Cultivator Attachment.

Patent for improvement in cultivator attachments by using “a pair of cutting blades or knives adapted to be adjustably connected to the lister-beam after the plow-blades have been removed and after the planting of the field, and these knives are adapted to straddle the center row and to work down to three inches under the surface of the ground, extending half-way to the adjoining row on both sides of said center row, thus absolutely killing all grass, weeds or the like, and turning up just enough dirt to cover the scrub. By thus treating each row in succession a field may be cleared more quickly, more easily, and more thoroughly.” (Lines 15-27) Illustration is included.
