This flail mower model is equipped with sturdy antishock springs, designed to absorb shocks and vibrations when using the flail mower.

These springs are positioned between the flail mower and the tractor arm, offering various benefits in terms of comfort, performance and durability.

During work, the flail mower can be subjected to significant stresses and shocks due to obstacles, potholes, etc., which can be transmitted to the tractor arm and the operator. Anti-shock springs are designed to mitigate these shocks, reducing the impact on the mechanical parts of the mower and improving operator comfort.

They act as shock absorbers, absorbing the energy generated by shocks and redistributing it evenly along the tractor arm. This reduces pressure on flail mower components such as blades, bearings and gears, contributing to a longer service life and reducing the risk of damage or breakage.

In addition, anti-shock springs help to maintain a constant pressure of the blades on the ground, even under irregular stress. This ensures an even shredding and a clean cut of the grass or plants, guaranteeing a high quality result.

It finely shreds grass and twigs, while simultaneously rolling the turf.

Thanks to the high rotor speed and the great number of hammers (hammer flails), it reduces the wave effect of the turf and has an excellent shredding action.

Thanks to the sharpened toothed hammers, it ensures high-quality results in gardens, lawns and urban areas.

The supports at the ends of the rotor ensure stability thanks to their highly sturdy and solid nature.
