The invention of the Harrow
American History
The Harrow
A spring-tooth harrow, sometimes called a drag harrow, is a type of tine harrow, and is a wayy outdated piece of farm equipment. It uses a bunch of little flexible iron teeth put in rows to loosen soil before planting crops. It's set in the ground and raised manually and cannot be backed up; so it has been replaced by more modern farm things like the chisel plow and field cultivator.
