F rom a proven platform with more than 30 years of development behind it to a versatile machine designed for today’ s diverse grounds maintenance requirements, the new Trimax FlailDek S4 builds on what has made the range successful while introducing practical improvements for modern operators.

A proven platform, continually evolving

The FlailDek story began in the mid-1980s, when a customer approached Trimax with a request to front-mount a Trimax Ezeemow on a Yanmar 186 tractor. The concept demonstrated the potential of front-mounted flail mowing, eventually leading to the first FlailDek prototype in 1994 and full production in 1998.

Since then, each generation has evolved in response to customer feedback and practical innovation. The latest Series 4( S4) continues that philosophy, combining the proven FlailDek platform with improvements designed to reduce maintenance, improve efficiency and enhance usability.

The approach has also earned recognition at this year’ s GroundsFest Awards, where the FlailDek S4 has been shortlisted in the Stood the Test of Time category, recognising products that demonstrate enduring excellence through incremental improvements to a proven design.

Designed to do more

While mowing remains at the heart of the FlailDek S4, its versatility extends beyond conventional grass cutting.

Optional Y flails provide a finer finish in certain applications, while scarifying knives and the ability to set a negative height of cut introduce dethatching and scarifying capability. The converter flap can also be repositioned to switch between versatile mowing and specialised mulching applications.

The result is one machine
