Types of Farm Equipment and Their Uses | Holt Ag Solutions

While the soil has to go through several subsequent steps to be ready for planting, plowing is an essential first step. The concept of a plow may seem simple enough, but there are a variety of different plow types. Each plow type is suited to a specific soil type, soil condition and crop type. Here is a look at the three most common types of plows:
