Flail Mower X Series 2.4m


excluding VAT

Kellfri’s Flail Mower X-Series 2.4m is a robust flail mower with sturdy chassis and SKF ball bearings for 90-100 hp tractors.

The X-series are built to face tougher and rougher terrain. They are designed to cope with the demanding work they are exposed to. Practical for flailing, topping or cutting medium-sized or large grasslands and grassed areas.

Fast rotation

The fast rotation speed ensures that the forged hammer flails can easily hack and cut all types of material. Giving a dependable machine that is efficient for large material flows. The flail mower has a coarse-toothed welded counter bar in the chassis to break up the grass more effectively.  The detachable counter blades keep the grass in the machine and enable more material to be cut.

The flail mower is fitted as standard with hammer flails. There are 18 flails in total. The flail mower is also adapted for Y-flails, which can be purchased additionally.

Adjustable support roller and chain guards

Cutting height can be adjusted by the support roller and skids. The adjustable support roller guarantees a correct cutting height on uneven ground. Cutting height can be adjusted between 0-70 mm. Enabling you to cut grass close to the ground and achieve a more level result. The support roller has a scraping iron to keep the roller free from cut material. The support roller is built into the chassis to cope with tough terrain. It’s protected in the event of collision with obstacles.

The front of the flail is fitted with chain guards that adapt to the substrate and protect both the tractor and the surroundings from stone chipping and grass spray.

Hydraulic side shift adjustment 

The mower is equipped with hydraulic side shift adjustment. This enables you to shift the machine to the left or right. The side shift adjustment means that you can cut at the side of your tractor and reach areas that would otherwise be difficult to reach. The hydraulic side shift adjustment enables you to drive with just one pair of wheels in the uncut area and cut closer to ditches, fences, etc.

Openable flap

The mower has an openable flap. You open the flap when you are cutting or topping ground that generates a higher flow of material. This enables you to drive freely under the same conditions as with a closed flap and a normal flow of material. You save on fuel and reduce wear on the belts, and you can also operate at a higher speed, as the grass does not become twisted around the roller. The grass is also spread more evenly.

The flail mower’s chassis is made of 6 mm thick steel, and the side plate is 10 mm thick.


The flail mower X-series 2.4m is supplied with a PTO drive shaft, transmission oil, hydraulic cylinder and hydraulic hoses as standard.

The mower requires one double-acting hydraulic outlet on the tractor. The flail mower is supplied with two hydraulic ½ inch, quick coupling male hoses.
