CatrosXL compact disc harrows

As an alternative to the coarse-serrated 610 mm convex discs which are ideal for large quantities of plant matter and have a good self-driving ability, AMAZONE also offers finely serrated discs which ensure, even at shallow operation, soil movement over the entire working width and a finely crumbled seedbed.

The discs are individually suspended and protected from damage via sprung rubber mountings that also ensure good ground contour adaptation. The maintenance-free, oil-immersed bearings on the discs are identical with those found on the Catros compact disc harrows and have been proven many tens of thousand times over and, like all other Catros models, the position of the bearings mean that they are protected from the soil flow. The disc stagger of 12.5 cm and the steep 17° angle of attack on the front row of discs and 14° at the rear row ensure an overall tilling effect and a perfect mixing-in of organic matter and the perfect penetration into the soil.

For a clean matching to the next bout when driving track to track, the new CatrosXL are equipped with individually-adjustable side discs. In the 3 and 4 m versions these discs can be simply folded in for road transport to maintain the relevant transport width.

Simple adjustment of the working depth
The working depth of the discs is similar to that found on the third generation Catros 03, where the complete disc carriers are rotated with the aid of four-sided link arms. When re-adjusting the working depth, this link arm connection between the first and the second disc row always ensures that both gangs of discs work at the same depth. Any adjustment can be carried out, from choice, either mechanically via setting spindles or during work from the tractor cab via the more comfortable optional hydraulic actuation.

Linking to the tractor
The tractor linkage system on the CatrosXL offers a high level of flexibility. The coupling of the lower link arms is carried out via a Cat. 3 pin. However, by simply reversing the pin in the lower link journal, a spacing of either Cat. 3 or Cat. 2 can be achieved. Two different mounting heights are available for the top link pin.

Wide roller programme
Depending on ground conditions and soil type, and to ensure optimum soil contact, the new CatrosXL can be combined with ten different rollers for reconsolidation and depth guidance. For operation on medium and changeable soils, the wedge ring roller is available whereas, for working on sandy soils, the UW U-Profile or DUW double U-Profile rollers offer the best solution. And especially suited to heavy and clay soils is the WW angle profile roller with knives or the DW Disc Roller. For use in seedbed preparation there are many other rollers available as well as a tined following harrow.
