Embankment flail mower for maintenance of rivers, canals, dams and streams


The Flail Mower FR 122 VB is based on a standard FR 122 model, which is equipped with a hydraulically driven conveyor belt that throws the cut-off material away from the work area.


The Flail Mower FR 122 VB is suitable for mowing embankments and ditches near water areas, such as streams, creeks, lakes, rivers, canals and dams. The hydraulic belt makes sure that the cut-off material does not end up in the water by launching it the opposite way towards the top of the bank. This will prevent overflooding and protect the pumping stations.


The conveyor belt is pulled hydraulically via the tractor’s hydraulics. It can drive both ways, simply by changing the rotation of the hydraulics. If you want to drive without the function of the belt, it can be folded up through a hydraulic cylinder.


The Integrated Airflow system is one of the main features of the FR series. The space between the rotor and the shield is purposely designed to increase the air velocity so the cut-off material exits the mower as quickly as possible. It creates a natural vacuum that sucks the grass into the mower. This increases the capacity of the flail head and reduces the power requirement.


The flail mower is available in a working width of 1.2 m (3'11") and are suitable for contractors and farmers that want the best mowing equipment in the market. You can achieve a driving speed of up to 7 km/h (4.35 mph) which enhances the efficiency significantly.


The main bearings are integrated in the rotor shaft which reduces the total width of the flail head. 


The machine is manufactured in Strenx 700 high strength steel which is one of the most durable steel types in the world. It is the same material that is used for chassis in the automotive industry. The flails are adapted to the rotor to stop breakage and damage from happening. These measures keep the maintenance costs at a low level.


The Flail Mower FR 122 VB is hydraulic driven and can be mounted on our Scorpion boom mowers for tractors or directly on the arm of diggers. When mounted on GreenTec’s Scorpion boom mowers, an integrated hydraulic hose set can be purchased.
