Disc harrows can now apply the mulched field state when working on stubble. This simulates the light chopping and mixing of crop residues during shallow tillage.
This allows you to gain the 2.5% mulching yield bonus without using a separate mulcher pass, for crops where this method remains realistic.The effect is not applied to high-residue crops such as maize, sunflower, cotton and sorghum. These crops still require a dedicated mulching step if you want to apply the mulched state.
