Abstract: A dirt shield for a rotary digger such as a roto tiller includes a shield member mounted outwardly of a rotary earthworking member rotatably mounted on the digger for keeping dirt away from plants adjacent the digger and enabling rows in a field or plot to be planted closer together. The shield member is mounted on a framework supported from the shaft of the digger and anchored to the frame of the digger by a suitable supporting element. In the conventional arrangement of a rotary digger with two or more earthworking members, a pair of shield members will be provided, one to each transverse side of the digger.
