A cultivator is both a general term for any tool that is used to prepare soil for planting, and the name of four specific tools: a piece of machinery attached to a tractor, a small engine-propelled machine, a hand-action tool, and a traditional hand-tool.
A cultivator is any of several types of farm implement used for secondary tillage. One sense of the name refers to frames with teeth (also called shanks) that pierce the soil as they are dragged through it linearly. Another sense refers to machines that use rotary motion of disks or teeth to accomplish a similar result.
