This is a conservation chisel plough that mounts the chisel plough tine. The frame consists of a cutting coulter, tine, and depth control roller. This frame was designed for the Africa market where farmers have small tractors and plant in virgin soil. The purpose of the Wajanja is to loosen the soil on the row that will be planted. Due to only disturbing the soil in the planting row, this implement is classified as a conservation tillage implement. The word Wajanja is the Swahili word for “bakgat”/clever.
