Flail mowers can provide a far better result to rotary slashers as they pulverise the material that they are going through leaving small fragments on the surface after mowing and not long strands of grass. Apart from providing a clean finish, the mulch that is produced assists in retaining moisture in the soil below and improves the organic make up of the top soil. Celli manufacture a wide range of sizes to suit tractors between 20 to 180HP and 1.2 to 5m cut.
