advantage high performance at low operating costs; reduction of production costs; contribution to the natural process of fertilization: crushed stubble residues start the work of microorganisms faster; the possibility of using cutting blades in a checkerboard pattern; the possibility of weighting down with water; aggregation with tractors of class 1.4; high operating life of blades is achieved due to the use of 65G steel and volumetric heat treatment; rapid transfer of the unit to a working or transport position.
