ABSTRACT:
A steel soil cultivating tine has a lower soil working portion and an upper fastening portion. The tine has zones of differing hardness along its length, the hardest zone including the lowermost end of the tine. The tine can take different shapes and configurations, but in general the soil working portion has sides, at least several of which taper towards the lowermost end. The fastening portion can be threaded for reception in a threaded holder. Near the juncture between the fastening and soil working portions a zone of reduced hardness lends flexibility to the tine.
