Product Information:

For garden enthusiasts looking for a strong and sturdy lawn mower, the Cobra Fortis 20B is a front runner in Cobra's strong line-up of petrol cylinder mowers.

Powered by a 127cc 4hp Briggs & Stratton XR550 engine that runs on the latest E10 fuel, this lawn mower has an easy recoil start and provides generous amounts of power to tackle the toughest of grasses.

With its 51cm / 20” cutting width and cutting height range of 6mm - 30mm, the Fortis 20B is easy to maneuver. This Cobra Fortis is controlled by a three-way drive system which allows the blades to be disengaged without having to stop the engine - convenient for emptying the large capacity 75ltr grass box situated on the front. Also, the ability to disengage the drive for manual control grants ease of movement around tight and awkward spaces.

As the UK is the only country in the world that has stripes on their lawns, the steel front roller and cast ribbed split rear roller provide an even, polished finish to your lawn,

Additionally, the Fortis 20B has a range of interchangeable attachments available, including verticut, scarifier, aerator, dethatcher, lawn brush, turf rake, and a 10-bladed cutting cylinder. This makes it easy to customise your lawn mowing experience and get your perfect cut.

The Fortis 20B is easy to transport and store thanks to its folding foam-cushioned handles, so you don't have to worry about it taking up too much space in your garage or shed.

With a 2-year domestic warranty, you can rest assured that you're investing in a quality product that will last.

Cobra, the perfect combination of power, style, and reliability. Every Cobra lawnmower has been expertly designed in the UK to cater specifically to the changing conditions of the British lawn.
