On this day in 1913 Addison Ketring was granted the patent for PULVERIZER. U.S. Patent No. 1,080,010.
This invention relates to agricultural implements and has special reference to an attachment to cultivators for pulverizing the soil after the same has been operated upon by the cultivator.
This item has advanced since 1913 and is now referred to as a roller. The roller is used to flatten land or break up large clumps of soil, especially after the fields have been plowed. The roller was originally pulled by animals such as horses or oxen but is now pulled by a tractor.
Pulverizing the land or making it flatter allows for weed control which makes harvesting easier. The roll also helps to reduce moisture loss from cultivated soil.
