The flail mower hammers are mounted on a sturdy bolt made of hardened steel of 25 mm diameter (overall length: 99 mm).

Close up of the cutting hammers that are already assembled on the rotating roller.

It is intended to finely shred grass and clippings, while rolling the grass cover and turf simultaneously. Thanks to the high number of rotor revolutions and the number of hammers (hammer flails), it allows reducing the wave impact of the grass cover and performing excellent shredding operations.

The rotating roller where are assembled the hammers features a diameter of 107 mm.

Side belt transmission and geared reducer

Gearbox in oil bath The external housing is made in fusion material while the internal gears are in hardened steel. Equipped with lubricated extension.

This machine is equipped with a freewheel device (or overrunning coupling) integrated in the gearbox. This feature ensures long durability to all the moving parts of the machine, avoiding the kickback that would be created from 540 rpm to 0 rev/min. Thus, it allows the rotor to rotate freely until reaching a total stop.

3-Belt side transmission (most of the tractor flail mower belonging to this weight category are normally equipped with 2-belt standard transmission)

Focus on the side belt protection cover.

Recommendations for Use - Tractor-mounted Fixed Flail Mowers

To ensure correct operation, a longer service life and safe working conditions, it is essential to use the tractor-mounted flail mower in accordance with the instructions set out in the user manual and the machine’s technical specifications. Incorrect use may result in premature wear of components, reduced performance or damage not covered by the warranty.

Before starting work, always check that the tractor is compatible with the flail mower by verifying the required power, hitch type and intended operating conditions. Correct matching of the machine and the tractor ensures optimum performance and prevents the transmission from being overloaded.

  • Use the flail mower exclusively on suitable surfaces: the machine is designed for grass shredding, wild vegetation, plant residues and materials compatible with the machine’s category. Avoid contact with unintended objects such as stones, metal, plastic or other foreign bodies.
  • Adjust the working height correctly: maintaining an adequate distance from the ground reduces the impact on the cutting units and limits excessive stress on the machine’s structure.
  • Do not operate the machine where there are hidden obstacles or unsuitable ground conditions: ditches, stumps, exposed roots, loose stones or uneven ground can cause sudden impacts and damage to the cutting parts or transmission components.
  • Do not use the flail mower for operations other than shredding: the machine must not be used for earthmoving, ground levelling or other applications not specified by the manufacturer.
  • Always adjust the forward speed to suit the working conditions: excessive speed can reduce the quality of the shredding, increase vibrations and subject the machine to stresses greater than those for which it was designed.
  • Avoid using the machine on excessively damp material: wet grass or particularly damp vegetation can cause material to build up inside the machine, reducing its efficiency.
  • Do not force the tractor forward: if the rotor slows down, vibrations increase or cutting capacity decreases, speed must be reduced and the work adapted to the conditions of the ground and vegetation.
  • Check the condition of the cutting components regularly: worn, damaged or missing blades, hammers or other cutting elements can compromise the machine’s operation and increase vibrations during use.
  • Carry out periodic checks and routine maintenance: check that components are correctly tightened, inspect the condition of the transmission components and ensure the machine is generally clean to maintain its efficiency and safety.

Use of the power take-off (PTO):

The tractor’s power take-off (PTO ) must be used in accordance with the rotational speed specified by the flail mower manufacturer. An incorrect rotational speed may compromise the machine’s operation, causing overheating, accelerated wear or excessive stress on mechanical components.

When attaching and detaching the flail mower, the power take-off must always be disengaged and the tractor switched off. It is also necessary to check that the PTO shaft is correctly installed and has sufficient clearance to move freely while working.
