can be adjusted effortlessly, using a single lever which is conveniently positioned next to the rear roller. Another handy feature is the 60 litre grass bag, which is made from a robust, high quality fabric, allowing a free flow of air that ensures grass collection is comprehensive and compact. Its generous size means that large amounts of grass clippings can be collected before the need for emptying. The folding handlebar ensures easy storage.
