The onion harvesters are ideally suited for onion sets and seed onions. The machines are characterised by their robust construction and come very well equipped standard. A square harvester shaft lifts the onions out of the ground. On both sides of the harvester shaft there is a 65 cm diameter coulter disc that ensures that the onions do not end up in the track. Next to the disc, the harvester chisels are mounted. These make room for the harvester shaft bearings. The harvest chisels are positioned so that the machine will always go into the ground. The first sieving mat is equipped with fixed beater rollers, so that the onions on the first mat are well shaken apart. Under the second sieving mat, a solid pressure roller with a scraper is mounted to level the ground under the machine, so that the onions end up on a flat bed and can be easily picked up again during loading. The clever positioning of the wheels at the rear means the harvesters are
guaranteed to be stable. With adjustable, bottom - following skids, it is possible to create a windrow, allowing the onions to be dried optimally. As a safety feature, a slip clutch is fitted in the PTO shaft to prevent overloading your machine.
Available in 1.50m - 1.80m - 2.25m
Clearing wider beds
With the MLR1800-S With the MLR1800-S onion harvester it is possible to dig up beds of 2.25 meters wide. This harvester has a working width of 1.80 meters and is equipped with two driven discs. These discs bring in the outer rows of onions so that they are already within the working width of the harvester in front of the harvesting shaft. They are then picked up from the bed at the same time as the other rows of onions. With a harvester with a working width of 2.25 meters it sometimes happens that the shears in front of the lifting shaft bearing throw the soil up to the next row of onions. Because a narrower machine is used, this is not the case with the MacLouis MLR1800-S onion harvester. The harvesting shaft is also 40 mm instead of 45 mm, so that harvesting is less deep.
Harvesting onions on wide tires
With the onion haulm toppers and onion harvesters from MacLouis it is possible to harvest onions on wide belts. MacLouis has developed a trestle for this purpose, which is mounted between the tractor and the front haulm topper. This is a 70 cm trestle to which the discs are mounted. The rows of onions are brought in in front of the wheels by means of discs, creating a tramline where a tractor can drive on wide tires. The discs run on their own and can move up and down. Behind the tractor comes a 1.50 onion harvester to pick up the other rows of onions and to sieve the soil.
Adjustable swath spreader
It is possible to equip the onion harvester with a hydraulically driven swath spreader. This allows onions to be stored in different ways. The harvester is then equipped with hydraulically adjustable deposit belts, which make it possible to deposit the onions to the side. Middle delivery remains possible. The swath spreader can also be used as a collecting bunker.
