Cobra Fortis 20B 51cm/20" Self-Propelled Petrol Cylinder Lawn Mower

Offering strength and versatility for gardening enthusiasts with medium to large lawns, the Fortis 20B forms part of Cobra's strong line-up of petrol cylinder mowers and will deliver the finest cut and pristine appearance to a domestic lawn, emphasised with sought-after lawn stripes.

The Cobra Fortis 20B features a generous 51cm (20") cutting width and six-bladed precision-ground cutting cylinder which achieves enviable results with a scissor-like cutting action at a remarkable 79 cuts per metre. This versatile lawn mower benefits from an interchangeable cassette system to allow the cutting cylinder to be quickly removed and replaced with a range of optional lawn care accessories.

The combination of a steel front roller and cast, ribbed, split-differential rear roller helps to lay down those traditional stripes that are the hallmark of a cylinder lawn mower. If your lawn incorporates flower beds, the rollers also let you overhang the lawn edge slightly so you can mow right up to the edge without the risk of the blades scalping the lawn. The cutting height can be adjusted from an exceptionally low 6mm up to 30mm via a single screw so you can select the ideal mowing height for your chosen area and the conditions.

The front-mounted grass box has a large 75 litre capacity and provides efficient debris collection and easy emptying. Convenient folding handles allow for easy transportation and compact storage. 

Powered by a reliable 4hp Briggs & Stratton XR550 Series™ engine which runs on the latest E10 fuel, the self-propelled Fortis 20B has an easy recoil start and heavy-duty drive system. The Fortis 20B also benefits from blade brake clutch (known as BBC) which disengages the blade rotation without stopping the engine, saving you from switching off the mower and starting the engine again and again during a single session. This feature also allows you to move the lawn mower between areas of grass without the blades turning, which comes in handy when you need to cross a gravel driveway or a paved path, empty the collection box or wish to stop mowing to remove some obstacles on the way. 

If you strive perfection by regularly maintaining your ornamental or domestic lawn, then the Cobra Fortis 20B will prove to be a quality, versatile mower also capable of a wide range of essential turf maintenance tasks throughout the year. 

Lawn care attachments which can be fitted in place of the standard cutting unit include a verticut, scarifier, aerator, dethatcher, aerator, dethatcher, lawn brush and 10-bladed cutting cylinder. The ability to remove the blade cassette also assists in the easy and economic maintenance of the lawn mower. A grooved roller is also available which can be fitted in place of the smooth front roller, as well as a turf rake to help improve cutting performance.
