This cultivator pretends to be a subsoiler. So it does subsoiler work and thus fulfills the plow duty in LS19.
This is very practical, because this cultivator subsoiler is 18.2 m wide, which none of the real subsoilers can do. However, it does need a tractor with at least 500 hp to function.
Tested in FS19 1.6 version.
