Kisankraft KK IC-307D Diesel Inter Cultivator, 6HP 296 cc
A cultivator is any of several types of farm implement used for secondary tillage. One sense of the name refers to frames with the teeth(also called shanks) that pierce the soil as they are dragged through it linearly. Another sense refers to machines that use the rotary motion of disks or teeth to accomplish a similar result. The rotary tiller is a principal example.
