2026 Vaderstad CrossCutter Discs Aggressive 450mm

CrossCutter Disc provides full cultivation at only 2-3cm working depth. It’s unique cutting intensity crushes, chops and mulches in one single pass. CrossCutter Disc performs outstanding in oilseed rape stubble and in cover crops, while also enabling great advantages in grain stubble and on ploughed land.

The newest addition to the CrossCutter Disc family, the CrossCutter Disc Aggressive is developed for challenging field conditions. With its unique shape and sharpened TrueCut cut outs, CrossCutter Disc Aggressive excels in hard soils and in heavy residues where soil penetration might otherwise be an issue. All while still working ultra-shallow and moving substantially less soil than a conventional disc.

The topic field hygiene focuses on the post-harvest management of oil seed rape, cereals and other crops where the goal is to bring the seedbank to germination and the residues to decompose as fast as possible. A reduced seedbank improves the competitiveness of the following crop and may reduce the cost for herbicides. Ultra shallow tillage is also tested as a partial solution in case of the loss of glyphosate.

Many weed seeds, such as blackgrass are triggered by light. If buried too deep, they can stay dormant in the soil for many years. The CrossCutter disc throws the material upwards allowing it to sort when falling down. The lightest material, such as weed seeds, will then land on the surface where they encounter optimal conditions for a fast germinating. The stale seedbed can later be eliminated with a second pass, to provide great field hygiene for the next crop.

According to research, the depth of seeds of oilseed rape, weeds and grain directly affects the time needed for the seeds in the stale seedbed to germinate, grow and emerge. By reducing the time spent on waiting for the stale seedbed to emerge enough to be eliminated, means that the following crop can be drilled sooner. Alternatively, this additional time provides great opportunities for increasing the yield potential by conducting value-adding field work before the next crop establishment.

After cover crops and silage maize the mulching and incorporation of crop residues is crucial for success. To increase the cultivation intensity, CrossCutter Disc can be combined with the knife roller CrossCutter Knife. Using an aggressive packer such as a SteelRunner will further improve the cultivation effect.

When terminating a standing cover crop, a full cut-out at ultra-shallow working depth provides high capacity and great agronomical benefits. Working intensively at 0-3cm depth, crushes and mulches the cover crops without mixing the residues in depth. After one pass, the cover crops stems are crushed and access points for microorganisms are created. This fully eliminates the cover crop, while also minimising the risk for problems in the following crop.

After silage maize two main objectives needs to be fulfilled; destroy the habitat for the European corn bohrer and avoid the creation of mycotoxins that can be transferred to the following crop. CrossCutter Disc will achieve both tasks at a very low cost, increasing the breakdown rate compared to chopping the residues. A benefit compared to a mulcher, is that CrossCutter Disc also handles the residues in the wheel tracks.
