Spring-Tooth Harrow

           A spring-tooth harrow or drag harrow more specifically refers to a largely outdated type of soil cultivation implement that is used to smooth the ground as well as loosen it after it has been plowed and packed. It uses many flexible iron teeth usually arranged into three rows. It has no hydraulic functionality and has to be raised and adjusted with one or multiple manual levers. It is a largely outdated piece of farm equipment, having been replaced by more modern disc harrows and deeper, stiff-toothed rippers, however, smaller farmers still use them.

          It was invented by David L. Garver in 1869. It was created because soil was quite rocky, so the spring-tooth harrow was a machine that dug the rocks out or derockatized the ground. This machine made it easier on the farmer to work. It helped to produce more product and was faster. It also helpegetting to the market quicker and getting more of the supply there. It gave the ground better nutrients and easier to plant things.
