ABSTRACT:
A soil working tool in the form of a streamlined tool 10 having a concave ridge-like edge 11 extending along a major portion of the length of the tool and being equipped with recessed holes 12 and 13 so the tool can be secured to a shank. The tool has a relatively narrow deep body including a leading toe section 14 which is square and bevelled at 15. The body diverges rearwardly to a heel 16 and the ridge-like edge 11 is upright and inclined rearwardly and extends from a point 17 in close proximity to the toe section 14 for the full length of the tool to an upper end 18.
The ridge-like edge is initially shallow and then has a relatively pronounced change in inclination about one third the way along the ridge-like edge but is still generally monotonically curved to provide a uniform action over the length of the tool.
