bull tongue

(b) A scooter or "bull-tongue" is a strip of iron used in opening the furrow for the cotton seed.

The common plow was a “bull-tongue,” which has aptly been described as “hardly more than a sharpened stick with a metal rim.”

This Mexican bull tongue plow has an iron shoe on the point and it closely resembles Spanish plows of the 16th century.

They are of the bull-tongue variety, and are sometimes drawn by oxen.
