Hydraulic drive for versatile applications

Thanks to its hydraulic drive, the JANSEN® HMM-170 can be flexibly mounted on various carrier vehicles. The standard Euro mount allows for quick attachment to farm loaders, wheel loaders, tractors, and other vehicles with a compatible mount.

Operation requires a double-acting hydraulic connection as well as a drain line.

28 hardened hammer blades for clean mulching results

The 28 specially hardened hammer blades, each weighing approximately 400 g, reliably shred grass, weeds, shrubs, and small branches.

The spiral arrangement of the flails ensures even load distribution on the rotor. This ensures smooth operation and even intake of the cut material.

Robust Design

The front mulcher comes standard with a heavy-duty, height-adjustable trailing roller and two guide wheels at the front. This allows the cutting height to be easily adjusted to the respective operating conditions.

Free-swinging, galvanized slats at the front reliably prevent stones and cut material from escaping. Three V-belts also serve as overload protection for the drive.
