Knife roller 4.0 m hydraulically folded LUPUS

Knife roller 4,0 m hydraulically foldade on the front/rear linkage of the tractor LUPUS

The 4.0 m wide LUPUS knife roller is made up of two cutting rotors with a diameter of Ø 380 mm. Each rotor consists of six segments on which cutting knives made of 8 mm hardox are mounted. Roller guards made of sheet metal are standard equipment.

The weight of the 4.0 m machine is 1520 kg. We are able to produce any width of roller on request.

Due to the high speed and high number of cuts per revolution, the post-harvest cutter roller effectively shreds crop residues on maize stubble. The machine can also be used successfully on stubble fields after other crops, e.g. oilseed rape, and is excellent for removing tall catch crops that are difficult to cover even with deep winter ploughing.

The Lupus tandem knife roller can be used alone as well as in combination with other finishing machines attached to the tractor’s rear linkage. The machine can work at a speed of 5-20 km/h and the recommended working speed is above 12 km/h, the working depth should not exceed 3 cm.

Why is shredding crop residues in maize stubble so important? The solution is to cut with a roller knife.

– The destruction of maize stalks in the field destroys the habitat of the corn borer larvae, in which it burrows for the winter.

– The shredded plant residues decompose in the soil much faster, but if they are not broken up, they interfere with further agro-technical operations, because even a plough equipped with skimmers cannot cope with the combine harvester residues.

– Especially on heavy soils, the ploughing up of undecomposed residues will result in very slow decomposition due to lack of air supply and the formation of a layer of “felt” that blocks water absorption and is a barrier to the development of the root system of the next crop.
