A rotary tiller was a type of farming technology used to cultivate soil for farming. In the early 22nd century, an example of a rotary tiller was the 1102 cultivator.
32 of these tillers were loaded onto the colony ship SS Mariposa prior to its launch from Earth in 2123. These tillers were later used by colonists in the agricultural colony founded on Bringloid V. (TNG: "Up The Long Ladder")
