Primary tillage equipment performs the following functions except

Primary tillage equipment performs several functions in preparing the soil for planting, including turning over and inverting the topsoil, burying weeds and trash, and preparing the soil for secondary tillage. However, it is not primarily responsible for preparing ridges for planting. This is the job of secondary tillage equipment, such as bed shapers or furrowers. Primary tillage equipment is used to break up hard-packed soil, loosen compacted soil, and create a suitable seedbed for planting. It is typically heavier and more powerful than secondary tillage equipment and is used less frequently, usually only once a year or every few years, depending on the soil type and cropping system.
