Comfort Drive
Effortless control, enhanced safety.
Experience unparalleled control and manoeuvrability with Comfort Drive, an innovative steering system designed for ease of use and enhanced safety. This intuitive system utilizes a one/two-handed operation, separating the controls for direction and travel speed. This separation minimizes confusion and allows for independent control of each function, reducing operator fatigue and improving safety. With Comfort Drive, you can also set independent travel speeds for forward and reverse movement, providing exceptional precision and adaptability across various tasks and terrains.

Active Steering
Responsive handling, exceptional manoeuvrability.
Navigate with precision and agility using the responsive tie-bar active steering system. This system optimizes handling by allowing the operator to initiate cornering with a simple swivel of the control bar. The steering response is proportional to the swivel, meaning the further the bar is turned, the sharper the machine will turn. This intuitive design provides exceptional control and manoeuvrability, especially in tight spaces. With electric control, active steering is engaged for both forward and reverse travel, further enhancing the machine's agility and responsiveness.

Sliding Axis
Optimal balance, enhanced stability
Maintain perfect balance and stability on any terrain with the innovative shifting axis. This feature allows the operator to mechanically adjust the position of the axle based on the weight and size of the attached implement. By effectively distributing weight, the shifting axis ensures optimal traction and stability, even when working on slopes or with heavy attachments. This feature not only improves safety but also enhances the machine's performance and efficiency across a wide range of tasks.

Product Applications
Flail Mowing
Groundcare professionals are coming under more and more pressure to deliver a great finish with less annual cuts. With many types of mower, reducing the cuts results in clumps. Flail mowers allow you to mulch the grass finely and drops the grass more evenly, leaving a better finish in these applications. Flails will also allow you to mow more dense material and vegetation such as brambles, thistles and other weeds.

Winter Maintenance
Keeping pavements and highstreets open is also a challenge, often undertaken by council teams. A Kersten Plough or Spreader can allow facilities, key bus stops and other transport networks to remain accessible to pedestrians.
