Set of counter-knives

This flail mower offers excellent cutting and shredding performance of grass materials and branches.

The shredding chamber features a series of counter-knives which guarantee an optimal crushing of the material. The counter-knives are comb-shaped to ensure excellent and effective shredding performance, while the rotor is equipped with supports for the shredding hammers.

The set of counter-knives are applied under the hood and work together with the hammers, acting as a counter-blade for better shredding.

Rotor, reinforced hammer flails supports, side bearings

It is intended to finely shred grass and clippings, while rolling the grass cover and turf simultaneously.

Thanks to the high number of rotor rpms and hammers (hammer blades), the wave effect on the grass is reduced, resulting in an excellent cutting job.

The extremely sharp hammers allow for an excellent cut in gardens, lawns and urban areas.

The flail mower is mounted to the rear on the tractor's three-point-hitch.

The cutting roller has a diameter of 108 mm.
