Professional Finish for Large Lawns & Sports Turf
The Cobra Fortis 25B is the largest model in the Fortis range, engineered for those who demand a flawless finish on extensive areas of fine turf. Powered by a robust Briggs & Stratton XR750 163cc engine, this mower delivers reliable performance and the power needed to maintain larger gardens, cricket pitches, bowling greens, and golf clubs. Its self-propelled, heavy-duty drive system ensures smooth operation and user-friendly handling, even across large, demanding terrains.
Precision Cutting & Perfect Stripes
At the core of the Fortis 25B is its 25-inch, six-bladed precision cutting cylinder, which provides a sharp, clean cut essential for lawn health and appearance. The cutting height is easily adjustable from a low 6mm up to 30mm using a single, conveniently located knob, allowing for the perfect lawn length. The classic striped finish is achieved with the steel front roller and a heavy-duty, steel rubber-coated split rear roller, which not only creates defined stripes but also aids manoeuvrability and prevents turf scuffing during turns.
Versatile Lawncare with Interchangeable Cassettes
The Fortis 25B is more than just a mower; it’s a complete lawncare solution thanks to its versatile interchangeable cassette system. While supplied with the standard 6-bladed cylinder, the system allows for the easy fitting of various optional cartridges to tackle a wide range of tasks. These include a 10-bladed cylinder for an even finer, lower cut (down to 3mm), a scarifier, aerator, dethatcher, verticutter, and a lawn brush. This adaptability makes the Fortis 25B an indispensable tool for year-round lawn maintenance.
Designed for Convenience and Durability
Every aspect of the Fortis 25B is built for convenience and longevity. The generous 90-litre grass box allows for longer mowing periods with fewer interruptions for emptying. For storage and transport, the mower features innovative quick-release handles that fold down easily without the need for tools. The entire machine is built with a heavy-duty drive system engineered to withstand demanding conditions, ensuring reliability and a long service life.

Frequently Asked Questions
What type of lawn is the Cobra Fortis 25B best suited for?
The Fortis 25B excels on large, fine-turf lawns where a pristine, low-cut, and striped finish is essential. It’s an ideal choice for large ornamental gardens, cricket squares, bowling greens, and other formal sports turf that require a professional-grade cut.
Is the interchangeable cassette system included with the mower?
No, the mower comes as standard with the 6-blade cutting cylinder cassette. The other optional cartridges, such as the 10-blade cylinder, scarifier, verticutter, or lawn brush, are available to purchase separately to expand the mower’s lawn care capabilities.
How is the cutting height adjusted on the Fortis 25B?
Adjusting the cutting height is very straightforward. It is controlled by a single, easy-to-use adjustment knob located at the front of the mower, which allows for precise height changes between 6mm and 30mm.
What is the main benefit of a split rear roller?
A split rear roller is divided into two or more sections that can rotate independently. This design makes it significantly easier to turn the mower at the end of each pass without scuffing or damaging the turf, helping to protect the lawn and maintain the integrity of your stripes.
