Loncin and B&S Engines

The Fortis range of cylinder lawnmowers are powered by Loncin and Briggs & Stratton engines, which are known for their reliability and ease of starting. These engines also offer improved efficiency and reduced emissions.

Power at your Fingertips

The ergonomically positioned operator controls on the Fortis range have many benefits such as reduced operator fatigue, increased safty and improved efficiency and control.

Split Roller with Differential

Fortis cylinder lawnmowers come equipped with either a smooth split rear roller, a cast ribbed split roller, or a rubber covered split roller. Driven by the heavy duty drive system, not only does this help create a beautiful striped finish, but the split roller makes the lawnmower more manoeuvrable, reducing scalping

6-30 mm Cutting Heights

By simply turning the easily adjustable height-of-cut know, mowing height can be adjusted from 6-30 mm giving you an incredibly fine finish to your lawn. Fortis lawnmowers cut shorter because they utilise a reel of 6 blades that rotate against a fixed blade, creating a scissor0like action that cleanly cuts each blade of grass.

Optional Turf Rake

The optional turf rake can help improve cutting performance. With the rake fitted, grass blades are lifted, resulted in a cleaner and more precise cut.

Optional Front Grooved Roller

The optional front grooved roller has less surface area in contact with the ground, and as a result more grass is presented to the bottom blade. The result is a cleaner cut to your lawn.

Large Capacity grass Box

Grass box capacity ranges from 55-90 ltires in the Fortis range, meaning more grass gets packed in a fewer trips to the compost bin for emptying. Fortis grass boxes are high quality, durable and robust.
