DISC INNOVATION

Since 2016, Maclouis has focused on machines with powered discs so that grubbing can be done with wide tyres or a wider bed with a narrower machine. Thus, the MLK3000 can be equipped with 6 hydraulically driven harvesting discs. These are suspended in a frame on a parallelogram. Spherical discs of 46 cm are mounted,
standing vertically at an angle of 45 degrees. 

Because the discs are driven, they give speed to the onions and they will come to rest between the next row of onions, which limits rolling back. 

The depth can be adjusted with an adjustable depth wheel between the rows. This ensures that the discs will always maintain the right depth whatever the topper does. The upper arms of the parallelogram are adjustable so that the frame can still be adjusted forwards or backwards. This allows a tractor to grub a 3-metre bed. Behind the tractor is a 1.80 or 2.25 grubber to sieve the soil and grub the remaining rows. 

The machine has a weight of 2300 kg. The three-point linkage is made adjustable so that the machine can be mounted as close to the tractor as possible for good weight distribution. This is also possible for a 225 haulm topper. The three-point linkage is then made 40 cm longer and 1 disc is mounted on both the left and right side of the topper, which then also hang in a parallelogram and the depth can be adjusted with a support wheel. This allows driving on wide tyres (48 cm). These discs can be hydraulically lifted for the spray track.
