Tandem knife roller for cutting catch crops for the tractor’s front hitch LUPUS
The 3.0 m wide LUPUS front 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. Rollers guards made of sheet metal are standard equipment. The machine weighs 820 kg, has a power requirement of 70-80 hp and an output of 2.5-3 ha/h. Axles fi 45 on UCF 209 bearings.
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.
Another advantage is the versatility of the frame of our rollers, as we can use as many as 16 different rollers on the same frame, which creates as many as 16 different machine configurations that we can adapt to the individual needs of our farmers and the variety of land they own..
Why is it so important to shred crop residues in maize stubble? The knife roller cutting solution.
– 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.
