Powered by a Briggs & Stratton XR550 engine, the Fortis 20B is designed for larger lawns where a high-quality finish and long lasting, defined stripes are a priority.

The self-propelled Cobra Fortis 20B is powered by a reliable 4hp Briggs & Stratton XR550 Series™ engine and has an easy recoil start and heavy-duty drive system. The Fortis 20B also benefits from blade brake clutch which disengages the blade rotation without stopping the engine. This Saves you from switching off the mower and starting the engine again and again during a single session.

It features a generous 51cm cutting width, with the cutting height adjusted easily via a single screw from 6mm – 30mm.

The combination of a steel front roller and split-differential, smooth steel rear roller helps to produce those beautiful, classic stripes that are the hallmark of a cylinder lawn mower.

The Fortis lawncare cartridge system is a versatile system available for all Fortis lawnmower models.

Cartridges are fitted with the minimum of effort and including the standard 6-bladed cylinder, 10-bladed cylinder, scarifier, aerator, dethatcher, verticutter, and lawn brush that will keep your lawn looking its finest throughout the year. Whatever the garden task, the Fortis cartridge range will have a tool to complete the job.

It comes with a 2 year domestic warranty.
