Disc harrow is a universal machine. It can be used for cultivation after plowing. The machine is ideal for growing field with plenty of crop residues, ie. grain maize, rape or a catch crop. All this thanks to the increased distance between the rows of discs – with too small distance of crop, residues will block rotation of the discs. In disc harrow is also possible to adjust the rake angle of the disc – it is used for different soils. With heavy soils it is advisable to reduce the rake angle of the disc to reduce friction while pulling machine on light soils rake angle may be greater.
