Grubber having reversible coulters

摘要

Grubbers are equipped in an easy to maintain manner with coulters which are connected to the respective tines only by means of a screw and which have extensions on the face confronting the tine for the purpose of preventing rotation. These extensions correspond to a recess in the tine, the particular lower extension being supported on the tine tip so as at the same time to protect the latter. The coulter tips have plane working faces which are connected to the slightly bent middle part. <IMAGE>
