Cordless Freedom, Cylinder Precision
The Cobra Fortis 17E represents a new era for lawn enthusiasts, blending the immaculate cut of a traditional cylinder mower with the convenience and power of modern battery technology. Powered by EGO’s renowned 56V system, it delivers a precise, quiet, and emission-free mowing experience. Its 17-inch (43cm), six-bladed cutting cylinder provides a scissor-like action that is kinder to the grass, promoting a healthier, denser lawn. With a variable cutting height from a low 6mm up to 30mm, this mower is perfectly suited for homeowners with medium to large lawns who aspire to achieve a finely manicured, professional-looking striped finish.
Advanced EGO Power & User Control
At the heart of the Fortis 17E is EGO’s unique ARC-shaped battery design and KeepCool™ Technology. This system works to lower temperature and prevent overheating, ensuring consistent power, performance, and run time. The mower features a user-friendly LCD display screen integrated into the control panel. This high-resolution screen provides clear, real-time information, allowing the operator to monitor travel speed and battery power status. It also includes an hour meter, which helps in managing maintenance schedules and tracking usage over time.
Engineered for a Perfect Finish
Every component of the Fortis 17E is designed to contribute to a flawless lawn. It features a robust steel front roller and a heavy, cast iron split-ribbed rear roller, which not only creates those desirable classic stripes but also aids stability and manoeuvrability. The heavy-duty drive system is engineered for durability and smooth operation, even in demanding conditions. Grass clippings are efficiently collected in the large 65-litre grass box, which is designed for superior collection and easy removal, allowing for longer mowing sessions with fewer interruptions.
The Complete Lawncare Solution
The Fortis 17E’s versatility extends beyond just mowing. It is fully compatible with the Fortis interchangeable cartridge system, transforming it into a complete, all-season lawn maintenance tool. These optional cartridges allow you to perform a range of essential tasks to keep your lawn immaculate and healthy. Available cartridges include a verticutter, scarifier, dethatcher, aerator, lawn brush, and an even finer ten-blade cylinder for an exceptionally low cut.

Frequently Asked Questions
Who is the Cobra Fortis 17E best for?
The Cobra Fortis 17E is ideal for lawn enthusiasts with medium to large-sized gardens (up to around 500m²) who want to achieve a high-quality, pristine striped finish without the noise, emissions, and maintenance associated with petrol cylinder mowers.
What is included in the Fortis 17E kit?
This kit includes everything needed to get started: the Fortis 17E mower itself, the standard 6-bladed cutting cylinder, a 65-litre grass box, two EGO 56V 5.0Ah batteries, and a standard EGO battery charger.
How long does the battery last on a single charge?
With the two included 5.0Ah batteries, you can expect an approximate run time of up to 60 minutes. Please note that this can vary depending on factors such as grass length, density, and ground conditions.
What is the Fortis interchangeable cartridge system?
It is a range of optional cassettes that can be swapped with the main cutting cylinder. These cartridges allow the mower to perform other essential lawn care tasks, such as scarifying, dethatching, aerating, and brushing, making it a highly versatile, all-season machine.
Can I get an even lower cut with this mower?
Yes. For those seeking the ultimate low cut, an optional 10-bladed cutting cylinder cartridge is available to purchase separately. This cartridge can achieve a very fine cut down to 3mm, which is perfect for ornamental lawns or sports turf like bowling greens.
