This article provides an excellent coverage of the history of stubble mulch equipment from 1933 to present. Starting in 1933 with Hoeme's cultivators for deep primary tillage that left clods on the ground, Noble's (1936) undercutting tiller, and in 1939, Russell and Duley began experimenting with a tiller that would cut off weeds at subsurface while leaving straw residue on the surface. This became known as stubble-mulch tillage. With the use of stubble mulch tillage came the advent of shovel press drills and eventually air-seeders.

The spring-tine harrow is an implement used in Europe for mechanical weed control in field crops such as wheat. Recent preliminary field tests in Wisconsin found control to range from 40-90%. A similar implement may be available from Lindsay Bros. in Des Moines, IA. It reportedly does not perform well with much surface residue.
